How Installing Energy-Efficient Windows in Fort Mill Saves You Money
Energy-efficient windows can offer benefits in several ways. Here are some reasons you may want to consider making the switch:
- Save money on energy bills: Once you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll need less energy to heat or cool your home.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
- Decrease your carbon footprint: In Fort Mill, you can cut your indirect greenhouse gas emissions by about 415 pounds per year when you upgrade to energy-efficient windows.
- Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading and repairing your windows is an important part of maintaining your property and its value.
Estimated Cost of Window Replacement in Fort Mill
Windows come in varying shapes and sizes, so costs and services will differ tremendously. Here are the average costs and the primary services that you’ll find from window installers.
How Much Do New Windows Cost?
Even though the national average cost of installing one window is about $600, it can range from $200 to $1,200. But costs will vary considerably based on the number of windows you need, the current condition of your home, your location and the quality of your products. A lot of window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. These extra services will increase overall project costs.
Bear in mind that energy-efficient windows may come at a higher price tag, but Energy Star estimates the upgrade will save you between $101 and $583 per year when installing single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.
Another factor that influences the overall cost is the material of the frame you choose. Aluminum frames are usually the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
There are generally two types of window replacement services: full-frame and pocket installations.
Full-frame installations are usually done when you want to change the style of your windows or your window has significant rot. With this service, your installers will replace the complete window, including the trim, sill and frame. A pocket installation involves installing a new window without replacing the frame. So, instead of tearing out the whole window and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.
If you’re still debating which type of installation you should get, 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 Fort Mill
In our search to find the most reliable, eco-friendly window installers in Fort Mill, the EcoWatch team examined dozens of companies before deciding on these. Along with energy efficiency, we assessed window companies all across the state and ranked them based on the following methodology:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve the Fort Mill area 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 company in our guide to make sure its contractors 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 super important review factor is customer feedback. If most customers don’t have good things to say about their experience with a certain company, you won’t see it featured on EcoWatch.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed previously, windows are a hefty investment, so you’ll want to make sure that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Fort Mill’s climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Fort Mill window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Fort Mill, SC Window Replacement FAQs
What is the average cost to replace windows?
The average cost to install a single window can range from $450 to $650. There are several factors that affect the price, including local labor costs, styles and sizes of windows, the materials used in designing the windows, the number of windows, how energy-efficient the windows are and your property’s location.
Which kind of window is the best?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. If you want to be sure you’ll have the most energy-efficient windows, look for models that have the blue Energy Star certification — that means they’re certified energy-efficient by the U.S. Department of Energy.
Can you replace your own windows?
While you can install your own windows, doing so requires a lot of time and experience with home improvement projects. Using a window replacement company can help ensure that the job is done properly and that you can avoid spending the time and effort of doing it yourself.
Should I replace all my windows at the same time?
If your windows are greater than 20 years old, it’s probably time to replace all of them. By that point, they are usually less efficient, leakier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less stress.
How long does window installation generally take?
Each window takes around 30 minutes to install based on the type of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
