Highlights
"Refubished my 3 bed house new bathroom new kitchen central heating rewire wood floors k rend outside new windows etc very happy to recommend not the cheapest but you get what you pay for finish was top notch !! Clean and tidy nothing was too much for the team any probs were sorted will use again."
"We couldn’t be happier with the builders who completed our bathroom renovation. Their workmanship was absolutely immaculate, with incredible attention to detail in every aspect of the finish. Everything was installed perfectly, from the bath and shower door to the tiling and fixtures. They were professional, tidy, and respectful of our home throughout the project, keeping the space clean and organized each day. The final result exceeded our expectations and truly feels like a luxury bathroom. Highly recommend them to anyone looking for quality craftsmanship and a flawless finish."

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.
