Why you can trust EcoWatch
A guide on the top window installation companies in Ottawa may not seem like the most compelling article on the EcoWatch site, but trust us, windows have a more direct impact on your life than you might realize. The Department of Energy estimates that heat gained or lost through traditional or outdated windows could represent close to 30% of heating and cooling costs. In Ottawa, where the electric bills are an average of $55 per month, that’s almost $$196 per year wasted.
That’s not great for your wallet or the environment, but one of the top window installation companies can help with that.
Unlike other review sites, EcoWatch ranks window replacement companies based on energy efficiency while also considering cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Ottawa Saves You Money
By switching to energy-efficient windows, you can benefit in several ways, including:
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Decrease your carbon footprint: In Ottawa, you can lower your indirect greenhouse gas emissions by about 583 pounds per year when you install energy-efficient windows.
- Save money on power bills: Switching to energy-efficient windows reduces your energy bills by about 12% since you use less energy.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if your home is on the older side.
Estimated Cost of Window Replacement in Ottawa
Let’s take a look at the cost of window installation and the types of services offered by installers.
How Much Do New Windows Cost?
Typically, Ottawa homeowners can anticipate their replacement window installations to range from $250 to $1,200. The average cost sits at approximately $600. But prices differ considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door installations, which carry a higher price tag.
Whether or not you want energy-efficient windows is another factor that will affect the cost. These will typically cost more than other windows, but on the other hand, you can save about $463 a year on your energy bills in Ottawa.
Costs will also vary based on the material you pick for your window frames. Aluminum frames have the lowest price. They’re sturdy, light and easy to maintain, but offer 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 offer decent insulation for your home.
What Services do Window Installers Offer?
There are generally two types of window installation services: full-frame and pocket installations.
Full-frame installations entail replacing the complete window, including the trim, sill and frame. Full-frame installations are necessary when you want a new style or your window has considerable rot. Because these installations are more involved, they will raise overall costs. Pocket installations are simpler and won’t carry as large a bill, as they entail simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you may have to get a full-frame installation instead.
Your window installation company should be able to help you figure out which type of installation you need.

How We Choose the Best Window Installers in Ottawa
EcoWatch differs from most reviewers because we examine these companies through a sustainability lens. We have decided to review the top window replacement companies in Ottawa mainly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the right window installation company near you.
Work Quality
We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company in our guide to make sure its technicians are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent online reviews to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including quality of installation, cost, professionalism, quality of parts, warranty and more.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed previously, windows are a sizable investment, so you’ll want to be certain that investment is protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Ottawa’s climate, homeowners will want to mitigate low efficiency, rot 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, KS Window Replacement FAQs
How much does a window install cost?
The typical cost to install a window can range between $450 and $650. There are several factors that affect the price, including styles and sizes of windows, the number of windows, your property’s location, how energy-efficient the windows are, the materials used in designing the windows and local labor costs.
Which type of window should I get?
A window’s energy efficiency is affected by a variety of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified 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 install their own windows. The installer will also clean up after the installation is done.
When is the best time of year to replace windows?
Replacement windows can be installed any time of the year, but warmer weather is typically better. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into the home, so the temperature outside isn’t necessarily a big factor. What’s most important is that the weather should be dry.
How long does it usually take to install windows?
Since the average installation time of a window is 30 minutes, about 16 windows can be installed during a typical 8-hour work day.
