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

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

  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of energy use in your home. Installing energy-efficient windows can help lower that number, which helps you save more on your bills.
  • Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Keeping your windows up to date is an important part of maintaining your property and its value.

Estimated Cost of Window Replacement in New London

Windows come in varying shapes and sizes, so costs and services will differ greatly. Here are the average costs and the primary services that you'll find from window installation companies.

How Much Do New Windows Cost?

According to our research, the average cost of installing a single window is around $600. However, window installation costs can range from $200 to $1,200 per window. How much it will cost you is based on several factors, such as size, type, material, number of windows, the location of your home and more.

It's important to note that windows with the best efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save New London homeowners $477+ a year when replacing single-pane windows.

We recommend getting free quotes from multiple window installers to find the one that works best for your budget.

What Services do Window Installers Offer?

In general, there are two kinds of window installation services you can get: full-frame and pocket installations.

A full-frame installation is a total window replacement. It involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve extra materials, such as insulation and drip edges, which raise the overall cost of the project. Also worth noting: it's not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and will be less expensive, but you can't do this kind of installment if you have any pre-existing rot or water damage.

If you're still debating which type of installation to get, you can ask your installer and get their recommendation. The decision mostly depends on the age of your window frames and if there's any damage.

How We Choose the Best Window Installers in New London

EcoWatch reviews are different from most reviews because we examine these companies through a sustainability lens. We have evaluated the top window installation companies in New London mostly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Since this is a guide for New London, we only included companies that cover the city. There are certainly reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in New London.

Work Quality

When installing new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand of window 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 patterns in recent online reviews to determine the companies with the most consistent 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 quality of parts, warranty, quality of installation, professionalism, 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. On the other hand, we want to make sure we're highlighting companies that offer a variety of price and financing options so they're accessible to most homeowners.

Warranty

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

Years of Experience

Because of New London's climate, homeowners need to be wary of rot, low efficiency and water damage. 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.

How much should a window install cost?

The national average cost to install a window is about $600 but can range from $200 to $1,200, based on several factors. The price is generally influenced by the size of the window, the location of your property and the type and material of the window.

What do window installers do?

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

What time of year should I replace my windows?

Replacement windows can be installed during any season, but warmer weather is typically better. Regardless of 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. What's most important is that the weather should be dry.

When is it time 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 any damage on them, or they have become difficult to operate, they may need to be replaced.
