How Installing Energy-Efficient Windows in Wilmington Island Saves You Money
Switching to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here are more details about how upgrading your windows could help you:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
- Save on power bills: The Department of Energy estimates that heat gained or lost via windows accounts for about 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.
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Wilmington Island
Each window installer provides varying services and has different price points based on several factors.
How Much Do New Windows Cost?
According to our research, the national average cost of replacing a single window is around $600. However, window installation costs can range from $200 to $1,200 a window. This is because window installations are based on several factors specific to your home, including the size, material and number of windows you need to install, as well as the location of your property.
It’s also worth keeping in mind that energy-efficient windows will cost more initially, but Energy Star estimates that switching out the windows on your Wilmington Island home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you’ll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
The cost of your window installation will also vary based on the type of material you choose for the frames. Wood windows are typically the most expensive, although it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
The first question to ask yourself when getting new windows is: Do you need a full-frame installation or a pocket installation?
Full-frame installations are necessary when you want to change the style of your windows or your window has a lot of rot. With this service, your installers will replace the complete window, including the frame, sill and trim. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations more simple and affordable. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.
If you’re still debating which type of installation you should get, you can ask your provider and get their recommendation. The decision mostly is influenced by how old the frames are and if there’s any damage present.

How We Choose the Best Window Installers in Wilmington Island
In our hunt to find the most reliable, eco-friendly window installers in Wilmington Island, the EcoWatch Reviews team evaluated dozens of companies before landing on these. We’ve evaluated the best window replacement companies in Wilmington Island mainly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows can reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Because this is a guide for Wilmington Island, we gave more points to companies that provide services to the city. There are other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Wilmington Island.
Work Quality
We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer featured on this list to make sure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent online reviews to determine the companies with the most consistent customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including quality of installation, quality of parts, warranty, cost, professionalism and more.
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 make sure we’re highlighting companies that offer a wide range 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 protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Wilmington Island’s climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of Wilmington Island window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
