How Installing Energy-Efficient Windows in Newtown Saves You Money

When you switch to energy-efficient windows, you may see several perks, including:

  • More efficient energy use in your household: Because the winters can get very cold in Newtown, homeowners often rely on their heater a lot. Energy-efficient windows reduce how much heat is lost through your windows, making it easier to keep your home warm.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Protect your investment: If you have a relatively old home, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
  • Save money on power bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of energy use in your home. Upgrading to energy-efficient windows can help decrease that amount, which helps you save more on your bills.

Estimated Cost of Window Replacement in Newtown

Windows come in various styles, shapes and purposes, so costs and services will differ considerably based on several factors. Below, we detail the average cost and services that you can get from window installation companies.

How Much Do New Windows Cost?

On average, Newtown homeowners can expect their window replacements to range from $250 to $1,200. The average cost sits at about $600. This is because window installations depend on a variety of factors specific to your home, including the size, material and number of windows you need to install, as well as the location of your property.

It's also worth bearing in mind that energy-efficient windows will usually cost more initially, but Energy Star estimates that upgrading the windows on your Newtown home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you'll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

Something else that affects the overall cost is the material you pick for your frame. Aluminum frames are generally the least expensive and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

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

Full-frame installations entail replacing the full window, including the frame, sill and trim. You most likely need a full-frame installation when you want a new style or your window has significant deterioration. Because full-frame installations are more involved, they will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler and won't cost as much, but you can't do this kind of installment if you have any pre-existing rot or water damage.

If you're still trying to decide which kind of installation you should get, you can consult with your provider and get their advice. The choice mostly depends on the age of your window frames and if there's any damage.

How We Choose the Best Window Installers in Newtown

The EcoWatch Reviews team differs from most reviewers since we examine these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in Newtown 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 Newtown area so you can find the right window installation company near you.

Work Quality

We're willing to bet that you're looking for a company to do a great job installing windows. We've vetted each company featured in our guide to ensure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent online reviews to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across nearly every category, including warranty, quality of parts, professionalism, quality of installation, cost and more.

Cost

This one is a give-and-take: similar to most services, cheap window installers are not going to provide the most quality service. Still, 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 previously, windows are a hefty investment, so you'll want to be certain that investment is well protected. Window installation companies that have 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 low efficiency, rot and water damage. We factored in local experience to reflect the ability of Newtown window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Newtown, CT Window Replacement FAQs

What is the average cost to replace windows?

The average cost of replacing a window can range from $450 to $650. There are several factors that influence how much it costs, which include how energy-efficient the windows are, the number of windows, styles and sizes of windows, your property's location, local labor costs and the materials used in designing the windows.

What kind of window is the best for energy efficiency?

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

Can you install your own windows?

If you're handy and have the time and patience to do the job right, it's possible to install your own windows. However, if you don't have the time or know-how, we recommend hiring a professional.

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 your windows together is the only way to see a noticeable difference. On the other hand, if you have only a few windows that are broken or leaky, you can replace just those.
