How Installing Energy-Efficient Windows in Lunenburg Saves You Money

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

• Reduce your carbon footprint: By using less energy after switching to energy-efficient windows, you’ll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.
• Save on electricity bills: Since energy-efficient windows reduce how much energy you need to heat or cool your home, they can help you save around $482 annually on your energy bills in Lunenburg.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its value.

Estimated Cost of Window Replacement in Lunenburg

Each window replacement company provides various services and has varying costs depending on a few factors.

How Much Do New Windows Cost?

Even though the typical cost of installing one window is about $600, it can range anywhere from $200 to $1,200. This is because window installations are based on a variety of factors specific to your home, such as the size, material and number of windows you need to install, as well as where your property is located.

It’s also worth noting that energy-efficient windows will usually cost more initially, but Energy Star predicts that switching out the windows on your Lunenburg home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you’ll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

What Services do Window Installers Offer?

In regard to window replacements, there are typically two kinds that your provider will offer: full-frame and pocket installations.

Full-frame installations are usually recommended when you want to change the style of your windows or your window has significant deterioration. With this service, your professionals will replace the whole window, including the trim, sill and frame. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler and won’t carry as large a bill, but you can’t do this type of installment if you have any pre-existing rot or water damage.

Your window installation company will be able to help you choose what’s best for your needs. In Lunenburg, the decision will mostly be based on the age of your home and if there’s any damage. Wood can decay if it’s not maintained properly over the years, so it’s good to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Lunenburg

In our hunt to make your home improvements easier and more eco-friendly in Lunenburg, the EcoWatch 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 Lunenburg, we only included companies that provide services to the city. There are certainly other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Lunenburg.

Work Quality

We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each company included on this list to make sure its contractors are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent online reviews to find the companies with the most consistent customer satisfaction. Customer satisfaction might be the most important factor, as it indicates the quality of services across nearly every category, including cost, warranty, quality of installation, professionalism, quality of parts and more.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers’ prices, we awarded higher scores 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 offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of Lunenburg’s climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Lunenburg window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
