How Installing Energy-Efficient Windows in Groton Saves You Money

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

• Save money on power bills: Switching to energy-efficient windows reduces your energy bills by about 12% since you need less energy.
• Decrease your carbon footprint: In Groton, you can lower your indirect greenhouse gas emissions by about 139 pounds per year after you upgrade to energy-efficient windows.
• Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Groton

Windows come in various shapes and sizes, so costs and services will differ remarkably. Here are the average costs and services that you can find from window installation companies.

How Much Do New Windows Cost?

According to our market research, the typical cost to replace a single window is around $600. However, window replacement costs can range from $200 to $1,200 a window. But costs vary remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door replacements, which have a higher price tag.

With windows, efficiency is one of the most important factors for most homeowners. High efficiency windows may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Groton homeowners $464+ a year after replacing single-pane windows.

We advise requesting free quotes from multiple window installation companies to find the right windows and the company that works best for your budget.

What Services do Window Installers Offer?

Generally, there are two types of window installation services companies provide: full-frame and pocket installations.

Full-frame installations are necessary when you want a new style or your window has significant deterioration. With this service, your professionals will replace the complete window, including the trim, sill and frame. A pocket installation involves replacing a window within the existing frame. So, instead of taking out the whole unit and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company should be able to help you choose what’s best for your needs. In Groton, the decision will mostly be based on the age of your windows and if there’s any moisture damage. Wood can decay if it’s not properly maintained over the years, so it’s a good idea to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Groton

In our search to make your home improvements easier and more eco-friendly in Groton, EcoWatch examined many companies before settling on these. Along with energy efficiency, we reviewed several window installers in Groton and assigned rankings using the following methodology:

Service Area

Because this is a guide for Groton, we gave more points to companies that provide services to the city. There are other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Groton.

Work Quality

When it comes to new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the brand you opt for. 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 find the companies with the most consistent customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including cost, quality of installation, warranty, professionalism, quality of parts and more.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed previously, windows are a serious 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

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