Highlights

“We did a rear extension and internal reconfiguration of our lower ground flat in North London. Ali was incredible from start to finish. Ali's quote was the most competitive we received and we obtained great references from his previous clients. His team are friendly and Ali was on-site almost every day to oversee the work. Ali was easy to reach either by phone or Whatsapp. The project came in on time and on budget. I would have not hesitation in using DAS again or recommending them to family and friends. If you're looking for a reliable builder, look no further.”

“Ali and his team were fantastic. Really professional and updated some very old and complicated plumbing. In fact, their tidy plumbing work has given us a whole new room in our attic with water tank removed, cylinder moved and pipes sorted out. Great job. Have already asked them to come back next year to refurb our bathrooms.”

This trade isn't licensed in the UK, so anyone can set up. TrustMark is the only Government-endorsed quality scheme for work in and around the home - check whether they're registered, or find a TrustMark-registered business.

Check the TrustMark register
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.
