Stop Leaks at the Source
TISW CORP specializes in window and door waterproofing, professional caulking, and targeted leak repair for homes, condos, and commercial buildings across Miami. Coastal conditions, wind-driven rain, and sun exposure wear down perimeter seals over time. Our job is to find the problem quickly, fix it correctly, and protect your property from future water intrusion.
Window and Door Waterproofing
A watertight opening starts with a clean substrate and the right sealant system. We remove failed caulking, prep the surface, verify proper weeps and flashing, and reinstall coastal-grade sealants at frames, corners, sills, and headers. For sliding and terrace doors, we check thresholds, tracks, and pans, then correct gaps that allow wind-driven rain to enter.
Professional Caulking and Sealant Replacement
Perimeter seals lose elasticity as they age. To maintain performance, windows should be resealed every 5 to 7 years, depending on exposure. Our technicians use premium, UV-stable sealants and proper tooling techniques to deliver smooth, long-lasting joints that resist cracking, shrinking, and bond failure.
Leak Detection and Water Testing
We combine visual inspection with targeted water testing to confirm the source of a leak before any repair. You receive photos, findings, and a clear scope of work so you can approve the right fix with confidence. Documentation can be provided for property managers, HOAs, and insurers.
Stucco Rehabilitation and Perimeter Repair
When water intrusion has damaged the façade, we perform localized stucco rehabilitation around the opening. This restores structural integrity, improves adhesion for new sealant, and refreshes the exterior finish for a clean, uniform look.
