Air Sealing Services in Winter Springs, FL

August 1, 2025

Air sealing services tackle a problem that’s invisible but very real—air leaks. These leaks let conditioned air escape and outside air get in, and your HVAC system has to work harder. The result is hot and cold spots, higher energy bills, and uncomfortable indoor air. By sealing those cracks, gaps, and penetrations, experts create a tighter, more efficient envelope around your home.


So, how often should you have to consider the service? Every few years, especially if your insulation is old or if you just moved into an older home.


Most of the experts offering this service also do insulation upgrades, duct sealing, solar attic fans, and even rodent exclusion – services that often go hand-in-hand with air sealing to improve overall performance. Removing old insulation? That’s another key part many pros do during the same project window.


Finally, what makes a contractor worth trusting? Look for someone who combines experience with clear communication. Someone who explains why a leak matters and shows you the thermal imaging proof. Professionals who give you a full building-performance view, not just a surface fix, will always stand out.


At Capstone Insulation, we take pride in helping homeowners throughout Winter Springs create more efficient, comfortable, and healthier living spaces. With over a decade of experience serving Central Florida, we have fine-tuned our air sealing services to address the distinct challenges of our region’s climate and residential construction.

Great service and crew including Derek, James, and Michael. Their ability to insulate and seal properly resulted in a 15 percent increased air seal and insulation throughout the home - which will help our costs on both extremely hot and cold days plus level out temperatures in all our rooms. Highly recommend!

The contaminants, such as pollen or molds, can severely affect the indoor air quality. While there are various sources of indoor air pollution, the aim is to prevent as many contaminants from coming inside as possible. Gaps can allow even pests to enter your home, which can severely impact the fresh air inside.
