The work completely was of a very high standard with immaculate attention to details. Jerry was punctual from the survey stage to the end of the work. He sorted little snags with the wall, separated the work area with a plastic sheet so the dust was minimised. After each day, my home was left clean and the job was progressing well. The end result looks great and no issues so far. I would recommend them 100%

Zoltan was great. He took the time to design and plan with us, had a lot of patience for working out the detail... he was very clear in giving us timing brackets and delivering within that time. He loves what he does, and that is very visible in the quality of the carpentry and joinery he delivers. We would definitely recommend him to anyone as we are very happy with the results.

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! ????
