A window replacement quote is a written price proposal that identifies every opening by location, size, and style; specifies the product, glass package, and installation scope; and states the total before any work starts. Anything less detailed than that is not a quote you can compare. It is a number, and two numbers for the same house can differ by thousands of dollars without either contractor doing anything wrong.
The reason is almost always scope, not margin. One contractor prices an insert replacement and another prices full frame. One includes disposal, sealing and interior finishing, and the other assumes you will handle the trim. One quotes triple glazing with argon and low emissivity coating, and the other quotes double glazing with neither. Before you can decide which quote offers better value, you have to confirm both describe the same job. Most of the confusion in this process comes from skipping that step.
This article explains what a complete quote includes, how the Alberta Consumer Protection Act changes what you sign when you sign a contract at your kitchen table, how to compare two or three quotes on equal terms, and what to do when a line item is missing. It is written for homeowners in Calgary and Edmonton who are still in the research stage.
Key Takeaways
- A quote and an estimate are different documents with different legal weight. In Alberta, the difference is concrete: the Consumer Protection Act says you cannot be charged more than 10 percent above an estimate, to a maximum of $100 over. A detailed quote, once signed, fixes the scope and the price.
- A contract signed at your home can be cancelled within 10 days. Where a written contract is solicited, agreed or signed away from the contractor’s normal place of business, the Act gives you 10 days from receiving your copy to cancel, with no reason required. Signing in a showroom is different, and the right does not apply the same way.
- Every opening needs its own line. A quote listing ten windows without the room, size, style, frame colour and glass package for each one cannot be verified or compared. Ambiguity in a quote tends to be resolved later in the contractor’s favour.
- Labour should be separated from product. When labour is folded into a per-window price, you cannot tell whether a cheaper quote reflects a cheaper unit, less installation work or both.
- Omissions are where the surprises live. Disposal, foam sealing, exterior capping, interior finishing and permits are all legitimate line items. If they are not written down, ask whether they are in or out before signing.
- Two or three quotes are the working standard. Fewer than two leaves you without a reference point. More than three rarely changes the decision and costs you several evenings of appointments.
- Warranty terms belong in the document. Get the product warranty and the labour warranty in writing, including duration, what each covers, and whether the product warranty transfers to a future owner.
How the Quoting Process Works
A quote begins with an in-home consultation. Someone visits, measures each opening, assesses the condition of the existing frames, and discusses what you want the windows to do. For a whole house, that visit usually runs one to two hours. The written document follows within a few days, though a straightforward scope with complete measurements can sometimes be priced the same day.
The measuring is the part worth watching. Measure every opening at several points: width at the top, middle, and bottom; height on both sides and in the centre. Openings in older houses are rarely square, and the smallest dimension is the one the new unit has to fit. A contractor who measures once per opening, or who prices without visiting, is producing a figure rather than a quote, and the difference will surface on installation day.
Insert Replacement Compared With Full Frame
The consultation also determines which type of replacement your openings need, and this single decision moves the price more than any other. An insert replacement removes the sash and glass and fits the new unit inside the existing frame. A full frame window replacement removes everything down to the rough opening, including the frame, sill, and exterior trim, which means more labour, more finishing, and more materials.
Neither is better in the abstract. An insert is appropriate where the existing frame is square, sound, and dry. A full frame is necessary where the frame has moved, rotted, or been compromised by water, and it is the only option that lets an installer inspect and correct what is behind the trim. For quoting, decide which one you want before anyone prices the job, because otherwise you’ll compare two different scopes and read the difference as a price difference.
Quote or Estimate: What Alberta Law Actually Says
People use the two words interchangeably, and most online advice describes the distinction loosely. In Alberta, it is not loose. The Consumer Bill of Rights sets out your right not to be charged more than 10 percent above an estimate, to a maximum of $100 over. That is a statutory ceiling on estimate overrun, not a rule of thumb, and it applies whether or not the contractor mentions it.
A detailed quote works differently. Once you sign it, the scope and price are fixed, and changing either requires a written change order that you agree to. So the practical question when you receive a document is not which word appears at the top. It is how much detail it contains, because that determines whether the price can move afterward and by how much.
What You Are Signing at Your Kitchen Table
The window industry has a well-documented pattern of same-day pressure: the quote is presented, a discount is attached to it that expires when the salesperson leaves, and a signature is requested before you have compared anything. Most advice on this subject tells you not to sign at the first appointment. That is sound advice, but in Alberta there is something more useful than advice.
