ACE traces water intrusion in Sacramento, California buildings back to its actual source, not just where it stains the ceiling. We combine moisture mapping, infrared thermography, and ASTM E2128 calibrated spray testing to reproduce the leak under controlled conditions. Signed cause-of-loss reports meet what insurance carriers require for coverage determination and subrogation — quoted fixed-fee before we start.
A leak that stains a lobby ceiling almost never enters the building at the stain. Water tracks along framing, along flashing pans, and inside cavity space until it hits the first discontinuous membrane. Forensic leak investigation is the systematic process of tracing that path back to the source — using moisture mapping, thermal imaging, calibrated spray testing, and where necessary destructive openings — so the repair addresses the cause instead of the symptom.

Sacramento sits in a Hot-Dry Valley (Zone 3B Warm-Dry) climate zone. Central Valley and inland-empire climates combine sustained summer heat with concentrated winter atmospheric-river rain events. Wall-assembly design has to handle both — high thermal load in summer and high moisture load in a narrow winter window when the drainage plane matters most. The Sacramento building stock we most often work in includes state-office corridors, midtown mixed-use, and Natomas suburban multifamily. In Sacramento the leak’s visible location and its actual source are often on different elevations — water enters at a wind-driven parapet and manifests three floors down at a corner window head. See our California statewide program for the multi-market context, and Envelope Consulting — Sacramento for a complementary scope in the same market.
Leak forensics rarely find water where damage appears. ACE traces the concealed path from suspected entry to observed staining, using sequential spray tests and moisture mapping.
Covering Sacramento leak detection and related scopes
Floor plans marked with observed stains, elevations, and moisture-meter readings — the starting point of every trace.
Non-invasive and pin-type moisture readings across suspect areas to define the wetted zone before opening anything.
Under evaporative or temperature-differential load, IR imaging shows the wetted framing and insulation the naked eye cannot see.
Isolated water application per ASTM E2128 — one joint, one component at a time — until the leak is reproduced under controlled conditions.
Written findings identifying the primary defect, contributing conditions, and recommended repair scope prioritized by risk.
Every engagement follows a three-phase delivery structure so you know what you are getting, when.
The three we see most often: wind-driven rain penetration at window-head transitions, deck-to-wall interface at balcony junctions, and parapet-cap failures where flashing continuity was broken.
Often yes — a combination of moisture mapping, IR imaging, and calibrated exterior spray-testing localizes the entry point on the exterior first. Openings are made surgically, only where the non-destructive work indicates, so the cost of repair is not compounded by the cost of investigation.
A single-source leak on a smaller building can resolve in a day of field work. Multi-source or facade-scale water intrusion typically requires several days of testing plus laboratory analysis of collected samples. The report follows within one to two weeks of field completion.
Leak investigation is priced by field-work days plus reporting. Single-source leaks on smaller buildings frequently resolve in one field day plus a week for reporting; facade-scale multi-source investigations run several field days plus laboratory analysis. Quoted fixed-fee before mobilization.
Yes. Cause-of-loss identification and repair design are two separate engagements. Many owners engage ACE first for the cause-of-loss report — the record insurance carriers and subrogation attorneys need — and then bid the repair to a contractor separately.
ACE Building Envelope Design has practiced envelope engineering across the Western United States on hundreds of commercial, multifamily, institutional, and legal-defense projects. Our senior engineers are licensed Professional Engineers, active in FGIA and ASTM committees, and have provided expert testimony in state and federal envelope-defect matters.
Founded and led by Conor Meyers (CEO), with John Harris (President) and Jedidiah Brandman (SVP) directing the technical practice.
