Blocked drains McCanns Drains called from internet, came put pressure hose down drain but failed to clear drains. Left mess of sewage on path. Stated that they would have to dig up front drive and locate valve. Total cost £1350, they took £700 with rest on completion wife read reviews, all bad so we contacted the company and and cancelled job. They stated that they would charge £135 for failed attempt to solve the problem. Returning £565 into our Bank in 3/5 days. We then got Dyno Rod out for a 2nd opinion. They fixed blockage cost £144 with a 3 month guarantee. Worried that McCanns could be using this tactic on the old and vulnerable people.
