20 Best Window Companies in Greenwood, SC (2025 Reviews)

How Installing Energy-Efficient Windows in Greenwood Saves You Money

Energy-efficient windows can offer benefits in several ways. Here are a few reasons you may want to consider making the switch:

• Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
• Save money on electricity bills: Switching to energy-efficient windows lowers your energy bills by about 12% since you need less energy.
• Reduce your carbon footprint: In Greenwood, you can lower your indirect greenhouse gas emissions by about 415 pounds per year once you switch to energy-efficient windows.

Estimated Cost of Window Replacement in Greenwood

Windows come in different styles, purposes and shapes, so costs and services will vary greatly based on several factors. Below, we describe the typical cost and services that you can get from window replacement companies.

How Much Do New Windows Cost?

According to our market research, the national average cost of installing a single window is around $600. However, window installation costs can range from $200 to $1,200 a window. But costs will differ considerably depending on your location, the number of windows you need, the quality of your products and the current condition of your home. Many window companies also offer replacement door installations and other add-ons like baths, shutters, coating and more. These extra services will increase your overall project costs.

Whether or not you want energy-efficient windows is another factor that will determine the cost. These will almost always cost more than other windows, but on the other hand, you can save about $396 a year on your energy bills in Greenwood.

Requesting free quotes from multiple companies is the best way to find out which one is right for you.

What Services do Window Installers Offer?

In regard to window installations, in general there are two kinds that your installer will offer: full-frame and pocket installations.

Full-frame installations entail replacing the complete window, including the trim, sill and frame. Full-frame installations are necessary when you want to change the style of your windows or your window has noticeable damage or rot. Because these installations are more involved, they will increase overall costs. Pocket installations are simpler and won’t cost as much, as 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.

Your window installation company should be able to help you decide what’s best for your needs. In Greenwood, the decision will mostly depend on how old your windows are and if there’s any damage. Wood can decay if it’s not maintained properly over the years, so it’s a good idea to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Greenwood

In our search to make your home improvements easier and more eco-friendly in Greenwood, the EcoWatch team chose the above companies as the top window installation companies in the city. We have reviewed the top window replacement companies in Greenwood mainly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Since this is a guide for Greenwood, we paid more attention to companies that provide services to the city. There are certainly other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Greenwood.

Work Quality

When picking new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the type of window you opt for. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another very important review factor. 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

This one is a give-and-take: as with 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 provide 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 that have lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Due to Greenwood’s climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Greenwood window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
