How Installing Energy-Efficient Windows in Washington Saves You Money

Upgrading to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here's more information on how upgrading your windows could help you:

• Protect your investment: If you have an older home, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help raise the value of your property if you decide to sell.
• Save on energy bills: Once you install energy-efficient windows, you can see a reduction in your bills by about 12% since you’ll need less energy to heat or cool your house.
• Reduce your carbon footprint: In Washington, you can lower your indirect greenhouse gas emissions by about 642 pounds per year after you install energy-efficient windows.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Washington

When considering window installation, each company offers varying services and prices. Let’s go over some typical costs and services.

How Much Do New Windows Cost?

On average, homeowners in Washington can anticipate that most replacement window installations will range from $250 to $1,200, with the average cost at about $600. But costs vary considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations and replacements, which will add extra costs to your project.

It’s also worth noting that energy-efficient windows will usually cost more upfront, but Energy Star estimates that switching out the windows on your Washington home translates to an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you’ll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

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?

The first step when considering a window installation is to clarify whether you want a full-frame or pocket installation.

Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has significant rot or deterioration. Full-frame installations require more time and labor and will increase overall costs. A pocket installation entails replacing a window within the existing frame, which tends to be cheaper than a full-frame installation.

Your window installation company can recommend the best type for your project. In Washington, the decision will mostly be based on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Washington

In our hunt to make your home improvements easier and more eco-friendly in Washington, the EcoWatch team landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we reviewed each installer and ranked them based on the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve Washington so you can find the best window installation company near you.

Work Quality

We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each company on this list to ensure its contractors are well-qualified and that the company has received tons 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 service from a certain installer, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: similar to most services, cheap window companies are not going to provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that provide a range of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed previously, windows are a significant investment, so you’ll want to be certain that investment is protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of 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.
