Damp Proofing AmmanfordThe Ammanford figure
Checkatrade's own data puts the average cost of damp proofing in Ammanford at £1,400, with most jobs falling between £962 and £2,076. That's the most locally relevant figure we've found, and a reasonable starting point before you book a survey.
Typical costs by job type
Booking a survey doesn't commit you to anything. The ranges below are for the actual remedial work, and come from cross-checking several published UK price guides against each other, not from a single source.
| Job type | Typical cost |
|---|---|
| Injection damp-proof course | £40–£150 per linear metre, roughly £1,000–£3,000 for an average semi |
| Single-room rising damp treatment | £300–£2,500 |
| Full ground-floor DPC with replastering | £2,000–£5,000 |
| Condensation treatment (ventilation/extraction) | Around £200 per wall, up to £2,000–£5,000 for a whole house |
Remedial-work ranges pulled from published price guides and quotes from Checkatrade, MyBuilder, MyJobQuote, the Federation of Master Builders, the Federation of Damp, Kingfisher UK, Sussex Damp Experts, Dower Damp Proofing and Syla Damp Proofing. Every home is different, so treat these as a starting point, not a quote.
Why the price varies so much
Cost depends on how much wall is affected, whether the plaster needs stripping and replacing, how easy the area is to access, and whether it's a straightforward injection job or something bigger, like a full ground-floor damp-proof course. Two houses with "rising damp" written on the survey report can end up needing very different amounts of work. Our rising damp guide goes into more detail on what drives that specific job's cost.
Selling a house with damp?
Damp doesn't stop you selling, but it usually has to be disclosed on the TA6 property information form if you know about it, and it's one of the things a mortgage valuation or homebuyer's survey commonly picks up. The English Housing Survey found damp problems in 6% of homes overall, 4% of owner-occupied homes and up to 9 to 11% of privately rented ones, so it's a common finding, not a red flag on its own. Sorting it before you list tends to cost less than a buyer renegotiating after their own survey turns it up.
Common questions
How much should damp proofing cost?
There's no single number since it depends on the job, but as a general guide, Checkatrade's own data puts the Ammanford average at £1,400, with most jobs between £962 and £2,076. See the table above for a breakdown by job type.
Is it illegal to sell a property with damp?
No. Damp on its own isn't a legal barrier to selling, but you do need to disclose it on the TA6 property information form if you're aware of it. Most sellers either fix it before listing or price it into the sale.
Are there government grants for damp proofing?
There's no dedicated, UK-wide grant specifically for damp proofing. Some broader home-improvement or energy-efficiency schemes occasionally cover related work, like insulation or ventilation, but eligibility changes often. Your local council or gov.uk's own grant checker is the most reliable place to see what you might currently qualify for.
Can rising damp be permanently fixed?
Yes, if the cause is dealt with properly. A correctly installed damp-proof course, combined with replastering where needed, should stop rising damp for good. Problems that come back are usually down to something being missed at the diagnosis stage, like penetrating damp being mistaken for rising damp, rather than the treatment itself failing.
