Toronto Projects
Toronto's housing stock is unforgiving. Century-old Victorian brick semis with settled, out-of-square openings sit blocks from post-war bungalows with undersized basement windows, midtown semis with heritage-sensitive facades, and lakeshore condos and towers with sealed-unit and balcony-door failures. Each era needs a different install method — and we've done all of them here. Common Toronto projects include casement window, tilt & turn, and bay window replacements, along with steel and fiberglass entry doors, sliding patio doors, full masonry work, code-compliant egress windows, and Toronto permit assistance. Flexible financing is available, or you can request a free quote any time. See what Toronto-area homeowners say about working with us.

Trust Build Windows and Doors provides professional replacement-window and door installation across Toronto, including North York, Scarborough, Etobicoke, East York, York, Midtown and Downtown Toronto. We measure each opening, build the units to fit it, and install with our own crews.
We have worked on Toronto houses since 2016: Victorian brick semis with openings that have settled out of square, post-war bungalows with undersized basement windows, midtown semis where the street-facing elevation has to keep its character, and infill builds where the window goes in during framing. The method changes with the house. What follows is how we decide, what the glass and hardware actually are, and where the permit questions come up.
Replacement Windows
Most Toronto replacements we do are vinyl replacement windows: insulated, foam-filled vinyl frames don't conduct cold the way aluminum does, they don't need painting, and they hold their shape through repeated freeze-thaw cycles. Aluminum and wood are available where the architecture calls for them — heritage elevations in particular. Every unit comes in double or triple glazing, ENERGY STAR® certified for Ontario's climate zone.
The operating style is chosen room by room, not house-wide:
Side-hinged, cranked open, and one of the tightest seals available — the most common choice we install in Toronto living rooms and bedrooms. Fixed casement units give the same thermal build without an opening sash. See casement windows.
Top-hinged and opening outward, so air still gets in during light rain — kitchens, bathrooms and basements. Awning windows.
Sliders suit wide openings and modern elevations; single and double hung windows keep the vertical proportions older Toronto streets expect, which matters on a street-facing wall.
No moving parts, so the highest thermal performance of any style, and the most glass for the opening. Picture windows.
Angled or curved projections that are rebuilt rather than swapped — head, skirt and side panels included. Bay windows, bow windows, and a side-by-side comparison of the two.
Built for below-grade conditions, and often paired with a window well rebuild or an egress conversion. Basement windows.
Installation
A premium window installed badly still leaks air and water, so the method matters as much as the unit. Toronto is really three housing markets stacked on one another, and each one tends toward a different approach.
The new window is set inside the existing exterior frame, which stays in place. It is faster, it leaves interior casing largely undisturbed, and it is the right call when the existing frame is sound, square and dry — much of the post-war stock through Leaside and Scarborough qualifies. The trade-off is glass area: the new frame sits within the old one, so you lose some sightline, which is noticeable on a small opening. More detail on retrofit window installation.
The existing window, frame, brick mould, jamb extensions and interior casing are removed so the opening can be prepared. The rough opening is cleaned and inspected — this is where hidden rot and failed insulation turn up — insulation is added where required, and Blueskin waterproofing membrane is applied per our installation standards. A fully assembled unit is then set into the rough opening, shimmed against the studs, checked plumb, level and square, and insulated around the full perimeter with low-expansion foam rather than only the visible gap. The foam is trimmed flush and taped, then the work is finished with new jamb extensions and interior casing inside, and exterior sealing with aluminum capping where applicable. The unit is fastened to the structural framing of the opening — not to the brick. Century semis in Leslieville and Riverdale, the early-1900s stock in the Beaches, and most of York usually need this method. Full walkthrough on brick-to-brick installation, and a direct comparison of the two methods.
On infill builds and gut renovations — plenty of them through Willowdale and the west end — the unit goes in during framing and the retrofit question never arises. See hybrid / split-frame installation and our installation methods overview.
We name the method after looking at the opening. If a company commits to one before anyone has seen the frame, ask why.
Toronto Housing Stock
Century brick. Openings in the older east- and west-end stock have had a hundred-plus years to settle. Frames go out of square, mortar joints move, and rot often sits behind casing that looks fine. These almost always want brick-to-brick so the new unit can be set square in an opening that no longer is. Plaster-wall interiors need their own care during removal — see our full-frame process.