The Consumer Protection Act treats a contract solicited, agreed or signed away from the contractor’s normal place of business as a distinct category. Where that applies and the purchase is over $25 and intended for personal, family or household use, you may cancel within 10 days of receiving your copy of the signed contract. You do not have to give a reason. If the tenth day falls on a Sunday or a statutory holiday, you get an additional day.
Three details in that rule are worth holding onto. The first is where the clock starts: it runs from when you receive your copy, not from when you signed, which is why you should insist on leaving the appointment with a copy in hand. The second is the location test. A contract signed at your kitchen table is covered. A contract signed in the company’s showroom generally is not, because that is their normal place of business. The third is that you cannot waive these protections. A contract clause saying you give up your rights under the Act does not remove them.
The Act also names high-pressure sales tactics, misleading statements about a good or service, and gross overcharging as unfair practices, and gives you a right to cancel within one year if a business is found to have used one. None of this means you should sign and rely on the cancellation window. It means the pressure to sign tonight has far less force than it appears.
Check the Licence Before the Deposit
There is a second requirement that almost no homeowner knows about and that applies to nearly every window company. Under the Consumer Protection Act, a business that concludes a contract away from its own premises and accepts money before the work is finished is a prepaid contracting business, and it must hold a prepaid contracting licence from Service Alberta and Red Tape Reduction. To hold that licence, you must post security with the province.
Read the definition and compare it to how window sales actually work. The contract is signed at your kitchen table, and a deposit is taken because the units are built to your openings and cannot be resold. That combination puts almost every window company in the province inside the definition. A municipal business licence is a different thing and does not satisfy it.
Asking for the prepaid contracting licence number is a short question with a long payoff, because the companies that disappear with a deposit are overwhelmingly the ones operating without one. Service Alberta also recommends checking references, confirming liability insurance, documenting every contract change in writing, and using a traceable payment method rather than cash. Workers’ compensation coverage is worth confirming for the same reason: a clearance letter from WCB-Alberta confirms a contractor’s account is in good standing, and getting one before work starts protects you from liability for unpaid premiums.
What a Complete Quote Contains
Every Opening, Specified Individually
Each window entry should name the room or location, the size in millimetres and inches, the style, the frame colour and the glass package. An entry that reads “living room, 914 mm by 1219 mm, 36 by 48 inches, casement, white, triple pane, low emissivity, argon” is something you can hand to another contractor and ask them to price. An entry that reads “10 windows” is not.
Name glass specifications rather than imply them. A low-emissivity coating is a thin metallic layer on the glass surface that reflects radiant heat, and in Alberta it is normally specified to hold heat inside through the winter rather than block summer solar gain. Argon is a dense inert gas sealed between the panes that slows heat transfer. Both should appear by name. Also ask for the U-factor, which measures heat loss through the whole assembly (lower is better), and the solar heat gain coefficient, which measures how much solar energy passes through the glazing.
Labour Separated From Product
Ask for installation labour as its own line. When labour is buried inside a per-window price, a lower total tells you nothing about why it is lower. Separated, you can see whether one contractor is using a cheaper unit, charging a lower installation rate, or planning less work at each opening.
Every Scope Item Listed, Included or Excluded
These are the items that produce the arguments later, and every one of them has a real cost attached:
- Removal and disposal of the existing units
- Foam sealing and caulking at the perimeter
- Exterior capping or trim
- Interior finishing, including drywall repair where required
- Permits and inspection fees, and who is responsible for obtaining them
- Whether the stated total includes GST or excludes it
A quote that omits these is not necessarily excluding them. It may simply be an incomplete document. Either way, the fix is the same: ask in writing whether each is in or out, and add the answer to the comparison.
“The thing I see most often when homeowners bring me a competitor’s quote is that the two documents are not actually pricing the same job. One includes disposal, the other does not. One is quoting insert; one is quoting full frame. They look at the total and conclude one company is cheaper, but they are not comparing the same work. I spend more time explaining that on a first visit than almost anything else.” – Chris Perry, Project Manager, Weather Pro Windows and Doors
Lead Time and Scheduling
Replacement units are manufactured to the measurements taken at your house, which means there is a build period between signing and installation. The quote should state the expected lead time and, where possible, a target installation window. A document that fixes the price but says nothing about when the work happens leaves you with a commitment and no schedule.
