How Installing Energy-Efficient Windows in Thompson Saves You Money

When you switch to energy-efficient windows, you may see a few perks, such as:

  • Save on power bills: Because energy-efficient windows reduce how much energy you need to heat or cool your home, the switch can help you save around $457 annually on your energy bills in Thompson.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, especially if you have an older home.
  • Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Thompson

Let's go over the cost of window installation and the kinds of services offered by installers.

How Much Do New Windows Cost?

According to our market research, the average cost of installing a single window is around $600. However, window replacement costs can range from $200 to $1,200 a window. These estimates vary based on specific characteristics of your installation, such as the location of your home, material, number of windows, size, type and more.

With windows, efficiency is the most important factor for many homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Thompson homeowners $457+ per year after replacing single-pane windows.

Something else that affects the overall cost is the material of the frame you choose. Aluminum frames are typically the least expensive and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

The first question to ask yourself when getting new windows is: Should you get a full-frame installation or a pocket installation?

Full-frame installations are usually done when you want a new style or your window has a lot of rot. With this service, your professionals will replace the full window, including the sill, frame and trim. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any rot or deterioration, you will likely need a full-frame installation instead.

If you're still trying to decide which kind of installation you need, you can consult with your installer and get their recommendation. The decision mostly depends on how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Thompson

In our search to make your home improvements easier and more eco-friendly in Thompson, the EcoWatch Reviews team chose the above companies as the top window installation companies in the city. We have evaluated the top window installers in Thompson mainly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows have been shown to lower power 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 Thompson, we paid more attention to companies that provide services to the city. There are certainly reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Thompson.

Work Quality

When picking new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the type of window you opt for. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

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

Cost

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

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a proven track record in the industry. 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.

Thompson, CT Window Replacement FAQs

What is the average cost to replace windows?

The national average cost to install a window is around $600 but can range from $200 to $1,200, based on a few different factors. The price is generally dependent on the location of your property, the size of the window and the type and material of the window. Also, keep in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.

What type of window is the best for energy efficiency?

A window's energy efficiency is affected by a number of factors, such as 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.

Can you install your own windows?

If you're handy and have the time and patience to do the job right, it's possible to install your own windows. But if you don't have the time or experience, we recommend getting a professional to do it for you.

How long does window installation typically take?

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

What time of year should I replace my windows?

Replacement windows can be installed during any season, but warmer weather is typically better. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into your house, so the temperature outside doesn't necessarily matter that much. What's most important is that the weather should be dry.
