  • Renovation including removal of chimney

    10Verified Review

    We had a fantastic experience with Horizon Builders, and in particular Stuart and Danny. They were professional, knowledgeable, reassuring, tidy and easy to communicate with. Excellent time keeping and all the workmen worked as a unified and friendly team. They were highly skilled and did an excellent job which included removal of an entire chimney, a new roof, plastering and boarding and outside drainage. We would highly recommend them.

    The directors, David Gee and Stuart O'Sullivan, were always prefoessional and a pleasure to do business with. Their team was hardworking and always left the premises clean and tidy each day. They carried out our fencing and paving to an excellent quality and we heartily recommend them; in fact they were highly recommended to us by two of our neighbours which is why we opted to use them inspite of having to wait a while before they could start our job!

  • Neighbour's LandScape work

    10Verified Review

    Having watched as how they've carried out Garden Landscape work at our neighbour's place, I couldnt stop myself in giving them a review. They are the best. It's a complex and difficult work but they've completed the work very effieciently and within the time. Also, they've ensured that my side of the garden was clean as well..After watching how they've done, I've requested them a quote. for similiar work ( water collection @ garden and ensure that it's channelled into the water pipe). And once I have some funds, will initiate the work They are top class.
