How Installing Energy-Efficient Windows in Fort Lewis Saves You Money

There are several perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch include the following:

• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
• Save on electricity bills: Because energy-efficient windows lower the amount of energy used to heat or cool your home, the switch can help you save about $409 annually on your energy bills in Fort Lewis.
• Decrease your carbon footprint: In Fort Lewis, you can reduce your indirect greenhouse gas emissions by about 271 pounds per year once you install energy-efficient windows.
• Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help raise the value of your property if you decide to sell.

Estimated Cost of Window Replacement in Fort Lewis

Windows come in different shapes and sizes, so costs and services will differ remarkably. Here are the typical costs and the primary services that you can find from the average window installation company.

How Much Do New Windows Cost?

On average, homeowners in Fort Lewis can anticipate that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. But costs will vary considerably based on the current condition of your home, the number of windows you need, the quality of your products and your location. Many window companies also offer replacement door installations and other add-ons like baths, shutters, coating and more. These extra services will increase your overall project costs.

With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more initially, but by increasing the efficiency of your home — particularly during the winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Fort Lewis homeowners $409+ each year after replacing single-pane windows.

Asking for free quotes from several installers is the best way to figure out which one will work best for your budget.

What Services do Window Installers Offer?

When it comes to window installations, there are typically two types that your installer will offer: full-frame and pocket installations.

A full-frame installation replaces the entire window, including the sill, frame, trim and the window panes. Because this type of installation is more involved, it will cost more than a pocket installation. A pocket installation involves installing a new window within the frame that’s already there. So, instead of tearing out the whole unit and reinstalling it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.

If you’re unsure which kind of window installation service you should get, your installer should be able to assist you. Typically, the choice depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Fort Lewis

In our hunt to find the most reliable, eco-friendly window installers in Fort Lewis, the EcoWatch Reviews team assessed dozens of companies before deciding on these. We’ve reviewed the top window installation companies in Fort Lewis mainly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for Fort Lewis, we gave more points to companies that provide services to the city. There are certainly other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Fort Lewis.

Work Quality

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

Customer Reviews

Customer feedback is another super important review factor. If the majority of customers don’t have positive things to say about their service from a certain window installation company, it won’t be featured on EcoWatch.

Cost

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

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Due to Fort Lewis’s climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Fort Lewis window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
