Forensic Engineering in Pierce & King County

Call (253) 319-3220

Forensic Engineering · PE · Licensed in WA

Moisture meter on an opened tile floor during a condition check.

The two calls we get most

Code & red tag notices: the city or county posted a notice and wants an engineer. Disputes & litigation: two sides disagree about a building. We look at the facts and put it in writing.

Who calls us

Homeowners, landlords and property managers, attorneys, contractors, and real estate agents when a problem turns up during a sale.

How it works

You call and tell us what happened. We check for conflicts, visit the site with measurements and photos, tell you what we found (often by phone first), then write it up as a short letter or full report.

How we bill

Defined work gets a fixed price. Code, red tag and forensic work runs under a short hourly agreement. We estimate likely hours up front and tell you before it goes over.

Straight answers

We are paid for our time, not for a conclusion. If what we find does not help your side, we will tell you early. We do not give legal advice; for that you need an attorney.

Don't fix it yet

If you can, call before the repair. Once the damage is gone nobody can look at it again. If something is unsafe and cannot wait, take lots of photos and keep the removed pieces.

Got a notice or a problem? Just call.

Call, book, or email office@dowengineeringpllc.com. Attorneys can call the same number.

Water and drainage damage

Problems found during a sale

Cracks, sag, and movement

Retaining walls, soil, and runoff can hurt a structure over time. We look at cause and what a fair fix looks like.

Work done without a permit

Problems found during a sale
