Hi my name is Mansfield. I have been a bricklayer for over 30 years, I did 3 years as an apprentice back in 1986, since then I have worked on a number of building projects including industrial, commercial factories and large housing projects for the better part of 10 years after which time, I decided to go self employed, and built brickwork for every thing from simple small garden walls to 100 meter boundary walls , plus brickwork for all sizes of extensions domestic and commercial including all ground work. So it dose not matter how big or small your job is if it's brickwork decorative or plain or block work what ever you need I am your man for the job. I am efficient neat and tidy, I guarantee the best job first time in the shortest and fastest possible time at very good rates. most jobs I will do on a day rate but some larger jobs I may do on a price depending on the nature of the job. My daily rates are £200 for one man and for my self and a labourer £350.Thank you.

Bricklaying- 17 Dec 2024
They initially gave a fair price and a date and timeline that fitted with our needs. Subsequently they over ordered on the bricks so we had over 100+ expensive London bricks left over and they under ordered on sand and cement.(Luckily the shop took them back but we had to deliver them there) The job took far longer than they had said although the poor weather did not help much which could not be helped. The worst was that the wall was finished so that the latch of the gate could not be fitted as the wall was a bit too long! The wall looks good but their customer service and time given for job as well as ordering materials needs some improvements. They are pleasant workers, not rude in speaking

Bathroom Fitting- 2 Mar 2026
I can’t recommend him highly enough, in just three days, he identified and resolved my bathroom leak that could easily have become a much bigger issue. He took the time to thoroughly investigate where the water was coming from, clearly explained his findings and advised on the most sensible next steps before carrying out the work. From start to finish, his work ethic was exceptional. He arrived promptly at 8am every day and worked through until 6:00pm without a single complaint, no matter how demanding or time-consuming the job became. His efficiency was impressive but what stood out even more was the quality of the finish - the bathroom now looks brand new again. Professional, hardworking and meticulous in his standards, he delivered outstanding results in a very short timeframe. I wouldn’t hesitate to use him again or recommend him to anyone needing reliable, high-quality building work

Kitchen Fitting- 17 Nov 2025
We recently had our kitchen refurbished by Dumitru, and we couldn’t be happier with how everything turned out. He’s one of those rare builders who combines professionalism with real care for the details. He worked efficiently, kept the place tidy throughout the project, and always cleaned up after himself — which honestly made such a difference when living through a renovation. What I appreciated most was how supportive he was when it came to choosing the right materials. He guided us through the options without ever pushing, and his advice proved spot-on. The final result is exactly what we hoped for and more. If you’re looking for someone reliable, skilled, and easy to work with, I totally recommend Dumitru P.S. For anyone curious about the scope of the work: Dumitru changed our worktop, removed the old tiles and redid the flooring with laminate, installed a new cooker and hob, fitted a new sink, repaired the walls after the new boiler went in, and repainted everything. Top work

What experience do you have with similar extensions in Old Town?
