How Installing Energy-Efficient Windows in Willistown Saves You Money

Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to consider making the switch:

  • Save money on electricity bills: Switching to energy-efficient windows lowers your energy bills by about 12% because you use less energy.
  • Protect your investment: When you have an older home, your windows could also be outdated or drafty.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 real estate value.
  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Willistown

Windows come in varying styles, purposes and shapes, so costs and services will differ tremendously based on your project. Below, we go over the average cost and services that you can get from window installers.

How Much Do New Windows Cost?

Although the typical to replace a single window is around $600, it can range from $200 to $1,200. How much it will cost you is based on several factors, including material, the location of your home, size, type, number of windows and more.

It's important to remember that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Willistown homeowners $310+ a year when replacing single-pane windows.

The cost of your window installation will also vary based on the kind of material you choose for the frames. Wood windows are usually the most expensive, although it depends if they are completely 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?

Generally, there are two types of window installation services you can get: full-frame and pocket installations.

A full-frame installation replaces the total window, such as the sill, frame, trim and the window panes. Because this kind of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations are simpler and won't cost as much because they involve merely replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.

If you're still debating which kind of installation to get, you can talk to your installer and get their advice. The decision mostly depends on how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Willistown

EcoWatch is different from other reviewers since we're examining these companies through a sustainability lens. We've decided to review the best window installation companies in Willistown mainly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Because this is a guide for Willistown, we only included companies that provide services to the city. There are certainly reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Willistown.

Work Quality

When installing new windows, the quality and range of services can often play just as important of a role in insulation and performance as the type of window you opt for. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent customer feedback to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including professionalism, quality of parts, warranty, cost, quality of installation and more.

Cost

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

Warranty

As discussed, windows are a considerable investment, so you'll want to be certain that investment is well protected. Window installation companies that provide 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 installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Also, bear in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.

Which type of window should I get?

When should I use a window installation company?

You should use a window installation professional whenever you need to upgrade your windows. Installing windows is a complex process that can be difficult and time-consuming, so it's best left to the professionals.

When is it time to replace your windows?

Windows usually last 20 to 30 years, but anytime you see damage on your windows, it's a good idea to have an expert take a look at them to see if they are in need of a repair or replacement.
