Typical 2026 prices for windows and doors
GTS Windows & Doors is a Kitchener window and door installer that has served homeowners, landlords, property managers and builders across Waterloo Region since 1986. We measure, quote and install replacement windows, entry doors and patio doors in Kitchener, Waterloo, Cambridge, Guelph and the surrounding townships, and every job carries our 20-year parts and labour warranty. As a licensed, insured and WSIB-covered SAWDAC member, we price work the way we install it: opening by opening.
Most cost guides that turn up in local searches are written for Toronto, where labour, parking and access costs run higher and the housing stock is different. The ranges on this page reflect what Waterloo Region jobs typically cost in 2026, covering the product, removal of the old unit, installation, insulation, trim and disposal. They are built around the homes we see most here, from postwar brick bungalows and 1990s two-storeys to century homes near the downtown cores.
Every house is different, so treat these figures as typical ranges rather than a quote for your home. This guide was last updated in September 2026, and we revise it when product and labour costs move. An on-site measure is the only way to get an exact, itemized price for your openings.
Prices below assume white vinyl frames, double pane Low-E glass with argon, and a standard retrofit installation with new interior trim and exterior caulking or capping. Bay and bow prices include the seat board, head board and insulation, but a new roof over the bay is extra.
Casements and awnings cost more than sliders of the same size because they add cranks, hinges and multi-point locks. If you are weighing a full set of new units, our window replacement page walks through the process from measure to final walkthrough.
| Window type | Small (under 10 sq ft) | Medium (10 to 20 sq ft) | Large (over 20 sq ft) |
|---|---|---|---|
| Single or double slider | $550 to $850 | $750 to $1,150 | $1,000 to $1,600 |
| Single or double hung | $650 to $950 | $850 to $1,250 | $1,100 to $1,700 |
| Casement | $700 to $1,000 | $900 to $1,400 | $1,300 to $2,100 |
| Awning | $650 to $950 | $850 to $1,300 | $1,100 to $1,700 |
| Picture (fixed) | $500 to $800 | $750 to $1,200 | $1,100 to $2,000 |
| Bay window (3 sections) | Not typical | $3,500 to $6,000 | $5,000 to $8,500 |
| Bow window (4 or 5 sections) | Not typical | $4,500 to $7,500 | $6,500 to $10,000 |
Frame material changes the price more than any other single choice. This table compares a medium casement installed with the same double pane glass package.
| Frame material | Typical installed price, medium casement | Compared with vinyl |
|---|---|---|
| Vinyl | $900 to $1,400 | Baseline |
| Fibreglass | $1,300 to $2,300 | About 30 to 60% more |
| Solid wood, primed | $1,300 to $2,500 | About 40 to 80% more |
| Thermally broken aluminum | $1,400 to $2,800 | About 50 to 100% more |
| Aluminum-clad wood | $1,500 to $3,000 | About 60 to 110% more |
Upgrading from double to triple pane typically adds $100 to $250 per average window in 2026, roughly 10 to 20 percent. On large picture windows and patio doors the premium is higher because the extra glass is heavier and needs stronger sashes and hardware.
Triple pane pays off most in bedrooms, north-facing rooms, homes on busy roads and houses you plan to keep for many years. Our page on triple pane windows covers the comfort, condensation and noise trade-offs.
| Glass package | Typical added cost per medium window |
|---|---|
| Double pane, Low-E, argon | Included in the prices above |
| Double pane with laminated or extra Low-E coating | $75 to $250 |
| Triple pane, two Low-E coatings, argon | $100 to $250 |
| Triple pane on a large picture window or patio door | $250 to $600 |
Door prices include the pre-hung door and frame, removal of the old unit, installation, insulation, interior casing and exterior sealing or capping. Hardware, glass inserts and paint colours move the final number.
A standard steel front door typically costs $2,000 to $4,000 installed, and fibreglass runs $2,800 to $5,500. Sidelights, decorative glass, multi-point locks and smart hardware push the price toward the top of the range. Our entry door replacement page compares the options in detail.
