ENGINEERED SYSTEMS FOR MOVEMENT AND MOISTURE CONTROL

Sealants & Expansion Joint Systems

Sealants and expansion joints are functional components of the building envelope, not surface-level finishes. These systems are designed to absorb movement, protect material transitions, and prevent water intrusion at some of the most failure-prone locations on a structure.

GKW Restoration approaches sealant and joint work with a system-based mindset, considering substrate conditions, joint geometry, material compatibility, and anticipated movement to ensure lasting performance.

Removal & Replacement

ADDRESSING FAILED OR DETERIORATED JOINT SYSTEMS

Aging materials, improper installation, and movement beyond design limits commonly lead to sealant failure. GKW Restoration provides complete sealant removal and replacement services, restoring joint integrity through proper surface preparation and installation methods aligned with current performance standards.

Common Applications

WHERE SEALANT AND JOINT SYSTEMS ARE USED

Masonry and concrete control joints

Window and door perimeters

Expansion joints in walls and structures

Transitions between dissimilar materials

Why GKW Restoration

Sealants and expansion joints fail most often when treated as maintenance items instead of engineered systems. GKW Restoration’s understanding of building movement and envelope behavior ensures joint systems that protect the structure over time.

Sealants & Expansion Joint FAQs

COMMON QUESTIONS ABOUT JOINT PERFORMANCE AND DURABILITY

What causes sealant and expansion joint failures?

Failures are often caused by improper joint design, poor surface preparation, incompatible materials, UV exposure, or building movement exceeding the original design limits.

How often should sealants be replaced?

Service life varies by material and exposure, but many sealant systems require evaluation every 7–15 years. Regular inspections help identify failures before water intrusion occurs.

What is the difference between expansion joints and control joints?

Expansion joints accommodate significant building movement, while control joints manage shrinkage cracking in concrete or masonry. Both require different detailing and materials.

Can sealants be replaced without damaging surrounding materials?

Yes. Proper removal techniques and substrate preparation allow sealants to be replaced without damaging adjacent masonry, concrete, or finishes.

Are sealant systems part of the building envelope?

Yes. Sealants are critical envelope components that maintain continuity at transitions and prevent moisture intrusion.
