How Installing Energy-Efficient Windows in Gaffney Saves You Money
There are quite a few perks of switching to energy-efficient windows. Some reasons you may want to consider making the switch include the following:
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if your home is on the older side.
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Gaffney, that’s about 415 pounds per year on average.
- Save on energy bills: Since energy-efficient windows decrease the amount of energy needed to heat or cool your home, the switch can help you save about $386 annually on your energy bills in Gaffney.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
Estimated Cost of Window Replacement in Gaffney
Windows come in various styles, purposes and shapes, so costs and services will vary remarkably based on several factors. Below, we go over the average cost and services that you can get from window installation companies.
How Much Do New Windows Cost?
Typically, Gaffney homeowners can expect their window installations to range from $250 to $1,200. The average cost sits at about $600. This is due to the fact that the cost of window installations depend on several factors specific to your home, including the size, material and number of windows you need to install, as well as the location of your property.
Bear in mind that energy-efficient windows may have a higher price, but Energy Star estimates the upgrade will save you between $101 and $583 per year when you replace single-pane windows and between $27 and $197 a year when installing double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.
Another factor that influences the overall cost is the material you select for your frame. Aluminum frames are typically the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive because 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?
The first thing to ask yourself when planning on installing new 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 other materials, including insulation and drip edges, which increase the total cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are simpler and won’t cost as much, as they entail simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you should opt for a full-frame installation instead.
If you’re still debating which type of installation to get, you can ask your installer 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 Gaffney
In our search to find the most reliable, eco-friendly window installers in Gaffney, EcoWatch examined dozens of companies before landing on these. We’ve assessed the top window replacement companies in Gaffney mostly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Since this is a guide for Gaffney, we paid more attention to companies that cover the city. There are other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Gaffney.
Work Quality
We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company on this list to ensure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have nice feedback about their experience with a certain window installation 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 try to keep costs low when possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed, windows are a hefty investment, so you’ll want to be certain that investment is protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Gaffney’s climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of Gaffney window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Gaffney, SC Window Replacement FAQs
How much does a window install cost?
The national average cost to replace a window is about $600 but can range from $200 to $1,200, depending on several factors. The price is usually influenced by the type and material of the window, the size of the window and the location of your property. Also, remember 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 affected 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 you install your own windows?
Even though you can install your own windows, doing so is time-consuming and requires a lot of handiness. Hiring a professional can help guarantee that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.
How long does window installation usually take?
Each window takes about 30 minutes to install depending on the type of window. However, the window installation can be a two-day job — or more — if you have a lot of windows that must be installed.