Two things are worth asking about here. First, what happens if the lead time slips: does the contractor notify you, and does the contract address delays? The second is seasonal. Installation continues through Alberta winters, because openings are done one at a time and closed the same day, but scheduling in January is a different conversation from scheduling in June, and demand through spring and summer stretches lead times across the whole market. If your project isn’t urgent, quoting in the off-season often brings better availability and more of the contractor’s attention.
Warranty Terms in Writing
A complete quote states the product warranty and the labour warranty separately, because they cover different things and often run for different periods. The product warranty covers the unit itself. The labour warranty covers the installation, which is where most early problems actually originate. Ask what each covers, how long each lasts, and whether the product warranty transfers if you sell the house. Lifetime warranty windows are a common offer in this market, and the terms behind that phrase vary considerably between companies, so read what is written rather than what is said.
Setting a Budget Before You Invite Anyone
What Actually Moves the Number
Before you can judge whether a quote is reasonable, you need to know what the price includes. Six factors account for most of the variation between two quotes for the same house.
- Size and opening count. Larger units cost more in glass and in handling, and a project with more openings usually carries a lower rate per window.
- Style. A fixed unit has no operating hardware. A casement carries an operator, hinges and a multi-point lock. That hardware is a real line of cost, which is why two openings of the same size can price differently.
- Glass package. Double versus triple glazing, the gas fill, the number of low-emissivity coatings, and any laminated layer all affect the unit price. This is the easiest place for two quotes to diverge without either being wrong.
- Replacement type. Full frame costs more than an insert, because it involves more removal, more materials and more finishing work at every opening.
- Access and floor level. Second-storey openings, units above a deck or a slope, and anything needing a lift take longer to install safely and are priced accordingly.
- Finishing scope. Exterior capping and interior drywall repair are labour lines, and whether they sit inside or outside the quote changes the total more than most homeowners expect.
Knowing those six is what lets you read a range rather than a number. Published figures on window replacement cost give you a reference point before the first appointment, and online estimators do the same with one caveat: they use averaged labour and material costs that may not reflect current pricing in Calgary or Edmonton, or the specific conditions of your openings. Use the range to spot a quote that sits well outside it, not as a figure to hold a contractor to.
Paying for It
Budget also affects scope in a way worth raising early. Replacing everything at once usually lowers the per-window cost and reduces disruption to a single project, while replacing in phases spreads the spend but repeats mobilization costs. If the total is the obstacle rather than the value, ask about window financing during the quoting stage rather than after you have narrowed the scope to fit cash on hand, because the two decisions interact.
Where the Process Differs
Comparing Two or Three Contractors
This is the common case and the one the whole document format exists for. The comparison works only when each quote covers the same openings, the same replacement type and equivalent glass. When those match, the price gap is real and reflects product cost, labour rate or margin. When they don’t match, the gap tells you about scope and nothing else. Most window companies in Calgary will quote to whatever brief you give them, so the brief is yours to standardize: decide the replacement type and lock in the opening list before the first visit.
Whole House Replacement
A whole-house project has a longer opening list, a larger finishing scope, and a real opportunity for volume pricing. Here, the quote functions as much as a project specification as a price, so list every opening individually, with its own style, size, and glass package confirmed in writing. Ask each contractor to show cost per opening alongside the total, because that breakdown reveals whether one or two openings are priced well above the rest, which usually means they involve more complex installation. When inviting window companies in Edmonton or Calgary to quote a project of this size, also ask directly whether the per-window rate changes with the total count, because it often does and it is easier to ask before the scope is fixed.
An Urgent Single Window
When a window has failed and has to be dealt with quickly, the priority shifts from comparison to clarity. You may not have time to collect three quotes, and that is a reasonable trade. What doesn’t change is the value of getting the scope in writing: the unit, the installation, disposal of the old window, and any finishing work. A verbal agreement about what is included is harder to rely on than a written one, and a single window job is not too small for a written document.
