What do damp surveys and damp proofing cost?
Damp proofing in Stafford costs whatever the cause demands, so this guide sets out credited national yardsticks for surveys, treatments, ventilation, timber and tanking. It is for homeowners, buyers and landlords weighing quotes, and it explains why paying for a sound diagnosis usually saves more than haggling over the survey fee.

What do national price guides say damp work costs?
A few hundred pounds for a survey, and from a few hundred to several thousand for most treatments. These are national averages from trade platforms and magazines, not our prices, and each carries its publisher and date; some pages show none.
| Job | National yardstick | Source and date |
|---|---|---|
| Damp survey | £100 to £600, average £300 | Checkatrade damp proofing guide, updated 6 April 2025, prices November 2024 |
| Damp survey, by house type | £150 to £500 overall: terrace £180 to £250, semi £200 to £300, detached £250 to £350 | MyBuilder, undated |
| Rising damp injection, whole job | £1,000 to £3,000, average £2,000 for a medium-sized property | Checkatrade damp proofing guide, as above |
| Injection, per metre | £60 to £200, average £100; or about £195 a metre including replastering | Checkatrade, as above; Homebuilding & Renovating, 9 April 2024 |
| Physical damp-proof course cut into an existing wall | £2,500 to £7,500, average £5,000 | Checkatrade, as above |
| Damp proofing external walls by injection | £1,000 to £3,000, average £2,000 | Checkatrade, as above |
| Extractor fan | New fan £250 to £350 (about £300); replacement £175 to £225 (about £200) | Checkatrade, last updated June 2026 |
| Positive input ventilation (PIV) | £763 to £1,750, average £900; or £700 to £1,000 installed | Checkatrade, prices May 2024; Homebuilding & Renovating, updated 12 July 2024 |
| Woodworm | Survey £80 to £250; loft of a three-bed house £400 to £900; treatment generally £500 to £1,000 | Checkatrade, updated 9 September 2024 |
| Dry rot | Survey £200 to £500; small local job £500 to £1,500; structural repair £1,500 to £5,000 a room; widespread rot £5,000 to £12,000 or more | MyBuilder, undated |
| Cellar tanking, per m² | £100 to £200, average £125; cementitious tanking £60 to £120; tanking slurry £30 to £60 | Checkatrade damp proofing guide, as above; MyBuilder cellar guide, undated, 2026 figures; Homebuilding & Renovating, 9 April 2024 |
| Cavity drain membrane, per m² | £80 to £150 | MyBuilder cellar guide, as above |
| Sump pump | £500 to £1,500 | MyBuilder cellar guide, as above |
Checkatrade heads its tables "Cost + VAT", which leaves it unclear whether VAT is included, so ask any firm whether its quote includes it. Where publishers disagree, both figures appear above.
Why do Checkatrade's two damp course pages disagree?
Neither page explains the gap, so the dated one is the better guide. Checkatrade's damp proofing cost breakdown, updated in April 2025 with prices from November 2024, puts a rising damp injection job at £1,000 to £3,000, with an average of £2,000 for a medium-sized property.
Its separate damp-proof course page, which carries no date, gives averages of £320 for a terrace, £700 for a semi and £1,750 for a detached house, "around £800" for a medium-sized property, and labour at £150 to £300 a day. Without a date there is no way to tell how old those figures are.
Per-metre prices need the same care. Homebuilding & Renovating estimates about £195 a metre including replastering, near the top of Checkatrade's range, so check whether a per-metre quote covers the plaster.
Does the price of the damp survey matter much?
Much less than what the survey concludes. On the national guides the fee is a few hundred pounds at most, while the work it recommends can run to thousands, so a wrong diagnosis costs far more than a dearer survey.
Which? says rising damp can be the most expensive kind of damp to fix yet is one of the least common, and that its investigation revealed bad practice among a number of specialist damp companies. It also notes that some firms charge for a damp report and refund the fee if you then use them for the work. That can be a fair arrangement, but it links the diagnosis to the sale. The 2022 joint position statement from RICS, Historic England and the Property Care Association says conflicts of interest should be stated in the report.
