Wahl Construction Co. provides specialized joint sealant application services that enhance building safety, sound isolation, and energy efficiency through professional fire and acoustic caulking. Our certified technicians precisely apply appropriate sealants to penetrations, perimeters, and joints throughout commercial structures, ensuring code compliance while creating effective barriers against fire, smoke, sound transmission, and air infiltration.

What We Offer
Comprehensive Fire Protection
Our fire-rated sealant applications establish critical defensive barriers that help contain flames, smoke, and toxic gases within designated compartments during a fire event. We meticulously seal wall penetrations, floor-to-wall joints, and construction gaps with properly rated materials, creating continuous protection that maintains the integrity of fire-rated assemblies and provides crucial evacuation time while meeting stringent building code requirements.
Advanced Acoustic Solutions
We implement specialized acoustic sealant systems that significantly reduce sound transmission between spaces by eliminating flanking paths through construction gaps. Our sound-rated caulking applications effectively seal perimeters, joints, and penetrations with flexible materials that absorb vibration and block airborne noise, enhancing occupant comfort and privacy while helping commercial spaces achieve specific Sound Transmission Class (STC) ratings.
Inspection-Ready Installation
Our technicians document and install joint sealants according to tested and approved assemblies, ensuring your building passes critical inspections. We maintain detailed records of application locations, product specifications, and installation methods, providing verification that all penetrations and joints are properly sealed according to UL listings, ASTM standards, and local building codes—giving building owners and fire marshals confidence in your structure's safety systems.
