Plastering- 7 Nov 2017
Bernie provides outstanding customer service. He takes great pride in his works and has a large understanding of skills that he is more than happy to share. He worked extremely well on leveling the fireplace to the correct height and the job was done in great timing. He had great availability for the job and I was so pleased that it was done urgently. He showed me some of his other works and it was a truly magnificent work of art to say the least and I would highly recommend him to friends and family.

Carpentry- 19 Jun 2019
The job actually got bigger as the time went on, once I’d removed the old wardrobes the walls needed plastering and the laminate flooring needed extending, so a “simple boxing in job” became a nightmare! Dan’s professional approach was unquestionably and his ability to be able to fulfil all of the requirements was brilliant. The room and surrounding area was left immaculate at the end of each day and he was always prompt arriving in the morning. The finish of the work was 1st class and I can’t recommend him enough, if any one would like to see his work, then their more than welcome to view.

Extensions- 19 Apr 2023
Avoid Phil and KPM Construction (South) Ltd like the plague. My experience with Phil was beyond the worst I’ve ever experienced with a tradesperson. I’m sure Phil will respond and attempt to place blame on me. I understand from other customers and trades he uses that they will say similar to me. The job started in July last year (was meant to be finished within a few weeks) was never finished and it was only a month ago that we finally got our money back - probably one of the lucky ones. He has caused a huge amount of stress and wasted time to us. We chased him many times and he would ignore us for weeks on end, coming up with numerous excuses of why he couldn’t do the work, including blaming us. His lack of professionalism is beyond me and we had no choice but refer him to trading standards during the process. I’m just pleased we were able to find another builder which has provided some perspective in terms of how truly awful our experience with Phil was.

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.
