I was very impressed by the work of Ryan and his team. They attended promptly. Used a metal detector to locate a manhole cover hidden two feet under soil on a hill in my front garden. Having located the blocked drain they cleared the blockage quickly and cleanly advising it was caused by flushing baby wipes etc down the toilet.

He also advised I could pay for a more extensive cleaning of the drainage system and CCTV report at a later date if I wanted to. Two previous drainage experts were unable to locate the problem. One offered to conduct an expensive survey. Ryan saved me a lot of money.

Ryan and his colleague did a great job clearing the blockage in our drains/sewer. Unfortunately, a rat popped it’s head up while he was working and there were signs of a rat infestation which will need further investigation. I have no hesitation in recommending Ryan and will book him for the future work that needs carrying out. What was really commendable was that he didn’t charge for the job as he is doing such work free of charge during lockdown for the over 65’s and vulnerable people. A very nice man.

Highly recommend Ryan in all aspects of his work. What we thought was a major problem turned out to be a blocked drain which Ryan cleared within a couple of hours. One very happy customer and would definitely use C4 drainage again in the future.
