How Installing Energy-Efficient Windows in Glastonbury Saves You Money

Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to think about making the switch:

  • Save on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Switching to energy-efficient models can help reduce how much energy is used in your home, therefore saving you about 12% more on your bills.
  • Decrease your carbon footprint: By using less energy once you switch to Energy Star certified windows, you'll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
  • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Updating 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 your floors, carpets and furniture from fading by filtering out UV rays.

Estimated Cost of Window Replacement in Glastonbury

Windows come in various shapes and sizes, so costs and services will vary remarkably. Here are the typical costs and the primary services that you can find from window installers.

How Much Do New Windows Cost?

On average, homeowners in Glastonbury can expect that most window installations will range from $250 to $1,200, with the average cost at around $600. But costs will differ considerably depending on the current condition of your home, your location, the number of windows you need and the quality of your products. A lot of window companies also offer replacement door installations and other add-ons like coating, baths, shutters and more. Additional services will increase overall project costs.

It's also worth bearing in mind that energy-efficient windows will cost more upfront, but Energy Star predicts that upgrading the windows on your Glastonbury home translates to an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you'll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

We recommend getting free quotes from several window companies to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

There are typically two types of window replacement services: full-frame and pocket installations.

A full-frame installation replaces the complete window, including the windowsill, frame, trim and the window panes. Because this kind of installation requires more time and labor, it will be more expensive than a pocket installation. A pocket installation entails replacing a window without replacing the frame. This means instead of removing the whole unit and reinstalling it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.

If you're hiring a reputable window installation company, your company can advise you on the best type for your project. In Glastonbury, the decision will mostly depend on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Glastonbury

The EcoWatch Reviews team is different from most reviewers since we assess these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and ranked them using the following methodology:

Service Area

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

Work Quality

We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each company on this list to ensure its technicians are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have nice things to say about their experience with a certain installer, you won't see it featured on EcoWatch.

Cost

This one is a give-and-take: as with other services, cheap window installers are not going to provide the most quality service. Still, we want to make sure 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 significant 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

Lastly, we like to see companies that have a good track record in the industry. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Glastonbury, CT Window Replacement FAQs

What is the typical cost to replace windows in a home?

The typical cost to replace one window ranges from $450 to $650. There are a variety of factors that affect how much it costs, which include styles and sizes of windows, local labor costs, the materials used in designing the windows, your property's location, the number of windows and how energy-efficient the windows are.

Which kind of window should I get?

A window's energy efficiency is affected by a number of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.

Do you really have to use a window installation company?

You should use a window installation company whenever you want to replace your windows. Installing windows is a involved process that can be difficult and time-consuming, so it's best left to the professionals.

How long does window installation typically take?

Since the average installation time is 30 minutes per window, about 16 windows can be installed during a typical 8-hour work day.

Should I replace my windows all at the same time?

If you're upgrading your windows to get more efficient windows, replacing all of your windows at once is the only way to see a noticeable difference. However, if you have just one or two windows that are broken or drafty, you can replace just those.
