How Installing Energy-Efficient Windows in Lake Mary Saves You Money
When you upgrade to energy-efficient windows, you may see several benefits, including:
- Save on energy bills: Once you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% since you'll use less energy to heat or cool your home.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- More efficient energy use in your home: Because the summers can get pretty hot in Lake Mary, homeowners usually depend on their air conditioner during that time. Energy-efficient windows cut back on how much cool air is lost through your windows, making it easier to keep your house cool.
Estimated Cost of Window Replacement in Lake Mary
Each window replacement company provides varying services and has different price points based on a few factors.
How Much Do New Windows Cost?
Even though the average to install a single window is about $600, it can range anywhere from $200 to $1,200. Costs will vary considerably based on the quality of your products, the number of windows you need, your location and the current condition of your home. Many window companies also offer door installations and other add-ons like shutters, baths, coating and more. Additional services will increase overall project costs.
Whether or not you want to install energy-efficient windows is another factor that will influence the cost. These will typically cost more than other windows, but on the other hand, you can save about $403 a year on your energy bills in Lake Mary.
We advise getting free quotes from multiple window installers to find the one that works best for your budget.
What Services do Window Installers Offer?
When it comes to window installations, there are typically two kinds that your provider will offer: full-frame and pocket installations.
A full-frame installation is a replacement of the full window. It involves taking out the old window, the sill, and the exterior and interior trim. It can also involve other materials, such as insulation and drip edges, which raise the overall cost of the project. It's also worth noting that you may have to touch up the paint around the window after a full-frame installation. A pocket installation entails replacing a window without taking out the complete frame, which is generally cheaper than a full-frame installation.
If you're unsure which window installation service you should get, your installer can help you out. Generally, the choice is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Lake Mary
EcoWatch differs from other reviewers since we evaluate these companies through a sustainability lens. We've evaluated the top window replacement companies in Lake Mary mostly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows have been shown to lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve the Lake Mary area so you can find the best window installation company near you.
Work Quality
We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer on this list to make sure its contractors are well-qualified and that the company has gotten lots 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 nice things to say about their experience with a certain installer, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window installation companies won't always provide the most quality service. Still, we want to ensure we're highlighting companies that offer a spectrum 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 give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Lake Mary's climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Lake Mary window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Lake Mary, FL Window Replacement FAQs
How much should window installation cost?
The average cost of installing one window can range between $450 and $650. There are many factors that influence the cost, including local labor costs, the materials used in designing the windows, your property's location, the number of windows, how energy-efficient the windows are and styles and sizes of windows.
Which type of window should I get?
A window's energy efficiency is influenced by a number of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.
What services do window replacement companies provide?
Window installers travel to your property to remove your old windows and replace them with new ones. Some providers install products distributed by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is finished.
When is the best time of year to replace windows?
Replacement windows can be installed at any time, but warmer weather is typically better. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your home, so the temperature outside doesn't necessarily matter that much. What's more important than the temperature is that the weather should be dry.
When is it time to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Other than 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.
