Posted 21 March
Came out in April 2024 to fix a dripping extractor fan - cost was high but seemed to fix the issue. By winter it was dripping again, water collecting in a bend in the duct. Got them to come back Jan 2025. They tried to tell me it was coming from a leak in the roof & quoted £6k for a new ridge system! One of them up-ended the duct in the loft, sending loads of dirty water down into the bathroom through the fan. In the end got a proper roofing company in, who said the issue was condensation. Cost just over £300 to shorten the pipe and do minor repairs, no issues since. Will avoid HB5 in future.Verified reviewerJob location: IG6Response from HB5 Damp Proofing Timber Preservation Specialists Limited

HB5 came out to check what work needed to be done. They were desperate to get in and out, despite me asking them to check the whole house. Immediately told me we’d have to rip everything down and start again. I got a quote through from someone else at the company, going off just a few photos, for £22.5k. TWENTY TWO AND A HALF THOUSAND POUNDS. Genuinely it made me sick with anxiety for a few days. We got two other companies out who have said almost all the work recommend to be done by HB5 was not needed - quotes were less than £2k from elsewhere. Absolutely sickening behaviour from HB5. AVOID.Verified reviewerJob location: CR2
