How Installing Energy-Efficient Windows in Greenville Saves You Money

There are several benefits of upgrading to energy-efficient windows. Some reasons you may want to consider making the change are the following:

• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Save on power bills: After you switch to energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll need less energy to heat or cool your home.
• Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, particularly if your home is on the older side.

Estimated Cost of Window Replacement in Greenville

When looking into window installation, each company provides different services and costs. Let’s take a look at some typical costs and services.

How Much Do New Windows Cost?

Even though the average cost of replacing a single window is about $600, it can range from $200 to $1,200. Costs will vary considerably based on your location, the number of windows you need, the current condition of your home and the quality of your products. A lot of window companies also offer door installations and other add-ons like shutters, baths, coating and more. Additional services will increase your overall project costs.

Keep in mind that energy-efficient windows may cost more, but Energy Star estimates the upgrade will save you between $101 and $583 per year when installing single-pane windows and between $27 and $197 per year when installing double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.

Another factor that influences the total cost is the material of the frame you choose. Aluminum frames are typically the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

The first step when considering a window replacement is to figure out whether you want a full-frame or pocket installation.

A full-frame installation is a replacement of the total window. This service involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve other materials, like insulation and drip edges, which raise the overall cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. A pocket installation involves replacing a window without removing the complete frame, which is generally cheaper than a full-frame installation.

If you’re unsure which type of window installation service you need, your installer should be able to assist you. In general, the decision is influenced by 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 Greenville

In our hunt to find the most reliable, eco-friendly window installers in Greenville, the EcoWatch Reviews team chose the above companies as the top window installation companies in the city. Along with energy efficiency, we reviewed window companies all across the state and assigned rankings using the following methodology:

Service Area

Because this is a guide for Greenville, we paid more attention to companies that serve the city. There are certainly other reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Greenville.

Work Quality

We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer featured in our guide to ensure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another super important review factor. If the majority of customers don’t have positive feedback about their service from a certain company, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: similar to most services, cheap window companies won’t always provide the highest quality service. Still, we want to make sure we’re highlighting companies that provide a variety of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a good track record in the industry. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
