How Installing Energy-Efficient Windows in Thompson Saves You Money
By upgrading to energy-efficient windows, you can enjoy several benefits, including:
- Save money on electricity bills: Once you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll require less energy to heat or cool your home.
- 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 Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way.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 increase the value of your home if you decide to sell.
- Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out harmful UV rays.
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Thompson, that's about 147 pounds per year on average.
Estimated Cost of Window Replacement in Thompson
When researching window installation, each company provides different services and costs. Let's go over some typical costs and services.
How Much Do New Windows Cost?
Typically, homeowners in Thompson can expect that most replacement window installations will range from $250 to $1,200, with the average cost sitting at around $600. These estimates are based on the specifics of your installation, like the location of your home, type, material, size, number of windows and more.
It's also worth keeping in mind that energy-efficient windows will almost always cost more initially, but Energy Star predicts that upgrading the windows on your Thompson home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you'll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Another factor that influences the total cost is the material you select for your frame. Aluminum frames are usually the least pricey and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
There are typically two kinds of window installation services: full-frame and pocket installations.
Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has a great amount of deterioration. Full-frame installations involve more time and labor and will increase overall costs. 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 unsure which type of window installation service you need, your installer can advise you. Typically, the choice is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Thompson
EcoWatch differs from other reviewers, as we assess these companies through a sustainability lens. We've assessed the top window replacement companies in Thompson primarily based on energy efficiency, as it's the most sustainable option and the best one for homeowners. 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 installation companies that serve the Thompson area so you can find a quality window installation company near you.
Work Quality
We're certain that you're looking for professionals who do a great job installing windows. We've vetted each installer featured in our guide to make sure its contractors are well-qualified and that the company has gotten tons 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 positive things to say about their service from a certain window installation company, you won't see it featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing the prices of providers, we gave higher scores 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 that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Thompson's climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Thompson window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Thompson, CT Window Replacement FAQs
How much should a window install cost?
The national average cost to install one window is around $600 but can range from $200 to $1,200, depending on several factors. The price is generally influenced by the size of the window, the location of your property and the type and material 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.
What type of window is the most energy-efficient?
A window's energy efficiency is influenced by several factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.
Do you really have to use a window installation company?
Unless you have home repair skills 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 company is a faster, more efficient and safer alternative.
What time of year is the best time to replace my windows?
Even though you can install windows any time of year, warmer weather is often better for installing replacement windows. Additionally, it shouldn't be raining, since rain can make the installation more difficult.
Should I replace my windows all at once?
If your windows are more than 20 years old, you most likely need to replace all of them. By that point, they are typically less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
