How Installing Energy-Efficient Windows in Amherst Saves You Money
When you upgrade to energy-efficient windows, you may see some perks, including:
- Save on power bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of household energy use. Upgrading to energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
- Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
Estimated Cost of Window Replacement in Amherst
Windows come in different shapes, purposes and styles, so costs and services will differ remarkably depending on your project. Below, we detail the typical cost and services that you'll find from window replacement companies.
How Much Do New Windows Cost?
Generally, homeowners in Amherst can anticipate that most window installations will range from $250 to $1,200, with the most common installations sitting at around $600. Costs will vary considerably depending on your location, the current condition of your home, the quality of your products and the number of windows you need. Many window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. Additional services will increase your overall project costs.
It's important to bear in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Amherst homeowners $463+ a year when replacing single-pane windows.
Requesting free quotes from multiple installers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
The first step of a window installation is to clarify whether you want a full-frame or pocket installation.
Full-frame installations entail replacing the total window, including the sill, frame and trim. Full-frame installations are necessary when you want to change the style of your windows or your window has noticeable rot or deterioration. Because full-frame installations are more involved, they will increase the overall cost. Pocket installations are on the simpler end and won't cost as much because they involve merely replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.
Your window replacement company will be able to help you figure out what's best for your needs. In Amherst, the decision will mostly depend on how old your home is and if there's any damage. Wood can decay if it's not properly maintained over the years, so it's a good idea to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Amherst
In our hunt to make your home improvements easier and more eco-friendly in Amherst, the EcoWatch Reviews team chose the above companies as the top window installation companies in the city. Along with energy efficiency, we evaluated window companies all across the state and ranked them based on the following methodology:
Service Area
Because this is a guide for Amherst, we paid more attention to companies that cover the city. There are other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Amherst.
Work Quality
When it comes to new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the type of window 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
We analyzed trends in recent customer feedback to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including warranty, professionalism, cost, quality of installation, quality of parts and more.
Cost
This one is a give-and-take: as with other services, cheap window companies may not provide the highest quality service. Still, we want to ensure we're highlighting companies that offer a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a significant investment, so you'll want to be certain that investment is protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, 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.
Amherst, NH Window Replacement FAQs
How much does window installation cost?
The typical cost to install one window can range from $450 to $650. There are many factors that affect the price, including your property's location, the number of windows, the materials used in designing the windows, local labor costs, how energy-efficient the windows are and styles and sizes of windows.
Which kind of window is the best?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open are more efficient than windows that do. To be sure you'll have 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.
Can I install my own windows?
Although you can install your own windows, doing so is time-consuming and requires a lot of handiness. Using a window replacement company can help guarantee that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.
How long does it usually take to install windows?
Each window takes about 30 minutes to install depending on the kind of window. However, the window installation can take two days or more if you have a lot of windows that must be installed.
Should I replace all my windows at the same time?
If you want to get more efficient windows and save money on your energy bills, replacing all of the windows at the same time is the only way to see a noticeable difference. On the other hand, if you have only a few windows that are damaged or leaky, you can replace just those.
