How Installing Energy-Efficient Windows in St. Simons Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here's more information on how upgrading your windows could help you:
- More efficient energy usage in your home: In St. Simons where the winters can be very chilly, energy-efficient windows reduce how much heat is lost through your windows, making it easier to keep your house warm.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
- Save on power bills: After you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% because you'll require less energy to heat or cool your house.
- Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.
Estimated Cost of Window Replacement in St. Simons
Let's take a look at the cost of installing new windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
Although the average of replacing a single window is about $600, it can range anywhere from $200 to $1,200. How much it will cost you varies based on several factors, including number of windows, type, the location of your home, material, size and more.
Bear in mind that energy-efficient windows may cost more upfront, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.
Another factor that affects the total cost is the material you choose for your frame. Aluminum frames are usually the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames cost the most, 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 general, there are two types of window replacement services you can get: full-frame and pocket installations.
Full-frame installations are usually done when you want a new style or your window has a lot of rot. With this service, your installers will replace the total window, including the frame, sill and trim. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.
If you're still trying to decide which kind of installation you should get, you can talk to your provider and get their recommendation. The choice mostly is influenced by how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in St. Simons
EcoWatch reviews differ from most reviews, as we evaluate these companies through a sustainability lens. Along with energy efficiency, we reviewed each installer and ranked them using the following methodology:
Service Area
Since this is a guide for St. Simons, we gave more points to companies that cover 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 St. Simons.
Work Quality
We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each installer on this list to make sure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the highest rates of customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including warranty, professionalism, cost, quality of parts, quality of installation and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of St. Simons' climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of St. Simons window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
St. Simons, GA Window Replacement FAQs
What is the typical cost to install new windows?
The national average cost to replace one window is about $600 but can range between $200 and $1,200, depending on a few different factors. The price is usually dependent on the size of the window, the location of your property and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What kind of window is the most energy-efficient?
A window's energy efficiency is influenced by several factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.
When do I have to use a window installation company?
Unless you have experience with home improvement projects and have the tools needed to replace your own windows, we recommend hiring a professional. The process of installing windows is complicated and can take anywhere from four to six hours for one window. Although it's tempting to try to save money by doing it yourself, hiring a company is a faster, more efficient and safer option.
When is the best time of year to replace windows?
Replacement windows can be installed at any time, but autumn might be the best season. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into the house, so the temperature outside doesn't necessarily matter that much. What's most important is that the weather should be dry.
