How Installing Energy-Efficient Windows in Ontario Saves You Money

Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here are more ways upgrading your windows could benefit you:

  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Protect your investment: If you have an older home, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help increase the value of your property if you decide to sell.
  • Reduce your carbon footprint: In Ontario, you can reduce your indirect greenhouse gas emissions by about 65 pounds per year when you switch to energy-efficient windows.
  • Save on energy bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of residential energy use. Switching to energy-efficient windows can help decrease that number, which helps you save $357 a year on your bills.

Estimated Cost of Window Replacement in Ontario

Let’s go over the cost of installing new windows and the types of services offered by installers.

How Much Do New Windows Cost?

On average, Ontario homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at about $600. Costs will vary considerably depending on the current condition of your home, the quality of your products, the number of windows you need and your location. A lot of window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. Additional services will increase your overall project costs.

Keep in mind that energy-efficient windows may have a higher price, but Energy Star predicts the upgrade will save you between $101 and $583 a year when installing single-pane windows and between $27 and $197 per year when you install double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.

Getting free quotes from several providers is the best way to find out which one will work best for your budget.

What Services do Window Installers Offer?

The first step when planning a window replacement is to think about whether you need a full-frame or pocket installation.

A full-frame installation replaces the full window, including the sill, frame, trim and the window panes. Because this type of installation is more involved, it will cost more than a pocket installation. Pocket installations are simpler and won’t carry as large a bill, as they entail merely replacing the window within its existing frame. But if the frame has any damage, you should opt for a full-frame installation instead.

If you’re still trying to decide which type of installation to get, you can talk to your installer and get their advice. The choice mostly is influenced by how old the frames are and if there’s any damage present.

How We Choose the Best Window Installers in Ontario

The EcoWatch Reviews team is different from most reviewers because we assess these companies through a sustainability lens. We’ve assessed the best window installers in Ontario mostly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows have been shown to cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve Ontario so you can find a quality window installation company near you.

Work Quality

When installing new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the brand you opt for. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent customer feedback to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across nearly every category, including cost, warranty, quality of installation, quality of parts, professionalism and more.

Cost

This one is a give-and-take: similar to other services, cheap window companies may not provide the highest quality service. Still, 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 to many homeowners. For that reason, window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of Ontario’s climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Ontario window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

Ontario, NY Window Replacement FAQs

How much does window installation cost?

The average cost of installing a single window ranges from $450 to $650. There are several factors that influence the cost, such as local labor costs, styles and sizes of windows, the number of windows, how energy-efficient the windows are, your property’s location and the materials used in designing the windows.

Which kind of window is the best?

Generally, double-pane windows are more efficient than single-pane windows and windows that don’t open are more efficient than windows that do. If you want to be sure you’re getting the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — they’re certified energy-efficient by the U.S. Department of Energy.

Can I replace my own windows?

While it is possible to install your own windows, doing so requires a lot of time and experience with home improvement projects. Hiring a professional can help ensure that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.

When is the best time of year to replace windows?

Replacement windows can be installed at any time, but autumn might be the best season. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into your home, so the temperature outside isn’t necessarily a big factor. What’s more important than the temperature is that the weather should be dry.

How often should you replace your windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may be in need of replacement.
