How Installing Energy-Efficient Windows in Washington Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here are more details about how upgrading your windows could benefit you:

• Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help increase the value of your home if you decide to sell.
• Save on energy bills: Switching to energy-efficient windows lowers your energy bills by about 12% because you use less energy.
• Reduce your carbon footprint: By using less energy once switching to energy-efficient windows, you’ll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Washington

Let’s take a look at the cost of window replacement and the types of services you may need for your home.

How Much Do New Windows Cost?

Although the typical cost to replace one window is around $600, it can range from $200 to $1,200. How much it will cost varies depending on several factors, like number of windows, the location of your home, type, material, size and more.

It’s also worth bearing in mind that energy-efficient windows will cost more initially, but Energy Star estimates that switching out the windows on your Washington home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you’ll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

Getting free quotes from several providers is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

In regard to window replacements, there are typically two kinds that your provider will offer: full-frame and pocket installations.

A full-frame installation replaces the total window, such as the sill, frame, trim and the window panes. Because this type of installation is more involved, it will be more expensive than a pocket installation. Pocket installations are on the simpler end and won’t carry as large a bill, as they involve simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you should opt for a full-frame installation instead.

Your window replacement company should be able to help you choose what’s best for your needs. In Washington, the decision will mostly depend on how old your home is and if there’s any damage. Wood can decay if it’s not maintained properly over the years, so it’s good to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Washington

EcoWatch reviews differ from most reviews because we look at these companies through a sustainability lens. Along with energy efficiency, we evaluated window companies all across the state and ranked them using the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the best window installation company near you.

Work Quality

When selecting new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand of window you opt for. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent customer feedback to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including quality of installation, warranty, cost, professionalism, quality of parts and more.

Cost

This one is a give-and-take: as with other services, cheap window installers won’t always provide the highest quality service. Still, we want to make sure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed, windows are a serious investment, so you’ll want to make sure that investment is protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
