20 Best Window Companies in Gantt, SC (2025 Reviews)

How Installing Energy-Efficient Windows in Gantt Saves You Money

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

• Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 415 pounds.
• 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.
• Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its value.
• Save on power bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of energy use in your home. Upgrading to energy-efficient windows can help reduce that number, which helps you save some money on your bills.

Estimated Cost of Window Replacement in Gantt

Each window installer offers various services and has varying costs based on a few factors.

How Much Do New Windows Cost?

According to our market research, the national average cost to replace a single window is around $600. However, window replacement costs can range from $200 to $1,200 a window. This is because 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 install, as well as the location of your property.

It’s important to bear in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Gantt homeowners $357+ a year when replacing single-pane windows.

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

What Services do Window Installers Offer?

Generally, there are two kinds of window replacement services you can get: full-frame and pocket installations.

A full-frame installation is a total window replacement. It involves removing the old window, the sill, and the exterior and interior trim. It can also involve additional materials, including insulation and drip edges, which raise the overall cost of the project. Also worth noting: it’s not uncommon for homeowners to have to touch up the paint around 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 or deterioration, you may have to get a full-frame installation instead.

Your window installation company can recommend the best type for your project. In Gantt, the choice will mostly be based on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Gantt

EcoWatch reviews differ from most reviews, as we assess these companies through a sustainability lens. We’ve decided to evaluate the best window replacement companies in Gantt primarily based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Since this is a guide for Gantt, we paid more attention to companies that cover the city. There are certainly other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Gantt.

Work Quality

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

Customer Reviews

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

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers’ prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

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 installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have been in the industry for a while. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
