Building Envelope Risks
Protect Your Building From Water & Structural Movement
Sealants and expansion joints play a critical role in maintaining a weather-tight building envelope. As buildings naturally expand, contract, and settle, properly designed joint systems prevent moisture intrusion, reduce structural stress, and help avoid costly repairs.

SUPPORT & GUIDANCE
Your Sealant & Expansion Joint Questions
Our team of commercial building specialists is here to help you navigate your joint sealing and waterproofing needs. Have a specific technical question about your property? Reach out to our experts directly.
What are expansion joints?
Expansion joints are specifically designed gaps in a building's structure that accommodate natural expansion, contraction, and settlement, preventing stress cracks and structural damage.
When should commercial sealants be replaced?
Commercial sealants should typically be replaced every 7 to 10 years, depending on UV exposure, joint movement, and material quality. Regular inspections are recommended to catch failures early.
How do failed sealants affect a building?
Failed sealants allow water intrusion, which can lead to interior damage, mold growth, structural deterioration, and costly concrete spalling or rebar corrosion over time.
Do you work on occupied commercial properties?
Yes, we specialize in minimally disruptive installations for occupied commercial properties, ensuring absolute safety and clear communication with tenants and property managers throughout the project.
What sealant materials do you recommend?
We recommend premium, manufacturer-approved silicone and polyurethane sealants designed specifically for high-movement commercial joints, tailored to your building's exact specifications.
