How Installing Energy-Efficient Windows in Granby Saves You Money

By switching to energy-efficient windows, you can take advantage of several benefits, including:

  • Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your investment: If you have a relatively old home, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.
  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
  • Save money on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of household energy use. Upgrading to energy-efficient windows can help reduce that amount, which helps you save more on your bills.

Estimated Cost of Window Replacement in Granby

Let’s take a look at the cost of replacing your windows and the types of services you may need for your home.

How Much Do New Windows Cost?

Though the average cost to install a single window is about $600, it can range anywhere from $200 to $1,200. Costs will differ considerably depending on the current condition of your home, the quality of your products, the number of windows you need and your location. A lot of window companies also offer door installations and other add-ons like baths, shutters, coating and more. Additional services will increase your overall project costs.

It’s also worth keeping in mind that energy-efficient windows will almost always cost more upfront, but Energy Star estimates that switching out the windows on your Granby home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per 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.

How much your window installation costs will also vary based on the type of material you choose for the frames. Wood windows are usually the most expensive, but it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

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

Full-frame installations require replacing the entire window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has a great amount of rot or deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and won’t carry as large a bill, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

If you’re still trying to decide which kind of installation you should get, you can ask your provider and get their advice. The decision mostly depends on how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Granby

The EcoWatch Reviews team differs from most reviewers, as we’re examining these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and ranked them based on the following methodology:

Service Area

Because this is a guide for Granby, we only included companies that cover the city. There are other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Granby.

Work Quality

We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each company featured in our guide to make sure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another very important review factor. If most customers don’t have good things to say about their experience with a certain window installation company, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: similar to other services, cheap window companies won’t always provide the most quality service. Still, we want to ensure we’re highlighting companies that offer a wide range of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important to many homeowners. That’s why 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 been in the industry for quite some time. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Granby, CT Window Replacement FAQs

How much should a window install cost?

The typical cost of replacing a window ranges from $450 to $650. There are many factors that influence the cost, which include how energy-efficient the windows are, the number of windows, local labor costs, styles and sizes of windows, your property’s location and the materials used in designing the windows.

Which kind of window is the best?

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

What do window installers do?

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

How often do you need to replace your windows?

Windows usually have a lifespan of around 20 to 30 years, but anytime you notice damage on your windows, it’s a good idea to have an expert take a look at them to see if they need any repairs or replacements.

How long does window installation take?

Each window takes around 30 minutes to install based on the kind of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
