How Installing Energy-Efficient Windows in Lake Mary Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here are more details about how upgrading your windows could benefit you:
- Protect your investment: When you have an older home, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Lake Mary, that’s about 390 pounds per year on average.
- Save on power bills: The Department of Energy estimates that heat gained or lost via windows accounts for about 25-30% of household energy use. Installing energy-efficient windows can help lower that number, which helps you save some money on your bills.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
Estimated Cost of Window Replacement in Lake Mary
When considering window installation, each company provides different services and costs. Let’s take a look at some average costs and services.
How Much Do New Windows Cost?
Generally, Lake Mary homeowners can anticipate their replacement window installations to range from $250 to $1,200. The average cost sits at approximately $600. These numbers vary depending on specific characteristics of your installation, like the location of your home, size, material, type, number of windows and more.
It’s also worth keeping in mind that energy-efficient windows will almost always cost more initially, but Energy Star estimates that switching out the windows on your Lake Mary home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you’ll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Costs will also vary depending on the material of your frame. Aluminum frames have the lowest price. They’re sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
Generally, there are two kinds of window installation services you can get: full-frame and pocket installations.
Full-frame installations are usually recommended when you want to change the style of your windows or your window has significant rot or deterioration. With this service, your professionals will replace the full window, including the frame, sill and trim. Pocket installations are simpler and won’t carry as large a bill because they entail simply replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.
If you’re still debating which kind of installation you should get, you can talk to your provider and get their recommendation. The decision mostly is influenced by how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Lake Mary
In our search to make your home improvements easier and more eco-friendly in Lake Mary, the EcoWatch Reviews team evaluated dozens of companies before landing on these. Along with energy efficiency, we analyzed window companies all across the state and ranked them based on the following methodology:
Service Area
Since this is a guide for Lake Mary, we gave more points to companies that provide services to the city. There are certainly other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Lake Mary.
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 company on this list to ensure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If the majority of customers don’t have positive feedback about their experience with a certain window installation company, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window companies won’t always provide the highest quality service. Still, we want to make sure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a proven track record in the industry. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Lake Mary, FL Window Replacement FAQs
What is the average cost to install windows in a home?
The typical cost of replacing a window can range from $450 to $650. There are many factors that influence the cost, such as your property’s location, how energy-efficient the windows are, the materials used in designing the windows, the number of windows, local labor costs and styles and sizes of windows.
Which type of window is the best?
Generally, double-pane windows will be 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 get the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — this means they’re certified energy-efficient by the U.S. Department of Energy.
Do I really need to use a window installation company?
Unless you’re handy and have all the tools you need to replace your own windows, we recommend hiring a professional. The window installation process is complicated and can take anywhere from four to six hours for a single window. Although it’s tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and much safer alternative.
What time of year is a good time to replace my windows?
While you can install windows any time of year, warmer weather is generally better for replacing windows. Additionally, the weather should be dry, as rain can make the installation more difficult.
How often do you need 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 be in need of replacement.
