“Had an overflowing blocked drain at the side of my house – rang around a few drain companies in Bristol that couldn’t come out on the day, rang Trent’s and they arrived within a few hours to clear it. Really friendly guys turned up and didn’t charge the earth either! Highly recommended.”

Jody Artist

”Would definitely recommend Trent’s and use them again. I had a blocked drain with an access problem. They were recommended to me after Dyno Rod and another firm couldn’t resolve the problem. Very helpful from the start. Really responsive, quick and good communication throughout.”
