Cracked or moldy caulk around a tub, sink, or window is not just cosmetic in Miami's humidity — it is where water gets behind tile and drywall and starts real damage. We strip out the old caulk completely, clean the surface, and lay a fresh, mildew-resistant seal that actually holds.

Miami's humidity keeps bathroom surfaces damp longer than drier climates, which speeds up mold growth in ordinary caulk. We use mildew-resistant, silicone-based caulk in wet areas to slow it down significantly.
It is a real problem — once caulk separates from the surface, water gets behind tile, tubs, and countertops and can cause hidden damage long before it is visible. Resealing early is much cheaper than the repair that follows if it is ignored.
