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.

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.
