San Diego, CA Leak Detection & Consulting
Finding the True Source of Water Intrusion in San Diego Commercial Buildings
Building Envelope Leak Detection in San Diego, CA
Because it rains so rarely in San Diego, a leak can stay hidden for months and then soak a ceiling during the first strong winter storm. Wind off the ocean can push water past a balcony door seal on a bayfront condo, under a corroded flashing on a hotel roof, or through a crack in a downtown tower’s concrete before it shows up somewhere unexpected. Salt carried in with that water adds corrosion to the damage. Presto Restoration uses controlled testing and close inspection to find exactly where water enters, with more than 25 years of experience on towers, hotels, hospitals, research buildings and historic properties. In San Diego, the goal is to fix the cause once so the leak does not keep coming back.
OUR DIAGNOSTIC METHODS FOR SAN DIEGO BUILDINGS
We pick the tests that answer the questions your San Diego building is raising, and we skip the ones that would not change the repair.
With so few rainy days, waiting for a storm is not a plan. Controlled water testing recreates the leak on demand, wetting one small area at a time while a technician watches inside to pinpoint the failure.
Thermal cameras pick up small temperature shifts across a wall or roof, pointing us to damp insulation and air leaks we cannot see.
A moisture meter tells us how wet each area is and how far the water has spread, and follow-up readings show when repairs have dried out.
Drones give us a close look at upper walls, balconies, parapets and roofs without scaffolding, revealing failed sealant, cracks and corroded flashing.
If the evidence is still unclear, we cut a small, controlled opening to see the flashing, waterproofing and framing firsthand, then patch and seal it.
A single leaking balcony door may need one short test, while repeat leaks across a hotel tower may call for a full study. Either way, we explain why each step is worth doing.

San Diego Leak Detection & Consulting FAQs
Does Presto offer leak detection as a standalone service in San Diego?
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 Diego buildings?
We use controlled water tests, thermal imaging, moisture readings and drone photos, and we open small inspection areas when we need a direct look.
Why does diagnostic work matter before restoration?
Fixing the wrong part of the building wastes money and leaves the leak in place. Confirming the entry point first makes the restoration 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?
Photos of what we found, each confirmed entry point, test results and a repair plan listed in order of priority.
How long does diagnostic work take?
One problem area usually takes a day or two. A full study of a large building can take a couple of weeks.
