Even the best insulation can't perform if conditioned air is leaking out through unsealed gaps and cracks. Air sealing is the foundation of an efficient home, and it's especially important in the older North Texas homes that were never built tight. Insulation Experts of Texas seals the leaks around windows, doors, penetrations, top plates, and ductwork that let your heated and cooled air escape.
Caulking and air sealing is one of the most affordable, highest-return improvements you can make. Done before or alongside an insulation upgrade, it stops drafts, steadies room temperatures, and helps your HVAC system run far more efficiently.
Where Homes Lose the Most Air
Hidden leaks add up fast: gaps around recessed lights and exhaust fans, plumbing and wiring penetrations, attic hatches, rim joists, and the seams around windows and doors. We find and seal these leak points so your insulation can finally do its job.
A Smart First Step in Any Efficiency Plan
Air sealing pairs naturally with attic insulation, spray foam, and ventilation upgrades. Sealing the envelope first means every other improvement works harder, which is why we so often recommend it as the starting point for older DFW homes.
Benefits of Caulking & Air Sealing
- Stops drafts and uneven room temperatures
- Lowers heating and cooling bills
- Makes your existing insulation more effective
- Reduces dust, pollen, and outdoor air infiltration
- Affordable improvement with a fast payback
- Ideal first step before insulating older homes
Frequently Asked Questions
Is air sealing worth it?
Absolutely. Air leakage is a leading cause of energy waste in North Texas homes. Sealing those leaks is one of the most cost-effective upgrades available and makes all your other insulation work better.
Should I air seal before adding insulation?
Yes, sealing the building envelope first ensures your new insulation performs at its full R-value instead of letting conditioned air leak right past it.
