How Installing Energy-Efficient Windows in Amherst Saves You Money

When you switch to energy-efficient windows, you may see a few benefits, such as:

  • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
  • 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 Older homes usually have windows that are outdated, drafty or maybe even damaged in some way.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 raise the value of your home if you decide to sell.
  • Save on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Switching to energy-efficient models can help decrease how much you have to pay, therefore saving you about 12% more on your bills.
  • Decrease your carbon footprint: By using less energy after upgrading to energy-efficient windows, you’ll also be reducing your carbon dioxide emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Amherst

Each window installation company provides various services and has different price points depending on a few factors.

How Much Do New Windows Cost?

Typically, homeowners in Amherst can anticipate that most window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. How much it will cost varies based on several factors, like number of windows, type, material, size, the location of your home and more.

With windows, efficiency is one of the most important factors for most homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — especially during the winter — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Amherst homeowners $463+ each year after replacing single-pane windows.

We recommend requesting free quotes from multiple window installation companies to find the one that works best for your budget.

What Services do Window Installers Offer?

The first step when planning a replacement is to clarify whether you need a full-frame or pocket installation.

Full-frame installations entail replacing the total window, including the frame, trim and sill. You most likely need a full-frame installation when you want a new style or your window has significant deterioration. Because these installations are more involved, they will raise the overall cost. Pocket installations are on the simpler end and won’t carry as large a bill because they involve simply replacing the window within its existing frame. But if the frame has any damage, you should opt for a full-frame installation instead.

Your window installation company will be able to recommend the best type for your project. In Amherst, the decision will mostly depend on the efficiency of your home and how old your existing frames are.

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 examined dozens of companies before deciding on these. Along with energy efficiency, we assessed each installer and ranked them using the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve the Amherst area so you can find the best window installation company near you.

Work Quality

We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer on this list to make sure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent customer feedback to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across nearly every category, including warranty, quality of installation, quality of parts, cost, professionalism and more.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers’ prices, we awarded higher points 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 provide 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 experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Amherst, NH Window Replacement FAQs

How much should a window install cost?

The national average cost of replacing a window is around $600 but can range between $200 and $1,200, depending on a variety of factors. The price is typically dependent on the type and material of the window, the location of your property and the size of the window. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

Which type of window should I get?

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 have the most energy-efficient windows, look for models with the blue Energy Star certification — that means they’re certified energy-efficient by the U.S. Department of Energy.

When do I need to use a window installation company?

You should hire a window installation company whenever you need to replace your windows. Installing windows is a complicated process that can take a lot of time, so it’s best left to the professionals.

When is it time to replace your windows?

Windows generally have a lifespan of around 20 to 30 years, but anytime you see damage on your windows, it’s a good time to have them looked at by an expert to determine if they are in need of a repair or replacement.

How long does window installation usually take?

Because the average installation time of a window is 30 minutes, about 16 windows can be installed during an 8-hour work day.
