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 environmentally 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 large impact on home energy conservation. Drafty windows can reduce your home’s energy efficiency by up to 30%, according to the Department of Energy. In New London, that’s an average of $424 a year that you could save on your electric bills after making the switch.

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

So if you’re building a new home, renovating or updating your windows in New London, this is the best place to get started.

How Installing Energy-Efficient Windows in New London Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more details about how upgrading your windows could benefit you:

  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can cut your carbon footprint by about 12%, according to Energy Star.
  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if your home is on the older side.
  • Save money on electricity bills: Switching to energy-efficient windows reduces your energy bills by about 12% because you use less energy.

Estimated Cost of Window Replacement in New London

Each window replacement company offers various services and has varying costs based on a few factors.

How Much Do New Windows Cost?

Typically, New London homeowners can expect their replacement window installations to range from $250 to $1,200. The most common installations sit at approximately $600. But costs will vary significantly depending on the quality of your products, the number of windows you need, your location and the current condition of your home. A lot of window companies also offer door installations and other add-ons like shutters, baths, coating and more. These extra services will increase your overall project costs.

Keep in mind that energy-efficient windows may cost more upfront, but Energy Star predicts the upgrade will save you between $101 and $583 per year when you install single-pane windows and between $27 and $197 per year when replacing double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.

Something else that affects the total cost is the material of the frame you choose. Aluminum frames are usually the least expensive and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames cost the most 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?

In general, there are two kinds of window installation services companies provide: full-frame and pocket installations.

A full-frame installation replaces the entire window, including the sill, frame, trim and the window panes. Because this type of installation requires more time, it will cost more than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and won’t cost as much, but you can’t do this type of installment if you have any pre-existing rot or water damage.

If you’re not sure which window installation service you need, your installer should be able to help you out. Typically, the decision depends on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in New London

In our search to find the most reliable, eco-friendly window installers in New London, EcoWatch chose the above companies as the top window installation companies in the city. Along with energy efficiency, we evaluated each installer and assigned rankings using the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve New London so you can find the best window installation company near you.

Work Quality

When choosing new windows, the quality and range of services can often play just as important of a role in insulation and performance as the brand you get. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent customer feedback to find the companies with the most consistent 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 cost, quality of parts, professionalism, warranty, quality of installation and more.

Cost

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

Warranty

As discussed previously, windows are a substantial investment, so you’ll want to be certain that investment is protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

New London, CT Window Replacement FAQs

How much does window installation cost?

The national average cost to replace one window is around $600 but can range from $200 to $1,200, based on a variety of factors. The price is usually influenced by the location of your property, the size of the window and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

What type 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 are more efficient than windows that do. To be sure you’ll get the most energy-efficient windows, look for models that have the blue Energy Star certification — this means they’re certified energy-efficient by the U.S. Department of Energy.

What do window installation companies do?

Window installers travel to your home to remove your old windows and replace them with new ones. Some providers install products manufactured by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is finished.

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 the windows together is the only way to gain that benefit. On the other hand, if you have only a few windows that are damaged or leaky, you can replace just those.
