Conversions - General- 7 Apr 2019
Dean has been truly remarkable throughout the whole process. Following the initial visit he had an excellent grasp of the project and was able to recommend the most practical approach to the works while having factored into consideration our original scope for the new garage conversion. It was very apparent from the outset Dean’s building experience and knowledge compared to other contractors (notably an excellent eye for detail). Most importantly Dean was very earnest yet competitive with his approach, his pricing was transparent and he provided a clear breakdown of the scope and project timeline which was greatly appreciated. Once agreed the job itself was undertaken in an expedient yet structured manner. Dean works very swiftly and was extremely dedicated (almost machine-like)! He was true to his word and the project was completed within the agreed timeframe, in fairness with a number of days to spare. He placed careful choice with his sub-contractors and likewise they performed in a similar manner. The end product is that we were handed a high quality downstairs bathroom / utility room with general piece of mind given the professional manner and approach to the work. Sincere thanks to Dean for his efforts, I would highly recommend him for any project, big or small!

Landscaping- 23 Jan 2025
CNH did a great job on the bridge of our busy church in central Guildford. We had lots of positive feedback from our parishioners and they matched the colour of the resin bonding very well to the aesthetic of the building. The end result was that it looked like it had always been there, apart from the obvious newness of the surfacing.

Extensions- 2 Nov 2023
I asked Jamie and his team to help me erect my garden room this autumn and I could not be happier with the result. Jamie understood the brief immediately, was clear about pricing and responsive via text. He and his crew turned up on time, worked hard to offload and build the structure and were good humoured and polite to boot. They clearly take pride in their work and I wouldn't hesitate to use them again.

Groundwork & Foundations- 22 May 2026
John did a fantastic job with the groundworks for our new 150sqm block driveway. He priced keenly, started quickly and was on-site consistently every day for the week. Really skilled with the digger, good at dealing with the neighbours and always fun to talk to. Some aspects of the job changed based on what the dig uncovered, but he was pragmatic and ultimately left me feeling that he just really wanted to do a good job as if it was his own. Highly recommended - 10/10.
