Roofing (Pitched)- 24 Mar 2026
I recently had a new roof installed on my garage and couldn’t be happier with the result. From start to finish, the roofer was professional, reliable, and clearly very skilled at what they do. They took the time to explain the process, answered all my questions, and provided a fair and transparent quote. The work was completed on time and to a good standard. The attention to detail was excellent, and the finished roof looks fantastic—solid, neat, and built to last. They also made sure everything was cleaned up properly afterward, which I really appreciated. It’s not always easy to find someone you can trust for this kind of work, but I would absolutely recommend them to anyone needing roofing services. A great job all around.

Rhys and his team have good skills and quality on all the extension works including big/long steel beam installation, extension connecting to the existing structure, complex loft conversion and architectural curve hung ceiling. For the internal decorating, they completed a beautiful bathroom for us. The staff were polite and friendly and also provided technical suggestions to optimise the design time to time. I would recommend RJB for similar size extension construction projects and decoration work.

Conversions - General- 4 Mar 2021
I have worked with a few builders during my time renovating properties and I can genuinely say Pat and Ed are two of the most professional, knowledgeable, hardworking and honest tradesmen I have come across. They quoted me a competitive price for my phase 1 works which included labour, all materials, skip hire, structural engineer and building control costs. I asked them to manage all aspects of the phase 1 renovation as well as organise the structural engineer and to deal with building control. The work included taking everything downstairs back to brickwork and replastering with bonding coat and multifinish plaster, replacing/replastering ceilings, building new stud walls, resizing window openings, removing parts of a chimney breast and knocking through between living room and dining room. They carried out all the work quickly and professionally and always went the extra mile to help out where they could. I was extremely happy with their work and would highly recommend them to anyone.

Bathroom Fitting- 14 Jun 2026
George came to my rescue after what initially seemed like a straightforward bath replacement turned into a much bigger job due to unexpected floor damage underneath. He was very reliable, knowledgeable, trustworthy, fast, thorough and incredibly easy to deal with. He kept me updated with photos/videos, explained everything clearly and acted quickly to find the best solutions. When we discovered bigger issues, he strengthened the floor properly to get the job right. He also went above and beyond on several occasions, carrying out additional jobs free of charge, including replacing a faulty light switch that he noticed himself. Despite the unexpected extra work, he completed everything quickly and with no fuss, finishing ahead of schedule and to a high standard. Finding contractors like George is rare. I was so impressed that I've already asked him to carry out further work at another property. Excellent work – highly recommended. I will definitely use George again.

Landscaping- 17 Mar 2020
WOW!!!! Having previously being ripped off when having my patio laid and having to suffer increasing frustration and disappointment with it for over 9 years or so I finally caved in and looked to have it redone. Keith was a revelation. He listened to my tale of woe and asked pertinent and intelligent questions to understand what I actually wanted when he came to do the survey. The quote he produced was quick, detailed and presented me with options for the ideas I had in mind. It was also a very fair price for the work required and involved. He produced a contract which put my mind at ease somewhat and protected us both. He was punctual, honest, polite, knowledgeable and hard working. His work was to a really high standard and quality. Every day he left the site as clean and tidy as could be under the circumstances. He communicated well with us throughout ensuring we knew what he had done, what was still to be done and how and when he was going to do it. The final finished patio is fantastic, I love it. He started when he said he would and despite some vicious weather he finished ahead of schedule. If you want a great job for a fair price completed by an honest hard working grafter and tradesman then Keith is your man. So much so that he will be the only person I will approach to do any further works I may need in the future. I wouldn't hesitate to recommend him to anyone. Five star quality. Top Man

They are a very professional team who kept us well informed and are also very efficient and like to keep a tidy working environment!

I needed one wall of living room plaster called Craig and he made the whole process so easy, he came round to give me a quote. Compared other workmen and craig was very competitive, he made the whole process easy, I was going to decorate the room myself but Craig put me at so much ease, that I gave him the whole job of plastering and decorating the room. I was worried that I wouldnt get the room done by Christmas. He promised that he would get it done. He was very prompt and the job got completed in the promised time frame. And I was very happy with the result

Peter recently built me a bespoke counter/pens for my Grooming shop, it was a complex job and I needed specific requirements to meet covid guidelines, he happily met them all, was punctual, professional and a very friendly trustworthy guy. He answered a million questions with a smile and bent over backwards to get me exactly what I wanted within my very tight deadline and he stayed within my budget all in these challenging times. I would absolutely recommend Peter to anyone. My team and I are thrilled with our new counter. Thank you Peter and your team
