Bricklaying- 22 Aug 2022
Adam did an excellent building job, both brick work and carpentry, at the end he cleaned up and removed all the debris. What happened Adam started on Tuesday 16th August and expected to complete the work in 1 day, but he had to return the following day. Wednesday he worked till mid-day, leaving to work on another job. Thursday he didn't turn up, same on Friday. Eventually I managed to make contact with him and he said I will be there on Saturday. So on the Saturday we expected him at 8 to 8.30am. I rang him at around 9.00am to say where are you, he explained he had been working on another urgent job, but he would be with us around 9.30am. He arrived and by 11.30am the job was finished. We have a small well in our back garden, the roof had collapsed, it needed a large piece of plywood with tiles on the top. Adam said I will bring you a piece of plywood at no charge, either tonight or during Sunday, we felt very happy about the whole proceeding. Of course over the weekend no Adam arrived no plywood nothing, no email, or answer to my phone call. So finally on Tuesday we went out and purchased a large piece of plywood. So there you have it a very good workman, but keeping his promises needs to be considerably improved.

Groundwork & Foundations- 1 Oct 2024
It was a complex job requiring the removal of an earth bank, ground works to include reinforcements to an independent engineer's specification, and re-erection of a boundary wall in a locally listed area against a busy road. We had some problems during the works but all were resolved to mutual satisfaction and with good humor. The end result is a high quality, solid wall of which Dave and his team should be proud

Painting & Decorating- 10 Jul 2024
I recently had the pleasure of hiring Daniel to paint the ground floor of my house, including the kitchen, hallway, and living room. Not only did he do an exceptional job with the painting, but he also took the time to fix issues left over from a previous plasterer, all within the price we agreed on. Daniel truly went above and beyond my expectations. His attention to detail and dedication to delivering high-quality work was evident in the finished product. The walls look fantastic, and I couldn't be happier with the result. If you're looking for a reliable and skilled painter, I highly recommend Daniel.

Landscaping- 17 Mar 2024
Very pleased with the work undertaken by Centurion Building Services. Mark and Neil were very professional and courteous. They arrived early each morning and worked in very bad weather to get the job completed. Ben was on hand to oversee the job and to complete the pointing. We could not have asked for a better team of builders. They cleaned up after every days work and left everything neat and tidy. These guys are the best!! I would certainly recommend them and they are now my 'go to' builders. Thank you Grant, Ben, Mark and Neil for a superb job that has certainly enhanced the kerb appeal to our house.
