Sealants and expansion joints are a building's first line of defense against water infiltration, and among the first components to fail. Cracked, shrunken, or missing sealant lets water into wall assemblies and parking structures, while worn expansion joints can no longer accommodate the thermal movement they were designed for.

Why Sealants and Joints Fail

• UV exposure and temperature cycling break down sealant elasticity over time.
• Improper original installation or incompatible materials shorten service life significantly.
• Ponding water and debris accelerate joint deterioration in horizontal applications.
• Movement beyond a joint's designed range tears sealant away from the substrate.

Where Expansion Joints Matter Most

• Facade control joints separating masonry panels and precast sections.
• Curtain wall perimeters and window-to-wall transitions.
• Parking deck expansion joints subject to constant vehicle loading and thermal movement.
• Plaza and terrace joints exposed to standing water and freeze-thaw cycling.

Our Installation Process

• Removing all failed sealant and joint material back to a clean, sound substrate.
• Selecting joint systems and sealant chemistry engineered for the specific application and exposure.
• Installing backer rod and sealant to the correct width-to-depth ratio for long-term performance.
• Testing and inspecting completed joints before close-out.

Products and Materials

We work with silicone, polyurethane, and hybrid sealant systems, along with pre-formed and poured expansion joint systems rated for long-term UV exposure and heavy traffic, matched to each project's performance requirements.
