How Installing Energy-Efficient Windows in West Chester Saves You Money

By switching to energy-efficient windows, you can take advantage of several benefits, including:

• Protect your investment: If you have an older home, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.
• Reduce your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by 286 pounds per year on average.
• Save money on electricity bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of household energy use. Switching to energy-efficient windows can help reduce that amount, which helps you save some money on your bills.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.

Estimated Cost of Window Replacement in West Chester

Windows come in varying shapes and sizes, so costs and services will differ considerably. Here are the average costs and the primary services that you’ll find from window installers.

How Much Do New Windows Cost?

According to our research, the national average cost to replace a single window is about $600. However, window replacement costs can range from $200 to $1,200 for each window. This is because of the fact that the cost of window installations are based on several factors specific to your home, like the size, material and number of windows you need to install, as well as the location of your property.

Bear in mind that energy-efficient windows may come at a higher price tag, but Energy Star predicts the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 a year when installing double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.

Something else that influences the total cost is the material you select for your frame. Aluminum frames are usually the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

There are generally two types of window installation services: full-frame and pocket installations.

Full-frame installations entail replacing the complete window, including the trim, frame and sill. You most likely need a full-frame installation when you want a new style or your window has considerable rot or deterioration. Because these installations are more involved, they will raise the overall cost. A pocket installation involves installing a new window within the frame that’s already there. This means instead of removing the whole window and rebuilding it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

If you’re still debating which kind of installation you need, you can consult with your installer and get their advice. The choice mostly depends on the age of your window frames and if there’s any damage present.

In our search to make your home improvements easier and more eco-friendly in West Chester, the EcoWatch Reviews team chose the above companies as the top window installation companies in the city. Along with energy efficiency, we reviewed several window installers in West Chester and ranked them using the following methodology:

Service Area

Because this is a guide for West Chester, we paid more attention to companies that provide services to the city. There are certainly reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in West Chester.

Work Quality

When selecting new windows, the quality and range of services often plays just as important of a role in insulation 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

We analyzed trends in recent online reviews to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including professionalism, quality of installation, quality of parts, cost, warranty and more.

Cost

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

Warranty

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

Years of Experience

Lastly, we like to see companies that have a proven track record in the industry. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
