Portland, OR Leak Detection & Consulting
Finding the True Source of Water Intrusion in Portland Commercial Buildings
Building Envelope Leak Detection in Portland, OR
Portland leaks tend to be slow and persistent rather than sudden. A small gap in a window seal or a cracked terra cotta joint can let in a little water every day from November through May, and by the time a stain appears, the water may have been traveling inside the wall for months. Moss on a parapet can hold water against a failing flashing, and wind-driven winter rain can reach joints on the west and south faces that rarely see water otherwise. Water might enter at an open joint behind terra cotta downtown, a worn window seal in a Pearl District loft or a clogged scupper on a medical office roof. Presto Restoration uses controlled testing and close inspection to prove exactly where water gets in, with more than 25 years of experience on towers, offices, hospitals, campuses and historic landmarks. In Portland, the goal is to fix the real cause once.
OUR DIAGNOSTIC METHODS FOR PORTLAND BUILDINGS
Each test we run on a Portland building has to tell us something that changes the repair. If it will not, we skip it.
With steady rain everywhere, it can be hard to tell which joint is the problem. Controlled water testing isolates one marked section at a time while a technician watches inside, until the failing spot shows itself.
Thermal imaging maps damp areas behind masonry and cladding, helping us trace water that has spread through a wall over many weeks.
Moisture readings show how far water has traveled and how long areas have been wet, and later readings confirm repairs are drying.
Drones let us inspect roofs, parapets and upper walls for moss, ponding and open joints without scaffolding.
When the evidence is unclear, we open a small area or remove a single unit to inspect anchors, flashing and sheathing directly, then close and seal it.
A single seeping window gets a short, focused test, while long-running leaks across a tower may need a full study. We explain why each step is included.
How Diagnostic Work Fits Into Your Portland Restoration Project
Every Portland project starts by proving how and where water gets in, so the repair plan rests on evidence.
Exterior Survey & Leak History
Building staff tell us where stains appear and how they change through the season, and we look for rust, efflorescence and growth outside.
Diagnostic Testing
Each suspected entry point is proven with a test before it goes into the plan.
Report & Scope
A written report explains what failed, including anchor corrosion and long-term moisture damage, and what to fix first.
Restoration Execution
Presto crews make the repairs, from sealants and flashing to terra cotta and coatings, during dry weather windows.
Verification & Closeout
Where possible, we retest the repaired area to prove it stays dry.

Portland Leak Detection & Consulting FAQs
Does Presto offer leak detection as a standalone service in Portland?
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 Portland buildings?
Controlled water testing comes first, with thermal imaging, moisture readings and drone inspection added as needed. Small openings are used only when nothing else will settle it.
Why do stains keep growing even though it never rains hard?
Portland’s steady drizzle feeds small openings every day for months. Water travels slowly through the wall, so stains spread over time rather than appearing all at once.
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 each problem, the entry points we confirmed, every test result and a repair list ranked by priority.
How long does diagnostic work take?
A day or two for one area, or a couple of weeks for a full study of a large tower or campus.