Post-war bungalows and side-splits. Much of Scarborough, Leaside and North York has frames that are still sound, which makes retrofit viable. The recurring problem here is basement openings — small, low, and sitting in wells that hold water. That is a window well question as much as a window one, and sometimes an egress conversion if the room is becoming legal living space.
Bay and bow assemblies. Common across Etobicoke and midtown, and never a like-for-like swap. The projection has a head and a skirt, both of which need rebuilding and capping alongside the units themselves.
Masonry. Once the old frame is out, damaged brick, spalling and open joints around the opening become visible and need addressing before the perimeter is sealed. We handle that in-house through our masonry work rather than leaving it to another trade after the fact.
Permits and code. Like-for-like replacement frequently does not require a permit, while enlarging an opening, cutting a new one, altering structure above it, or creating an egress window generally does. Those requirements come from the City of Toronto Building Division and the Ontario Building Code and depend on your specific project — confirm the applicable requirements with the City before work begins. Where a permit applies we pull it and coordinate inspections; see building permits.
Pricing
Short answer: there is no single Toronto price per window, and we do not publish one. A replacement window is manufactured to the measurements of one specific opening, so the price follows the specification of that opening. Here is every factor that moves it, so you can read any Toronto quote — ours or anyone else's — and understand what you are paying for.
This is why an accurate Toronto number requires project-specific specifications: measured rough openings, a chosen method per opening, a glass package and a colour. We measure, then issue a written, itemized quote before anything is ordered — and we would rather do that than quote a per-window average that turns out to be wrong for your house. For a worked Ontario example of how scope and rebates interact on a ten-window project, see our Ontario ten-window cost and rebate breakdown, and financing options if the project is being spread over time.

Quote Checklist
Two Toronto quotes for “10 windows installed” can describe genuinely different projects. These are the line items that explain most of the gap — worth checking on every quote you collect, including ours.
Warning signs in a vague quote:
Ours is a written, itemized quote listing each opening, its method, its glass package and its finishing scope. Compare it line for line against the others you collect — that is the comparison that protects you. Background reading: brick-to-brick vs retrofit installation and contractor red flags we see in Ontario quotes.
Ontario Programs
There is no City of Toronto programme that replaces windows for free. What exists are provincial and utility energy-efficiency incentives that can offset part of a qualifying upgrade — currently the Home Renovation Savings™ program, delivered by Enbridge Gas and Save on Energy with support from the Government of Ontario.
What it covers, in outline. ENERGY STAR® certified windows and doors may qualify at a set amount per rough opening, and the pathway that includes windows requires a home energy assessment before work begins plus more than one qualifying upgrade — which is why homeowners often pair windows with attic insulation or air sealing. Amounts, eligibility rules and pathways are set by the program administrators, not by us. Our current summaries are on Ontario window and door grants and Ontario window rebates.
Programs change, so verify before you plan around one. Older incentives — the Canada Greener Homes Grant and the Enbridge Home Efficiency Rebate Plus among them — still appear in search results and in some contractors' sales material, but are no longer accepting new applications. Before committing to a project on the strength of a rebate, confirm the current program status, amounts and deadlines directly with the official program at homerenovationsavings.ca or with your utility. If a page or a salesperson quotes you a rebate without pointing to the administering program, treat it as unverified.
Where we fit, and where we do not. Trust Build is a windows, doors, masonry and insulation contractor. We are not the Government of Ontario, Enbridge Gas, Save on Energy, an energy auditor, or a program administrator, and we do not approve rebates or decide eligibility. What we do is install products that meet ENERGY STAR® certification, document the work and specifications you need for an application, and tell you which parts of your project appear to line up with the current program so you can check it yourself. Approval is always the program's decision, and homeowners are responsible for their own application and for confirming current terms. Rebates are also typically paid after completion and verification, so most homeowners budget the full project cost up front — see financing options.
Energy Efficiency
Every window we install is ENERGY STAR® certified for Ontario's climate zone, and performance is reported using the metrics Natural Resources Canada and ENERGY STAR Canada recognise — ER, U-value and SHGC. We give you those figures for the exact packages you are comparing instead of describing one as “better”.
Double vs. triple glazing. A double-pane unit has two panes and one insulating chamber; triple adds a third pane and a second chamber, improving insulation and sound control. Triple earns its cost most on exposed elevations, upper floors, and rooms facing arterial roads or transit — a real consideration on a lot of Toronto lots. On sheltered walls a well-built double-pane Low-E unit performs well. Deciding room by room usually beats committing the whole house either way. Detail on double vs. triple pane.
