How Installing Energy-Efficient Windows in Rock Hill Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here are more ways upgrading your windows could benefit you:
- Save on power bills: Once you install energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll require less energy to heat or cool your home.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.
- 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.
- Decrease your carbon footprint: By using less energy after switching to energy-efficient windows, you’ll also be reducing your carbon dioxide emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Rock Hill
Windows come in different styles, purposes and shapes, so costs and services will vary tremendously based on your project. Below, we go over the average cost and services that you can get from window installation companies.
How Much Do New Windows Cost?
Although the average cost of replacing one window is around $600, it can range anywhere from $200 to $1,200. But costs vary considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door replacements, which will add extra costs to your project.
It’s also worth bearing in mind that energy-efficient windows will cost more initially, but Energy Star estimates that switching out the windows on your Rock Hill home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you’ll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Requesting free quotes from multiple providers is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
There are typically two kinds of window installation services: full-frame and pocket installations.
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 other materials, including insulation and drip edges, which increase the total cost of the project. It’s also worth noting that you may have to touch up the paint around the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and won’t carry as large a bill, but you can’t do this kind of installment if you have any pre-existing rot or water damage.
If you’re unsure which kind of window installation service you should get, your installer should be able to advise you. Typically, the choice depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Rock Hill
EcoWatch reviews differ from other reviews because we look at these companies through a sustainability lens. We have decided to evaluate the best window installation companies in Rock Hill primarily based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Because this is a guide for Rock Hill, we paid more attention to companies that serve the city. There are certainly other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Rock Hill.
Work Quality
When installing new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand you opt for. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including cost, quality of installation, professionalism, warranty, quality of parts and more.
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 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. For that reason, window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a proven track record in the industry. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Rock Hill, SC Window Replacement FAQs
How much does a window install cost?
The national average cost of installing one window is about $600 but can range from $200 to $1,200, based on a few different factors. The price is often dependent on the size of the window, the location of your property and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What type of window is the most energy-efficient?
A window’s energy efficiency depends on a variety of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.
When should I use a window installation company?
You should hire a window installation company whenever you want to upgrade your windows. Installing windows is a complicated process that can take a lot of time, so it’s best left to the professionals.
When is the best time of year to replace windows?
While you can install windows any time of year, warmer weather is usually better for replacing windows. In addition, the weather should be dry, as rain can make the installation harder.
Should I replace all my windows at the same time?
If you want to get more efficient windows and save money on your energy bills, replacing all the windows together is the only way to gain that benefit. On the other hand, if you have only one or two windows that are broken or drafty, you can replace just those.
