How Installing Energy-Efficient Windows in Greenville Saves You Money

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

• Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if you have an older home.
• Decrease your carbon footprint: By using less energy after upgrading to energy-efficient windows, you’ll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.
• Save on power bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of residential energy use. Switching to energy-efficient windows can help reduce that number, which helps you save $357 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.

Estimated Cost of Window Replacement in Greenville

Windows come in different purposes, styles and shapes, so costs and services will differ tremendously based on several factors. Below, we detail the average cost and services that you can get from window installation companies.

How Much Do New Windows Cost?

Typically, homeowners in Greenville can anticipate that most window installations will cost between $250 and $1,200, with the average cost at about $600. But prices vary considerably 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 installations and replacements, which will make your project cost more.

With windows, efficiency is one of the most important factors for most homeowners. High efficiency windows may cost more initially, but by increasing the efficiency of your home — particularly if you live in a hot climate — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Greenville homeowners $357+ a year after replacing single-pane windows.

Costs will also vary based on the material of your frame. Aluminum frames are the least expensive. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

The first step when planning a window replacement is to figure out whether you should get a full-frame or pocket installation.

Full-frame installations are necessary when you want a new style or your window has a lot of rot. With this service, your professionals will replace the whole window, including the trim, frame and sill. A pocket installation involves replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.

Your window installation company should be able to help you choose which type of installation you need.

How We Choose the Best Window Installers in Greenville

The EcoWatch Reviews team differs from other reviewers, as we’re examining these companies through a sustainability lens. We have assessed the top window installers in Greenville mostly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows have been shown to lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for Greenville, we gave more points to companies that provide services to the city. There are other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Greenville.

Work Quality

We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each installer included in our guide to make sure its technicians are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent online reviews to determine the companies with the highest rates of customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including cost, quality of installation, professionalism, warranty, quality of parts and more.

Cost

This one is a give-and-take: similar to most services, cheap window installers may not provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that offer a spectrum of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed, windows are a serious investment, so you’ll want to be certain that investment is protected. Window installation companies that give you 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 installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