Low-E and argon. A Low-E coating reflects heat back to where you want it — in during winter, out during summer — and argon fill in the sealed chamber slows heat transfer compared with air. Both are available across our glazing packages.
Warm-edge spacer. The spacer holding the panes apart is where a lot of sealed units eventually fail. Super Spacer® is a warm-edge, no-metal spacer, which reduces conduction at the glass edge — the coldest part of the unit and where interior condensation typically shows first. More on our vinyl window construction page.
Orientation matters. A south-facing wall, a shaded north elevation and a large west-facing picture window do not want identical glass. Which coating and how many panes should follow the exposure, the room's use and the opening size — see glass options and performance. Replacing failing single-pane or older double-pane units noticeably cuts heat loss and drafts; we won't put a percentage on your bill, because that depends on your house, your heating system and how you use it. Ontario rebate programs may apply to qualifying upgrades — see Ontario window rebates.
Product Construction
For windows, Trust Build uses Roto lock and hardware systems — operators, hinges and multi-point locking. (Ferco multi-point locks are an entrance door product; they do not go into windows, and it is worth knowing the difference when you are comparing quotes.) Multi-point locking is what lets a casement sash pull tight to the frame at several points instead of relying on one latch.
The frames are insulated, foam-filled vinyl on our standard packages, with the sealed unit built around Low-E glass, argon fill and a Super Spacer® warm-edge spacer. Exterior and interior colours come from the Gentek palette — whites are standard, and the rest of the range is a factory-applied premium finish. See exterior and interior colours and interior trim and casing.
Where security is a specific concern — a ground-floor opening on a laneway, a rear elevation that isn't overlooked — a laminated impact glass upgrade bonds the panes with an interlayer so the glass can crack without opening a route through. It is compatible with Low-E, argon and Super Spacer®, so the thermal package does not change. See impact glass and security film.
Doors in Toronto
Windows are the bulk of our Toronto work, but doors run alongside them on most whole- home projects. Steel entry doors are the value choice and take a multi-point lock well; fiberglass entry doors hold a wood-grain stain finish and don't dent, which suits an exposed front entry. Downtown rowhouses often have narrow, non-standard openings, so entry doors are custom-sized rather than picked off a shelf, with sidelights or decorative glass where the entryway allows.
For the back of the house, sliding patio doors and French garden doors are the two common directions. Entrance doors use Ferco multi-point locking hardware — distinct from the Roto hardware in our windows. Full range on the doors hub, plus garage doors where the project includes them.

Choosing a Contractor
We are not going to tell you we are the best window company in Toronto — that is not a claim any contractor can substantiate about itself. What we can do is set out the attributes worth checking, and show where our own answers are documented so you can judge for yourself.
A company should be able to describe its process step by step, not just name a method. Ours is published: retrofit, brick-to-brick (full frame), hybrid / split-frame, and the overview of all three.
Vague product descriptions are hard to compare. Ours are specific: insulated foam-filled vinyl frames, Low-E glass with argon fill, Super Spacer® warm-edge spacers, Roto window hardware, Ferco entrance-door multi-point locks, Gentek exterior and interior colours. See vinyl window construction and glass options.
Ask for completed work in the housing type you own. Toronto examples with before-and-after photos: a stud-to-stud home-office casement rebuild, a bay window taken from white to black including skirt and head, a North York bow window replacement, a three-unit Scarborough casement renovation and an Etobicoke basement egress conversion. More finished work is in the project gallery.
Subcontracted crews are common in this trade. Our own crews handle the installation, including the masonry when the opening needs it, and we pull permits and coordinate inspections where a project requires them.
Homeowners researching Toronto window companies — including in Reddit threads and community groups — usually end up on third-party profiles, which is the right instinct. Trust Build's are published by organisations independent of us: a Better Business Bureau profile for the Concord location, a HomeStars profile with homeowner reviews of completed projects, and a Google Business Profile. All three are linked, claim by claim, from our company facts page, and customer feedback we publish ourselves is on reviews. We do not publish review counts or star ratings we cannot source, and we do not mark up our own review claims as third-party ratings. Our wider take on assessing reputation is in what to look for in an Ontario window company's reputation.
