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%

Fatjon / Tony and team did a fantastic job decorating my house, getting rid of damp and giving my front garden a completely new look. They re built wonky walls, rendered them and laid some amazing tiles giving an original Victorian look. Communication was excellent and there were no surprise / hidden costs at the end. All the guys at Bardhi construction were super friendly and extremely respectful of my house. They cleaned up every night and took great care of my property. I highly recommend :)

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.
