Unblocked drains

We had have a terrible blocked kitchen drain since moving in to our house last year so I called Maintain Drains. I liked the fact that it was fixed price and no call out charge. They said on the phone what it would cost and someone turned up at 1pm. Unfortunately, he was unable to lift the manhole cover in our drive by himself and said that he would be back with the boss later today. It was getting towards dinnertime so I called to see where they were. They soon arrived and fixed the drain and offered various solutions as to how to stop it happening again. Even better, they charged me less because I had waited a bit. I thought they were polite and answered my questions in detail. I would recommend them.
