How Installing Energy-Efficient Windows in Thornbury Saves You Money

By upgrading to energy-efficient windows, you and your family can take advantage of several benefits, including:

  • Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Thornbury, that's about 286 pounds per year on average.
  • Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if your home is on the older side.
  • 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.
  • Save on power bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% since you use less energy.

Estimated Cost of Window Replacement in Thornbury

Windows come in varying purposes, styles and shapes, so costs and services will vary considerably depending on several factors. Below, we detail the typical cost and services that you'll find from window installation companies.

How Much Do New Windows Cost?

Generally, homeowners in Thornbury can anticipate that most replacement window installations will cost between $250 and $1,200, with the average cost at about $600. But costs differ remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door installations, which will add extra costs to your project.

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

Getting free quotes from several installers is the best way to find out which one will work best for your budget.

What Services do Window Installers Offer?

The first thing to ask yourself when planning a window installation is: Should you get a full-frame installation or a pocket installation?

Full-frame installations involve replacing the full window, including the frame, sill and trim. Full-frame installations are necessary when you want a new style or your window has considerable damage. Full-frame installations are more involved and will increase overall costs. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations more simple and affordable. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

Your window installation company should be able to help you choose which type of installation you need.

How We Choose the Best Window Installers in Thornbury

The EcoWatch Reviews team differs from most reviewers, as we're examining these companies through a sustainability lens. Along with energy efficiency, we evaluated window companies all across the state and ranked them using the following methodology:

Service Area

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

Work Quality

We're certain that you're looking for a company to do a great job installing windows. We've vetted each company featured on this list to make sure its contractors are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another very important review factor. If most customers don't have good things to say about their service from a certain company, you won't see it featured on EcoWatch.

Cost

This one is a give-and-take: similar to most services, cheap window installation companies won't always provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that provide a range of price and financing options so they're accessible to most homeowners.

Warranty

As discussed, windows are a serious investment, so you'll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and labor 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 years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Thornbury, PA Window Replacement FAQs

What is the average cost to install windows?

The typical cost to replace a single window ranges from $450 to $650. There are a variety of factors that affect the cost, including styles and sizes of windows, the materials used in designing the windows, how energy-efficient the windows are, the number of windows, your property's location and local labor costs.

What kind of window is the most energy-efficient?

Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. To be sure you're getting the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — they're certified energy-efficient by the U.S. Department of Energy.

What services do window replacement companies offer?

Window installation professionals will do the entire process — from replacing old windows with brand new ones to cleaning up after the windows have been put in place. Additionally, many companies offer window manufacturing, customization and repairs.

How do you know it's time to replace your windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to open or close, they may need to be replaced.

Should I replace all my windows at once?

If you want to get more efficient windows and save money on your energy bills, replacing all of the windows at the same time is the only way to see a noticeable difference. On the other hand, if you have just one or two windows that are broken or drafty, you can replace just those.
