We serve Mountain View, CA, bringing over 30 years of Bay Area waterproofing expertise to homeowners across Santa Clara County.

Call (650) 341-6932 to request a free estimate and stop water problems before they become structural ones.
Why Mountain View Homes Are Vulnerable to Basement Water Intrusion
Mountain View sits on clay-rich adobe soils that swell when saturated and shrink during dry summers. That repeated expansion and contraction stresses foundation walls, and hairline cracks form over time. Neighborhoods like Cuesta Park and Monta Loma, where many homes were built before 1980, often feature older foundation designs never engineered for modern waterproofing standards. Areas near Stevens Creek can experience a higher water table during the rainy season, increasing hydrostatic pressure against below-grade walls. Bay Area winters bring concentrated seasonal rainfall that compounds the problem in homes without proper drainage.
We were founded in 1993 by civil engineer Jacob Habache. Decades of working in Bay Area soil conditions directly inform how we approach every project in Mountain View, CA.
Residential Basement Waterproofing Methods We Use
The right approach depends on your home's construction, soil conditions, and moisture source.
Interior Drainage Systems
An interior perimeter drain captures water seeping through the foundation and channels it toward a sump pump before it spreads across the floor. This is often the most practical solution for finished or semi-finished basements in Old Mountain View and Waverly Park.
Sump Pump Installation and Service
A properly sized sump pump discharges collected water away from the structure. Battery backup systems keep the pump running during power outages, which matter during Santa Clara County storm events. We can assess whether your current system is adequate or needs an upgrade.
Crack Injection and Sealing
Epoxy and polyurethane crack injection repairs structural cracks in poured concrete walls and stops active seepage. This targeted method works well for homes in North Whisman and Shoreline West with isolated wall cracks rather than widespread drainage failure.
Crawl Space Encapsulation
Many Mountain View homes have crawl spaces rather than full basements. A sealed vapor barrier system reduces ground moisture migration, prevents mold growth, and improves air quality. This is a common need in Rex Manor and Gemello, where older homes often have vented crawl spaces exposed to seasonal moisture.
Exterior Waterproofing and Membrane Coating
Exterior waterproofing applies a membrane to the outside of foundation walls and improves site drainage. We also offer exterior waterproofing services for projects where exterior access is practical.

Frequently Asked Questions
What Causes a Wet Basement in Mountain View, CA?
The most common causes are hydrostatic pressure from clay soils, foundation wall cracks, and inadequate site drainage. Mountain View's adobe clay holds moisture rather than draining it, pushing water against foundation walls over time.
How Do I Know If I Need a Basement Waterproofing Company?
Signs include visible water stains, efflorescence on walls, musty odors, standing water after rain, or foundation cracks. Any of these symptoms warrant a professional inspection before damage worsens.
Is Crawl Space Encapsulation Different From Basement Waterproofing?
Yes, though both address moisture control. Crawl space encapsulation uses a sealed vapor barrier to block ground moisture, while basement waterproofing typically involves drainage systems, sump pumps, and crack repair. Many Mountain View homes need one or both depending on construction type.
Can I Waterproof My Basement Myself?
DIY products may offer temporary relief for minor surface moisture but rarely address the root cause. Improper installation can trap moisture inside walls and accelerate damage. A licensed contractor with knowledge of local soil and foundation conditions delivers a lasting solution. For reliable results, residential basement waterproofing performed by an experienced professional is the recommended path forward.
