- Insert replacement, double pane
$900 to $1,300 per opening - Full frame replacement, double pane

A new slab hung in the existing frame costs less, usually $1,500 to $2,500 installed, but it keeps the old frame's draughts and sill, and the tested performance figures only apply to the full system.

$2,800 to $4,500 - Three or four panel sliding door
$4,500 to $7,500 - Hinged garden door
$3,500 to $5,500

What affects your price
Four things move the new window price.
Size of the opening
The single biggest factor. A basement hopper and a living room bay are not remotely the same job, and glass area drives most of the cost.
Glass package
Dual glazed is the standard and is already Energy Star certified. Triple pane costs more per opening, which is why we price it per window instead of per house.
Style and material
Casements cost more than sliders because of the hardware. Fiberglass doors cost more than steel. Architectural shapes are custom by definition.
Install complexity
Full frame costs more than an insert. Second storey, brick exteriors, and anything needing capping or new trim all add labour.
In numbers
What each factor adds.
- Full frame instead of insert
about 15 to 25 percent more - Triple pane
$150 to $300 per opening - Second storey access
$50 to $150 per opening - Rot or framing repair
priced after we open the wall, before we continue - HST
13 percent on top of every figure here
Rebates and incentives
Energy Star glass as standard.
The stock Guardian Low-E 80/71 glass package is Energy Star certified across the whole range, so there is no upgrade to buy to reach the efficiency levels rebate programs look for.
We supply the documentation and invoices the programs ask for. Which rebates are actually running changes year to year, so ask at the estimate and we will tell you what is live.
Financing
Payment terms.
Thirty percent on order covers manufacturing. The balance is due after the walkthrough, once you have seen the finished work. Nothing is owed at the estimate.
Pricing questions
Window replacement pricing questions, answered.
How much does it cost to replace windows in Ottawa?
A replacement window runs roughly $900 to $1,800 per opening installed, before HST. That is $900 to $1,300 for an insert replacement and $1,200 to $1,800 for a full frame replacement, both double pane, and it covers removal, disposal, and finishing the trim inside and out. Triple pane adds $150 to $300 per opening, and a bay or bow is a different job again at $3,000 to $6,500. Because each opening is quoted separately, five windows is roughly $4,500 to $9,000 and twelve is roughly $10,800 to $21,600.
How much does a front door cost installed in Ottawa?
A steel entry door system runs $2,500 to $4,500 installed, and fiberglass $3,500 to $6,500, before HST. That is the whole system, including a new composite frame, sill, weatherstrip and multi point locking hardware, not just the slab. With one or two sidelites the system runs $4,500 to $8,000. Transoms are priced separately, and the glass collection you choose moves the number within the range.
How much does a patio door cost in Ottawa?
A two panel sliding patio door runs $2,800 to $4,500 installed, a three or four panel sliding door $4,500 to $7,500, and a hinged garden door $3,500 to $5,500, all before HST and with screens included. A low threshold and integrated blinds are options within those ranges. Widening an existing opening is structural work and is quoted apart from the door itself.
Does the price include HST?
No. Every figure on this page is before HST, which is 13 percent in Ontario. A $3,000 job comes to $3,390 with HST.
Why will you not give me a firm price over the phone?
We will happily tell you the ranges above, and they are on this page so you do not have to ask. What we will not do is turn a range into a firm number without measuring, because that is a guess, and a guess that comes in too low is how people end up with change orders halfway through the job. We measure first, then price, then the number stops moving. That order matters.
Can the price change after I sign?
Only if you change what you ordered, or if we open a wall and find rot or framing damage that was not visible at the measure. In that case we stop, show you the problem, and price the repair before doing anything. You decide whether it goes ahead.
Why is the deposit 30 percent?
The windows and doors are manufactured to your measurements and cannot be resold, so the deposit covers the order. Nothing is owed at the estimate, and the balance is due only after you have walked every opening with us.
Are you the cheapest?
Probably not. There is almost always someone quoting less, usually by using a thinner product, skipping the trim work, or leaving the disposal to you. Compare the quotes line by line and it usually becomes clear what has been left out.
Do I have to do the whole house at once?
No, and pricing each opening separately is exactly what makes that possible. Plenty of homeowners do the worst four or five now and the rest in a couple of years. We will tell you which ones are actually urgent.
