Joint Sealant & Caulking
Sealants and caulking are the first line of defense in your building’s exterior envelope. They seal the joints, seams, and penetrations where water, air, and humidity try to sneak inside.
Joint sealants are a key component of above-grade waterproofing. They work alongside coatings, flashing, and drainage systems to keep water where it belongs — outside the building.
When sealants fail, buildings fail.
On the Gulf Coast, failed sealants can lead to:
-
Water leaks during storms
-
Mold and mildew inside walls
-
Rusting window frames and fasteners
-
Peeling interior finishes
-
Reduced HVAC efficiency
-
Structural damage over time
Salt air, UV exposure, temperature swings, and high humidity cause sealants to dry out, crack, or pull away. Once that happens, it’s only a matter of time before moisture makes its way in.
Sealants & Joint Caulking FAQ
Q: How long do sealants last?
A: Depending on the chemistry and environment, 10–20 years is typical. Coastal UV and salt exposure reduce lifespan, so regular inspections are smart.
Q: Can I just add new caulking on top of old?
A: Not recommended. Proper adhesion requires removing failed material and prepping joints.
Q: Is this the same as painter’s caulk?
A: No. Painter’s caulk is cosmetic. We use building envelope sealants designed for movement, adhesion, and weather exposure.
