  • No.42687 Install approx. 4.25 metres of ACO between patio and the garage wall to prevent flooding.

    9.5Verified Review

    Workmen arrived on time. They were efficient,polite,neat and tidy. We are pleased with the visuals of the completed job but it is too early to say if the suggested work has solved the problem as insufficient rain has fallen since the job was finished. Our major observation is that the cost appears to be very expensive given that the job was completed in just one day.

  • Clearing a blockage from the kitchen pipes

    10Verified Review

    Absolutely brilliant job by Dan. He was onsite within 4 hours of the job being booked and had the blockage cleared in under an hour. He was professional and personable and the price was very reasonable. I would recommend and use again.