Which? advises getting quotes from at least three companies, and independent advice if their recommendations differ. RICS adds a simple test: be wary of anyone who diagnoses with a damp meter alone, because meters can give false high readings in masonry. Our damp surveys start with the cause, and the guide on telling rising damp from condensation shows why that changes the bill.
What makes a damp job in Stafford cost more or less?
Mostly the type of wall, whether the building is listed, and how much plaster has to come off and dry out.
Solid walls. The joint position statement describes traditional solid walls of brick, stone and lime as taking up moisture and releasing it in drier weather. On walls like these, SPAB says lime repointing or removing hard cement render may be the best answer, and waterproof coatings can make damp worse.
Listed buildings. The Planning Portal says "Typically, installing damp proofing will require listed building consent". Stafford borough has 836 listed buildings, 744 of them Grade II. Section 7 of the Planning (Listed Buildings and Conservation Areas) Act 1990 requires consent for works that would affect a listed building's character, so allow for the application and for a method the council will accept.
Plaster and drying time. The Property Care Association Code of Practice says salt-contaminated plaster should be removed to at least 300 mm above the last detectable dampness and replaced, and that impervious coatings should wait until walls have dried, which may take 1 to 12 months or longer. A quote that allows for both looks dearer, but it is the honest comparison.
Can a cheaper repair replace an expensive treatment?
Often, because the commonest causes are not the dearest to fix. UKHSA and DHSC guidance calls condensation the most common form of damp, and the English Housing Survey's surveyor-assessed figures for 2024 found serious condensation and mould in 3% of homes in England, penetrating damp in 2% and rising damp in 1%.
On the national guides above, a new extractor fan costs a few hundred pounds, against £1,000 to £3,000 for an injection job. Rain getting into a wall often comes down to gutters, downpipes or pointing: Homebuilding & Renovating, citing Checkatrade, gives repointing labour at £55 per m² for brickwork, and puts scaffolding, where it is needed, at £500 to £2,500. Our pages on condensation and mould and penetrating damp cover those repairs.
None of this means rising damp never needs treating. It means the evidence should come before the spending, and a quote for rising damp treatment should explain how the cheaper causes were ruled out.
What should a damp quote include?
The cause and the evidence for it, the full scope of work, and who made the diagnosis.
- The cause, and how it was confirmed: where readings or samples were taken, not a meter reading on its own.
- What is included: hacking off, replastering, making good, ventilation, and whether VAT is in the price.
- Whether listed building consent is needed, and who will apply for it.
- The surveyor's qualification. Ask whether they hold the Property Care Association's CSTDB (formerly CSRT) or CSDB, or the CSSW for cellars and basements.
- What any guarantee covers, and who stands behind it if the firm stops trading.
For damp proofing in Stafford, Stone, Cannock and the villages between, Stafford Damp Proofing prices work once the cause is known. If woodworm or rot is involved, the timber treatment page and our dry rot or wet rot guide explain what has to happen first.
Questions we get asked
Are these the prices Stafford Damp Proofing charges?
No. They are national averages from trade platforms and magazines, credited with their dates. A real price depends on what the survey finds in your house.
Is a cheap damp survey a false economy?
It can be if the diagnosis rests on a damp meter alone, because a wrong answer can lead to the most expensive treatment for the wrong problem. Ask how the cause will be confirmed, not just what the visit costs.
Do I need listed building consent for damp proofing?
The Planning Portal says installing damp proofing on a listed building typically needs it. Check with Stafford Borough Council before any work starts.
How many quotes should I get?
Which? advises at least three, and independent advice if the firms recommend different work.

Where this guide leads
Damp surveys
A survey that works out where the water is coming from, outside and in, before anyone mentions treatment.
Rising damp treatment
Ground moisture proved with samples first, then bridged damp courses cleared or a certified injection fitted where the evidence calls for it.
Woodworm and rot treatment
Woodworm, wet rot and dry rot identified properly, live or long dead, with the damp behind them fixed before any timber is treated.
