Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Although renewable energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your home's energy efficiency can also have a considerable impact on home energy conservation. If your house has old or damaged windows, your HVAC system could be working extra hard to heat or cool your house. This means spending more on energy bills.

Installing efficient windows on your property can help you save money every month on your electricity bills — and you can help the environment, too.

Efficient windows are particularly important in Ontario, where winters are long and cold. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $357 a year.

How Installing Energy-Efficient Windows in Ontario Saves You Money

There are quite a few benefits of upgrading to energy-efficient windows. A few reasons you may want to consider making the change are the following:

  • Better temperature control in your home: Living in a warm place like Ontario often means needing your AC to keep your house cool. Energy-efficient windows can lower how much cool air is lost through your windows when cooling your home.
  • Better temperature control in your home: When you live in a place like Ontario where the winters can get cold, you usually have to depend on your heater to keep your home warm. Energy-efficient windows can cut back on the amount of heat lost through your windows when heating your home.
  • Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its value.
  • Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Ontario, that's about 65 pounds per year on average.

Estimated Cost of Window Replacement in Ontario

When considering window installation, each company offers varying services and costs. Let's go over some average costs and services.

How Much Do New Windows Cost?

Typically, Ontario homeowners can anticipate their replacement window installations to range from $250 to $1,200. The average cost sits at around $600. This is because the cost of window installations depend on a variety of factors specific to your home, such as the size, material and number of windows you need to install, as well as where your property is located.

Whether or not you want to install energy-efficient windows is another factor that will affect the cost. These will usually cost more than other windows, but on the other hand, you can save about $357 a year on your energy bills in Ontario.

Costs will also vary based on the material you choose for your window frames. Aluminum frames are the least expensive. 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 cost the most 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 typically two types of window replacement services: full-frame and pocket installations.

Full-frame installations are usually recommended when you want a new style or your window has a lot of rot or deterioration. With this service, your professionals will replace the entire window, including the trim, frame and sill. Pocket installations (or retrofits) involve replacing a window within the 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 installer should be able to help you choose which type of installation you should get.

How We Choose the Best Window Installers in Ontario

EcoWatch reviews differ from most reviews since we assess these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and ranked them based on the following methodology:

Service Area

Because this is a guide for Ontario, we gave more points to companies that cover the city. There are other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Ontario.

Work Quality

When picking new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the brand you choose. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends 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 reflects the quality of services across most other categories, including quality of parts, quality of installation, professionalism, warranty, cost and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed, windows are a considerable investment, so you'll want to be certain that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a good track record in the industry. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Ontario, NY Window Replacement FAQs

What is the average cost to install windows?

The national average cost to install one window is around $600 but can range between $200 and $1,200, based on a few different factors. The price is typically influenced by the location of your property, the size of the window and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.

Which kind of window should I get?

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. To be sure you'll have the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — they're certified energy-efficient by the U.S. Department of Energy.

What services do window installation companies provide?

Window installers visit your house to remove your old windows and replace them with new ones. Some providers install products made by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is finished.

How often should you replace windows?

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