How Installing Energy-Efficient Windows in St. Simons Saves You Money
There are quite a few benefits of switching to energy-efficient windows. Some reasons you may want to consider making the switch include the following:
- Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Switching to energy-efficient models can help decrease that number, therefore saving you about 12% more on your bills.
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In St. Simons, that’s about 476 pounds per year on average.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, particularly if you have an older home.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
Estimated Cost of Window Replacement in St. Simons
When researching window installation, each company offers different services and prices. Let’s take a look at some typical costs and services.
How Much Do New Windows Cost?
According to our research, the typical cost of installing a single window is around $600. However, window installation costs can range from $200 to $1,200 a window. This is because the cost of window installations depend on a variety of factors specific to your home, such as the size, material and number of windows you need to replace, as well as the location of your property.
Keep 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 installing double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.
The cost of your window installation will also vary based on the kind of material you choose for the frames. Wood windows are usually 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 planning a window installation is: Should you get a full-frame installation or a pocket installation?
Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has significant deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are simpler and won’t carry as large a bill, but you can’t do this type of installment if you have any pre-existing rot or water damage.
If you’re hiring a reputable window installation company, your company will be able to recommend the best type for your project. In St. Simons, the decision will mostly be based on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in St. Simons
In our search to make your home improvements easier and more eco-friendly in St. Simons, the EcoWatch Reviews team landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we evaluated each installer and assigned rankings 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 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
When choosing new windows, the quality and range of services often plays just as important of a role in insulation and performance as the brand you choose. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another very important review factor. If most customers don’t have positive feedback about their service from a certain window installation company, you won’t see it featured on EcoWatch.
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 points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed previously, windows are a substantial investment, so you’ll want to make sure that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of St. Simons’s climate, homeowners need to be wary of low efficiency, water damage and rot. 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
How much should a window install cost?
The typical cost of installing a window ranges from $450 to $650. There are a variety of factors that influence how much it costs, which include styles and sizes of windows, the number of windows, local labor costs, your property’s location, how energy-efficient the windows are and the materials used in designing the windows.
What are the most common kinds of replacement windows?
There are various kinds of windows you can get for your home, including awning windows, bay windows, picture windows, double-hung and single-hung windows, slider windows, transom windows and casement windows.
Can you install your own windows?
If you’re handy and have experience with installing a replacement window, it’s possible to install your own windows. However, if you don’t have the time or skills, we recommend getting a professional to do it for you.
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. 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 the home, so the temperature outside doesn’t necessarily matter that much. What’s most important is that the weather should be dry.
