How Installing Energy-Efficient Windows in Westfield Saves You Money

Energy-efficient windows can offer benefits in several ways. Here are some reasons you may want to think about making the switch:

• Decrease your carbon footprint: By using less energy after upgrading to energy-efficient windows, you’ll also be reducing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Save money on power bills: Once you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll need less energy to heat or cool your home.
• Protect your investment: If your home is on the older side, your windows are most likely outdated.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.
• Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.

Estimated Cost of Window Replacement in Westfield

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

How Much Do New Windows Cost?

Even though the national average cost of installing one window is about $600, it can range from $200 to $1,200. How much it will cost depends on several factors, like size, type, the location of your home, material, number of windows and more.

It’s important to remember that windows with higher efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Westfield homeowners $457+ a year when replacing single-pane windows.

We advise getting free quotes from multiple window installers to find the one that works best for you.

What Services do Window Installers Offer?

In general, there are two types of window installation services companies offer: full-frame and pocket installations.

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 additional materials, including insulation and drip edges, which increase the overall cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are on the simpler end and won’t cost as much, as they involve simply replacing the window within its existing frame. But if the frame has any damage, you may have to get a full-frame installation instead.

If you’re not sure which window installation service you need, your installer can help you out. Typically, the decision is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.

Energy Star certified windows have been shown to cut your electricity 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 Westfield, we only included companies that serve the city. There are other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Westfield.

Work Quality

We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each installer included on this list to make sure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent online reviews to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across nearly every category, including quality of installation, cost, quality of parts, professionalism, warranty and more.

Cost

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

Warranty

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