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• Protect your investment: When you have an older home, your windows could also be outdated or leaky.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.
