Carpentry- 21 Aug 2026
I would never recommend this joiner. He quoted £45 per hour and said there would be himself and another joiner. He turned up the first day with a lad and had to explain to him how to lay the wood! He then left leaving the lad on his own just piecing the wood together. The next day 2 lads came but he was only there for a few hours. The 2 days cost me £1200 and very little was done. The first 2 photos show the part of the flooring laid by my son in law who is not a joiner and the others the edging pieces done by the 4 hrs the joiner worked and the 2 lads. I then paid him £450 the next day. He asked for £650 but we disagreed on that price and he reduced it. Part of the floor had to taken up as it had been laid wrong and he took 15 pieces of wood away to resize to fit in the space left. I am still waiting for those 15 pieces. The 3 days cost me £1650 and I now have to find someone to finish the second half of the room.

Alan created a kitchen diner space for us by doing several things: He widened the doorway, installing lintel brick up two existing doorways, created a window with lintel. He has been a massive help, his hard working attitude and excellent level of work has enabled me to not worry about the job and instead get a head start on the other bits. In short - exactly what you need from a professional tradesman.

Extensions- 13 Nov 2022
Excellent from start to finish I can't praise Dave and his team highly enough. Great communication before and throughout the work. Comprehensive estimate to start with laying out every detail of the work. The work started on time and they worked every day till the job was complete. Dave was happy to add extra jobs as we went a long and always had great ideas to make the finished extension even better than we imagined. Dave made what could of been a very stressful experience as easy as it could be. The job was left very clean and tidy at the end of every day. I now recommend Dave to everyone. Dave is coming back next year to rebuild our garden wall and I'm sure we will be having more work done in the future. I have never known anyone who can do literally any building job to such a high standard.

Conversions - General- 22 Aug 2025
I hired Chris to install an RSJ, and I couldn’t be happier with the service. From start to finish, communication was excellent — he took the time to explain the issues uncovered during the work and talked me through the best solutions. His professionalism and problem-solving skills really stood out, especially when dealing with the poor building standards left behind by a previous builder. He also took care of building control and ensured everything was signed off properly, which gave me complete peace of mind. His team were polite, professional, and worked efficiently. The job was completed in a timely manner and with real attention to detail. I’d highly recommend Chris to anyone looking for reliable and skilled builders — a true professional you can trust.

Bricklaying- 18 Jun 2026
Shaun (the owner) came promptly for a site visit and explained very clearly the solution and sent a detailed quote 24 hours later. The quote was the best from a local professional builder who provided a formal contract and company documents and inspire total confidence.The job was about taking down the garden wall pushed over by several big trees cut but with stumps left in place and with a very big tree at the distant end of the wall. We mutually agreed the starting date which we kept flexible to account for weather changes. Shaun and his team did an excellent job on taking down the old wall, dealing with the very large tree stumps, dealing with a challenging issues around a big tree and building the new wall with pillars and caps. They removed all the rubbish and washed the pavement a very tidy job. .As promised Shaun came back two weeks after and mounted back the wood panels. He is a very good manager for the team and they were all very respectful. Very pleased, would hire again.
