"I cannot upload a picture of the work completed as it was work carried out at two of my rentals (flats) where I have tenants. I have also used this company at my family home. I have found him exceptionally professional and would never hesitate to use him again and have recommended him to my colleagues. His work ethics are second to none, I had to call him out to fit a fire door urgently, and he worked the bank holiday to get the job done, without extra charge. I have also used him on another of my flats and no job is too small he has helped me out when needed, and if he can’t fit it in in his daily working hours, he has worked the weekend. I would not hesitate in recommending this company and know that any future work he obtains will be fulfilled at the highest standard with excellent communication skills ."
