How Installing Energy-Efficient Windows in Spokane Saves You Money

Energy-efficient windows can benefit you in more than one way. Here are a few reasons you may want to think about making the switch:

• Decrease your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Spokane, that’s about 271 pounds per year on average.
• Save money on power bills: After you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll use less energy to heat or cool your house.
• Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
• Protect your investment: When you have an older home, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its value.

Estimated Cost of Window Replacement in Spokane

Let’s take a look at the cost of replacing your windows and the types of services offered by installers.

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 for each window. How much it will cost depends on several factors, like material, the location of your home, number of windows, type, size and more.

It’s also worth keeping in mind that energy-efficient windows will usually cost more initially, but Energy Star estimates that upgrading the windows on your Spokane home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each 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.

The cost of your window installation will also vary depending on the type of material you choose for the frames. Wood windows are typically the most expensive, but it depends on whether they are solid 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?

There are typically two types of window replacement services: full-frame and pocket installations.

A full-frame installation is a total window replacement. This service involves taking out the old window, the sill, and the exterior and interior trim. It can also involve extra materials, such as 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 entails replacing a window within the existing frame, which is generally less expensive than a full-frame installation.

Your window installer should be able to help you choose which type of installation you should get.

How We Choose the Best Window Installers in Spokane

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

Service Area

Since this is a guide for Spokane, we gave more points to companies that serve the city. There are certainly reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Spokane.

Work Quality

When choosing new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand of window you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another very important review factor. If the majority of customers don’t have good feedback about their experience with a certain company, it won’t be featured on EcoWatch.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important. That’s why window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of Spokane’s climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Spokane window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
