Richard came and gave an initial quote, came back with sample materials and answered all our questions. His knowledge is extensive and reliable. The quote he gave was correct. The work he and his colleague did was thorough, precise and well executed. No additional costs, no time delay. Good Gardening Int is much more than just a building / gardening / landscaping company. Their knowledge is their passion. Have a look at their website. Highly recommended.

My career in roofing began in 1978, predominately on new build developments. In 1987, although continuing with the new builds, I began to branch out into domestic roofing. This included re-roofs, extensions, repairs and leak investigation. Alongside this, in 2010 I took a Contracts Manager position with a national roofing company, In this role I am responsible for the labour and materials required for various developments in the South East. It is also part of my role to oversee the customer service team. My contacts within the industry enable me to obtain very competitive prices on materials. I also have a large labour resource to carry out even the bigger jobs.

AVOID Adil is a smooth talker who hasn't got a clue about work in the industry. Employed to refurbish a full house. A SUMMARY of issues follows. 1 - Plastering done is uneven. 2 - Did not allow plaster to dry before painting walls so already peeling off. 3 - Found number of areas where holes had been left, and had these not been pointed out would have been left. 4 - Wood not sanded before painting, incl. new skirting boards. 5 - Threats when I refused to pay!

There isn’t enough space on here to describe how happy I am and stress free Rob and his team made the process. I had a major extension to the rear and side of the home which meant I wasn't able to use the bottom area of my home at all. Rob and his team took care of everything and also provided so much extra help all the time any time and keeping up with the consistent service is truly unmatchable. I’m very happy with the work, the finishing and everything else. Choose Rob and his team and you can’t go wrong

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

Did a fabulous job on my back yard concrete patio which was crumbling in places and needed levelling. Also suggested adding another step to a rather steep step in place already which made perfect sense and he did a great job with that too. Took 1 day and sent photos of the site after work. Very impressed and very happy with the outcome. I recommend this company and will be using them again on other jobs in the future.
