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.

A review of the best window installation companies in Loudon may not seem like the most captivating article on EcoWatch, but trust us, windows have more of an impact on your life than you might realize. Damaged or outdated windows can cost you in energy bills. As a matter of fact, the Department of Energy estimates that 25-30% of your home's heat or cool air could be lost through your windows.

That's also bad for the environment, as the extra energy used by drafty windows increases your carbon footprint.

Because windows have such a great impact on your home, picking the right company for you is a big choice to make. That's why the EcoWatch team has put together this list of the best window installation companies, so you can make an informed decision more easily.

How Installing Energy-Efficient Windows in Loudon Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here's more information on how switching out your windows could help you:

  • 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 Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
  • Save on energy bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% because you use less energy.
  • Decrease your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Loudon, that's about 152 pounds per year on average.
  • Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.

Estimated Cost of Window Replacement in Loudon

When researching window installation, each company offers different services and costs. Let's go over some typical costs and services.

How Much Do New Windows Cost?

On average, Loudon homeowners can expect their window installations to range from $250 to $1,200. The average cost is at around $600. These figures vary depending on specific characteristics of your installation, like the location of your home, number of windows, material, size, type and more.

Whether or not you want energy-efficient windows is another factor that will influence the cost. These will almost always cost more than other windows, but on the other hand, you can save about $477 a year on your energy bills in Loudon.

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

What Services do Window Installers Offer?

There are typically two types of window installation services: full-frame and pocket installations.

A full-frame installation is a total window replacement. It involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves extra materials, such as insulation and drip edges, which raise the total cost of the project. It's also worth noting that you may have to touch up the paint around the window after a full-frame installation. A pocket installation involves replacing a window without replacing the frame. So, instead of tearing out the whole window and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

If you're still debating which kind of installation to get, you can consult with your provider and get their advice. The choice mostly depends on how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Loudon

EcoWatch reviews are different from most reviews, as we're examining these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer and ranked them using the following methodology:

Service Area

Since this is a guide for Loudon, we paid more attention to companies that provide services to the city. There are certainly other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Loudon.

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 get. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

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

Cost

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

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of Loudon's climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Loudon window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Loudon, NH Window Replacement FAQs

What is the average cost to install new windows in a home?

The national average cost to replace a window is about $600 but can range between $200 and $1,200, based on a few different factors. The price is usually influenced by the location of your property, the type and material of the window and the size of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

What are the most common types of replacement windows?

The most common types of windows for homes are awning windows, casement windows, bay windows, picture windows, slider windows, double-hung and single-hung windows and transom windows.

What services do window replacement companies offer?

Window installation professionals cover the entire process — from replacing old windows with brand new ones to cleaning up after the windows have been put in place. In addition, some companies offer window manufacturing, customization and repairs.

How often should you replace windows?

Windows usually have a lifespan of 20 to 30 years, but anytime you notice damage on your windows, it's a good time to have them looked at by an expert to see if they need any repairs or replacements.

Should I replace my windows all at the same time?

If you want to get more efficient windows and save money on your energy bills, replacing all of your windows together is the only way to gain that benefit. On the other hand, if you have just a few windows that are broken or leaky, you can replace just those.
