Damp and moisture meters
The report says further investigation by a damp contractor. Why is that sentence not already a diagnosis of rising damp?
That sentence is not a diagnosis of rising damp because it only asks for further investigation. The survey has not named the mechanism. Rising damp, moisture drawn from the ground, is one possibility a contractor might consider, alongside leaks, bridged damp-proofing, rain penetration or condensation. The report has not chosen among them. It has recorded that the cause is still to be investigated. A recommendation to appoint someone is not the finding they have yet to make.

What is the fuller explanation?
Damp shows as staining, salt, a musty smell or a high reading, and those signs have more than one explanation. A home survey can say the signs are there and that a specialist should take them further. It cannot, by that sentence, convert the signs into rising damp. If a meter was used, a reading is still not a named mechanism, and this page does not pretend a test was a diagnosis. The contractor's visit is the investigation the sentence is pointing at. It has not happened inside the report.
Instruct a damp investigator who will say what the moisture is and what it is not, and keep their conclusion separate from this sentence. Tell the solicitor the survey has not diagnosed rising damp. Do not send the line to a builder as if it already specified injection or a new damp-proof course. The home survey stopped at further investigation. The cause remains open until that work is done.
What should you ask your surveyor?
- What signs did you record, short of naming rising damp?
- Is the damp-contractor sentence an instruction to investigate, not a diagnosis?
- Which causes did you leave open rather than settle on rising damp?
What are the typical next steps?
- Read the sentence as further investigation, not a rising-damp diagnosis.
- Ask an investigator to name the mechanism before any treatment is specified.
- Do not brief a builder as if injection had already been recommended.
Costs vary with the building and with who you instruct. Where this page does not cite a published figure, ask the surveyor, a relevant specialist, or your solicitor for a written quote. Do not treat a forum average as the price.
Also asked about this
If the skirting looks tide-marked, is rising damp now proved?
No. A tide mark is a pattern people associate with moisture. The report did not call it rising damp. It asked for a damp contractor to investigate. The survey has not shown that water is coming from the ground, and it has not ruled the other paths out. The mark stays a sign, not a diagnosis.
Does recommending a contractor mean the walls have failed?
It means the survey will not leave the cause on the visual evidence alone. Failure of a wall, a failed damp course, or a leak are different sentences, and none of them is what this line says. Further investigation is the finding. Until that visit happens, you do not have a diagnosis, and you do not have a specified repair.
