How Installing Energy-Efficient Windows in Granby Saves You Money

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

  • Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, especially if you have an older home.
  • More efficient energy use in your household: In Granby where the summers can get pretty warm, energy-efficient windows lower the amount of cool air that is lost through your windows, which makes it easier to keep your home cool.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Installing energy-efficient models can help reduce that amount, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in Granby

Each window installation company offers various services and has varying prices depending on a few factors.

How Much Do New Windows Cost?

Generally, Granby homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at around $600. This is because of the fact that window installations depend on a variety of factors specific to your home, including the size, material and number of windows you need to replace, as well as the location of your property.

It's important to keep in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save Granby homeowners $475+ a year when replacing single-pane windows.

The cost of your window installation will also vary based on the kind of window material you choose for the frames. Wood windows are usually the most expensive, but it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

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

A full-frame installation replaces the complete window, including the windowsill, frame, trim and the window panes. As this type of installation requires more time, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and won't cost as much, but you can't do this type 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 talk to 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 Granby

EcoWatch is different from other reviewers since we assess these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer and assigned rankings using the following methodology:

Service Area

Since this is a guide for Granby, we only included companies that provide services to the city. There are certainly reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Granby.

Work Quality

We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each company in our guide to make sure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.

Customer Reviews

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

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed previously, windows are a significant investment, so you'll want to be certain that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

Granby, MA Window Replacement FAQs

What is the average cost to replace windows?

The national average cost to replace a single window is about $600 but can range from $200 to $1,200, based on several factors. The price is often dependent on the type and material of the window, the size of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.

What kind of window is the best for energy efficiency?

Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open are more efficient than windows that do. If you want to be sure you'll have the most energy-efficient windows, look for models that have the blue Energy Star certification — that means they're certified energy-efficient by the U.S. Department of Energy.

What services do window replacement companies provide?

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

How long does window installation take?

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