San Jose, CA Leak Detection & Consulting
Finding the True Source of Water Intrusion in San Jose Commercial Buildings
Building Envelope Leak Detection in San Jose, CA
With a short rainy season, San Jose leaks can go unnoticed for most of the year and then appear all at once in the first big storm. Water may slip through a dried-out joint between tilt-up panels, past a worn window seal on a downtown office, or under loose flashing around rooftop equipment, then run along the structure before it shows up somewhere else. Patching the stain does not stop it. Presto Restoration uses controlled testing and close inspection to find exactly where water gets in, with more than 25 years of experience on offices, R&D buildings, hospitals, campuses and historic properties. In San Jose, the goal is to fix the cause once.
OUR DIAGNOSTIC METHODS FOR SAN JOSE BUILDINGS
We choose the tests that answer the questions your San Jose building raises and skip the ones that would not change the repair.
Since it rarely rains for much of the year, we bring the rain ourselves. Controlled water testing wets one small area at a time while a technician watches inside, showing exactly which joint or seal fails.
Thermal cameras show temperature differences that point to wet insulation and air leaks behind walls and roofs.
Moisture readings show how far water has spread, and follow-up readings confirm repaired areas are drying.
Drones give us a close, safe look at upper walls, parapets and large roofs, revealing failed sealant and loose flashing.
If the evidence is still unclear, we open a small, controlled section to look at the flashing, insulation and framing directly, then close and seal it.
We size each investigation to the problem, from one leaking window to repeat leaks across a campus, and explain why every step is included.

San Jose Leak Detection & Consulting FAQs
Does Presto offer leak detection as a standalone service in San Jose?
No. Our leak investigations are part of larger commercial restoration projects, which typically start at $50,000. For an inspection report alone, a specialty engineering firm is the better fit.
What methods does Presto use to find leaks in San Jose buildings?
Controlled water testing, infrared thermography, moisture mapping, drone inspection and, when needed, small investigation openings.
Why does diagnostic work matter before restoration?
Repairing the wrong component wastes money and leaves the leak in place. Confirming the entry point first makes the repair last.
Does Presto provide expert witness or litigation support?
No. Presto does not provide forensic engineering, expert witness testimony or litigation support, and we recommend a specialty forensic engineering firm for that work.
What does a diagnostic report include?
Photographs of what we found, the confirmed entry points, test results and a repair plan in priority order.
How long does diagnostic work take?
About a day or two for one problem area, or a couple of weeks for a full study of a large building.
