The damp proofing industry has a problem. Alongside the many reputable, qualified professionals doing excellent work, there are companies that exploit homeowners’ concerns about damp to sell unnecessary, overpriced, or completely ineffective treatments.
Every year, thousands of UK homeowners pay for damp work that either wasn’t needed or doesn’t solve the problem. Knowing the warning signs can protect both your home and your wallet.
Common Scam Tactics
Pressure Selling and Scare Tactics
One of the clearest red flags is a sense of urgency that doesn’t match the situation. Dishonest companies will tell you that your property is at immediate risk of structural damage, that the problem will double in cost if left another month, or that they have a special price available today only.
Damp is a serious issue, but it is rarely an emergency that requires same-day commitment. Genuine professionals give you time to consider your options and are comfortable with you seeking a second opinion.
Diagnosing Rising Damp Everywhere
Rising damp exists, but it is far less common than the damp proofing industry would have you believe. Condensation accounts for the vast majority of damp problems in UK homes, and it does not require chemical treatment.
Be suspicious if a surveyor diagnoses rising damp in every room, particularly in:
- Upper floor rooms — rising damp cannot affect anything above the ground floor
- Properties built after 1875 — most have an existing physical DPC that rarely fails completely
- Rooms where windows show heavy condensation — this strongly suggests a moisture and ventilation issue, not rising damp
Refusing to Explain Findings
A competent surveyor should be able to explain their diagnosis in terms you can understand. If the person inspecting your property:
- Uses jargon without explanation to sound authoritative
- Becomes defensive or dismissive when you ask questions
- Cannot explain how they reached their diagnosis
- Won’t show you the evidence for their conclusions
Then there is a good chance they either lack the knowledge to carry out a proper assessment or are deliberately keeping you in the dark.
No Proper Survey Report
A verbal summary of “you’ve got rising damp, it’ll cost X to fix” is not a survey. Legitimate companies provide a detailed written report that includes their findings, moisture readings, photographic evidence, diagnosis, and recommended treatments. This report should be yours to keep regardless of whether you proceed with treatment.
If a company won’t provide a written report, ask yourself why they don’t want their diagnosis documented.
Cash-Only Demands
Any company that insists on cash payment only, refuses to provide a proper invoice, or asks for large upfront deposits before work begins should be treated with extreme caution. These are classic signs of companies that make it difficult for you to seek redress if things go wrong.
No Guarantee Documentation
Reputable damp proofing work comes with a written guarantee — typically backed by an independent insurance provider. This means that even if the company ceases trading, your guarantee remains valid.
If a company offers only a verbal guarantee, or a “company guarantee” with no insurance backing, your protection is essentially worthless if anything goes wrong.
Red Flags Checklist
Watch out for any of these warning signs:
- Cold calling or door knocking — legitimate specialists don’t need to canvass for work
- Free surveys where the “surveyor” immediately starts selling treatment
- No visible branding on vehicles or uniforms
- Reluctance to provide references or examples of previous work
- Quotes that seem remarkably cheap — substandard materials and poor workmanship cost more to rectify later
- Quotes that seem extremely high with pressure to accept immediately
- No clear business address — just a mobile number and a website
- Demanding payment before work is completed or refusing to provide staged payment options for large jobs
What Legitimate Companies Do Differently
Professional Qualifications and Memberships
Trustworthy damp proofing companies employ surveyors with recognised qualifications such as CSRT (Certificated Surveyor in Remedial Treatments) or CSSW (Certificated Surveyor of Structural Waterproofing). They are typically members of the Property Care Association (PCA), the industry’s leading trade body.
Written Reports and Clear Communication
A good company provides a comprehensive written report detailing every finding. They explain the diagnosis clearly, outline all available treatment options, and give you time to make a decision. They welcome questions and are happy for you to seek a second opinion.
Insurance-Backed Guarantees
Reputable firms offer guarantees that are backed by an independent insurance company. This means your guarantee survives even if the original company goes out of business. Always ask to see the guarantee documentation before agreeing to any work.
Transparent Pricing
Legitimate companies provide detailed, itemised quotes that break down exactly what work will be carried out, what materials will be used, and what the cost covers. There are no hidden fees and no pressure to accept immediately.
How to Verify a Company’s Credentials
Before committing to any damp proofing work:
- Check PCA membership — search the Property Care Association’s directory at property-care.org
- Verify insurance — ask for proof of public liability and professional indemnity cover
- Read independent reviews — check Google Reviews, Checkatrade, or Trustpilot
- Ask for references — reputable companies happily provide previous client details
- Check Companies House — verify the company is registered and note how long they have traded
- Request guarantee details — confirm the provider is a recognised insurer
What to Do If You’ve Been Scammed
If you believe you have been the victim of a damp proofing scam:
- Document everything — keep all paperwork, photographs, text messages, and emails
- Contact your local Trading Standards office to report the company
- Seek a second opinion from an independent, PCA-registered surveyor to assess what work was actually needed and whether the work carried out was adequate
- Contact your bank — if you paid by credit card, you may have protection under Section 75 of the Consumer Credit Act
- Leave honest reviews online to warn other homeowners
- Consider legal advice if the sums involved are significant