Replacement Quote Compared With Repair Estimate
Knowing which document you are asking for saves time on both sides. The table below sets out the difference, including how Alberta consumer law treats each.
| Dimension | Window replacement quote | Window repair estimate |
|---|---|---|
| What it is | A written price proposal to supply and install new units. Once signed at your home, it is a contract, subject to the cancellation rights in the Consumer Protection Act | An approximate figure for fixing an existing window, given before the fault is fully known |
| Detail level | Each opening listed by room, size, style, frame colour, glass package and installation scope | Based on limited information, often a single visit or a description over the phone |
| Scope | Removing the existing units and installing new ones, plus finishing, disposal and sealing | Addressing a specific fault: a sealed unit, a hinge, an operator, a lock |
| What is priced | Units, installation labour, removal and disposal, finishing, permits where applicable | Labour and parts for the identified fault only |
| Price certainty in Alberta | A signed quote fixes the scope and price unless you agree to a written change order | Under the Consumer Protection Act, you cannot be charged more than 10% above an estimate, to a maximum of $100 over |
| Cancellation right | If the contract was signed at your home rather than at the company premises, you can cancel within 10 days of receiving your copy, no reason required | The same rule applies to any contract solicited or signed away from the contractor’s normal place of business |
| When to ask for it | The frame is damaged, the unit no longer operates, or you are replacing on a plan | The frame is sound, and the fault is confined to glass, hardware or seals |
| Remaining uncertainty | Low once openings have been measured in person, though hidden damage behind trim can still surface | Higher by nature, because the full extent of the fault is often only visible once work starts |
The practical rule: if the frame is sound and the fault is confined to a sealed unit, a hinge or a lock, ask for a repair estimate. If the frame has failed, the window no longer operates, or you are replacing it as part of a plan rather than in response to a fault, ask for a quote.
Comparing Quotes Side by Side
The comparison is methodical, not intuitive, and the order matters. Do not start with the total.
- Confirm each quote covers the same openings. Count them and check the rooms match.
- Confirm the replacement type is the same across all quotes: insert or full frame.
- Compare the glass package opening by opening: glazing configuration, gas fill and low emissivity specification.
- Check each scope line individually. Disposal, sealing, exterior capping, interior finishing, permits.
- Add the cost of any missing item to the quote that excluded it, then compare the totals.
- Compare warranty terms last, because a longer warranty can justify a higher price and a shorter one can explain a lower one.
A simple table makes this manageable: contractors as columns, specification points as rows, one cell per answer. Filling the gaps means phoning each contractor with specific questions, which is also a useful test of how the project will be managed. A company that will not put an answer in writing at the quoting stage is unlikely to become more precise once the deposit is paid.
Patterns Worth Questioning
None of the following automatically means a contractor is unreliable. Each means the document isn’t yet complete enough to sign or compare.
- A total price with no line item breakdown
- A glass package described only as energy efficient, without naming the glazing configuration, gas fill or coating
- No mention of disposal, sealing or finishing anywhere in the document
- Warranty terms described in conversation but absent from the page
- A price that expires at the end of the appointment
On the last one, it is worth knowing that a discount which exists only while the salesperson is in your living room is a pressure device rather than a pricing decision. The Consumer Protection Act lists high-pressure sales tactics among the practices you have a right to be free from, and the 10 day cancellation right exists precisely because this pattern is common enough to legislate against.
Deposits and the Payment Schedule
The payment structure belongs in the comparison and is often left out. Ask what deposit is required, when the balance falls due, and whether any part of the payment is tied to a milestone such as delivery of the units or completion of the finishing work. A schedule that holds a meaningful portion back until the job is finished protects both sides, because it gives the contractor a reason to return and close out the small items that always remain.
Prepaid contracting, meaning an arrangement where money changes hands before the work is complete, is a category the Consumer Protection Act addresses specifically, and the same 10-day cancellation right applies where the contract was signed away from the contractor’s normal place of business. If you’ve already paid a deposit and cancel within that window, you must refund it. This is another reason to keep your copy of the signed document and to note the date you received it.
A deposit is normal in this industry, because units are built to your openings and cannot be resold. A request for the full amount up front is not, and it is a fair question to ask why the schedule is structured the way it is.
Questions to Ask Before the Contractor Leaves
The consultation is when answers are cheapest. Once the quote is written and the salesperson has moved on, every clarification costs a phone call and a wait. Nine questions cover most of what usually gets missed:
- Are you quoting insert or full frame, and why did you choose that for these openings?
- What is the whole-window U-factor for the glass package you have specified, and is the figure in imperial or metric units?
- Does the price include disposal of the existing units, including hauling away the glass?
- How is the perimeter sealed, what flashing goes in at the sill, and is interior finishing part of your price?
- Who obtains any required permits, and is the fee included in or outside the total?
- What are the product and labour warranties, and does the product warranty transfer to a buyer of the house?
- What is the deposit, when is the balance due, and is any part held back until completion?
- If something unexpected turns up behind the trim, what is the change-order process, and who authorizes it?
