How Installing Energy-Efficient Windows in St Peters Saves You Money

Energy-efficient windows can offer benefits in more than one way. Here are a few reasons you may want to make the switch:

• Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
• Decrease your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 763 pounds.
• Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
• Save money on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Upgrading to energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in St Peters

Windows come in different styles, purposes and shapes, so costs and services will differ tremendously based on your project. Below, we detail the typical cost and services that you'll find from window installation companies.

How Much Do New Windows Cost?

According to our market research, the average cost of replacing a single window is about $600. However, window replacement costs can range from $200 to $1,200 a window. This is because of the fact that the cost of window installations are based on a variety of factors specific to your home, including the size, material and number of windows you need to replace, as well as where your property is located.

It's important to keep in mind that windows with the best efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save St Peters homeowners $382+ a year when replacing single-pane windows.

The cost of your window installation will also vary based on the type of material you choose for the frames. Wood windows are generally the most expensive, though it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

The first step of a window replacement is to think about whether you want a full-frame or pocket installation.

A full-frame installation is a replacement of the full window. It involves removing the old window, the sill, and the exterior and interior trim. It can also involve extra materials, including insulation and drip edges, which increase the overall cost of the project. Also worth noting: it's not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. A pocket installation involves installing a new window within the frame that's already there. This means instead of tearing out the whole window and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

If you're still trying to decide which kind of installation to get, you can consult with your provider and get their advice. The decision mostly is influenced by how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in St Peters

EcoWatch is different from other reviewers, as we examine these companies through a sustainability lens. Along with energy efficiency, we assessed each installer and ranked them using the following methodology:

Service Area

This one is self-explanatory, but we've chosen to highlight window installation companies that serve the St Peters area so you can find a quality window installation company near you.

Work Quality

When choosing new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the type of window you choose. 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 trends in recent online reviews to find the companies with the most consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including professionalism, quality of parts, quality of installation, cost, warranty and more.

Cost

This one is a give-and-take: as with other services, cheap window installers may not provide the most quality service. Still, we want to make sure we're highlighting companies that offer a wide range 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 offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a proven track record in the industry. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
