Highlights
"Firstly to say this work was carried out last Summer so have been late in submitting but needed to recommend. Ross and his team have carried out damp work in our old house on a number of occasions and their work has always been first class. We contacted Ross in about March 2025 for some damp work in our kitchen, this lead to far more work than anticipated. Throughout the whole process we were kept informed of timescales and additioanl cost associated with unfortunately finding cracks in the exterior of the walls which we had been forewarned about may happen after the rendering was removed."
"We had rising damp on and around our chimney and he has sorted the damp , replaced skirting , some floor boards and replastered the walls. James has done great job and comes throughly recommended."

Smart checks
Before you hire a builder
Never pay a large deposit up front — agree a staged payment schedule tied to completed milestones, and hold a small retention until snagging is done.
Get it in writing: an itemised quote with scope, materials, start and finish dates, and how any changes (variations) will be priced.
Be wary of a cash-only price or pressure to start tomorrow — both are red flags for an unaccountable job.
Ask to see a portfolio of completed work like yours, plus recent references you can contact.
Check the credentials and registrations that matter for this work — and that they are current.
