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

When you switch to energy-efficient windows, you may see some benefits, including:

• Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
• 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 Older homes usually have windows that are outdated, drafty or maybe even damaged in some way.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 increase the value of your property if you decide to sell.
• Decrease your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In West Mifflin, that’s about 467 pounds per year on average.
• Save on power bills: After you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll need less energy to heat or cool your home.

What Services do Window Installers Offer?

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

Full-frame installations entail replacing the total window, including the sill, trim and frame. You most likely need a full-frame installation when you want to change the style of your windows or your window has considerable damage. Because these installations are more involved, they will raise the overall cost. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are simpler and won’t carry as large a bill, but you can’t do this type of installment if you have any pre-existing rot or water damage.

If you’re still trying to decide which kind of installation to get, you can ask your installer and get their recommendation. 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 West Mifflin

The EcoWatch Reviews team differs from other reviewers because we evaluate these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in West Mifflin and ranked them using the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve West Mifflin so you can find the right window installation company near you.

Work Quality

When choosing new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the brand 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

Customer feedback is another very important review factor. If the majority of customers don’t have nice things to say about their service from a certain window installation company, it won’t be featured on EcoWatch.

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 providers’ prices, we awarded 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 give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have been in the industry for quite some time. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
