Could not praise the service highly enough. Called and spoke to friendly staff and arranged a site visit Drain doctor Mark Graham turned up at exactly the time they said he would. He gave me a price and set to work on the drain This was a very tough drain to clear I have had meany firms over the years come and attempt to flush it through and they got it half working, Mark persisted even after I had thought it was not going to clear. and hay presto all cleared and sorted :-) drain has never worked better. Excellent work and communication by all the staff at Drain Doctor, Especially Mark Graham. Could not be more please with the service. Thanks for the hard work and persistance Mark you're a Star.
