Bricklaying- 22 Oct 2023
I chose this trader because he was local and responded quickly and politely to my enquiry . He was also able to provide a detailed quote listing all materials and labour charges and the final bill was exactly as agreed. The job started on the day agreed and finished on time, the end result was high quality and I could not have expected better. A team who worked tidily and were thorough in clearing up. Very positively recommended, I would use them again without hesitation.

Repointing- 31 Oct 2019
Daniel Arrived on time for looking over the job and quoting. His attitude was very favorable in that he wanted to do a good job and was customer focused. He listened carefully to what was required, and we looked over everything together. He eagles eye and attention to detail then came to the fore, pointing out some other aspects not been seen beforehand being done respectfully. He simply explained while I have a mix ready to go it's not any more bother to fill in the extra's. We agreed a cost and a convenient time and day for him to return to do the work. He subsequently returned on time and completed the works, efficiently leaving everywhere neat and tidy, as if he's not even been there, except for the obviously repointing. While he was carrying out the works it became obvious to him that a better, more aesthetic finished job could be achieved, which we discussed and reviewed the plan of work. I am so very pleased with the result; it all looks good and all blends well together. Daniel is an amiable, cheerful person, clearly enjoys his work was keen, not only to do a good job but going the extra mile - above and beyond. I would not hesitate to recommend him.

Kitchen Fitting- 31 Jul 2019
Can't recommend this guy enough! Pat is a professional from start to finish. He came to quote me for a complete kitchen refit, within a few days he had emailed me a detailed quote and we agreed a date. My kitchen came with many unforeseen problems and challenges but Pat rose to them all. Aside from being a skilled carpenter and a skilled builder he is a great problem solver. He is reliable,trustworthy and very approachable. When I was getting stressed out he would calm me down and reassure me that everything would be ok. Sounds silly but my kitchen issues would have stressed a saint out! To summarise, my kitchen has turned out beautiful! Pat has done the work to a very high spec and gave it the wow factor! I absolutely love my new kitchen and am so happy that I chose Pat to come and do it for me. Look no further!!! Hope he posts my before and after pics on here and you can see for yourselves!

Roofing (Flat)- 22 Nov 2020
Peter and Rob were great, they reached out very quickly to arrange a meeting to see the work which another builder had completed messed up. They were able to present a reasonably priced quote soon after and completed the work in just one day working solidly from 9am to gone 4pm on a Saturday. The quality of the work was very good and they tidied up after themselves. Would definitely recommend their services and in fact we are engaging with them again on a few more jobs around the house.
