How Installing Energy-Efficient Windows in Charleston Saves You Money

There are quite a few benefits of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch include the following:

• Save on electricity bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% since you need less energy.
• Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
• Reduce your carbon footprint: By using less energy after switching to Energy Star certified windows, you’ll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.
• Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help raise the value of your property if you decide to sell.

Estimated Cost of Window Replacement in Charleston

Windows come in various purposes, shapes and styles, so costs and services will differ considerably based on several factors. Below, we describe the typical cost and services that you can get from window installers.

How Much Do New Windows Cost?

Generally, homeowners in Charleston can anticipate that most replacement window installations will range from $250 to $1,200, with the average cost sitting at about $600. How much it will cost varies based on several factors, like the location of your home, material, number of windows, size, type and more.

With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more initially, but by increasing the efficiency of your home — especially during the summer and winter — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Charleston homeowners $308+ per year after replacing single-pane windows.

We advise getting free quotes from multiple window companies to find the one that works best for your budget.

What Services do Window Installers Offer?

The first thing to ask yourself when planning to replace your windows is: Do you need a full-frame installation or a pocket installation?

A full-frame installation replaces the entire window, including the windowsill, frame, trim and the window panes. Because this type of installation requires more time, it will cost more than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are simpler and won’t cost as much, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

Your window installation company will be able to help you figure out what’s best for your needs. In Charleston, the decision will mostly depend on how old your windows are and if there’s any moisture damage. Wood can decay if not maintained properly over the years, so it’s a good idea to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Charleston

In our search to find the most reliable, eco-friendly window installers in Charleston, the EcoWatch team examined dozens of companies before settling on these. We have decided to assess the top window replacement companies in Charleston mainly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

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

Work Quality

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

Customer Reviews

Customer feedback is another very important review factor. If most customers don’t have positive things to say about their service from a certain company, you won’t see it featured on EcoWatch.

Cost

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

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of Charleston’s climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of 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.
