Craig got in touch quickly, gave me a rough estimate over the phone and answered all my questions. Surveyor arrived on time, gave instant quote. Price was good. Michael and (another) Craig turned up to do the job on the day, time given. Good, tidy job. Can't fault anything, from start to finish!! Would recommend!

George and his team are experienced builders, replaced my front door with a custom frame/sidelights and raising the floor level in the hallway quite quickly - in fact, they were the only who came next day, gave a quote straightaway and were ready to start in just couple of days. They also had all the necessary tools and materials, were ready to buy something additional quickly on the day - if further adjustments were required to fit everything as I asked. Thanks a lot for your help, guys!

Highly recommend. These guys did a fantastic job of constructing our pergola and decking. Very hardworking and reliable. The job was completed in the time frame agreed and to a very high standard. We would 100% use them again.

Hi, we recently had Florin and his team do some work on my Mum’s garden. He has done an incredible job and we are so pleased with his work. He was very friendly, polite and completed the job in a timely manner and to our requirements and very reasonable and good ideas and suggestions. I would have no problem recommending him and his team again and will do in the future if I know of anyone needing. Thank you for your hard work

Alex and his coworker from C&P General Construction Ltd did an exceptional job repairing and repainting my front door, 7 door frames and most of the skirting boards around my flat. They both are very friendly and are very good at being neat and paying close attention to detail. Alex offered a reasonable price and made sure they both took their time so it was done to a very high standard and to my satisfaction. I felt even more confident when Alex shared his professional advice throughout. Thank you Alex! ????

Andreas & Vladimiros quoted me exactly as I estimated for my toilet and bathroom jobs. Despite cheaper quotes, I trusted this father-son duo—they reminded me of my own dad. I supplied materials; they did the labor flawlessly. They worked tirelessly, always smiling, skipping breaks. It was a pleasure working with them. I highly recommend these top tradesmen and will definitely hire them for future projects. Ignore any low ratings—they don’t reflect their quality.

After initially posting for a small garden job at home, instead spontaneously requesting a quote to inspect the condition of a roof on a commercial property. Jesse recommended installing replacement rain goods. These works led to the discovery of a serious issue, that he and his team were immediately able to address, using incredibly high standards of workmanship, culminating in a substantial roof upgrade. Jesse and his team were professional, courteous and extremely tidy. I am delighted with the outcome.
