How Installing Energy-Efficient Windows in Hartford 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 switch are the following:

  • Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
  • Save on power bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of energy use in your home. Installing energy-efficient windows can help reduce that amount, which helps you save more on your bills.

Estimated Cost of Window Replacement in Hartford

Each window installer offers varying services and has varying price points depending on several factors.

How Much Do New Windows Cost?

The average cost to install one window is about $600 but can range anywhere from $200 to $1,200. How much it will cost is based on several factors, such as size, the location of your home, material, number of windows, type and more.

Keep in mind that energy-efficient windows may have a higher price, but Energy Star estimates the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 per year when installing double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.

The cost of your window installation will also vary depending on the kind of material you choose for the frames. Wood windows are generally the most expensive, though 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 more efficient.

What Services do Window Installers Offer?

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

A full-frame installation is a replacement of the full window. It involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves extra materials, such as insulation and drip edges, which raise the total cost of the project. It’s also worth noting that you may have to touch up the paint around the window after a full-frame 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 kind of installment if you have any pre-existing rot or water damage.

Your window installation company will be able to help you choose what’s best for your needs. In Hartford, the decision will mostly be based on the age of your home and if there’s any moisture damage. Wood can decay if it’s not properly maintained over the years, so it’s a good idea to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Hartford

The EcoWatch Reviews team differs from other reviewers because we evaluate these companies through a sustainability lens. We’ve reviewed the best window installation companies in Hartford mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can reduce 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 pretty self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find a quality window installation company near you.

Work Quality

When choosing new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand you get. 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 trends in recent online reviews to find the companies with the most consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including quality of parts, cost, quality of installation, warranty, professionalism and more.

Cost

This one is a give-and-take: as with most services, cheap window companies are not going to provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that offer a variety 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 give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

Hartford, VT Window Replacement FAQs

How much does window installation cost?

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

What kind of window is the best for energy efficiency?

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

When should I use a window installation company?

Unless you’re handy and have all the tools you need to replace your own windows, we recommend hiring the pros. The window installation process is quite involved and can take anywhere from four to six hours for a single window. Although it’s tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and safer option.

What time of year should I replace my windows?

Although you can install windows any time of year, warmer weather is generally better for installing replacement windows. Additionally, it shouldn’t be raining, as rain can make the installation harder.

How often do you need to replace windows?

Windows typically 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 determine if they need any repairs or replacements.
