How Installing Energy-Efficient Windows in Kenmore Saves You Money
When you upgrade to energy-efficient windows, you may see some perks, such as:
- Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Upgrading to energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Decrease your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by about 65 pounds.
Estimated Cost of Window Replacement in Kenmore
Each window replacement company provides varying services and has different prices based on several factors.
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 per window. How much it will cost varies based on several factors, including material, type, number of windows, the location of your home, size 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 — especially during the winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Kenmore homeowners $368+ each year after replacing single-pane windows.
The cost of your window installation will also vary based on the kind of material you choose for the frames. Wood windows are generally the most expensive, though it depends on whether 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 planning a window installation is: Do you need a full-frame installation or a pocket installation?
A full-frame installation is a total window replacement. It involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves other materials, like insulation and drip edges, which increase the total 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. A pocket installation involves installing a new window within the old frame. So, instead of removing the whole window and reinstalling it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.
If you’re unsure which window installation service you should get, your installer should be able to advise you. Typically, the decision depends on factors like 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
EcoWatch reviews are different from most reviews, as we assess these companies through a sustainability lens. We’ve reviewed the best window installation companies in Kenmore mostly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows can reduce your energy 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 Kenmore so you can find a quality window installation company near you.
Work Quality
When it comes to new windows, the quality and range of services can often play just as important of a role in insulation and performance as the brand of window you choose. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another very important review factor. If the majority of customers don’t have positive feedback about their experience with 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 want 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
As discussed, windows are a significant investment, so you’ll want to make sure that investment is protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Kenmore’s climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of Kenmore window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
