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! ????
