How Installing Energy-Efficient Windows in Sumter Saves You Money
When you switch to energy-efficient windows, you may see several benefits, such as:
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Sumter, that’s about 415 pounds per year on average.
- Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of energy use in your home. Switching to energy-efficient windows can help lower that amount, which helps you save some money on your bills.
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its real estate value.
- 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 Sumter
Windows come in different shapes and sizes, so costs and services will vary considerably. Here are the average costs and the primary services that you can find from the average window installation company.
How Much Do New Windows Cost?
The typical cost to install one window is about $600 but can range from $200 to $1,200. But costs will vary considerably based on the quality of your products, the number of windows you need, your location and the current condition of your home. Many window companies also offer door installations and other add-ons like baths, coating, shutters and more. These extra services will increase your overall project costs.
Whether or not you want energy-efficient windows is another factor that will affect the cost. These will usually cost more than other windows, but on the other hand, you can save about $397 a year on your energy bills in Sumter.
We advise getting free quotes from multiple window installation companies to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
The first step when planning an installation is to decide whether you need a full-frame or pocket installation.
Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has significant deterioration. Full-frame installations involve more time and labor and will increase overall costs. A pocket installation involves replacing a window within the existing frame. This means instead of tearing out the whole unit and reinstalling it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you’re not sure which window installation service you should get, your installer should be able to assist you. Typically, the decision depends 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 Sumter
In our hunt to make your home improvements easier and more eco-friendly in Sumter, the EcoWatch team chose the above companies as the best window installation companies in the city. We have reviewed the best window installation companies in Sumter primarily based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for Sumter, we only included companies that cover the city. There are certainly other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Sumter.
Work Quality
When selecting new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand you choose. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another very important review factor. If most customers don’t have positive things to say about their experience with a certain installer, it won’t be featured on EcoWatch.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers’ prices, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important. That’s why window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Sumter’s climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Sumter window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Sumter, SC Window Replacement FAQs
How much should a window install cost?
The typical cost to replace a window ranges between $450 and $650. There are a variety of factors that influence the cost, such as the materials used in designing the windows, your property’s location, the number of windows, how energy-efficient the windows are, local labor costs and styles and sizes of windows.
Which kind of window should I get?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. To be sure you’re getting the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — that means they’re certified energy-efficient by the U.S. Department of Energy.
What services do window replacement companies offer?
Window installers visit your house to remove your old windows and replace them with new ones. Some companies install products sold by other companies, whereas others install their own windows. The installer will also clean up after the installation is complete.
When is it time to replace your windows?
Windows typically last about 20 to 30 years, but anytime you notice damage on your windows, it’s a good idea to have them looked at by an expert to see if they need any repairs or replacements.
How long does window installation generally take?
Because the average installation time of a window is 30 minutes, about 16 windows can be installed in a typical 8-hour work day.
