Exterior Systems Construction

At Exterior Systems Construction, we specialize in roofing, waterproofing, drainage, and exterior building repairs throughout Los Angeles. Our approach is simple: we diagnose the problem before we fix it. Water intrusion is often caused by more than one failed component. That’s why we look at the overall exterior system — including roofing, waterproofing, flashing, balconies, drainage, stucco, and other areas where water can enter. Our services include: • Roofing repairs and system upgrades • Waterproofing • Water intrusion testing • Balcony and stair repairs • Drainage and water diversion • Flashing and penetration repairs • Stucco repairs and exterior coatings • Building envelope repairs We work with homeowners, property managers, HOAs, and commercial properties on everything from localized repairs to larger exterior restoration projects. Whether you’re dealing with an active leak, recurring water intrusion, deteriorated waterproofing, drainage problems, or exterior deterioration, our goal is to identify the underlying issue and provide a reliable, long-term solution. We don’t just patch the symptom. We look for the source.
