How Installing Energy-Efficient Windows in Groton Saves You Money

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

  • Save money on electricity bills: The Department of Energy estimates that heat gained or lost via windows accounts for about 25-30% of energy use in your home. Upgrading to energy-efficient windows can help reduce that number, which helps you save more on your bills.
  • Reduce your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 147 pounds.
  • Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.

Estimated Cost of Window Replacement in Groton

Windows come in all shapes and sizes, so costs and services will vary considerably. Here are the typical costs and services that you'll find from window installers.

How Much Do New Windows Cost?

According to our research, the national average cost of replacing a single window is around $600. However, window installation costs can range from $200 to $1,200 a window. But prices differ considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door installations, which will make your project cost more.

With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — especially 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 $424+ a year after replacing single-pane windows.

Another factor that influences the overall cost is the material you pick for your frame. Aluminum frames are generally the least pricey and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

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

A full-frame installation is a replacement of the total window. This service involves removing the old window, the sill, and the exterior and interior trim. It also involves additional materials, such as insulation and drip edges, which increase 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. A pocket installation entails installing a new window within the old frame. So, instead of removing the whole window and rebuilding it, the window installer 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 depend on the age of your windows and if there's any damage. Wood can decay if it's not properly maintained over the years, so it's good to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Groton

The EcoWatch Reviews team differs from other reviewers because we assess these companies through a sustainability lens. We have assessed the best window installation companies in Groton mostly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find the best window installation company near you.

Work Quality

When it comes to new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the type of window you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent customer feedback to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including warranty, cost, quality of parts, professionalism, quality of installation and more.

Cost

This one is a give-and-take: similar to most services, cheap window installation companies may not provide the highest quality service. Still, we want to ensure we're highlighting companies that provide a wide range of price and financing options so they're accessible to most homeowners.

Warranty

As discussed previously, windows are a sizable investment, so you'll want to be certain that investment is well protected. Window installation companies with lengthy warranties for products, parts and labor 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 years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Groton, CT Window Replacement FAQs

How much does a window install cost?

The national average cost to replace a single window is around $600 but can range from $200 to $1,200, depending on a few different factors. The price is generally dependent on the size of the window, the location of your property and the type and material of the window. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.

What are the most common types of replacement windows?

There are several different types of windows you can get for your home, including slider windows, transom windows, bay windows, awning windows, picture windows, double-hung and single-hung windows and casement windows.

Do you really need to use a window installation company?

You should hire a window installation professional whenever you need to upgrade your windows. Installing windows is a complex process that can be difficult to do on your own, so it's best left to the professionals.

How often do you need to replace your windows?

Windows typically have a lifespan of about 20 to 30 years, but anytime you notice damage on your windows, it's a good time to have them checked by an expert to determine if they are in need of a repair or replacement.

Should I replace my windows all at once?

If your windows are more than 20 years old, you probably need to replace all of them. By that point, they are often less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
