Our caulking and spray foam crews deliver precise, professional installation that helps commercial buildings stay energy-efficient, weather-tight, and code-compliant. From expansion joint sealants to thermal and moisture barriers, Miles-McClellan provides detailed, schedule-sensitive work that ties together other trades and supports the integrity of the building. Our installations prevent water intrusion, control air leakage, and support long-term durability.
We install interior and exterior caulking for expansion joints, perimeter windows and doors, masonry control joints, and dissimilar material transitions.
We apply spray foam to insulate hard-to-reach cavities, wall systems, and roof decks. Spray foam improves thermal performance, adds structural rigidity, and forms an air and vapor barrier in one application.
Miles-McClellan coordinates closely with other trades to seal around penetrations, MEP sleeves, curtain wall interfaces, and weather barrier transitions to eliminate air leaks and moisture paths that could compromise building performance.
We install UL-rated fire caulking in rated walls, joints, and penetrations to help meet life safety codes and inspection requirements. That includes coordination with MEP trades to ensure complete coverage.

This 80,000 sq ft renovation and addition to an active school campus included new classrooms, science labs, and a state-of-the-art library and media center.
Miles-McClellan helps deliver results to keep your building protected from air and water intrusion while supporting long-term performance.
