Waterproofing Systems That Stop Water Intrusion at the Source
Exterior Systems Construction provides professional waterproofing services in Los Angeles for residential, commercial, HOA, and multi-unit properties. We handle interior waterproofing, exterior waterproofing, balcony systems, and rooftop courtyard protection with a diagnostic-first approach that helps stop water intrusion before it causes bigger damage.
Above-Grade Waterproofing for Walls, Balconies & Elevated Surfaces
Our above-grade waterproofing work focuses on the exposed exterior systems that protect occupied spaces: exterior walls, balconies, elevated walkways, rooftop courtyards, and the transitions where these assemblies meet. We assess the condition and source of moisture before recommending targeted waterproofing or repairs.
For recurring leaks around walls or openings, start with building envelope testing and moisture analysis. For damaged walking surfaces or failed coatings, explore our balcony waterproofing and repair services.
Learn the warning signs of above-grade envelope leaks and the difference between balcony waterproofing and maintenance recoating. Request an assessment with photos and a description of the affected exterior area.
