My name is Akos, I am originally an architect but I have a company called Zebra Services here in the South of England including South London. I do a lot of things by trade but my favourite occupation and our specialty is roofing, guttering, chimney and decorating, and painting, this includes minor plasterboard work, doors, skirting boards etc. But I wouldd rather have them talk about what others think of us: Akos and his colleague that worked on our house were thorough professionals and took great pride in the work they do. Honest, on time, and always thinking on their customers' behalf. He will be my first call if I have anything else that needs looking into around the house. Ahmed, Putney The work was done thoroughly and within the agreed time. Very polite people, no hanging around on phone calls, cleaning up after the job. A pleasure to have Zebra around. Will definitely use them again when necessary. Christian, East Grinstead Akos did a good job on my summer house. Plus he was punctual, pleasant, hardworking, quick and sensibly priced. What more could one want? Would happily recommend him. Alice, BN7 Akos was excellent from start to finish. He is a perfectionist and a very hard worker. He worked through the rain to complete the job on time. He did excellent repair work on a highly damaged chimney stack and repaired gutters. Would definitely use him again. High-quality work and is a very pleasant man. Christopher, TN21 Akos did an excellent job in very unpleasant conditions and I couldn’t be more pleased with the result. Definitely intend to use Zebra again. Keith, East Grinstead Akos was charming and diligent. His initial inspection was detailed and his subsequent work was quick and neat. I will be using him again Martin, Brighton Akos fixed everything for us. He is an excellent tradesman. Highly recommended. Timothy, RH19 Absolutely brilliant job. Really good fair honest guy and very good workmanship. Will definitely use him again for anything roof/gutter related and would recommend him. James, KT6 Thanks for carrying out such good work in my flat at a reasonable rate. I will definitely have you back again and recommend you to friends and family that are looking to have work done. Thanks again. Clyde, Dartford Akos proved to be a hugely competent craftsman who completed our roof and guttering repair on time and within a reasonable budget. We have no hesitation whatsoever in recommending him. Phil, Forest Row

Started promptly but the job, expected to take just over a week, dragged on for over 6 weeks with repeated delays and requests for additional interim payments. Communication became poor and the work was left incomplete. I eventually had to hire another contractor to finish it, costing me an extra £1,450. Despite acknowledging the situation and promising to reimburse the additional cost, no payment has been made.

An itemised invoice was provided and updated after any change so I was always aware of my costs. The team he had working on my job were professional, punctual and very polite. The work performed was excellent, I am extremely pleased with the final product and would definitely use them again and I recommend them wholeheartedly (which I have already).
