How Installing Energy-Efficient Windows in Fleming Island Saves You Money

When you upgrade to energy-efficient windows, you may see a few benefits, such as:

• Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
• Save money on energy bills: Installing energy-efficient windows lowers your energy bills by about 12% because you use less energy.
• Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help increase the value of your property if you decide to sell.
• Reduce your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Fleming Island, that’s about 390 pounds per year on average.

Estimated Cost of Window Replacement in Fleming Island

Windows come in different shapes and sizes, so costs and services will vary remarkably. Here are the typical costs and services that you can find from the average window installation company.

How Much Do New Windows Cost?

Although the typical cost to replace one window is about $600, it can range from $200 to $1,200. This is because of the fact that the cost of window installations depend on a variety of factors specific to your home, including the size, material and number of windows you need to replace, as well as where your property is located.

Bear in mind that energy-efficient windows may come at a higher price point, but Energy Star predicts the upgrade will save you between $101 and $583 per year when you install single-pane windows and between $27 and $197 a year when installing double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.

What Services do Window Installers Offer?

The first step of a replacement is to think about whether you should get a full-frame or pocket installation.

Full-frame installations involve replacing the total window, including the frame, trim and sill. Full-frame installations are necessary when you want a new style or your window has considerable damage. These installations are more involved and will increase the total cost. A pocket installation involves installing a new window without replacing the frame. This means instead of tearing out the whole unit and rebuilding it, the window installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

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

How We Choose the Best Window Installers in Fleming Island

EcoWatch reviews differ from most reviews because we’re examining these companies through a sustainability lens. Along with energy efficiency, we assessed each installer and assigned rankings based on the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the best window installation company near you.

Work Quality

We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each installer included in our guide to ensure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another very important review factor. If the majority of customers don’t have positive things to say about their experience with a certain installer, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: as with most services, cheap window installers may not provide the highest quality service. Still, we want to make sure we’re highlighting companies that provide a spectrum 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 with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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