How Installing Energy-Efficient Windows in Mauldin Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here are more details about how switching out your windows could help you:
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
- Better temperature control in your home: Energy-efficient windows can reduce how much cool air is lost through your windows when cooling your home.
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Mauldin, that's about 415 pounds per year on average.
- More efficient energy usage in your home: Because the winters can get very chilly in Mauldin, homeowners usually rely on their heater during that time. Energy-efficient windows reduce how much heat is lost through your windows, making it easier to keep your house warm.
Estimated Cost of Window Replacement in Mauldin
Each window installer offers various services and has different costs depending on a few factors.
How Much Do New Windows Cost?
Generally, homeowners in Mauldin can anticipate that most replacement window installations will range from $250 to $1,200, with the most common installations sitting at about $600. How much it will cost you varies depending on several factors, including the location of your home, material, number of windows, size, type and more.
It's important to bear in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save Mauldin homeowners $357+ a year when replacing single-pane windows.
How much your window installation costs will also vary depending on the kind of window material you choose for the frames. Wood windows are typically the most expensive, but it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
In general, there are two kinds of window installation services companies offer: full-frame and pocket installations.
Full-frame installations are usually recommended when you want a new style or your window has a lot of rot or deterioration. With this service, your installers will replace the total window, including the frame, trim and sill. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
Your window installation company should be able to help you choose which type of installation you need.

How We Choose the Best Window Installers in Mauldin
In our search to make your home improvements easier and more eco-friendly in Mauldin, EcoWatch assessed many companies before settling on these. Along with energy efficiency, we evaluated several window installers in Mauldin and assigned rankings based on the following methodology:
Service Area
Because this is a guide for Mauldin, we gave more points to companies that provide services to the city. There are certainly reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Mauldin.
Work Quality
When it comes to new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the type of window you get. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don't have good feedback about their experience with a certain company, you won't see it featured on EcoWatch.
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 the prices of providers, we awarded higher scores 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 with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Mauldin, SC Window Replacement FAQs
How much should a window install cost?
The national average cost to install a window is about $600 but can range from $200 to $1,200, depending on several factors. The price is typically dependent on the size of the window, the location of your property and the type and material of the window. Also, keep in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
What are the different types of windows?
The most common types of windows for homes are casement windows, picture windows, double-hung and single-hung windows, slider windows, awning windows, bay windows and transom windows.
When do I need to use a window installation company?
You should hire a window installation company whenever you want new windows. Installing windows is a involved process that can be difficult and time-consuming, so it's best handled by the professionals.
Should I replace my windows all at once?
If you're upgrading your windows to get more efficient windows, replacing all the windows at once is the only way to gain that benefit. On the other hand, if you have just a few windows that are broken or drafty, you can replace just those.
