Why you can trust EcoWatch
Although clean energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your home's efficiency can also have a big impact on home energy conservation. Drafty or leaky windows can cut your home's energy efficiency by up to 30%, according to the Department of Energy. In Ottawa, that's an average of $483 a year that you could save on your power bills by making the switch.
Thankfully, helping you save money with upgraded windows also aligns with our goals of conserving energy and the resources it takes to generate it.
Unlike other 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 Ottawa Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here's more information on how upgrading your windows could help you:
- Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of household energy use. Installing energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.
- Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if you have an older home.
Estimated Cost of Window Replacement in Ottawa
Windows come in different shapes and sizes, so costs and services will vary considerably. Here are the average costs and services that you can find from window installation companies.
How Much Do New Windows Cost?
On average, homeowners in Ottawa can anticipate that most window installations will range from $250 to $1,200, with the most common installations sitting at around $600. These amounts vary based on specific characteristics of your installation, such as material, type, number of windows, size, the location of your home and more.
It's important to keep in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save Ottawa homeowners $483+ a year when replacing single-pane windows.
Asking for free quotes from multiple installers is the best way to find out which one will work best for your budget.
What Services do Window Installers Offer?
In general, there are two kinds of window replacement services companies offer: full-frame and pocket installations.
Full-frame installations are usually done when you want to change the style of your windows or your window has a lot of rot or deterioration. With this service, your professionals will replace the full window, including the sill, frame and trim. A pocket installation entails replacing a window within the old frame. So, instead of removing the whole unit and reinstalling it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.
If you're still debating which type of installation you need, you can ask your installer and get their recommendation. The choice mostly depends on how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Ottawa
In our search to find the most reliable, eco-friendly window installers in Ottawa, EcoWatch chose the above companies as the best window installation companies in the city. We have evaluated the best window installers in Ottawa primarily based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows can cut your power 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 installation companies that serve the Ottawa area so you can find the right window installation company near you.
Work Quality
When selecting new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the type of window you get. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have positive things to say about their service from a certain company, it won't be featured on EcoWatch.
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
Protecting your investment in new windows is important. That's why window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Ottawa's climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Ottawa window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Ottawa, WI Window Replacement FAQs
How much should a window install cost?
The national average cost to replace a single window is about $600 but can range between $200 and $1,200, depending on several factors. The price is usually dependent on the location of your property, the type and material of the window and the size of the window. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
Which type of window is the best?
A window's energy efficiency depends on several factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.
Do you really need to use a window installation company?
Unless you have experience with home improvement projects and have the time to replace your own windows, we recommend hiring a professional installer. The process of installing windows is quite involved and can take anywhere from four to six hours for one window. Although it's tempting to try to save some money by doing it yourself, hiring a professional is a faster, more efficient and safer alternative.
When is the best time of year to replace windows?
Even though you can install windows any time of year, warmer weather is typically better for replacing windows. In addition, the weather should be dry, since rain can make the installation harder.
How often do you need to replace windows?
Windows generally last about 20 to 30 years, but anytime you notice damage on your windows, it's a good idea to have an expert take a look at them to see if they need any repairs or replacements.
