Proudly Canadian, Toronto-Owned Since 1989.
Yes — every window and door we sell is manufactured right here in Toronto at our own production facility. We have been building Canadian-made products since 1989, which means our windows are specifically engineered for the temperature swings, humidity, and freeze-thaw cycles that Ontario homes face every year.
This matters because products made for milder climates often underperform in a GTA winter. When you buy from Delco, you are buying direct from the manufacturer — no middlemen, no imported products rebranded with a Canadian label.
Our windows are ENERGY STAR certified and built with a combination of features that work together to keep heat in during winter and out during summer:
Most older Toronto homes lose up to 40% of their heating energy through windows and doors. Our ENERGY STAR-rated products can reduce that loss significantly, which is reflected in lower gas and hydro bills year-round.
Double-pane windows have two layers of glass with an insulating gas fill between them. They are suitable for most GTA homes and are ENERGY STAR certified. They significantly outperform single-pane windows and are the most popular choice.
Triple-pane windows add a third layer of glass and a second gas-filled chamber. They are best suited for rooms with higher heat loss exposure — north-facing walls, corners, large picture windows, or rooms above unheated garages. They are also noticeably better for noise reduction, which is why they are popular on homes near busy roads or highways.
During your free in-home consultation, a Delco specialist will assess each window opening and recommend the right option for each location in your home — there's no need to apply the same solution to every window.
Our vinyl window frames are built to last 30 to 40 years under normal residential use. Vinyl does not rot, rust, peel, or require painting — it holds its colour and shape through decades of Ontario weather.
The sealed glass unit (the insulating glass between the panes) is warrantied against seal failure, which is the most common long-term issue with windows. All Delco windows and doors are backed by our lifetime transferable warranty, which covers both manufacturing defects and installation workmanship. That warranty transfers to the next owner if you sell your home — a genuine added value when listing.
Steel and fiberglass doors typically last 30+ years with minimal maintenance. Wood doors require periodic refinishing but can last the lifetime of the home when properly maintained.
Because we manufacture our own windows in Toronto, we can offer factory-direct pricing without the markup that third-party retailers add. As a general guide:
These are starting ranges — your final price depends on the specific products, your home's existing frame condition, and whether a retrofit or full-frame replacement is required. Every quote we provide is itemized, in writing, and guaranteed — the price you're quoted is the price you pay.
Yes. Ontario homeowners currently have access to rebates through the Home Renovation Savings Program (Save on Energy), which provides $100 per eligible window opening for ENERGY STAR certified windows, with a minimum of three windows required.
Toronto homeowners may also qualify for the City of Toronto Home Energy Loan Program (HELP), which offers financing for energy efficiency upgrades including window replacement, up to $125,000 at stated low interest rates — repaid through your property tax bill over time.
Note: the federal Canada Greener Homes Grant and Loan programs are both closed to new applications as of 2024–2025. Be cautious of any company still advertising those programs. Our team stays current on active programs and will walk you through what you qualify for at your free in-home consultation — no obligation required.
Yes. We offer flexible payment plans so you don't have to pay for everything upfront. Many homeowners choose to finance their project and offset the monthly payment with the energy savings on their utility bills — making the upgrade essentially cash-flow neutral.
Ask about our current financing options when you request your free quote. There is no pressure to commit, and getting your quote is completely free with no obligation. We'll lay out all your options clearly so you can make the right decision for your budget.
There are dozens of window companies in the GTA. Here is what makes Delco genuinely different:
Our warranty is a lifetime transferable warranty that covers:
Because we manufacture the product ourselves, we control the entire warranty process — you deal directly with Delco, not a third-party manufacturer in another province or country. If something is wrong, we fix it. No runaround, no cost.
The transferable aspect means if you sell your home, the warranty passes to the new owners — a benefit that very few competitors offer and that buyers genuinely notice during the purchase process.
For most homes, installation is completed in a single day. A typical order of 8 to 12 standard windows is usually done in 6 to 8 hours by our installation crew.
Larger projects — full-house replacements, bay or bow windows, custom-sized units — may require two days. Entry door replacements are typically 2 to 4 hours per door.
We give you a clear installation schedule before we begin and we protect your floors, furniture, and walls throughout. At the end of the day, our crew cleans up completely — you won't be left with dust, caulking tubes, or packaging. Most homeowners are genuinely surprised at how tidy the process is.
Yes — we install year-round, including in winter. Our crews are trained and equipped for cold-weather installation. The window opening is never exposed for more than a few minutes at a time during the swap, and we use cold-weather-rated caulking and insulating foam that performs correctly even in sub-zero temperatures.
In fact, booking in late fall or winter often means shorter wait times and better availability since it is our off-peak season. If you are planning a spring or summer project, many homeowners book their consultation in the winter to secure their spot and lock in their pricing.
Every window and door dealer may have different prices for their models and installation. Both product and installation costs can qualify. However, it is recommended that you shop around to find the best option for you. Depending on financing options, you may not have to come out of pocket for any of the costs.
In fact, there is a cost for not applying for the program. This program is already funded by government and utility charges. It can only be claimed if you apply.

Yes, rental homes can qualify as long as you are the owner.
Unfortunately, Tenants can’t qualify.
No, you can’t, as you must do the first assessment before you install the windows or doors.
Although a double-pane is more significantly insulative than a single pane window, you should be aware of the age of your windows. If your double-pane windows are older than 20 years, chances are, the seals have cracked, and there may be leakage. Also, old double-pane windows were made in an era before many of the advanced technologies like gas fillings, vinyl frames, and low-conductive spacers were readily available. Many of our homeowners replace old double-pane windows with new ones, and see significant energy savings.
A vinyl window is actually referring to the frame, not the glass itself. Glass panes remain “made of glass”. But the frame, the material along the edges that holds the window together, can be made of many kinds of material, including aluminum, vinyl (pvc), and wood. Vinyl has a low conductive property, which means that the temperature between outside and inside stay apart longer, and don’t pass through as easily as metal. For energy efficiency we refer to vinyl and fiberglass windows.
While our specialty is high-efficiency replacement vinyl windows, we do offer some other frame materials, including wood-aluminum hybrid frames, and newer aluminum framing, which has some of the energy efficient benefits of vinyl.
The loan can pay a portion (up to 15%) of the loan amount up front such as deposits and down payments. The remaining amount will be paid after the post-retrofit evaluation has verified the successful completion of the retrofits.
To request the upfront portion, you must upload your final contractor quote, and input the requested deposit amount, into your loan portal.
Retrofits can include qualified versions of:
These items must be of a certain rating and installed by a qualified contractor. Windows and Doors must be EnergyStar certified. More details can be found with Natural Resources Canada.
The grant provides funds that do not have to be repaid. This can be up to $10,600 per home, to cover both the evaluations and parts of the retrofits. Both the loan and grant require the same accountability program and work together. Pre and post-retrofit evaluations are required.
The loan, however, can be up to $40,000 in interest-free payments, paid over 10 years.
It’s simple. If you live in Ontario, you’ll be given access to a similar, but separate portal for the Canada Greener Homes Loan. For some provinces, it is directly part of the grant portal.
You must first have a qualified pre-retrofit evaluation performed before any retrofit work can start or be completed. Any retrofits already completed do not qualify, but additional retrofits recommended by the EnerGuide advisor from the evaluation can qualify.
No. First, you must apply for the grant and be qualified. Then you are eligible to apply for the loan. This allows the grant to be fully used and reduces the costs to the loan program.
