How Installing Energy-Efficient Windows in St. Marys 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 switching out your windows could help you:
- More efficient energy use in your home: Because the winters can get very chilly in St. Marys, homeowners usually depend on their heater during that time. Energy-efficient windows decrease how much heat is lost through your windows, which makes it easier to keep your house warm.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.
- Reduce your carbon footprint: Reducing how much energy you use also lowers your carbon emissions. You could reduce it by about 476 pounds.
Estimated Cost of Window Replacement in St. Marys
When researching window installation, each company provides varying 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 average cost to replace a single window is about $600. However, window replacement costs can range from $200 to $1,200 for each window. This is because of the fact that the cost of window installations depend on several factors specific to your home, such as the size, material and number of windows you need to install, as well as where your property is located.
Bear in mind that energy-efficient windows may cost more, but Energy Star predicts 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 savings will vary depending on your local climate, energy rates and individual home characteristics.
Getting free quotes from multiple companies is the best way to find out which one will work best for your budget.
What Services do Window Installers Offer?
The first question to ask yourself when planning to replace your windows is: Should you get a full-frame installation or a pocket installation?
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 also involves extra materials, like insulation and drip edges, which increase the total cost of the project. Also worth noting: 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 cost as much because they involve simply replacing the window within its existing frame. But if the frame has any damage or rot, you may need a full-frame installation instead.
Your window installation company should be able to help you decide which type of installation you should get.

How We Choose the Best Window Installers in St. Marys
EcoWatch reviews differ from other reviews since we evaluate these companies through a sustainability lens. We have evaluated the top window installers in St. Marys mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the best window installation company near you.
Work Quality
When selecting new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand you opt for. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including quality of parts, warranty, professionalism, quality of installation, cost and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important. That's why window installation companies with 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 years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
St. Marys, GA Window Replacement FAQs
How much should window installation cost?
The national average cost to install a window is about $600 but can range from $200 to $1,200, depending on a few different factors. The price is usually influenced by the location of your property, the type and material of the window and the size of the window. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What are the most common types of replacement windows?
The most common types of windows for homes include: casement windows, slider windows, picture windows, double-hung and single-hung windows, transom windows, bay windows and awning windows.
Do you really need to use a window installation company?
You should hire a window installation company whenever you need new windows. Installing windows is a complicated process that can be difficult and time-consuming, so it's best left to the professionals.
How do you know it's time to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to open or close, they may need to be replaced.
Should I replace all my windows at the same time?
If your windows are greater than 20 years old, you most likely need to replace all of them. By that point, they are typically less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
