Complete Water Intrusion Testing Services for Inland Empire Properties
Water can travel through multiple building components before becoming visible inside your property. Our testing process helps identify hidden moisture issues and the true source of leaks.
Roof Leak Detection
Locate active and hidden roof leaks before they lead to more extensive structural damage.
Wall Moisture Testing
Detect moisture behind stucco, drywall, siding, and exterior wall systems that may not yet be visible.
Balcony Leak Testing
Inspect balconies, decks, elevated walkways, and waterproofing systems for hidden water entry points.
Building Envelope Testing
Evaluate how water is entering the exterior building envelope through walls, windows, roofs, joints, penetrations, and other vulnerable areas.
Moisture Intrusion Diagnosis
Identify the source of water intrusion before recommending repairs, helping property owners make informed decisions.
Water Damage Assessment
Evaluate affected areas, determine the extent of moisture damage, and recommend the next appropriate steps.
We Diagnose Before We Repair
Many water intrusion problems are misdiagnosed because the visible leak is often not where the water is entering.
FH Construction uses a systematic testing process to trace moisture back to its true source. Instead of replacing materials that may not be causing the issue, we focus on identifying how water is moving through the building.
This approach helps reduce unnecessary repairs, improves repair planning, and gives property owners greater confidence before work begins.
