How Installing Energy-Efficient Windows in Farmington Saves You Money
There are several benefits of switching to energy-efficient windows. Some reasons you may want to consider making the change include the following:
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
- Decrease your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by 152 pounds per year on average.
- Save money on power bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Replacing your windows with energy-efficient models can help decrease how much you have to pay, therefore saving you about 12% more on your bills.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
Estimated Cost of Window Replacement in Farmington
Windows come in different styles, purposes and shapes, so costs and services will vary greatly based on several factors. Below, we go over the typical cost and services that you can get from window installation companies.
How Much Do New Windows Cost?
The average cost to install one window is about $600 but can range anywhere from $200 to $1,200. How much it will cost you varies based on several factors, like type, number of windows, material, the location of your home, size and more.
It's also worth noting that energy-efficient windows will usually cost more initially, but Energy Star estimates that upgrading the windows on your Farmington home translates to 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. How much you'll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
We advise getting free quotes from several window companies to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
The first step when planning a window installation is to think about whether you want a full-frame or pocket installation.
Full-frame installations are usually recommended when you want to change the style of your windows or your window has a lot of rot. With this service, your professionals will replace the total window, including the sill, trim and frame. A pocket installation involves replacing a window within the existing frame, which tends to be cheaper than a full-frame installation.
Your window installation company can advise you on the best type for your project. In Farmington, the choice will mostly be based on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Farmington
EcoWatch is different from other reviewers because we look at these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in Farmington and assigned rankings using the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find a quality window installation company near you.
Work Quality
When installing new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the type of window you get. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent customer feedback to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including professionalism, warranty, quality of parts, cost, quality of installation and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers' prices, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a serious investment, so you'll want to make sure that investment is well protected. Window installation companies that give you 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 installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Farmington, NH Window Replacement FAQs
How much should window installation cost?
The national average cost to replace a single window is around $600 but can range between $200 and $1,200, based on a few different factors. The price is usually dependent on the type and material of the window, the size of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What kind of window is the best for energy efficiency?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you'll get the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.
When do I have to use a window installation company?
Unless you have experience with home improvement projects and have the tools needed 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 one window. Although it's tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and safer option.
How long does window installation usually take?
Because the average installation time of a window is 30 minutes, around 16 windows can be installed in an 8-hour work day.
Should I replace my windows all at once?
If you want to get more efficient windows and save money on energy costs, replacing all your windows at once is the only way to see a noticeable difference. On the other hand, if you have just one or two windows that are damaged or leaky, you can replace just those.
