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

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

• Reduce your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Key Biscayne, that’s about 390 pounds per year on average.
• Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Installing energy-efficient models can help reduce how much energy is used in your home, therefore saving you about 12% more on your bills.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
• Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if your home is on the older side.

Estimated Cost of Window Replacement in Key Biscayne

Windows come in varying purposes, styles and shapes, so costs and services will vary considerably depending on several factors. Below, we describe the typical cost and services that you can get from window installation companies.

How Much Do New Windows Cost?

The typical cost to replace one window is about $600 but can range anywhere from $200 to $1,200. But costs differ remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door replacements, which have a higher price tag.

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

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

What Services do Window Installers Offer?

When considering window installations, there are generally two kinds that your provider will have: full-frame and pocket installations.

Full-frame installations are usually done when you want to change the style of your windows or your window has a lot of rot or deterioration. With this service, your installers will replace the full window, including the trim, frame and sill. Pocket installations are on the simpler end and won’t cost as much because they involve merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.

Your window installation company can recommend the best type for your project. In Key Biscayne, the decision will mostly depend on the efficiency of your home and the age and condition of your existing frames.

We’ve evaluated the top window installation companies in Key Biscayne primarily 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 Key Biscayne so you can find a quality window installation company near you.

Work Quality

When installing new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the type of window you get. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent customer feedback to find the companies with the highest rates of customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including quality of parts, professionalism, warranty, quality of installation, cost and more.

Cost

This one is a give-and-take: as with other services, cheap window installation companies won’t always provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed previously, windows are a serious investment, so you’ll want to make sure that investment is protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a good track record in the industry. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
