Why Waterproofing Matters in Marin County

Marin County’s coastal climate, hillside terrain, and seasonal rainstorms make professional waterproofing essential for maintaining your property’s integrity. Whether you own a mid-century hillside home in Sausalito or a commercial building in San Rafael, uncontrolled moisture can lead to dry rot, mold, foundation cracks, and long-term structural damage.

At VCE, we provide licensed, targeted waterproofing solutions for both residential and commercial buildings — ensuring your home or business stays safe, dry, and structurally sound.

Whole-Building Envelope Protection

Waterproofing is more than just sealing cracks — it’s about protecting your entire building envelope. At VCE, we inspect and treat walls, windows, doors, siding, foundations, and transitions to ensure water can’t penetrate your home’s structure. Our team works closely with property owners to design a system that supports long-term durability and energy efficiency.

Hillside & Coastal Waterproofing Expertise

Homes built into hillsides or near the bay face unique hydrostatic pressure and runoff challenges. Our team specializes in waterproofing for:

  • Retaining walls and foundation walls
  • Sloped lots with poor drainage
  • Coastal exposure to wind-driven rain
  • Older homes with failing waterproof membranes

We customize solutions for each topographic condition, ensuring your home is protected year-round, especially during California’s heavy winter rains.

WATERPROOFING FAQS

Some exterior waterproofing job, like foundation drainage or wall membrane replacement, may require a permit. As a licensed contractor, VCE handles all required permitting and inspections on your behalf.

Depending on the materials and location, most professional waterproofing systems last 10 to 20 years or more. We use commercial-grade membranes and coatings rated for long-term durability.

Late spring to early fall is the ideal time for exterior waterproofing in Marin County, as conditions are dry enough for materials to cure properly. However, emergency repairs can be completed year-round.

Yes — VCE provides full-service waterproofing in Marin County for multi-unit buildings, schools, retail centers, and industrial structures, with custom solutions for flat roofs, parapets, and below-grade walls.

Absolutely. By sealing leaks and reducing moisture, waterproofing helps maintain stable indoor temperatures and prevents insulation breakdown, leading to better energy performance.

INTEGRATED STRUCTURAL REPAIR

In many cases, moisture damage goes hand-in-hand with dry rot, siding failure, or foundation movement. As a licensed general contractor, VCE can not only waterproof your property, but repair the underlying structural issues, saving you time, money, and hassle.

We specialize in identifying where water intrusion has already compromised framing, sheathing, or support systems—and we restore those components to code-compliant condition using durable, long-lasting materials. Whether it’s replacing rotted sill plates, reinforcing weakened studs, or correcting sloped subfloors, our team delivers comprehensive repair that prevents repeat failures.

According to the International Institute of Building Enclosure Consultants, up to 90% of all building damage in the U.S. is linked to moisture. VCE ensures your waterproofing solution isn’t just surface-deep — it’s structurally sound from the inside out.
