END_FLOW
DC Construction transformed our tired old garden with a full patio relaying, some decking and turfing the patchy bits. They listened properly to what we wanted low maintenance wise and suggested sensible materials.
The team were punctual, polite and really respectful of the house no boots inside and cleared up brilliantly each day. We’ve had a few barbecues since and it’s held up through the wet autumn no problems. Their advice on drainage was spot on too. Relieved we went with them instead of the cheaper quote we had. Very pleased indeed.
