What makes waterproofing services different in Northridge

Northridge sits in the north-central Valley around CSUN. The housing stock is heavily 1950s–1970s ranch and post-war traditional on wider-than-Valley-average lots. Most homes carry original 100A or 125A panels (now undersized for induction cooktops, EV chargers, and modern HVAC), and original galvanized supply lines that benefit from a repipe during any meaningful remodel.

Most Northridge homes were built before 1980. That means galvanized supply lines, undersized electrical panels, original gas runs, and rough-in plumbing that hasn't been touched in decades. Once walls open during a waterproofing services project, we expect to bring the underlying systems to current code — not as a surprise, as a plan.

Common architecture in Northridge: Ranch, Mid-Century Modern, Spanish Colonial Revival. We design san fernando valley renovations to honor what's already there while bringing systems and finishes up to current code and current standards.

Waterproofing Services in Northridge — Frequently Asked Questions

Signs include musty smells, visible mold, water stains on ceilings or walls, efflorescence on foundation walls (white mineral deposits), standing water after rain, and peeling paint in below-grade areas. If you notice any of these, we recommend an assessment.

Exterior foundation waterproofing involves excavating along the foundation wall, applying a waterproof membrane, installing drainage board, and placing a French drain at the footing to direct water away from the structure. For interior solutions, we install drainage channels and sump pumps.

Traffic-rated deck coatings typically last 8–15 years depending on foot traffic, UV exposure, and maintenance. We recommend an inspection every 3–5 years and recoating when the surface shows signs of wear or cracking.

Yes — always. Shower waterproofing is a non-negotiable standard on every bathroom remodel we do. We use Schluter Kerdi membrane systems and flood-test every shower before tiling begins.
