Damp Subsidence and Specialist Referral Questions

Further investigation recommended is not a diagnosis. A checklist for commissioning the specialist properly.


A report recommends further investigation of a damp issue and a specialist opinion on movement at the rear of a property.

The buyer calls two companies offering free damp surveys. Both attend, both find extensive problems, and both quote several thousand pounds for treatment they would carry out themselves.

She has not obtained a diagnosis. She has obtained two sales visits, and the independent opinion that would have cost a few hundred pounds was never sought.

1. Understand what the recommendation actually says

Something could not be assessed visually. It is not a finding, it is an acknowledgement of the limits of the inspection, and it should be read that way.

2. Do not commission the work before the diagnosis

The single most expensive mistake in this area. Treatment recommended by whoever would carry it out is a quotation rather than an assessment.

3. Pay for an independent opinion

An independent specialist with no interest in the remedial work will tell you what is actually happening. This costs a fraction of any treatment and frequently concludes that far less is needed.

4. Understand what a free inspection is

A sales visit by a contractor. They may be entirely competent and their commercial interest in finding a problem is unavoidable and should be factored in.

5. Know which specialist to commission for what

Movement questions go to a structural engineer, damp questions to an independent damp specialist, timber to a specialist surveyor, drainage to a drainage contractor with a camera.

6. Understand that damp has several causes

Condensation, penetrating damp, leaks, bridged construction and rising damp are different problems with different remedies, and the commonest is frequently the cheapest to fix.

7. Treat movement findings calmly

Many properties show historic movement that is long since stable. The question is whether it is progressive, which requires monitoring rather than panic, and the alarm is covered in damp and condensation findings buyers panic about.

8. Ask how long monitoring would take

Where movement needs monitoring, it takes months rather than days. Buyers in a chain need to know this before committing to the route.

9. Ask what the insurer's position is

Where a property has a history of movement, the insurance position matters as much as the structural one and it is rarely considered at this stage.

10. Get the specialist report in writing

With findings, cause, recommendation and urgency. A verbal opinion from a site visit is not something you can act on or negotiate with.

11. Use the report to obtain costs properly

Three quotations against a defined specification, rather than three companies each proposing their own scope. This is the only way to compare anything.

12. Keep the timescale realistic in a chain

Specialist reports take time and buyers are under pressure from other people's deadlines, which is the ground in report turnaround and chain pressure questions.

13. Keep the referral routes clear

Knowing exactly who to send somebody to, and why, is what makes a referral useful rather than a deflection, which is the same discipline as referral and requisition questions from clinicians.

14. Explain the referral at the hour the report is read

An assistant that explains what further investigation means, which specialist handles which question, why a free inspection is a sales visit and what an independent report costs reaches a buyer before she telephones two contractors. Handled with the care in how to handle sensitive questions in your chatbot. See features, start at try, and the sector view sits under architects.

Frequently asked questions

What does a recommendation for further investigation mean?
That the surveyor could not fully assess something from a visual inspection and is recommending somebody with the right equipment or expertise look at it properly.
Who should carry out a specialist investigation?
Ideally an independent specialist paid for their opinion rather than a contractor offering a free inspection, because the second has an obvious interest in finding work.
How much do specialist reports cost?
Considerably less than the work they might recommend, which is why paying for an independent opinion before commissioning any remedial work is almost always worthwhile.
