Why you can trust EcoWatch
Although environmentally friendly energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your house's efficiency can also have a big impact on home energy conservation. The Department of Energy estimates that heat gained or lost through old or damaged windows could account for nearly 30% of heating and cooling use. In Washington, where the electric bills are an average of $29 per month, that's almost $$105 per year wasted.
Replacement windows improve your home's insulation, not only making you more comfortable during extreme temperatures, but also saving you some money and helping the environment.
Unlike other review sites, EcoWatch ranks window replacement companies based on energy efficiency while also considering cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Washington Saves You Money
When you upgrade to energy-efficient windows, you may see several benefits, including:
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
- Save money on power bills: Switching to energy-efficient windows lowers your energy bills by about 12% since you need less energy.
- Decrease your carbon footprint: In Washington, you can reduce your indirect greenhouse gas emissions by about 286 pounds per year after you switch to energy-efficient windows.
Estimated Cost of Window Replacement in Washington
Windows come in varying styles, shapes and purposes, so costs and services will differ remarkably depending on several factors. Below, we go over the average cost and services that you'll find from window installers.
How Much Do New Windows Cost?
Though the national average of replacing one window is around $600, it can range from $200 to $1,200. This is because the cost of window installations depend on several factors specific to your home, including the size, material and number of windows you need to install, as well as where your property is located.
Whether or not you opt for energy-efficient windows is another factor that will affect the cost. These will typically cost more than other windows, but on the other hand, you can save about $304 a year on your energy bills in Washington.
The cost of your window installation will also vary based on the kind of material you choose for the frames. Wood windows are usually the most expensive, though it depends if they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
The first question to ask yourself when planning on installing new windows is: Do you need a full-frame installation or a pocket installation?
Full-frame installations are usually recommended when you want a new style or your window has a lot of deterioration. With this service, your installers will replace the full window, including the frame, trim and sill. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and will be less expensive, but you can't do this type of installment if you have any pre-existing rot or water damage.
If you're unsure which window installation service you should get, your installer can advise you. In general, the choice is influenced by 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 Washington
EcoWatch reviews are different from most reviews, as we examine these companies through a sustainability lens. We've assessed the best window installation companies in Washington primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to 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 installation companies that serve a wide variety of states and cities so you can find the best window installation company near you.
Work Quality
We're certain that you're looking for a company to do a great job installing windows. We've vetted each installer in our guide to make sure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the highest rates of customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including professionalism, warranty, quality of installation, quality of parts, cost and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers' prices, we awarded 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. That's why window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Washington's climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of Washington window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Washington, PA Window Replacement FAQs
How much should a window install cost?
The average cost of replacing one window ranges from $450 to $650. There are many factors that affect how much it costs, such as styles and sizes of windows, your property's location, the number of windows, how energy-efficient the windows are, the materials used in designing the windows and local labor costs.
Which kind of window is the best?
Generally, double-pane windows are more efficient than single-pane windows and windows that don't open are more efficient than windows that do. To be sure you're getting the most energy-efficient windows, look for models with the blue Energy Star certification — this means they're certified energy-efficient by the U.S. Department of Energy.
When should I use a window installation company?
You should hire a window installation professional whenever you need to upgrade your windows. Installing windows is a complicated process that can be difficult to do on your own, so it's best handled by the professionals.
What time of year is the best time to replace my windows?
While you can install windows any time of year, warmer weather is typically better for installing replacement windows. In addition, it shouldn't be raining, as rain can make the installation more difficult.
Should I replace all my windows at once?
If your windows are more than 20 years old, you probably need to replace all of them. At that point, they are typically less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
