Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Although eco-friendly energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your home’s energy efficiency can also have a considerable impact on home energy conservation. If you have outdated, drafty windows, your HVAC system could be working overtime to heat or cool your house. This means spending more on electric bills.

Replacement windows improve your home’s insulation, not only making you more comfortable during extreme temperatures, but also saving you some money and helping the environment.

Efficient windows are of particular importance in Newtown, where the temperature varies throughout the year. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $312 a year.

How Installing Energy-Efficient Windows in Newtown Saves You Money

There are quite a few perks of upgrading to energy-efficient windows. A few reasons you may want to consider making the switch include the following:

  • Save money on energy bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% because you use less energy.
  • Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Newtown, that’s about 286 pounds per year on average.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also 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 Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.

Estimated Cost of Window Replacement in Newtown

Each window replacement company offers varying services and has different prices based on a few factors.

How Much Do New Windows Cost?

On average, Newtown homeowners can anticipate their window installations to range from $250 to $1,200. The most common installations sit at approximately $600. This is because of the fact that window installations are based on a variety of factors specific to your home, like the size, material and number of windows you need to replace, as well as where your property is located.

Whether or not you want to install energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $312 a year on your energy bills in Newtown.

Costs will also vary based on the material you pick for your window frames. Aluminum frames are the least expensive. They’re sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

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

A full-frame installation replaces the full window, such as the windowsill, frame, trim and the window panes. As this kind of installation requires more time, it will cost more than a pocket installation. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

If you’re still trying to decide which type of installation you should get, you can consult with your provider and get their advice. The decision mostly is influenced by how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Newtown

In our search to make your home improvements easier and more eco-friendly in Newtown, EcoWatch assessed many companies before landing on these. Along with energy efficiency, we reviewed each installer and assigned rankings based on the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find a quality 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 tons of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have positive feedback about their experience with a certain window installation company, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: as with most services, cheap window installation companies may not provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.

Warranty

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

Years of Experience

Due to Newtown’s climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Newtown window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

Newtown, PA Window Replacement FAQs

What is the average cost to install windows in a home?

The average cost to install a single window ranges between $450 and $650. There are many factors that affect the price, which include how energy-efficient the windows are, local labor costs, your property’s location, the materials used in designing the windows, the number of windows and styles and sizes of windows.

Which kind of window is the best?

A window’s energy efficiency depends on a variety of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.

When should I use a window installation company?

You should hire a window installation company whenever you want to replace your windows. Installing windows is a involved process that can take a lot of time, so it’s best handled by the professionals.

How often do you need to replace your windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to operate, they may be in need of replacement.

Should I replace all my windows at once?

If you’re upgrading your windows because of energy-efficiency, replacing all of your windows together is the only way to gain that benefit. On the other hand, if you have just one or two windows that are broken or drafty, you can replace just those.
