Professional caulking and sealing restores the watertight and airtight barriers around your home's most vulnerable joints. Exterior caulking around windows, doors, siding gaps, and penetrations prevents water intrusion and air leaks. Interior caulking around bathtubs, showers, sinks, backsplashes, and baseboards prevents moisture damage and mold growth. We use silicone caulk for wet areas (bathrooms, kitchens), paintable acrylic-latex for trim and baseboards, and polyurethane for exterior joints that need flexibility and weather resistance. Old, cracked, or moldy caulk is completely removed before applying fresh beads.

Paso Robles is located in San Luis Obispo County (Central Coast). Inland wine country town with hot summers, historic downtown, and newer suburban growth. The local utility provider is PG&E.

Caulking & Sealing in Paso Robles — FAQ

How much does professional caulking cost?+

Professional caulking runs $150-$400 for a typical bathroom (tub/shower surround, sink, toilet base) and $200-$500 for exterior window and door caulking in the Sacramento area. Whole-house interior and exterior caulking ranges from $400-$900.

How often should caulking be replaced?+

Bathroom silicone caulk should be inspected annually and replaced every 3-5 years. Exterior caulk around windows and doors lasts 5-10 years depending on sun exposure. Sacramento's heat accelerates UV degradation on south- and west-facing surfaces.

What type of caulk should I use in the shower?+

Always use 100% silicone caulk in showers and tubs — it's waterproof, flexible, and mold-resistant. Never use acrylic-latex caulk in wet areas; it will crack and allow water behind the tile.
