What to check when hiring damp proofing / waterproofing in the United Kingdom
MyTrustedTraders ranks on independent public evidence. No ads, no paid placement. Use these checks alongside the evidence on each profile before you decide who to contact.
- Get an INDEPENDENT damp survey, not a free one from the firm that wants to sell you the treatment. A free survey has every incentive to diagnose expensive 'rising damp', when the problem is often condensation, a leak, or high ground level that needs no chemical injection.
- Insist they identify and fix the underlying CAUSE (a leak, blocked airbricks, poor ventilation, failed pointing) before agreeing to an injected damp-proof course, and ask them to explain why simpler fixes won't work.
- Get the diagnosis and an itemised quote in writing, and be wary of pressure to sign on the spot for a long 'guarantee' that is only worth anything while that firm is still trading.
- Look for a surveyor or contractor accredited by the Property Care Association (PCA), the recognised UK body for damp and timber, and prefer an independent surveyor holding CSRT (now CSTDB) or CSSW for the diagnosis itself.
- Look for consistent reviews across several named sources, not one polished profile.

How to judge a damp proofing / waterproofing
Independent, no-ads guidance. The trade-specific checks that matter most, the warning signs, and what to ask before you hire. Use it alongside each trader’s public evidence above.
Verify before you hire
- Check the contractor is a member of the Property Care Association (PCA): the main vetted trade body for damp specialists in the UK.
- Ask whether the surveyor holds a CSRT (now CSTDB) or CSSW qualification: these are the recognised professional credentials, not a short sales course.
- Confirm any guarantee is backed by an Insurance Backed Guarantee (IBG) from a named insurer, so it remains valid if the company folds.
- If your home was built before 1919 or is in a conservation area, check the contractor has experience with heritage-compatible methods.
Warning signs of a cowboy
- The company surveying the damp is the same company selling you the treatment: a direct financial incentive to over-diagnose.
- No written diagnosis report explaining the actual cause, just a quote for chemical injection or replastering.
- A long guarantee (20–30 years) offered without any mention of an underwritten insurance policy behind it.
- A recently registered company offering decades-long guarantees: check their Companies House incorporation date.
Questions to ask before you hire
- Are you PCA-accredited, and does the surveyor hold a CSRT (now CSTDB) or CSSW qualification?
- Will you give me a written report naming the cause of the damp before any work starts?
- Is the guarantee backed by an insurance policy from a named, FCA-authorised insurer?
- Could this be condensation rather than rising damp: and how will you rule that out?
Frequently asked questions
- How do I choose a trustworthy damp proofing / waterproofing?
- Compare the public evidence on each profile: how many independent reviews they have and across how many named sources, the rating and how recent it is, any credential evidence, and the company status. A damp proofing / waterproofing backed by several named sources is harder to fake than one found in only one place.
- Does MyTrustedTraders rank or recommend damp proofing / waterproofing for payment?
- No. There are no ads and no paid placement. Damp proofing / waterproofing are ranked only by the strength of independent public evidence. No one can pay to rank higher, add a badge, or change their reviews.
- Where do the reviews come from?
- They're imported from named public review sources and always shown with the source named. They aren't reviews written on MyTrustedTraders. We cross-check the same business across sources rather than creating new reviews.
- What should I check before hiring a damp proofing / waterproofing?
- Confirm credentials and insurance directly with the damp proofing / waterproofing, get a written quote, and run the Cowboy Checker on the business first. MyTrustedTraders helps you shortlist on the evidence. It doesn't replace your own checks before you hire.
