How Installing Energy-Efficient Windows in Stafford Saves You Money

When you upgrade to energy-efficient windows, you may see some benefits, such as:

• Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.
• Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Switching to energy-efficient models can help decrease how much you have to pay, therefore saving you about 12% more on your bills.
• Reduce your carbon footprint: In Stafford, you can lower your indirect greenhouse gas emissions by about 147 pounds per year once you switch to energy-efficient windows.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Stafford

Windows come in different shapes and sizes, so costs and services will differ considerably. 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?

According to our market research, the typical cost to install a single window is about $600. However, window installation costs can range from $200 to $1,200 for each window. How much it will cost is based on several factors, including the location of your home, size, type, number of windows, material and more.

It’s also worth noting that energy-efficient windows will cost more upfront, but Energy Star predicts that switching out the windows on your Stafford home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you’ll save by switching 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 find out which one will work best for your budget.

What Services do Window Installers Offer?

When considering window installations, there are typically two kinds that your provider will have: full-frame and pocket installations.

A full-frame installation is a total window replacement. This service involves removing the old window, the windowsill, and the exterior and interior trim. It also involves extra materials, such as insulation and drip edges, which increase the total 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 entails installing a new window without replacing the frame. So, instead of removing the whole window and reinstalling it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.

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 Stafford

EcoWatch is different from most reviewers because we examine these companies through a sustainability lens. We’ve reviewed the top window installation companies in Stafford primarily based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows have been shown to lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Because this is a guide for Stafford, we paid more attention to companies that serve the city. There are certainly other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Stafford.

Work Quality

When picking 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 give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent customer feedback to find the companies with the most consistent customer satisfaction. Customer satisfaction might be the most important factor, as it indicates the quality of services across nearly every category, including professionalism, warranty, cost, quality of installation, quality of parts and more.

Cost

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

Warranty

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

Years of Experience

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