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.

A review of the best window replacement companies in Newtown may not seem like the most riveting article on EcoWatch, but trust us, windows impact your life more than you might think. The Department of Energy estimates that heat gained or lost through outdated or drafty windows could account for about 30% of heating and cooling usage. In Newtown, where the electric bills are an average of $39 per month, that's almost $$140 per year wasted.

That's also bad for the environment, as the extra energy required by leaky windows increases your carbon footprint.

So if you're building a new home, renovating or updating your windows in Newtown, you've found the best place to get started.

How Installing Energy-Efficient Windows in Newtown Saves You Money

When you upgrade to energy-efficient windows, you may see a few perks, such as:

  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
  • Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its value.
  • Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 147 pounds per year on average.
  • Save money on electricity bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of household energy use. Upgrading to energy-efficient windows can help lower that number, which helps you save some money on your bills.

Estimated Cost of Window Replacement in Newtown

Each window installation company offers varying services and has different price points based on a few factors.

How Much Do New Windows Cost?

According to our market research, the typical cost of replacing a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. Costs will vary significantly based on the number of windows you need, the current condition of your home, your location and the quality of your products. A lot of window companies also offer replacement door installations and other add-ons like baths, shutters, coating and more. Additional services will increase your overall project costs.

It's important to bear in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Newtown homeowners $441+ a year when replacing single-pane windows.

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

What Services do Window Installers Offer?

In regard to window installations, there are generally two types that your installer will have: full-frame and pocket installations.

Full-frame installations require replacing the full window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has a great amount of deterioration. Full-frame installations are more involved and will increase overall costs. A pocket installation means replacing a window within the existing frame, which is usually less expensive than a full-frame installation.

Your window replacement company will be able to help you choose what's best for your needs. In Newtown, the decision will mostly be based on how old your windows are and if there's any damage. Wood can decay if not properly maintained over the years, so it's good to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Newtown

EcoWatch reviews are different from most reviews because we examine these companies through a sustainability lens. We've reviewed the top window installers in Newtown mainly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Since this is a guide for Newtown, we gave more points to companies that serve the city. There are certainly other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Newtown.

Work Quality

We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each company in our guide to make sure its technicians are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent customer feedback to find 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 indicates the quality of services across most other categories, including quality of installation, cost, warranty, quality of parts, professionalism and more.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed, windows are a hefty investment, so you'll want to make sure that investment is well protected. Window installation companies that offer 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 a good track record in the industry. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

Newtown, CT Window Replacement FAQs

How much does a window install cost?

The average cost of replacing one window can range between $450 and $650. There are several factors that influence the price, such as the number of windows, local labor costs, the materials used in designing the windows, how energy-efficient the windows are, your property's location and styles and sizes of windows.

What type of window is the most energy-efficient?

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

Can I install my own windows?

If you're handy and have experience with similar home improvement projects, you may be able to install your own windows. But if you don't have the time or skills, we don't recommend doing it on your own.

What time of year is a good time to replace my windows?

Replacement windows can be installed during any season, but warmer weather is typically better. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your home, so the temperature outside isn't necessarily a big factor. Most importantly, the weather should be dry.

How often do you need to replace windows?

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