How Installing Energy-Efficient Windows in Markham Saves You Money
Energy-efficient windows can offer benefits in several ways. Here are a few reasons you may want to consider making the switch:
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: If you have a relatively old home, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
- Save money on power bills: After you install energy-efficient windows, you can expect a reduction in your bills by about 12% because you'll require less energy to heat or cool your home.
- Better temperature control in your home: When you reside in a city like Markham where the winters can be very cold, you often have to rely on your heater to keep your home warm. Energy-efficient windows can reduce how much heat is lost through your windows when heating your home.
Estimated Cost of Window Replacement in Markham
Each window replacement company provides varying services and has different prices depending on several factors.
How Much Do New Windows Cost?
Though the average to install one window is around $600, it can range from $200 to $1,200. But costs will differ significantly depending on the number of windows you need, the quality of your products, the current condition of your home and your location. Many window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. These extra services will increase overall project costs.
Keep in mind that energy-efficient windows may cost more upfront, but Energy Star estimates 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. These savings vary depending on your local climate, energy rates and individual home characteristics.
Requesting free quotes from several installers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
There are typically two kinds of window replacement services: full-frame and pocket installations.
Full-frame installations require replacing the entire window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has significant deterioration. Full-frame installations are more time-consuming and will increase overall costs. A pocket installation entails replacing a window within the existing frame, which is generally cheaper than a full-frame installation.
Your window installation company will be able to recommend the best type for your project. In Markham, the choice will mostly be influenced by how much damage there is currently and the age of your existing frames.

How We Choose the Best Window Installers in Markham
In our search to make your home improvements easier and more eco-friendly in Markham, the EcoWatch team evaluated dozens of companies before settling on these. We have decided to assess the top window replacement companies in Markham mostly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for Markham, we paid more attention to companies that cover the city. There are certainly other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Markham.
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 company featured on this list to ensure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don't have nice things to say about their service from a certain installer, you won't see it featured on EcoWatch.
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 scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Markham's climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Markham window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Markham, IL Window Replacement FAQs
How much should window installation cost?
The national average cost to install a single window is about $600 but can range between $200 and $1,200, based on a variety of factors. The price is generally influenced by the size of the window, the type and material of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What type of window is the best for energy efficiency?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you're getting the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.
Do you really need to use a window installation company?
You should hire a window installation professional whenever you want new windows. Installing windows is a complicated process that can be difficult and time-consuming, so it's best left to the professionals.
When is it time to replace your windows?
Windows typically have a lifespan of 20 to 30 years, but anytime you see damage on your windows, it's a good time to have them looked at by an expert to determine if they are in need of a repair or replacement.
