How Installing Energy-Efficient Windows in Spartanburg Saves You Money
Energy-efficient windows can provide benefits in more than one way. Here are some reasons you may want to make the switch:
- Reduce your carbon footprint: Reducing how much energy you use also lowers your carbon emissions. You could reduce it by about 415 pounds.
- Save money on energy bills: Since energy-efficient windows reduce the amount of energy needed to heat or cool your home, the switch can help you save around $372 annually on your energy bills in Spartanburg.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
- Protect your investment: If you have an older home, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help raise the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Spartanburg
Let’s go over the cost of window installation and the kinds of services you may need for your home.
How Much Do New Windows Cost?
According to our market research, the typical cost to replace a single window is about $600. However, window installation costs can range from $200 to $1,200 per window. But costs will vary considerably depending on the current condition of your home, the number of windows you need, your location and the quality of your products. A lot of window companies also offer door installations and other add-ons like shutters, coating, baths and more. These extra services will increase overall project costs.
Whether or not you want to install energy-efficient windows is another factor that will influence the cost. These will almost always cost more than other windows, but on the other hand, you can save about $372 a year on your energy bills in Spartanburg.
Asking for free quotes from multiple installers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
The first step of a window replacement is to clarify whether you should get a full-frame or pocket installation.
Full-frame installations require replacing the entire window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has significant deterioration. Full-frame installations are more involved and will increase overall costs. Pocket installations are simpler and won’t cost as much because they involve merely 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 unsure which kind of window installation service you should get, your installer should be able to assist you. Generally, the decision 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 Spartanburg
In our hunt to make your home improvements easier and more eco-friendly in Spartanburg, the EcoWatch team assessed dozens of companies before landing on these. Along with energy efficiency, we analyzed window companies all across the state and assigned rankings based on the following methodology:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installers that serve Spartanburg so you can find the right window installation company near you.
Work Quality
We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each company in our guide to ensure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If the majority of customers don’t have nice feedback about their service from a certain company, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window installation companies may not provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed, windows are a hefty investment, so you’ll want to be certain that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Spartanburg’s climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Spartanburg window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Spartanburg, SC Window Replacement FAQs
How much should window installation cost?
The average cost to install a single window can range between $450 and $650. There are many factors that affect how much it costs, which include your property’s location, styles and sizes of windows, local labor costs, the materials used in designing the windows, the number of windows and how energy-efficient the windows are.
What kind of window is the most energy-efficient?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. If you want to be sure you’re getting 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.
What do window installation companies do?
Window installation professionals travel to your property to remove your old windows and replace them with new ones. Some providers install products distributed by other companies, whereas others install their own windows. The installer will also clean up after the installation.
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, they should probably 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.
How long does it generally take to install windows?
Since the average installation time of a window is 30 minutes, around 16 windows can be installed in an 8-hour work day.
