Why you can trust EcoWatch
A guide on the best window replacement companies in Thompsonville may not seem like the most interesting article on EcoWatch, but trust us, windows have a more direct impact on your life than you might think. Damaged or outdated windows can cost you in electricity bills. As a matter of fact, the Department of Energy estimates that about 30% of your house's heat or cool air could be lost through your windows.
That's also bad news for the environment, as the extra energy required by drafty windows increases your carbon footprint.
So if you're building a new home, renovating or updating your windows in Thompsonville, this is the best place to get started.

How Installing Energy-Efficient Windows in Thompsonville Saves You Money
There are several perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch include the following:
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way.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.
- Decrease your carbon footprint: In Thompsonville, you can lower your indirect greenhouse gas emissions by about 147 pounds per year after you upgrade to energy-efficient windows.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Save money on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Replacing your windows with energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
Estimated Cost of Window Replacement in Thompsonville
Windows come in varying shapes, styles and purposes, so costs and services will vary tremendously based on several factors. Below, we describe the average cost and services that you'll find from window installation companies.
How Much Do New Windows Cost?
The national average cost to replace a single window is about $600 but can range from $200 to $1,200. This is because window installations depend on a variety of factors specific to your home, such as the size, material and number of windows you need to replace, as well as the location of your property.
It's also worth noting that energy-efficient windows will almost always cost more initially, but Energy Star predicts that switching out the windows on your Thompsonville home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you'll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
How much your window installation costs will also vary based on the kind of material you choose for the frames. Wood windows are usually the most expensive, though it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
The first step of a replacement is to clarify whether you want a full-frame or pocket installation.
Full-frame installations entail replacing the full window, including the trim, frame and sill. Full-frame installations are necessary when you want to change the style of your windows or your window has noticeable damage or rot. Because full-frame installations are more involved, they will increase the overall cost. Pocket installations (also known as retrofits) are when you replace a window within its 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 still debating which kind of installation to get, you can ask your installer and get their advice. The decision mostly is influenced by how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Thompsonville
In our hunt to make your home improvements easier and more eco-friendly in Thompsonville, the EcoWatch team evaluated dozens of companies before deciding on these. Along with energy efficiency, we assessed each installer and assigned rankings based on the following methodology:
Service Area
Because this is a guide for Thompsonville, we paid more attention to companies that provide services to the city. There are certainly other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Thompsonville.
Work Quality
We're certain that you're looking for a company to do a great job installing windows. We've vetted each installer featured in our guide to make sure its technicians are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the highest rates of customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including cost, quality of installation, quality of parts, professionalism, warranty and more.
Cost
This one is a give-and-take: as with other services, cheap window installers won't always provide the most quality service. On the other hand, we want to ensure we're highlighting companies that offer a range of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. That's why 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 a while. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Thompsonville, CT Window Replacement FAQs
What is the average cost to install windows?
The typical cost of replacing one window ranges from $450 to $650. There are several factors that affect the cost, such as the materials used in designing the windows, the number of windows, how energy-efficient the windows are, your property's location, styles and sizes of windows and local labor costs.
What are the different kinds of windows?
There are several different kinds of windows you can get for your house, such as casement windows, transom windows, awning windows, picture windows, double-hung and single-hung windows, bay windows and slider windows.
Can you replace your own windows?
Even though you can install your own windows, doing so requires a lot of time and handiness. Using a window installation company can help guarantee that the job is done properly and that you won't have to spend the time and effort to do it yourself.
How long does window installation usually 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.
How often should you replace windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Other than that, if your windows have any damage on them, or they have become difficult to operate, they may be in need of replacement.
