How Installing Energy-Efficient Windows in Hartford Saves You Money

Energy-efficient windows can offer benefits in several ways. Here are a few reasons you may want to consider making the switch:

  • Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
  • Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
  • Save money on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for about 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.

Estimated Cost of Window Replacement in Hartford

Each window replacement company offers varying services and has different price points depending on a few factors.

How Much Do New Windows Cost?

According to our market research, the typical cost of replacing a single window is about $600. However, window installation costs can range from $200 to $1,200 a window. This is because of the fact that window installations depend on several factors specific to your home, such as the size, material and number of windows you need to install, as well as where your property is located.

It's important to remember that windows with the best efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Hartford homeowners $437+ a year when replacing single-pane windows.

We recommend getting free quotes from multiple window installation companies to find the one that works best for your budget.

What Services do Window Installers Offer?

The first thing to ask yourself when considering a window replacement is: Do you need a full-frame installation or a pocket installation?

A full-frame installation replaces the complete window, including the windowsill, frame, trim and the window panes. Because this kind of installation is more involved, it will be more expensive than a pocket installation. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations more simple and affordable. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.

If you're still trying to decide which kind of installation to get, you can talk to your provider and get their advice. The choice mostly is influenced by how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Hartford

EcoWatch reviews are different from most reviews because we assess these companies through a sustainability lens. We have assessed the top window installers in Hartford mostly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows have been shown to lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for Hartford, we only included companies that cover the city. There are certainly other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Hartford.

Work Quality

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

Customer Reviews

Customer feedback is another very important review factor. If the majority of customers don't have good feedback about their service from a certain company, you won't see it featured on EcoWatch.

Cost

This one is a give-and-take: as with most services, cheap window installation 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

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

Years of Experience

Lastly, we like to see companies that have been in the industry for quite some time. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Hartford, CT Window Replacement FAQs

How much does window installation cost?

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

Which kind of window is the best?

A window's energy efficiency depends on several factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.

Do I really have to use a window installation company?

Unless you have experience with home improvement projects and have all the tools you need to replace your own windows, we recommend hiring the pros. The window installation process is complex and can take anywhere from four to six hours for a single window. Although it's tempting to try to save some money by doing it yourself, hiring a company is a faster, more efficient and safer option.

How long does window installation typically take?

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

When is it time to replace your windows?

Windows generally have a lifespan of about 20 to 30 years, but anytime you see damage on your windows, it's a good idea to have them looked at by an expert to determine if they are in need of a repair or replacement.
