How Installing Energy-Efficient Windows in Gantt Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are a few reasons you may want to make the switch:
- Reduce your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 415 pounds.
- Save on energy bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of energy use in your home. Installing energy-efficient windows can help decrease that number, which helps you save $357 a year on your bills.
- Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its value.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
Estimated Cost of Window Replacement in Gantt
Let's go over the cost of replacing your windows and the types of services you may need for your home.
How Much Do New Windows Cost?
The average cost to install a single window is about $600 but can range from $200 to $1,200. These numbers vary depending on specific characteristics of your installation, including material, size, number of windows, type, the location of your home and more.
It's also worth keeping in mind that energy-efficient windows will almost always cost more upfront, but Energy Star predicts that upgrading the windows on your Gantt home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you'll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Costs will also vary depending on the material you pick for your window frames. Aluminum frames are the least expensive. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made using 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 offer decent insulation for your home.
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 is a replacement of the total window. It involves removing the old window, the windowsill, and the exterior and interior trim. It also involves additional materials, such as insulation and drip edges, which increase 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. A pocket installation involves replacing a window within the existing frame. So, instead of tearing out the whole window 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 kind of installation you need, you can ask your provider and get their advice. The decision mostly is influenced by how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Gantt
EcoWatch differs from other reviewers since we examine these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in Gantt and assigned rankings based on the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve Gantt so you can find the right window installation company near you.
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 on this list to make sure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including professionalism, warranty, cost, quality of parts, quality of installation and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we awarded higher points 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 that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Gantt, SC Window Replacement FAQs
What is the typical cost to install windows in a home?
The average cost to replace a single window ranges between $450 and $650. There are a variety of factors that affect the cost, including styles and sizes of windows, the materials used in designing the windows, the number of windows, how energy-efficient the windows are, your property's location and local labor costs.
Which type of window should I get?
A window's energy efficiency is affected by several factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.
What do window installation companies do?
Window installation professionals go to your home to remove your old windows and replace them with new ones. Some providers install products manufactured by other companies, whereas others install their own windows. The installer will also clean up after the installation.
How long does it typically take to install windows?
Since the average installation time is 30 minutes per window, about 16 windows can be installed in an 8-hour work day.
Should I replace my windows all at the same time?
If you're upgrading your windows to get more efficient windows, replacing all of the windows together is the only way to see a noticeable difference. However, if you have only a few windows that are broken or leaky, you can replace just those.
