Inspection and testing in Central Bucks County, PA
Before anybody quotes you for anything. A few hundred dollars here decides whether the next conversation is about $3,000 or $90,000.
A stucco inspection uses invasive moisture probes to measure the moisture content of the sheathing behind the cladding, at the points where water is most likely to collect. It costs roughly $450 to $1,600 in this region and is the only reliable way to establish whether a wall needs remediation, needs repair, or needs nothing at all.
Why it has to be invasive
A surface scan with a non-invasive meter reads the outer face of the cladding. The problem is not on the outer face of the cladding — it is in the sheathing behind it, under an inch of cement or foam. A non-invasive scan on a stucco wall can miss serious sheathing rot entirely, which is why a general home inspection is not a substitute for this.
An invasive inspection drills small holes through the cladding and inserts a probe that reads the moisture content of the wood itself. That is the measurement that means something, and the holes are patched before the inspector leaves.
What the readings mean
- Under about 15% — normal for wood in a wall assembly.
- Roughly 16–19% — elevated. Worth understanding why, and worth re-testing.
- 20% and above — the level at which decay becomes a live concern. The wall is wet, not damp.
Context matters as much as the number. One elevated reading below a single window says something quite different from consistently elevated readings across three elevations.
Who should get one
Anyone buying a stucco home built between roughly 1992 and 2007, before the contingency period ends. Owners of homes from that window, whether or not anything is visible — a great many walls test wet with nothing showing outside. Anyone holding a repair or coating quote, before accepting it. And anyone whose neighbours have found problems, because whole streets were built by the same builder to the same detail in the same two years.
The conflict of interest to watch for
Some inspections are carried out by companies that also sell remediation. That is not automatically wrong — the crews who repair these walls often understand them best — but it is worth knowing when you read the recommendation. Ask for the raw readings and photographs as a standalone document so you can put the same evidence in front of somebody else. Full guide to what happens on the day.
