How Installing Energy-Efficient Windows in Granby Saves You Money

By upgrading to energy-efficient windows, you and your family can take advantage of several benefits, including:

  • Reduce your carbon footprint: Reducing 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 Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
  • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Save on energy bills: Installing energy-efficient windows lowers your energy bills by about 12% since you need less energy.

Estimated Cost of Window Replacement in Granby

Windows come in different shapes and sizes, so costs and services will differ greatly. Here are the average costs and services that you can find from window installers.

How Much Do New Windows Cost?

Generally, homeowners in Granby can expect that most window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. But costs will differ considerably based on your location, the quality of your products, the current condition of your home and the number of windows you need. Many window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. These extra services will increase overall project costs.

It’s important to bear in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Granby homeowners $446+ a year when replacing single-pane windows.

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?

The first thing to ask yourself when planning to replace your windows is: Do you want a full-frame installation or a pocket installation?

Full-frame installations involve replacing the full window, including the frame, sill and trim. You most likely need a full-frame installation when you want a new style or your window has considerable rot or deterioration. These installations are more involved and will increase the overall cost. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are on the simpler end and will be less expensive, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

If you’re hiring a reputable window installation company, your company can advise you on the best type for your project. In Granby, the decision will mostly be based on how much damage there is currently and the age of your existing frames.

How We Choose the Best Window Installers in Granby

EcoWatch is different from most reviewers since we assess these companies through a sustainability lens. We’ve decided to assess the best window replacement companies in Granby primarily based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

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

Work Quality

We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each installer in our guide to ensure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

Customer Reviews

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

Cost

This one is a give-and-take: as with most services, cheap window installers may not 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. For that reason, window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Due to Granby’s climate, homeowners will want to mitigate rot, low efficiency and water damage. 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, CT Window Replacement FAQs

How much does window installation cost?

The national average cost of installing one window is about $600 but can range between $200 and $1,200, based on several factors. The price is typically influenced by the type and material of the window, the location of your property and the size of the window. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

Which type of window should I get?

A window’s energy efficiency is affected by a variety 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 installation companies do?

Window installation professionals go to your house to remove your old windows and replace them with new ones. Some providers install products manufactured by other companies, whereas others install their own windows. The installer will also clean up after the installation is finished.

How often do you need to replace your windows?

Windows usually last 20 to 30 years, but anytime you notice damage on your windows, it’s a good time to have an expert take a look at them to see if they are in need of a repair or replacement.
