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.

Whether you're updating for aesthetics or have windows that need repairs, windows play a vital role in conserving energy in your home. Drafty or leaky windows can lower your home's energy efficiency by up to 30%, according to the Department of Energy. In Ottawa, that's around $308 per year that you could save on your electricity bills by making the switch.

That's also bad news for the environment, as the additional energy required by leaky windows increases your carbon footprint.

Efficient windows are of particular importance in Ottawa, where the temperature varies throughout the year. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $308 a year.

How Installing Energy-Efficient Windows in Ottawa Saves You Money

By upgrading to energy-efficient windows, you can enjoy several benefits, such as:

  • Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can lower your carbon footprint by about 12%, according to Energy Star.
  • Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out damaging UV rays.
  • Save on electricity bills: After you switch to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll require less energy to heat or cool your house.
  • Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.

Estimated Cost of Window Replacement in Ottawa

Each window installation company offers various services and has varying prices based on several factors.

How Much Do New Windows Cost?

The average cost to replace one window is about $600 but can range from $200 to $1,200. These estimates vary based on the specifics of your installation, like the location of your home, size, number of windows, type, material and more.

Bear in mind that energy-efficient windows may cost more, but Energy Star predicts the upgrade will save you between $101 and $583 per year when you install single-pane windows and between $27 and $197 per year when you install double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.

Costs will also vary based on the material of your frame. Aluminum frames have the lowest price. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made with wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

Generally, there are two kinds of window installation services you can get: full-frame and pocket installations.

A full-frame installation is a replacement of the total window. It involves removing the old window, the sill, and the exterior and interior trim. It also involves other materials, including insulation and drip edges, which increase the overall cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are simpler and won't carry as large a bill, as they involve simply replacing the window within its existing frame. But if the frame has any damage, you should opt for a full-frame installation instead.

Your window installer should be able to help you figure out which type of installation you need.

How We Choose the Best Window Installers in Ottawa

In our search to find the most reliable, eco-friendly window installers in Ottawa, the EcoWatch Reviews team examined dozens of companies before settling on these. We've evaluated the top window replacement companies in Ottawa primarily based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Because this is a guide for Ottawa, we only included companies that cover the city. There are certainly reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Ottawa.

Work Quality

When it comes to new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand of window you opt for. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another very important review factor. If the majority of customers don't have nice feedback about their experience with a certain window installation company, it won't be featured on EcoWatch.

Cost

This one is a give-and-take: as with other services, cheap window installation companies are not going to provide the most quality service. Still, we want to ensure we're highlighting companies that provide a wide range of price and financing options so they're accessible to most homeowners.

Warranty

As discussed previously, windows are a serious investment, so you'll want to make sure that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have been in the industry for a while. 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.

Ottawa, IL Window Replacement FAQs

What is the typical cost to install new windows?

The average cost of installing a window can range between $450 and $650. There are several factors that affect the cost, including your property's location, how energy-efficient the windows are, the materials used in designing the windows, styles and sizes of windows, local labor costs and the number of windows.

What are the most common types of replacement windows?

The most common types of windows for homes are casement windows, double-hung and single-hung windows, bay windows, transom windows, slider windows, awning windows and picture windows.

Can you install your own windows?

Even though it is possible to install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Hiring a professional can help ensure that the installation is done properly and that you won't have to spend the time and effort to do it yourself.
