How Installing Energy-Efficient Windows in South Charleston Saves You Money

By switching to energy-efficient windows, you can take advantage of several benefits, including:

• Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.
• Save on electricity bills: Installing energy-efficient windows lowers your energy bills by about 12% since you use less energy.
• 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.
• Reduce your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In South Charleston, that’s about 777 pounds per year on average.

Estimated Cost of Window Replacement in South Charleston

Windows come in all shapes and sizes, so costs and services will differ remarkably. Here are the average costs and services that you’ll find from the average window installation company.

How Much Do New Windows Cost?

On average, South Charleston homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at approximately $600. How much it will cost is based on several factors, including size, the location of your home, type, number of windows, material and more.

It’s important to note that windows with the best efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save South Charleston homeowners $340+ a year when replacing single-pane windows.

Costs will also vary based on the material of your frame. Aluminum frames have the lowest price. They’re sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also provide 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?

In regard to window replacements, in general there are two kinds that your provider will have: full-frame and pocket installations.

A full-frame installation replaces the total window, such as the windowsill, frame, trim and the window panes. Because this type of installation is more involved, it will cost more than a pocket installation. A pocket installation entails installing a new window within the frame that’s already there. This means instead of taking out the whole unit and reinstalling it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

If you’re still debating which type of installation to get, you can ask your installer and get their recommendation. The decision mostly is influenced by the age of your window frames and if there’s any damage present.

How We Choose the Best Window Installers in South Charleston

EcoWatch reviews differ from other reviews because we examine these companies through a sustainability lens. We’ve decided to assess the best window installation companies in South Charleston mainly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve the South Charleston area so you can find a quality window installation company near you.

Work Quality

When selecting new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand you get. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent online reviews to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including cost, warranty, quality of installation, quality of parts, professionalism and more.

Cost

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

Warranty

Protecting your investment in new windows is important. That’s why window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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