- Is the total on this page before or after GST, and what is your prepaid contracting licence number?
Every one of those has a short answer, and a contractor who cannot give nine short answers at the kitchen table is describing how the rest of the project will go. Write the answers on the back of the quote before you put it away, because in two weeks you will not remember which company said what.
What a Quote Cannot Tell You
Three things sit outside even a complete document, and it is better to know them going in.
What is behind the trim. An in-home consultation reduces uncertainty considerably, but nobody can see inside a wall assembly without opening it. Rot in a sill, a compromised header, or water damage in the sheathing can show up once the old unit is out. Ask each contractor how they handle that: a written change order process agreed in advance is a very different experience from a phone call on the day.
How the installation will actually be done. The quote names the product. It rarely describes the perimeter air seal, the flashing at the sill, or how the frame will be shimmed, and those details determine how the window performs far more than the product sheet does. Ask about them explicitly, because they are usually the difference between two quotes that look identical on paper.
Whether the permit position is correct. Permit requirements depend on the municipality and whether the opening size changes. A like-for-like replacement is treated differently from an enlarged opening or a new one cut into a wall. Contractors are generally right about this, but the homeowner often bears responsibility, so confirm the position with your municipality rather than relying on the quote alone.
The Document Is the Product Until the Windows Arrive
Until installation day, the only thing you actually have is a piece of paper, and its quality is a fair proxy for how the project will run. A quote that lists every opening, separates labour from product, states what is included and excluded, and notes both warranties reflects a company that works in a specific way. A single total with no breakdown is also telling you something.
Standardize the brief, collect two or three documents, compare on matching specifications before you compare totals, and take the quotes away rather than signing at the table. If you do sign at home and change your mind, the Consumer Protection Act gives you 10 days from receiving your copy. That is the floor, not the plan, but knowing it is there removes most of the urgency the process is designed to create.
Frequently Asked Questions
What should a window replacement quote include?
Every window listed by room, size, style, frame colour and glass package. Installation labour shown separately from product cost. A clear statement of whether removal and disposal, foam sealing, exterior capping, interior finishing and permits are included or excluded. Product warranty and labour warranty terms in writing, with durations and whether the product warranty transfers. Anything less detailed cannot be verified or compared against another document.
How many quotes should I get before choosing a contractor?
Two or three is the working standard for a residential project. That range gives you enough reference points to see pricing patterns and spot scope differences without spending several weeks on sales appointments. Fewer than two leaves you with nothing to compare against. More than three rarely changes the decision for a straightforward job, and every additional appointment costs you an evening.
Why do quotes vary so much between companies?
Usually because they are not pricing the same job. Product line, glass package, insert against full frame, and what the installation scope includes all move the total. A quote covering disposal, exterior capping, interior finishing and permits will cost more than one excluding them, even when the window unit is identical. Establish that both documents describe the same work before concluding one company is simply cheaper.
Can I cancel a window contract after I sign it in Alberta?
In many cases, yes. Where a written contract is solicited, agreed or signed away from the contractor’s normal place of business, such as at your home, the Consumer Protection Act allows you to cancel within 10 days of receiving your copy of the signed contract, with no reason required, provided the purchase is over $25 and intended for personal, family or household use. If the tenth day falls on a Sunday or a statutory holiday, you get one more day. A contract signed at the company’s premises is treated differently, and these rights cannot be waived by a clause in the contract.
Can a contractor charge more than the estimate?
Under Alberta law, not by much. The Consumer Bill of Rights sets out a right not to be charged more than 10 percent above an estimate, to a maximum of $100 over. That applies to estimates. A signed quote works differently: the scope and price are fixed, and any change requires a written change order you agree to. If a contractor says a figure is likely to change substantially, ask which document you are being given.
Do I need a permit for window replacement in Calgary or Edmonton?
It depends on the work, not the city. Replacing a window in an existing opening at the same size is treated differently from enlarging an opening, cutting a new one, or altering anything structural above it. Requirements and fees vary by municipality and can change, so confirm the current position with your municipality and have the quote state explicitly who is responsible for obtaining any permit and whether the fee is included in the price.
Can I negotiate a window replacement quote?
Yes, and it is considerably easier with two or three comparable quotes in hand. Matching specifications gives you a factual basis: you can ask a contractor to match a competitor’s price for an equivalent specification, or adjust the scope to bring the total within budget. Negotiation based on a specification comparison tends to work better than negotiation based on the total alone, because it gives the contractor something concrete to respond to.
