How Installing Energy-Efficient Windows in Gaffney Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to think about making the switch:
- Better temperature control in your home: When you live in a city like Gaffney where the summers can get very hot, you often need to depend on your air conditioner to keep your house cool. Energy-efficient windows can reduce how hard your AC needs to work to cool your home.
- Protect your investment: When you have an older home, your windows could also be outdated or damaged.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.
- Better temperature control in your home: Residing in a chilly city like Gaffney can often mean depending on your heater to keep your house cool. Energy-efficient windows can lower how hard your heating system needs to work to heat your home.
- Decrease your carbon footprint: In Gaffney, you can cut your indirect greenhouse gas emissions by about 415 pounds per year after you upgrade to energy-efficient windows.
Estimated Cost of Window Replacement in Gaffney
When looking into window installation, each company provides varying services and costs. Let's look at some average costs and services.
How Much Do New Windows Cost?
According to our market research, the typical cost of installing a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. But costs differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door replacements, which will add extra costs to your project.
It's also worth bearing in mind that energy-efficient windows will usually cost more upfront, but Energy Star predicts that switching out the windows on your Gaffney home translates to 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. The amount of money you'll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
We advise requesting free quotes from several window companies to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
There are typically two types of window replacement services: full-frame and pocket installations.
Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has significant deterioration. Full-frame installations require more time and labor and will increase overall costs. A pocket installation entails replacing a window within the existing frame. So, instead of taking out the whole window and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.
If you're unsure which window installation service you need, your installer should be able to assist 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 Gaffney
EcoWatch differs from most reviewers since we assess these companies through a sustainability lens. Along with energy efficiency, we reviewed window companies all across the state and assigned rankings using the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve Gaffney so you can find a quality window installation company near you.
Work Quality
When selecting new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand of window you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent customer feedback to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across nearly every category, including warranty, quality of installation, professionalism, cost, quality of parts and more.
Cost
This one is a give-and-take: similar to most services, cheap window installers won't always provide the most quality service. Still, we want to ensure 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 sizable investment, so you'll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Gaffney's climate, homeowners will want to mitigate water damage, rot and low efficiency. 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
What is the average cost to install new windows in a home?
The national average cost of replacing a window is around $600 but can range from $200 to $1,200, depending on a few different factors. The price is generally influenced by the type and material of the window, the size of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
Which kind of window is the best?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. To be sure you'll have the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — they're certified energy-efficient by the U.S. Department of Energy.
When should I use a window installation company?
Unless you have experience with home improvement projects and have the time to replace your own windows, we recommend hiring a professional. The process of installing windows is quite involved and can take anywhere from four to six hours for a single window. Although it's tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and much safer alternative.
Should I replace all my windows at once?
If you're upgrading your windows to save on your energy bills, replacing all your windows at once is the only way to see a noticeable difference. However, if you have only one or two windows that are damaged or drafty, you can replace just those.
