How Installing Energy-Efficient Windows in Greenland Saves You Money

There are several perks of upgrading to energy-efficient windows. A few reasons you may want to consider making the switch include the following:

  • Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
  • Save on electricity bills: After you switch to energy-efficient windows, you can see a reduction in your bills by about 12% because you'll require less energy to heat or cool your house.
  • 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.

Estimated Cost of Window Replacement in Greenland

Let's take a look at the cost of window replacement and the kinds of services offered by installers.

How Much Do New Windows Cost?

The typical cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. But costs differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door replacements, which will add extra costs to your project.

Whether or not you want energy-efficient windows is another factor that will determine the cost. These will typically cost more than other windows, but on the other hand, you can save about $435 a year on your energy bills in Greenland.

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

What Services do Window Installers Offer?

When considering window replacements, there are typically two types that your provider will have: full-frame and pocket installations.

Full-frame installations are usually done when you want a new style or your window has a lot of rot or deterioration. With this service, your professionals will replace the full window, including the trim, frame and sill. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and will be less expensive, but you can't do this kind of installment if you have any pre-existing rot or water damage.

Your window replacement company will be able to help you choose what's best for your needs. In Greenland, the decision will mostly depend on how old your home is and if there's any moisture damage. Wood can decay if it's not maintained properly over the years, so it's a good idea to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Greenland

In our search to find the most reliable, eco-friendly window installers in Greenland, EcoWatch chose the above companies as the top window installation companies in the city. We have decided to evaluate the top window installers in Greenland mainly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installers that serve the Greenland area so you can find a quality window installation company near you.

Work Quality

When picking new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand 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

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have positive things to say about their experience with a certain company, it won't be featured on EcoWatch.

Cost

This one is a give-and-take: similar to most services, cheap window companies may not provide the most quality service. Still, we want to ensure we're highlighting companies that offer a range of price and financing options so they're accessible to most homeowners.

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that have 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 been in the industry for a while. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Greenland, NH Window Replacement FAQs

What is the typical cost to install new windows?

The average cost of replacing one window ranges from $450 to $650. There are many factors that influence the price, such as how energy-efficient the windows are, the materials used in designing the windows, the number of windows, local labor costs, styles and sizes of windows and your property's location.

Which type of window is the best?

A window's energy efficiency depends on a number of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.

Can you install your own windows?

Even though it is possible to install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Hiring a professional 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 take to install windows?

Each window takes around 30 minutes to install depending on the type of window. However, the window installation can take two days or more if you need to have a lot of windows installed.

How do you know it's time to replace your windows?

Windows generally have a lifespan of 20 to 30 years, but anytime you notice damage on your windows, it's a good idea to have an expert take a look at them to see if they are in need of a repair or replacement.
