  • Drains and Septic tank work.
    I have no hesitation in recommending Clarke Contractors for drains and septic tank work. The repair to my septic tank and drains was carried out efficiently, to a high standard and completed very quickly. A good company.

    alled Clarke Contractors when we discovered a problem with our drains. Gareth took the time to understand our problem over the phone and came out to assess the problem on site in no time at all. As suspected Gareth confirmed our soakway had failed and discussed all of the options available to us. In the end we decided to fit a state of the art treatment plant. Attention to detail and quality of workmanship was first rate. He kept us informed all the way through. They handled all dealings with the Building Officer (they even commented about how tidy their work was). Extremely pleased with the end result and would highly recommend Clarke Contractors.

    First class technical advice given when a problem was found with our septic tank and soakaway. The advice was taken, no pressure from Gareth, and a new waste treatment plant installed. The work was completed quickly, professionally and with no fuss, the site was left neat and tidy. I would highly recommend this company.
