How Installing Energy-Efficient Windows in Seattle Saves You Money

Energy-efficient windows can provide benefits in more than one way. Here are some reasons you may want to consider making the switch:

• Decrease your carbon footprint: By using less energy once you switch to energy-efficient windows, you’ll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.
• Save money on electricity bills: Once you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll need less energy to heat or cool your house.
• Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
• 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.

Estimated Cost of Window Replacement in Seattle

Let’s go over the cost of replacing your windows and the types of services you may need for your home.

How Much Do New Windows Cost?

Even though the national average cost to install one window is around $600, it can range from $200 to $1,200. How much it will cost varies based on several factors, like material, number of windows, size, type, the location of your home and more.

It’s also worth noting that energy-efficient windows will usually cost more initially, but Energy Star estimates that switching out the windows on your Seattle home can mean 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 upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Something else that affects the total cost is the material you select for your frame. Aluminum frames are typically the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

The first step when planning a window replacement is to figure out whether you need a full-frame or pocket installation.

A full-frame installation is a total window replacement. It involves removing the old window, the sill, and the exterior and interior trim. It also involves extra materials, such as insulation and drip edges, which increase the overall cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. A pocket installation means replacing a window without taking out the complete frame, which is generally cheaper than a full-frame installation.

If you’re unsure which kind of window installation service you should get, your installer can advise you. In general, the decision 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 Seattle

In our search to make your home improvements easier and more eco-friendly in Seattle, EcoWatch landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we evaluated each installer and assigned rankings using the following methodology:

Service Area

Since this is a guide for Seattle, we paid more attention to companies that provide services to the city. There are other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Seattle.

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 included on this list to ensure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends 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 nearly every category, including quality of installation, warranty, quality of parts, professionalism, cost and more.

Cost

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

Warranty

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

Years of Experience

Lastly, we like to see companies that have been in the industry for a while. 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.
