Danny Deck Construction brings more than 20 years of experience to residential and commercial deck waterproofing in Sherman Oaks, protecting outdoor surfaces from leaks, moisture damage, and long-term structural issues. Whether you’re dealing with cracks, peeling coatings, soft spots, or water intrusion into rooms below, our team can diagnose the problem and restore your deck with a durable, watertight system built to last.

We waterproof all elevated outdoor surfaces — second-story decks, rooftop decks, balconies, and pool-adjacent structures — and we work extensively with HOAs, apartment buildings, and multi-unit homes, where waterproofing demands are frequent and must meet strict durability standards. Our process includes repairing or replacing damaged plywood, correcting slope and drainage issues, reinforcing compromised framing, and applying our professional 7-layer fiberglass waterproofing system. We specialize in Desert Crete, one of California’s most trusted waterproof assemblies, built to withstand heavy foot traffic, intense sun exposure, and years of outdoor use in Sherman Oaks.

Every project is completed with clean workmanship, durable materials, and code-compliant installation. Our waterproofing systems include a long-lasting warranty, giving you peace of mind and a deck that stays dry, safe, and structurally protected for years to come.
