Why you can trust EcoWatch
Although eco-friendly energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your home’s efficiency can also have a large impact on home energy conservation. If you have traditional, outdated windows, your AC or heating system could be working overtime to heat or cool your house. This means spending more on energy bills.
That’s not great for either your bank account or the environment, but one of the top window installation companies can help you with that.
Unlike other sites, EcoWatch ranks window installation companies on energy efficiency while also taking into consideration cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Kenmore Saves You Money
By upgrading to energy-efficient windows, you can benefit in several ways, such as:
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
- Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Upgrading to energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
- Reduce your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by about 271 pounds.
- Protect your investment: Upgrading and repairing 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 Kenmore
Let’s go over the cost of installing new windows and the types of services you may need for your home.
How Much Do New Windows Cost?
According to our research, the national average cost to install a single window is around $600. However, window replacement costs can range from $200 to $1,200 for each window. How much it will cost depends on several factors, including size, material, type, number of windows, the location of your home and more.
With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — particularly during the winter — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Kenmore homeowners $366+ each year after replacing single-pane windows.
We advise requesting free quotes from several window companies to find the one that works best for your budget.
What Services do Window Installers Offer?
The first question to ask yourself when planning to replace your windows is: Should you get a full-frame installation or a pocket installation?
A full-frame installation replaces the total window, including the sill, frame, trim and the window panes. Because this type of installation requires more time and labor, it will be more expensive than a pocket 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 cost as much, but you can’t do this kind of installment if you have any pre-existing rot or water damage.
If you’re unsure which kind of window installation service you should get, your installer can advise you. In general, the choice is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Kenmore
In our search to find the most reliable, eco-friendly window installers in Kenmore, the EcoWatch Reviews team landed on the above companies as the top window installation companies in the city. We’ve decided to assess the best window installation companies in Kenmore mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Because this is a guide for Kenmore, we paid more attention to companies that provide services to the city. There are other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Kenmore.
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 installer in our guide to ensure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If most customers don’t have positive feedback about their experience with a certain company, you won’t see it featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window installers may not provide the highest quality service. Still, we want to make sure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed, windows are a significant investment, so you’ll want to be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a proven track record in the industry. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Kenmore, WA Window Replacement FAQs
How much does window installation cost?
The national average cost of installing a single window is around $600 but can range from $200 to $1,200, depending on a few different factors. The price is usually dependent on the type and material of the window, the size 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.
Which type of window should I get?
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. To be sure you’ll get the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — this means they’re certified energy-efficient by the U.S. Department of Energy.
What services do window replacement companies do?
Window installation professionals will do the entire process — from replacing old windows with brand-new ones to cleaning up afterward. In addition, some companies offer window manufacturing, customization and repairs.
When is it time to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may need to be replaced.
How long does it usually take to install windows?
Since the average installation time is 30 minutes per window, about 16 windows can be installed during a typical 8-hour work day.
