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.

Window and Door Waterproofing
Frequently Asked Questions
You’ll find answers to common questions about waterproofing, sealing, and caulking services for windows and doors.
How often should windows be resealed
Impact systems use laminated glass, reinforced frames, and Miami-Dade compliant hardware to resist wind-borne debris and pressure changes during storms. They also add security, reduce noise, and can improve energy performance.
Are your products Miami-Dade NOA and Florida Product Approval compliant?
Yes. We install hurricane impact windows, impact doors, and storefront glass that meet or exceed Miami-Dade and Florida Building Code requirements. We provide all approvals and documentation for permits, HOAs, and insurers.
Do you handle permitting, inspections, and HOA approvals?
Yes. TISW CORP provides an end-to-end process that includes site measurement, engineering coordination, permitting, installation by in-house crews, and final inspections. We also support HOA submissions when required.
How long does installation take?
Timelines vary by scope and municipality. After measurements and permits, most single-family home projects install in a few days. Larger storefronts and multi-unit jobs require phased scheduling. We share a clear timeline before work begins.
Will impact windows and doors help with noise and energy costs?
Laminated glass reduces outside noise and, paired with low-E options and proper installation, can help manage heat gain for better comfort and potential energy savings. Results depend on product selection and exposure.
What areas and property types do you serve?
We focus on Coral Gables, South Miami, Pinecrest, Miami Beach, Surfside, Bal Harbour, Sunny Isles, Brickell, Coconut Grove, East Kendall, and nearby coastal neighborhoods. We work on single-family homes, luxury condos, and commercial storefronts.
