How Installing Energy-Efficient Windows in Gastonia Saves You Money
When you switch to energy-efficient windows, you may see a few perks, such as:
- Save on electricity bills: The Department of Energy estimates that heat gained or lost via windows accounts for about 25-30% of residential energy use. Upgrading to energy-efficient windows can help reduce that number, which helps you save $343 a year on your bills.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help raise the value of your house if you decide to sell.
- Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 345 pounds.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Gastonia
When looking into window installation, each company offers different services and costs. Let’s take a look at some typical costs and services.
How Much Do New Windows Cost?
Though the national average cost of replacing one window is about $600, it can range anywhere from $200 to $1,200. But costs will vary considerably depending on the current condition of your home, your location, the quality of your products and the number of windows you need. A lot of window companies also offer door installations and other add-ons like shutters, baths, coating and more. These extra services will increase your overall project costs.
Bear in mind that energy-efficient windows may come at a higher price tag, but Energy Star estimates the upgrade will save you between $101 and $583 a year when installing single-pane windows and between $27 and $197 per year when you replace double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.
Something else that affects the total cost is the material you pick for your frame. Aluminum frames are typically the least pricey and are sturdy and relatively maintenance-free, 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 as well and cost somewhere between the other two.
What Services do Window Installers Offer?
In regard to window installations, there are generally two kinds that your provider will offer: full-frame and pocket installations.
A full-frame installation is a replacement of the total window. This service involves taking out the old window, the sill, and the exterior and interior trim. It can also involve extra materials, such as insulation and drip edges, which raise the total cost of the project. It’s also worth noting that it’s not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are simpler and won’t carry as large a bill because they involve merely replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.
Your window installation company can help you figure out which type of installation you need.

How We Choose the Best Window Installers in Gastonia
EcoWatch reviews are different from other reviews because we’re examining these companies through a sustainability lens. We’ve decided to evaluate the top window installers in Gastonia primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Because this is a guide for Gastonia, we only included companies that cover the city. There are certainly reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Gastonia.
Work Quality
We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each company on this list to ensure its contractors are well-qualified and that the company has received 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 positive feedback about their service from a certain window installation company, you won’t see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window installers may not provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. That’s why window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a proven track record in the industry. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.

When is the best time of year to replace windows?
Replacement windows can be installed at any time, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into your house, so the temperature outside isn’t necessarily a big factor. What’s more important than the temperature is that the weather should be dry.
