How Installing Energy-Efficient Windows in Clemson Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here's more information on how upgrading your windows could help you:
- Decrease your carbon footprint: In Clemson, you can reduce your indirect greenhouse gas emissions by about 415 pounds per year after you install energy-efficient windows.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
- Save money on energy bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of household energy use. Installing energy-efficient windows can help reduce that amount, which helps you save some money on your bills.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
Estimated Cost of Window Replacement in Clemson
Windows come in varying styles, shapes and purposes, so costs and services will vary considerably depending on several factors. Below, we go over the typical cost and services that you'll find from window installers.
How Much Do New Windows Cost?
Generally, Clemson homeowners can expect their window replacements to range from $250 to $1,200. The average cost sits at around $600. These amounts vary based on the specifics of your installation, such as the location of your home, type, size, number of windows, material and more.
It's important to note that windows with higher efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Clemson homeowners $418+ a year when replacing single-pane windows.
We recommend getting free quotes from multiple window companies to find the one that works best for you.
What Services do Window Installers Offer?
Generally, there are two kinds of window replacement services companies provide: full-frame and pocket installations.
A full-frame installation is a replacement of the full window. It involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve additional materials, like insulation and drip edges, which raise the total cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. A pocket installation involves replacing a window within the frame that's already there. So, instead of tearing out the whole window and rebuilding it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.
If you're still trying to decide which type of installation you need, you can talk to your provider and get their advice. The decision mostly depends on how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Clemson
EcoWatch reviews differ from other reviews since we examine these companies through a sustainability lens. We've reviewed the top window installation companies in Clemson mostly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Because this is a guide for Clemson, we paid more attention to companies that serve the city. There are other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Clemson.
Work Quality
When installing new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the brand of window you choose. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don't have positive feedback about their experience with a certain company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window installation companies are not going to provide the most 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
As discussed previously, windows are a substantial investment, so you'll want to make sure that investment is protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Clemson's climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of Clemson window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Clemson, SC Window Replacement FAQs
How much should a window install cost?
The national average cost of installing a single window is around $600 but can range from $200 to $1,200, based on a variety of factors. The price is often dependent on the size of the window, the type and material of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
Which kind of window should I get?
A window's energy efficiency is influenced by a variety of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.
Can I install my own windows?
Although it is possible to install your own windows, doing so requires a lot of time and handiness. Using a window replacement company can help guarantee that the job is done properly and that you can avoid spending the time and effort of doing it yourself.
When is it time to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to operate, they may need to be replaced.
