Hi, my name is Adam and I have worked in the building trade for the last 25 years. I started my own company January 2021 and have loved every minute. I pride myself on giving a very high level of service for the work that we carry out. Most of my work comes through word of mouth. Our main work is kitchen and bathroom installations. Being a company that can carry out all forms of building if your install is complicated or requires construction work we are able to carry out all works for you. If you are looking for a friendly, hard working company with a very good eye for detail then please contact us.

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.

Bricklaying- 9 Dec 2025
We agreed a start date for the work, and from the beginning communication was slow and required constant chasing. Alan sent me a full materials list, which I purchased on the understanding that the job was proceeding. As the start date approached, I repeatedly tried to confirm when he would arrive so I could organise my day and be available to help on site, as we agreed for me to b involved as a labour. Despite reading my messages, he stopped responding entirely. I sent multiple messages and tried calling several times over the course of a week and received no reply at all. The job never started, and I was left with purchased materials and a significant amount of wasted time. I cannot comment on the quality of his work as he never turned up, but based on the communication alone I would strongly advise others to be cautious.

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

Extensions- 8 Jan 2015
Phil handled all aspects of our extension build and completed all work to a high standard. He was great at keeping us informed of progress and quick to communicate any potential delays, ensuring that we always felt in the loop. He dealt with a number of issues that arose unexpectedly during the build and found solutions to all these problems, delivering the whole project within the agreed budget. We would have no hesitation in recommending Phil for all aspects of building work and have had him back already to carry out more work on other parts of our house. Most importantly of all - he's an extremely easy guy to have around your home - polite, tidy and totally trustworthy. Highly recommended.
