Signs to watch
Is this you?
A stain or leak, and no one can find the source
Water travels along framing and sheathing before it shows up inside, so the stain is rarely under the entry point. Finding where it actually gets in — not just where it drips — is the entire job, and it's a specific skill.
A previous 'fix' didn't stop it
When a repair doesn't hold, it usually means the real pathway was never found — the caulk went on the symptom, not the source. Chasing it methodically beats sealing everything in sight and hoping.
Musty smell, soft spots, or peeling paint
Musty odors, spongy trim or subfloor, and bubbling paint are the outward signs of moisture already in the assembly. They tell us water is getting in; they don't yet tell us where, which is what the investigation is for.
Recurring problems at windows or wall transitions
The Northwest's hardest leaks live at transitions — window heads and sills, roof-to-wall junctions, deck ledgers, and any spot two materials meet. That's where flashing and sequencing fail, and where we look first.
Your options
A methodical hunt for the pathway, with honest limits
We investigate the building envelope the way water actually moves through it: starting from the symptom inside and working outward along the likely pathways. We examine the exterior entry points — flashing at chimneys, skylights, windows, and roof-to-wall transitions, siding laps and penetrations, deck ledgers, and drainage that dumps against the wall — and, where it's warranted, use moisture meters and targeted probing to map how far the moisture has traveled. What we won't do is conclusively diagnose a hidden structural or moisture problem from the outside and hand you a scary certainty. Some pathways can only be confirmed by opening a wall, running a controlled water test, or bringing in an infrared or forensic specialist — and when the evidence points past what a visual and moisture-meter look can confirm, we tell you that plainly and help you escalate rather than guessing on your dime. The goal is to find the real source so you fix that, once, instead of the wrong thing twice.
The method
How we do it
- 01
Map the symptom and the likely paths
We document where the water shows up inside and trace back along the framing and assembly to the exterior points most likely to be letting it in. Photos and notes at every step.
- 02
Investigate the exterior pathways
Flashing, windows, roof-to-wall transitions, penetrations, and drainage examined in the order water is most likely using — with moisture readings and, where needed, a controlled water test to confirm the source.
- 03
Findings, limits, and next step
You get what we found, how confident we are, and what it would take to confirm anything still uncertain — a wall opening, a specialist, or a repair scope — laid out honestly, not oversold.
Straight numbers
How diagnosis pricing works
A straightforward leak we can trace on a visual and moisture-meter visit is often covered in a standard inspection, especially when it leads to a repair we quote. A deeper forensic investigation — controlled water testing, invasive openings, or coordinating a specialist — is a paid diagnostic scope, and we'll tell you which one your situation calls for before any billing starts. What we won't do is guess to avoid the harder answer: if finding the real source takes more than a look, we'll price that plainly so you're paying to actually solve it, not to hear a comforting maybe.
Where we do this work
Building Envelope & Water Intrusion Diagnosis: straight answers
Can you tell me exactly what's wrong from one visit?
Sometimes — a clear pathway at a flashing or window shows itself on a good visual and moisture-meter inspection. But water is deceptive, and some sources only reveal themselves under a controlled water test or behind an opened wall. We'll tell you how confident we are and what it would take to be sure, rather than handing you false certainty.
Why do I need diagnosis instead of just sealing everything?
Because sealing everything usually seals the wrong thing. Caulk over a symptom while the real pathway keeps feeding water behind it, and you've hidden the problem, not fixed it. Finding the actual source first is what makes one repair hold instead of three that don't.
What if the problem is inside the wall or structural?
Then we say so and help you get the right eyes on it. If the evidence points to rot or moisture inside the assembly, confirming and scoping it can call for opening the wall, an infrared scan, or a forensic or structural specialist. We'll be straight about where our diagnosis ends and hand you off cleanly rather than pretending to see through the siding.
Do you fix what you find, or just diagnose it?
Both, when the fix is in our lane — flashing, roof-to-wall, siding, trim, and drainage are exactly what we repair. If the source turns out to be plumbing, an interior condensation problem, or something structural, we'll tell you honestly that it belongs to another trade and point you to the right one.
