How Installing Energy-Efficient Windows in Bay St. Louis Saves You Money
There are several perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch include the following:
- Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its value.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
- Save on power bills: Once you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% since you’ll need less energy to heat or cool your house.
Estimated Cost of Window Replacement in Bay St. Louis
Let’s go over the cost of installing new windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
Though the typical cost of replacing a single window is around $600, it can range from $200 to $1,200. But costs will differ significantly based on the quality of your products, the number of windows you need, your location and the current condition of your home. A lot of window companies also offer door installations and other add-ons like coating, shutters, baths and more. These extra services will increase overall project costs.
It’s also worth noting that energy-efficient windows will usually cost more initially, but Energy Star predicts that switching out the windows on your Bay St. Louis home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you’ll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Asking for free quotes from multiple providers 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 considering a window replacement is: Do you want a full-frame installation or a pocket installation?
A full-frame installation is a total window replacement. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves additional materials, such as insulation and drip edges, which raise 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 (or retrofits) involve replacing a window within its existing frame, which makes pocket installations more simple and affordable. However, if the frame has any rot or deterioration, you will likely need a full-frame installation instead.
Your window installation company should be able to help you choose which type of installation you need.

How We Choose the Best Window Installers in Bay St. Louis
The EcoWatch Reviews team is different from other reviewers, as we’re examining these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer and ranked them based on the following methodology:
Service Area
Since this is a guide for Bay St. Louis, we gave more points to companies that serve the city. There are other reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Bay St. Louis.
Work Quality
When it comes to new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the brand of window you choose. We do rate window installers higher 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 the majority of customers don’t have nice things to say about their experience with a certain window installation company, it won’t be featured on EcoWatch.
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 providers’ prices, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed previously, windows are a significant investment, so you’ll want to make sure that investment is protected. Window installation companies that have 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 installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Bay St. Louis, MS Window Replacement FAQs
What is the typical cost to install new windows in a home?
The average cost of replacing one window can range between $450 and $650. There are a variety of factors that affect how much it costs, which include how energy-efficient the windows are, styles and sizes of windows, the materials used in designing the windows, the number of windows, your property’s location and local labor costs.
Which kind of window is the best?
Generally, double-pane windows are more efficient than single-pane windows and windows that don’t open will be more efficient than windows that do. If you want to be sure you’ll have the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — that means they’re certified energy-efficient by the U.S. Department of Energy.
When do I have to use a window installation company?
You should use a window installation professional whenever you need to replace your windows. Installing windows is a involved process that can be difficult to do on your own, so it’s best left to the professionals.
How long does it take to install windows?
Because the average installation time is 30 minutes per window, around 16 windows can be installed during a typical 8-hour work day.
