Why you can trust EcoWatch
A guide on the best window replacement companies in Oakville 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 think. Damaged or outdated windows can cost you in electric bills. In fact, the Department of Energy estimates that about 30% of your home's heat or cool air could be lost through your windows.
That's also bad news for the environment because the additional energy used by drafty windows increases your carbon footprint.
As windows have such a big impact on your home, selecting the right company for you is a big decision to make. That's why the EcoWatch team has created this list of the best window installation companies, so you can make an informed decision more easily.

How Installing Energy-Efficient Windows in Oakville Saves You Money
Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to think about making the switch:
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
- Save money on power bills: Since energy-efficient windows reduce the amount of energy needed to heat or cool your home, they can help you save around $376 annually on your energy bills in Oakville.
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Oakville, that's about 763 pounds per year on average.
Estimated Cost of Window Replacement in Oakville
Windows come in different shapes and sizes, so costs and services will differ remarkably. Here are the average costs and the primary services that you'll find from the average window installation company.
How Much Do New Windows Cost?
Even though the average of replacing a single window is about $600, it can range anywhere from $200 to $1,200. But prices differ remarkably 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 replacements, which will make your project cost more.
Keep in mind that energy-efficient windows may come at a higher price tag, but Energy Star predicts the upgrade will save you between $101 and $583 a year when installing single-pane windows and between $27 and $197 a year when installing double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.
Costs will also vary based on the material you choose for your window frames. Aluminum frames cost the least. They're sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made using 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?
In general, there are two types of window replacement services companies offer: 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 raise the total cost of the project. Also worth noting: it's not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. A pocket installation involves replacing a window within the existing frame, which is usually cheaper than a full-frame installation.
Your window installation company should be able to help you decide which type of installation you should get.

How We Choose the Best Window Installers in Oakville
EcoWatch reviews differ from other reviews since we look at these companies through a sustainability lens. We have assessed the best window installers in Oakville mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve the Oakville area so you can find the best window installation company near you.
Work Quality
When it comes to new windows, the quality and variety 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 more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to find the companies with the highest rates of 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 parts, warranty, quality of installation, professionalism and more.
Cost
Cheaper windows don't necessarily 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 points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a considerable investment, so you'll want to make sure that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Oakville's climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Oakville window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
