How Installing Energy-Efficient Windows in Ottawa Saves You Money
By switching to energy-efficient windows, you and your family can take advantage of several benefits, including:
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help raise the value of your property if you decide to sell.
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Ottawa, that's about 583 pounds per year on average.
- Save money on energy bills: Switching to energy-efficient windows reduces your energy bills by about 12% because you use less energy.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Ottawa
Windows come in different shapes, purposes and styles, so costs and services will differ tremendously depending on several factors. Below, we go over the average cost and services that you can get from window installation companies.
How Much Do New Windows Cost?
According to our market research, the typical cost of replacing a single window is about $600. However, window installation costs can range from $200 to $1,200 for each window. This is because window installations depend on a variety of factors specific to your home, such as the size, material and number of windows you need to replace, as well as where your property is located.
It's also worth keeping in mind that energy-efficient windows will usually cost more initially, but Energy Star predicts that upgrading the windows on your Ottawa home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you'll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
The cost of your window installation will also vary depending on the type of material you choose for the frames. Wood windows are typically the most expensive, although it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
The first thing to ask yourself when considering a window replacement is: Do you need a full-frame installation or a pocket installation?
A full-frame installation is a total window replacement. It involves removing the old window, the sill, and the exterior and interior trim. It can also involve extra materials, like insulation and drip edges, which raise the overall cost of the project. It's also worth noting that you may have to touch up the paint around the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are on the simpler end and won't carry as large a bill, but you can't do this kind of installment if you have any pre-existing rot or water damage.
If you're still trying to decide which kind of installation you should get, you can consult with your provider and get their recommendation. The decision mostly is influenced by how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Ottawa
In our hunt to make your home improvements easier and more eco-friendly in Ottawa, the EcoWatch Reviews team landed on the above companies as the best window installation companies in the city. We've decided to assess 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-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
This one is self-explanatory, but we've chosen to highlight window installers that serve Ottawa so you can find the best window installation company near you.
Work Quality
We're willing to bet that you're looking for a company to do a great job installing windows. We've vetted each installer featured on this list to ensure its contractors 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 customer feedback to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including cost, quality of installation, warranty, professionalism, quality of parts and more.
Cost
This one is a give-and-take: similar to most services, cheap window installation companies won't always provide the most quality service. Still, we want to ensure we're highlighting companies that offer a wide range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a sizable investment, so you'll want to make sure that investment is well protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to 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 the climate. If a company has less than 10 years of experience, it loses points in this category.
Ottawa, KS Window Replacement FAQs
What is the average cost to replace windows?
The national average cost to replace one window is about $600 but can range from $200 to $1,200, depending on several factors. The price is generally dependent on 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 upfront but can save you a decent amount of money a year in energy bills.
What kind 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 have the most energy-efficient windows, look for models with the blue Energy Star certification — that means they're certified energy-efficient by the U.S. Department of Energy.
Can I replace my own windows?
Even though you can install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Using a window replacement company can help guarantee that the installation is done properly and that you won't have to spend the time and effort to do it yourself.
When is the best time of year to replace windows?
Replacement windows can be installed during any season, but autumn might be best. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into the home, so the temperature outside doesn't necessarily matter that much. Most importantly, the weather should be dry.
When is it time to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to open or close, they may need to be replaced.
