How Installing Energy-Efficient Windows in Mount Vernon Saves You Money

Upgrading to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here are more details about how upgrading your windows could help you:

  • Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of energy use in your home. Installing energy-efficient windows can help decrease that amount, which helps you save $302 a year on your bills.
  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
  • 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 Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way.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 increase the value of your property if you decide to sell.
  • Reduce your carbon footprint: By using less energy after upgrading to energy-efficient windows, you’ll also be decreasing your indirect greenhouse gas emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Mount Vernon

When considering window installation, each company provides varying services and prices. Let’s go over some average costs and services.

How Much Do New Windows Cost?

Generally, homeowners in Mount Vernon can expect that most window installations will range from $250 to $1,200, with the average cost sitting at around $600. These estimates are based on specific characteristics of your installation, like material, size, number of windows, type, the location of your home and more.

It’s also worth keeping in mind that energy-efficient windows will usually cost more initially, but Energy Star estimates that switching out the windows on your Mount Vernon home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 per 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.

Requesting free quotes from several providers is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

When it comes to window installations, there are generally two types that your provider will offer: full-frame and pocket installations.

A full-frame installation replaces the entire window, such as the sill, frame, trim and the window panes. Because this kind of installation is more involved, it will cost more than a pocket installation. A pocket installation means replacing a window without taking out the complete frame, which is generally less expensive than a full-frame installation.

If you’re still trying to decide which kind of installation you need, you can consult with your installer and get their recommendation. The decision mostly is influenced by the age of your window frames and if there’s any damage present.

How We Choose the Best Window Installers in Mount Vernon

EcoWatch reviews differ from other reviews since we evaluate these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in Mount Vernon and assigned rankings using the following methodology:

Service Area

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

Work Quality

We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each installer on this list to make sure its contractors are well-qualified and that the company has gotten plenty 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. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including quality of parts, cost, warranty, quality of installation, professionalism and more.

Cost

This one is a give-and-take: similar to other services, cheap window installation companies won’t always provide the most quality service. Still, we want to ensure we’re highlighting companies that provide a variety 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 have lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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