How Installing Energy-Efficient Windows in Greenwood Saves You Money
There are quite a few perks of switching to energy-efficient windows. Some reasons you may want to consider making the change are the following:
- Reduce your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by 415 pounds per year on average.
- Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.
- Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Replacing your windows with energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.
- Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its value.
Estimated Cost of Window Replacement in Greenwood
Windows come in various shapes, styles and purposes, so costs and services will vary remarkably depending on your project. Below, we describe the average cost and services that you can get from window installers.
How Much Do New Windows Cost?
Though the national average to install one window is around $600, it can range from $200 to $1,200. How much it will cost depends on several factors, such as material, type, the location of your home, size, number of windows and more.
It's important to keep in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Greenwood homeowners $396+ a year when replacing single-pane windows.
We recommend getting free quotes from several window installers to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
The first step when considering a window installation is to decide whether you should get a full-frame or pocket installation.
Full-frame installations entail replacing the complete window, including the frame, sill and trim. Full-frame installations are necessary when you want a new style or your window has considerable damage or rot. Because full-frame installations are more involved, they will increase the total cost. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and will be less expensive, but you can't do this type of installment if you have any pre-existing rot or water damage.
If you're unsure which window installation service you need, your installer can help you out. Generally, the choice is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Greenwood
In our hunt to find the most reliable, eco-friendly window installers in Greenwood, EcoWatch evaluated many companies before landing on these. Along with energy efficiency, we reviewed window companies all across the state and assigned rankings using the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the right window installation company near you.
Work Quality
When choosing new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the type of window you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don't have good things to say about their service from 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 want 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
As discussed, windows are a serious investment, so you'll want to make sure that investment is protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Greenwood's climate, homeowners will want to mitigate low efficiency, water damage and rot. We factored in local experience to reflect the ability of Greenwood window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Greenwood, SC Window Replacement FAQs
What is the average cost to install windows?
The typical cost to install a single window can range from $450 to $650. There are a variety of factors that affect how much it costs, including the materials used in designing the windows, the number of windows, your property's location, how energy-efficient the windows are, styles and sizes of windows and local labor costs.
What type of window is the best for energy efficiency?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you'll have the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — they're certified energy-efficient by the U.S. Department of Energy.
What do window installers do?
Window installation professionals will do the entire process — from replacing your old windows with new ones to cleaning up after the installation. Additionally, some companies offer window manufacturing, customization and repairs.
How long does window installation usually take?
Each window takes about 30 minutes to install based on the type of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
Should I replace my windows all at the same time?
If you want to get more efficient windows and save money on energy costs, replacing all of your windows at the same time is the only way to see a noticeable difference. On the other hand, if you have just a few windows that are broken or drafty, you can replace just those.
