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.

Extensions- 17 Aug 2021
Long overdue feedback, the pictures/ decor has changed since below but just wanted to share the feedback. Crew are super, we’re with us through pandemic and worked tirelessly when materials were short and jobs were delayed.. simon is a fair guy, busy but still gives you time to share his creative side. Nothing was too much of a bother. Workmanship is A* and I have huge OCD. I would recommend Simon and team to anyone. And we spent a fair amount of money, everything was reasonable priced with no surprises. With Covid, the whole team were mindful and with a short delay due to restrictions got back on track.. every single one of the team were nice/ hard working and rarely do you find a team that can do the demolition yet have the finesse of the final touches. Sorry for the delay in feedback..

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.
