Duct Sealing Services

What is Aeroseal Duct Sealing?

Aeroseal duct sealing is an automated technology for sealing leaks in ductwork in both residential and commercial buildings. Using a patented, non-toxic aerosol sealant, the process pressurizes duct systems, driving sealant particles directly to leaks to seal them from the inside without coating the entire duct. The process pressurizes duct systems, driving sealant particles precisely to leaks, sealing them from the inside out without coating the entire duct interior.

Our advanced formula is very low tack, ensuring it only deposits where needed and maintains duct integrity.

Monitored in real-time for coverage and effectiveness, this technology improves HVAC efficiency, air quality, and comfort. Suitable for both new constructions and retrofits, it precisely meets any duct sealing requirement.

This is Our Team Performing a Clean and Seal

Here is a real aeroseal report from one of our clients showing the before and after results. Instead of replacing their aging AC system, our client chose duct cleaning and sealing—and the results were immediate. By removing years of buildup and sealing air leaks, their system could finally deliver air efficiently, reducing strain and improving overall performance. They started with 34% leakage so their 4 ton A/C was performing like a 2.5 ton A/C! The outcome: better comfort throughout the home, a noticeable drop in monthly energy bills, and thousands saved by extending the life of their existing AC system. Real aeroseal duct report
