Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Although eco-friendly energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your house's energy efficiency can also have a big impact on home energy conservation. If your house has old or damaged windows, your AC or heater could be working overtime to heat or cool your house. This means spending more on energy bills.

Thankfully, saving you money with upgraded windows also aligns with our goals of reducing energy usage for the environment.

Efficient windows are especially important in East Merrimack, where winters are long and cold. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $463 per year.

How Installing Energy-Efficient Windows in East Merrimack Saves You Money

Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to make the switch:

  • Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
  • Reduce your carbon footprint: By using less energy after you upgrade to Energy Star certified windows, you'll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Save on power bills: The Department of Energy estimates that heat gained or lost via windows accounts for about 25-30% of residential energy use. Switching to energy-efficient windows can help lower that amount, which helps you save $463 a year on your bills.

Estimated Cost of Window Replacement in East Merrimack

Each window installation company offers various services and has varying prices depending on several factors.

How Much Do New Windows Cost?

The national average cost to install one window is about $600 but can range from $200 to $1,200. Costs will differ significantly depending on the current condition of your home, the number of windows you need, the quality of your products and your location. Many window companies also offer door installations and other add-ons like shutters, baths, coating and more. These extra services will increase overall project costs.

Bear in mind that energy-efficient windows may cost more upfront, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you install single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.

Getting free quotes from several installers is the best way to figure out which one will work best for your budget.

What Services do Window Installers Offer?

In general, there are two kinds of window replacement services you can get: full-frame and pocket installations.

Full-frame installations entail replacing the complete 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 noticeable rot or deterioration. Full-frame installations are more involved and will raise the total cost. A pocket installation means replacing a window without taking out the entire frame, which is usually less expensive than a full-frame installation.

If you're hiring a reputable window installation company, your company can recommend the best type for your project. In East Merrimack, the decision will mostly be based on the efficiency of your home and the age and condition of your existing frames.

How We Choose the Best Window Installers in East Merrimack

EcoWatch reviews differ from most reviews because we evaluate these companies through a sustainability lens. We've decided to evaluate the top window installers in East Merrimack primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

This one is self-explanatory, but we've chosen to highlight window installers that serve East Merrimack so you can find the right window installation company near you.

Work Quality

When choosing new windows, the quality and range of services can often play 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

Another self-explanatory yet very important review factor is customer feedback. If most customers don't have nice things to say about their experience with a certain window installation company, you won't see it featured on EcoWatch.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed previously, windows are a hefty investment, so you'll want to be certain that investment is protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have been in the industry for quite some time. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

East Merrimack, NH Window Replacement FAQs

What is the typical cost to install windows?

The typical cost of replacing one window can range between $450 and $650. There are several factors that influence how much it costs, which include styles and sizes of windows, how energy-efficient the windows are, local labor costs, the number of windows, the materials used in designing the windows and your property's location.

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 don't open are more efficient than windows that do. To be sure you're getting the most energy-efficient windows, look for models that have the blue Energy Star certification — that means they're certified energy-efficient by the U.S. Department of Energy.

Can I install my own windows?

If you're handy and have experience with similar home improvement projects, you may be able to install your own windows. However, if you don't have the time or skills, we recommend hiring a professional.

How long does it usually take to install windows?

Because a window takes about 30 minutes to install, about 16 windows can be installed during an 8-hour work day.

How often do you need to replace windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may be in need of replacement.
