Welcome to West Coast Firestopping & Expansion Joints

Our Mission

At West Coast Firestopping, Inc. we provide you with peace of mind that ALL of your firestop needs will be met. We provide each project with a professional, experienced work team who understands proper installation of tested UL firestop systems.

Anyone can put “red caulking” into an opening. The West Coast team will make sure the correct caulking is installed around the right penetration.
