How Installing Energy-Efficient Windows in Jacksonville Saves You Money

When you switch to energy-efficient windows, you may see several benefits, including:

• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
• Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
• Save on power bills: Installing energy-efficient windows reduces your energy bills by about 12% because you use less energy.
• Reduce your carbon footprint: In Jacksonville, you can lower your indirect greenhouse gas emissions by about 642 pounds per year after you switch to energy-efficient windows.

Estimated Cost of Window Replacement in Jacksonville

Let’s take a look at the cost of installing new windows and the types of services offered by installers.

How Much Do New Windows Cost?

On average, Jacksonville homeowners can expect their replacement window installations to range from $250 to $1,200. The average cost sits at around $600. These numbers vary based on the specifics of your installation, such as type, size, the location of your home, material, number of windows and more.

It’s also worth keeping in mind that energy-efficient windows will usually cost more initially, but Energy Star estimates that upgrading the windows on your Jacksonville home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you’ll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Asking for free quotes from multiple installers is the best way to find out which one is right for you.

What Services do Window Installers Offer?

In regard to window replacements, there are generally two types that your installer will offer: full-frame and pocket installations.

Full-frame installations are usually done when you want a new style or your window has significant rot or deterioration. With this service, your professionals will replace the entire window, including the sill, trim and frame. Pocket installations are simpler and won’t carry as large a bill because they involve merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you should opt for a full-frame installation instead.

Your window installation company will be able to advise you on the best type for your project. In Jacksonville, the decision will mostly depend on the efficiency of your home and the condition of your existing frames.

How We Choose the Best Window Installers in Jacksonville

In our hunt to make your home improvements easier and more eco-friendly in Jacksonville, EcoWatch chose the above companies as the top window installation companies in the city. Along with energy efficiency, we assessed window companies all across the state and assigned rankings based on the following methodology:

Service Area

Since this is a guide for Jacksonville, we gave more points to companies that provide services to the city. There are other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Jacksonville.

Work Quality

We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each company in our guide to ensure its technicians are well-qualified and that the company has received tons 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 nice things to say about their experience with a certain company, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: as with other services, cheap window installation companies may not provide the most quality service. On the other hand, we want to ensure 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 to many homeowners. That’s why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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