At Exterior Systems Construction, we provide custom drainage solutions throughout Los Angeles for residential, commercial, HOA, and multi-unit properties. From standing water and poor runoff to drainage failures that affect roofs, balconies, walkways, and foundations, we focus on diagnosing how water is moving across the property before recommending the right solution. Our goal is to help prevent water intrusion, erosion, and long-term structural damage.

Drainage problems are not always caused by the spot where water is visible. Pooling water, runoff damage, overflow, and moisture intrusion may all start with poor slope, blocked pathways, failed drains, or improper water flow across the property. That is why we begin with a diagnostic-first approach to identify the source of the drainage issue before recommending a fix.

By understanding how water is moving through and around the property, we help owners make better decisions, avoid unnecessary work, and protect their structures over the long term.

Drainage issues can quickly lead to larger problems for HOA boards and property managers when standing water, surface deterioration, roof runoff, and water intrusion begin affecting shared spaces and building systems. We work with HOAs and multi-unit property teams across Los Angeles to provide drainage corrections, roof drainage improvements, targeted testing, and long-term repair planning.

Whether the issue is visible pooling or hidden water movement affecting the structure, our team focuses on accurate diagnostics and practical solutions.
