Bathroom Fitting- 10 Jul 2026
I am always a little nervous having to hire people to do work around the place following a couple of very bad experiences in the past. This was a superb job from start to finish! I couldn't recommend them highly enough if you are thinking of having some work done. They kept in touch along the way, did what they said they would do, were friendly, tidy and Antony made a wonderful job of the bathroom refit. I definitely wont go anywhere else now.

Bricklaying- 27 Apr 2026
Absolutely disgusting, said i was a FXXKING nit picker, garage not squared, layed block to the outside of one corner and inner at the other corner, joke. Used the bricks for the final wall plate to fill gaps in wall instead of cutting blocks. Wall leaning, even admits this. To many pictures to put on here, this is just one. I only realised this after I let him go, at a cost of 300 for the day. If he replies to this I will post all of the photos for him to see.

Latest review:
Dafydd and his team have fitted a new welsh slate roof on part of our farmhouse, built a rear retaining wall, fitted surface water drainage to the rear of the building and rendered one of the two gable end walls in lime mortar. The jobs have been carried out to a very good standard and the workmen have been excellent in both carrying out the work and looking after the property whilst working there. They still have one gable wall to complete but due to weather conditions and the use of lime mortar this will be down when the weather improves. Whenever I have discussed any part of the work they have been quick to react positively. Overall really satisfied with the work and will be hiring them to fit new concrete floors inside the house and Dafydd has already organised a visit from a heating engineer to give a quote on central heating. One final point, the financial cost of the work completed has come in just as the initial quote stated which was very welcoming given scare stories you hear of every increasing bills. No such problem on this job and overall very pleased with Dafydd Lloyd's work. In my experience there a good friendly professional firm to hire.

Conversions - General- 17 Aug 2017
I chose Phil of Build-it because of the prompt reply and his quick assessment of the of the work required. He came in with a competitive price and he gave us a positive feeling that he would be able to complete the job on time and to the required standard. Phil and his small team started the job when promised and completed the work within the time they said. All the work done was to a very high standard and they left the job each day clearing up after them selves. I would certainly use them again if the need arises and would recommend them.
