How Installing Energy-Efficient Windows in Ontario Saves You Money

By switching to energy-efficient windows, you and your family can take advantage of several benefits, such as:

  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which 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 lower your indirect greenhouse gas emissions by about 65 pounds per year after you switch to energy-efficient windows.
  • Save money on electricity bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% because you use less energy.

Estimated Cost of Window Replacement in Ontario

When looking into window installation, each company offers different services and prices. Let’s go over some average costs and services.

How Much Do New Windows Cost?

The national average cost to replace a single window is about $600 but can range from $200 to $1,200. How much it will cost is based on several factors, including number of windows, the location of your home, size, material, type and more.

With windows, efficiency is one of the most important factors for most homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — particularly during the winter — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Ontario homeowners $357+ per year after replacing single-pane windows.

Another factor that influences the total cost is the material you choose for your frame. Aluminum frames are typically the least expensive and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

The first step of a window replacement is to decide whether you want a full-frame or pocket installation.

Full-frame installations involve replacing the full window, including the sill, trim and frame. Full-frame installations are necessary when you want a new style or your window has considerable damage. These installations are more involved and will raise the overall cost. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and will be less expensive, but you can’t do this type of installment if you have any pre-existing rot or water damage.

If you’re not sure which kind of window installation service you need, your installer should be able to assist you. Generally, the decision is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Ontario

In our hunt to make your home improvements easier and more eco-friendly in Ontario, the EcoWatch Reviews team landed on the above companies as the top window installation companies in the city. We have reviewed the best window replacement companies in Ontario primarily based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows have been shown to lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since 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 the list because of the low odds that they would serve the average homeowner in Ontario.

Work Quality

When choosing new windows, the quality and range of services can often play just as important of a role in insulation and performance as the type of window 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

Customer feedback is another super important review factor. If the majority of customers don’t have positive things to say about their experience with a certain installer, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: as with most services, cheap window companies won’t always provide the highest quality service. On the other hand, we want to make sure we’re highlighting companies that offer a spectrum 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

Due to Ontario’s climate, homeowners will want to mitigate rot, low efficiency and water damage. 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 typical cost to install a single window can range between $450 and $650. There are several factors that affect how much it costs, such as how energy-efficient the windows are, styles and sizes of windows, the materials used in designing the windows, the number of windows, your property’s location and local labor costs.

What type of window is the most energy-efficient?

Generally, double-pane windows will be 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’ll get the most energy-efficient windows, look for models that have the blue Energy Star certification — they’re certified energy-efficient by the U.S. Department of Energy.

Can you replace your own windows?

If you’re handy and have the time and patience to do the job right, you may be able to install your own windows. However, if you don’t have the time or know-how, we recommend getting a professional to do it for you.

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. Additionally, the weather should be dry, because rain can make the installation harder.

How often do you need to 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.
