What to check when hiring damp proofing / waterproofing in Australia
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.
- Trade and building licensing in Australia is set by each state or territory. Check the relevant regulator (e.g. NSW Fair Trading, QBCC in Queensland, VBA in Victoria) that the contractor holds a current licence for the work type and value before you hire.
- For larger residential building work, confirm the contractor carries the home-building / domestic-building insurance your state requires before you pay a deposit. It is what protects you if the work is left unfinished or defective.
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 tradesperson’s public evidence above.
Verify before you hire
- Waterproofing is a licensed trade in Qld (QBCC) and forms part of licensed building work elsewhere: verify the licence, especially for wet areas and below-ground work.
- Internal wet-area waterproofing must comply with AS 3740, and external or below-ground waterproofing with AS 4654: ask which standard applies and how it's certified.
- Look for manufacturer-accredited applicators, as that's usually what backs a long product warranty.
- Confirm public liability insurance and a valid ABN on the ABN Lookup (abr.business.gov.au).
Warning signs of a dodgy tradie
- Promises to 'cure rising damp' with an injection but won't diagnose the actual moisture source first.
- Waterproofs a wet area with no reference to AS 3740, or no licence where required.
- No manufacturer-backed or written workmanship warranty.
- No public liability insurance, no ABN, or a large cash deposit up front.
Questions to ask before you hire
- Do you hold the waterproofing licence my state requires?
- Which standard applies (AS 3740 or AS 4654), and how is the work certified?
- How did you diagnose the cause of the damp before quoting?
- Are you an accredited applicator, and what product and workmanship warranties apply?
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.
