Why you can trust EcoWatch
A review of the top window installation companies in Ontario may not seem like the most riveting article on EcoWatch, but trust us, windows have a more direct impact on your life than you might realize. The Department of Energy estimates that heat gained or lost through traditional or outdated windows could be responsible for around 30% of residential energy climate use. In Ontario, where the electric bills are an average of $39 per month, that's almost $$140 per year wasted.
That's also bad news for the environment because the extra energy required by leaky windows increases your carbon footprint.
Unlike other review sites, EcoWatch ranks window companies on energy efficiency while also taking into consideration cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Ontario Saves You Money
Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to think about making the switch:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.
- Reduce your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Ontario, that's about 525 pounds per year on average.
- Save money on power bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Installing energy-efficient models can help lower how much energy is used in your home, therefore saving you about 12% more on your bills.
Estimated Cost of Window Replacement in Ontario
Windows come in various purposes, shapes and styles, so costs and services will vary remarkably based on several factors. Below, we describe the average cost and services that you'll find from window replacement companies.
How Much Do New Windows Cost?
On average, Ontario homeowners can expect their window installations to range from $250 to $1,200. The average cost is at approximately $600. But costs will vary significantly depending on the current condition of your home, the number of windows you need, your location and the quality of your products. A lot of window companies also offer replacement door installations and other add-ons like coating, shutters, baths and more. Additional services will increase your overall project costs.
With windows, efficiency is one of the most important factors for many homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Ontario homeowners $290+ a year after replacing single-pane windows.
Costs will also vary depending on the material of your frame. Aluminum frames have the lowest price. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
There are generally two types of window replacement services: full-frame and pocket installations.
Full-frame installations involve replacing the full window, including the sill, frame and trim. Full-frame installations are necessary when you want a new style or your window has noticeable deterioration. Because full-frame installations are more involved, they will increase overall costs. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
Your window replacement company should be able to help you figure out what's best for your needs. In Ontario, the decision will mostly depend on how old your home is and if there's any damage. Wood can decay if it's not maintained properly over the years, so it's a good idea to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Ontario
EcoWatch differs from most reviewers because we examine these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and ranked them using the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve the Ontario area so you can find a quality window installation company near you.
Work Quality
When picking new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the brand of window you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including professionalism, warranty, quality of installation, cost, quality of parts and more.
Cost
This one is a give-and-take: similar to most services, cheap window installation companies won't always provide the most quality service. On the other hand, we want to make sure we're highlighting companies that provide a wide range of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. That's why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a proven track record in the industry. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Ontario, OH Window Replacement FAQs
How much should a window install cost?
The average cost of installing a single window ranges between $450 and $650. There are a variety of factors that influence the cost, which include styles and sizes of windows, the materials used in designing the windows, the number of windows, local labor costs, your property's location and how energy-efficient the windows are.
What kind of window is the best for energy efficiency?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want to be sure you'll have the most energy-efficient windows, look for models with the blue Energy Star certification — they're certified energy-efficient by the U.S. Department of Energy.
Do you really have to use a window installation company?
You should use a window installation professional whenever you want to upgrade your windows. Installing windows is a involved process that can be difficult and time-consuming, so it's best left to the professionals.
When is the best time of year to replace windows?
Even though you can install windows any time of year, warmer weather is often better for installing replacement windows. In addition, it shouldn't be raining, as rain can make the installation more difficult.
Should I replace all my windows at the same time?
If you're upgrading your windows to save on your energy bills, replacing all the windows together is the only way to see a noticeable difference. On the other hand, if you have only one or two windows that are broken or drafty, you can replace just those.