Replacing a sliding patio door typically costs $2,500 to $4,500 for a standard 5 or 6 foot vinyl unit. Wider, three-panel, triple pane or fibreglass doors run $4,000 to $7,500, and hinged garden doors cost more again. See sliding patio doors for styles and glass options.
| Door | Typical installed price (2026) |
|---|---|
| Steel entry door, single, pre-hung | $2,000 to $4,000 |
| Fibreglass entry door, single, pre-hung | $2,800 to $5,500 |
| Entry door with one or two sidelights | $4,500 to $9,000 |
| Double entry doors or custom wood | $6,000 to $12,000+ |
| Vinyl sliding patio door, 5 or 6 ft | $2,500 to $4,500 |
| Sliding patio door, 8 ft, 3-panel or triple pane | $4,000 to $7,500 |
| Hinged garden or French patio door | $4,500 to $9,000 |
Two quotes for the same number of windows can differ by thousands of dollars. These factors explain most of the gap.
Same-size replacements usually need no building permit in Kitchener, but enlarged openings and designated heritage properties can. Our permit and heritage guide for Kitchener explains which jobs need approval and how that affects timing.
These are illustrative scopes based on common Waterloo Region house types, not specific past projects. They show how the per-window prices above add up for a full job.
| Home and scope | What is included | Typical total (2026) |
|---|---|---|
| 1960s brick bungalow, 10 windows | White vinyl casements and sliders, double pane Low-E argon, retrofit install, aluminum capping | $9,000 to $14,000 |
| 1990s two-storey, 16 windows and a patio door | Vinyl casements with triple pane glass, 6 ft sliding patio door, retrofit install | $18,000 to $28,000 |
| Townhouse, 7 windows and a front door | Vinyl sliders and casements, steel entry door with sidelight | $11,000 to $17,000 |
| Century home, 12 windows | Wood or clad wood with heritage profiles, full-frame install, new interior trim | $28,000 to $50,000+ |
| Newer home, 20 windows with black exteriors | Fibreglass casements and picture windows, triple pane | $35,000 to $55,000 |
The lowest total is not always the cheapest job once exclusions are added back in. Line up quotes using these five checks, and see our guide to choosing a window company for the questions to ask the installer.
An itemized quote lists every opening with size, style, glass and price, so you can compare line by line. A single lump-sum number hides where the money goes and makes scope changes hard to price.
Check whether each opening is quoted as retrofit or full-frame, and how the gap will be insulated and flashed. Install method alone can move the price of one window by hundreds of dollars.
Confirm that removal, disposal, interior trim, exterior capping and caulking are included. These are the items most often left off low quotes and added later.
Ask for the manufacturer, product line and ENERGY STAR model for each window. You need them for rebates and to be sure you are comparing similar products.
Separate the manufacturer's product warranty from the installer's labour warranty and check the length of each. GTS covers parts and labour for 20 years.
Ontario's Home Renovation Savings program pays $100 per ENERGY STAR window or door rough opening when you complete a home energy assessment and at least two eligible upgrades. Eligibility depends on how your home is heated and who supplies your gas, so read our window rebate guide before you plan around it.
Homeowners in Cambridge and North Dumfries who are GrandBridge Energy customers can apply for low-interest RetrofitWR loans that cover energy-efficient windows and doors. If financing matters to your decision, raise it when you request a quote so we can factor it into the plan.
In Waterloo Region in 2026, most standard vinyl replacement windows cost about $650 to $1,400 each installed, with large and specialty units costing more. Fibreglass, wood and aluminum typically cost 30 to 100 percent more than vinyl. Toronto prices tend to run higher because of labour and access costs.
A typical three-bedroom home with 12 to 16 windows and one door usually lands between $14,000 and $28,000 in vinyl, depending on glass, install method and the door you choose. Fibreglass or wood packages can reach $35,000 to $55,000 or more. An itemized quote is the only way to know your exact number.
Usually, yes. Measuring, ordering, delivery, crew setup and disposal are shared across the whole order, so the price per window drops, and the glass and colour stay consistent. If the budget is tight, doing the worst elevation first and the rest within a year or two is a reasonable compromise.
Demand peaks in the fall, so late winter and early spring can mean shorter lead times and more flexible scheduling. Product prices rarely drop by season, so the bigger savings come from ordering several openings together and choosing standard sizes and colours. Windows can be installed year-round, one opening at a time, even in January.
Installation labour alone typically runs $200 to $450 per window for a retrofit install and $350 to $700 or more for full-frame replacement in 2026. Brick openings, second-storey access and custom trim add to that. Most installers price supply and installation together, and many will not warranty windows bought elsewhere.
Book an on-site measure and we will price every opening separately, with product, glass, install method and trim spelled out. You will know exactly what you are paying for before you decide.
