How Installing Energy-Efficient Windows in Farmington Saves You Money
Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to consider making the switch:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Reduce your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 147 pounds.
- Save money on electricity bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of energy use in your home. Upgrading to energy-efficient windows can help reduce that amount, which helps you save more on your bills.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Farmington
When researching window installation, each company provides different services and prices. Let's look at some typical costs and services.
How Much Do New Windows Cost?
The typical cost to replace one window is about $600 but can range anywhere from $200 to $1,200. This is because window installations depend on a variety of factors specific to your home, including the size, material and number of windows you need to install, as well as the location of your property.
Whether or not you choose energy-efficient windows is another factor that will affect the cost. These will almost always cost more than other windows, but on the other hand, you can save about $446 a year on your energy bills in Farmington.
We recommend getting free quotes from several window installers to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
The first step when considering a replacement is to clarify whether you need a full-frame or pocket installation.
A full-frame installation is a total window replacement. It involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve extra materials, including insulation and drip edges, which raise the overall cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any damage or rot, you will most likely need a full-frame installation instead.
Your window replacement company should be able to help you choose what's best for your needs. In Farmington, the decision will mostly be based on the age of your home and if there's any damage. Wood can decay if not properly maintained over the years, so it's a good idea to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Farmington
In our hunt to find the most reliable, eco-friendly window installers in Farmington, the EcoWatch team chose the above companies as the best window installation companies in the city. We've evaluated the best window installation companies in Farmington mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Because this is a guide for Farmington, we only included companies that serve 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 Farmington.
Work Quality
When it comes to new windows, the quality and range of services can often play just as important of a role in insulation and performance as the brand you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another very important review factor. If the majority of customers don't have good feedback about their experience with a certain window installation company, it won't be featured on EcoWatch.
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 gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Farmington's climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Farmington window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Farmington, CT Window Replacement FAQs
What is the average cost to install windows?
The typical cost to replace one window can range from $450 to $650. There are a variety of factors that influence the cost, which include how energy-efficient the windows are, the number of windows, local labor costs, your property's location, styles and sizes of windows and the materials used in designing the windows.
What are the types of windows?
There are various types of windows you can get for your house, including double-hung and single-hung windows, casement windows, picture windows, bay windows, transom windows, awning windows and slider windows.
Do I really have to use a window installation company?
You should hire a window installation company whenever you want to replace your windows. Installing windows is a complicated process that can be difficult to do on your own, so it's best left to the professionals.
How often do you need to replace your windows?
Windows generally last around 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.
Should I replace my windows all at the same time?
If you want to get more efficient windows and save money on energy costs, replacing all of your windows at once is the only way to see a noticeable difference. On the other hand, if you have just a few windows that are broken or drafty, you can replace just those.
