How Installing Energy-Efficient Windows in Key Largo Saves You Money

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

• Save on electricity bills: After you install energy-efficient windows, you can see a reduction in your bills by about 12% since you’ll need less energy to heat or cool your home.
• Reduce your carbon footprint: Reducing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 390 pounds.
• Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
• Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.

Estimated Cost of Window Replacement in Key Largo

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

How Much Do New Windows Cost?

On average, Key Largo homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at around $600. This is because window installations depend on several 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.

Whether or not you choose energy-efficient windows is another factor that will affect the cost. These will almost always cost more than other windows, but on the other hand, you can save about $423 a year on your energy bills in Key Largo.

Another factor that affects the overall cost is the material you choose for your frame. Aluminum frames are usually the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

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 removing the old window, the windowsill, and the exterior and interior trim. It can also involve other materials, like insulation and drip edges, which raise the overall cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are on the simpler end and won’t cost as much because they involve simply replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.

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

How We Choose the Best Window Installers in Key Largo

EcoWatch reviews differ from other reviews, as we assess these companies through a sustainability lens. We have assessed the best window installation companies in Key Largo mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

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 a quality window installation company near you.

Work Quality

We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each company on this list to ensure its technicians are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have positive feedback about their service from a certain company, you won’t see it featured on EcoWatch.

Cost

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

Years of Experience

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