Specialty

At American Empire Firestop Inc., we specialize in the expert application of UL-approved fire-rated systems for both residential and commercial construction projects. Our team is trained in the proper installation of intumescent firestop caulking for through penetrations in fire-rated assemblies, including mechanical, electrical, plumbing, and low-voltage systems.

In addition to firestopping, we offer a full range of sealant and specialty applications to meet modern building performance and code requirements. These include:

• Intumescent firestop coatings and caulks
• Architectural and acoustical caulking
• Floor joint and slab edge sealants
• Weatherproofing for exterior doors, windows, and joints
• Head-of-Wall and Bottom-of-Wall firestopping for CMU and drywall assemblies

Our solutions enhance both the safety and comfort of the building envelope, delivering reliable protection, sound control, and weather resistance. Whether it’s new construction, renovation, or tenant improvement work—we ensure every penetration and joint is sealed to code and built to last.

We are trusted partners on both private-sector developments and publicly funded construction projects across California. Whether we’re working with commercial developers, general contractors, or government agencies, our team approaches every job with the same core values: integrity, precision, accountability, and respect for timelines and budgets.

We understand that public works require strict adherence to prevailing wage laws, certified payroll reporting, and state-mandated safety and compliance standards. Our staff is fully trained to navigate these requirements, and we’re proudly registered with the California Department of Industrial Relations (DIR) to ensure we meet all public project qualifications.

For private developments—whether it’s new construction, tenant improvements, or multi-family housing—we provide fast, code-compliant firestop and sealant solutions that help accelerate schedules, minimize risk, and protect long-term value.

We treat every project as a partnership. From
