Although tiling isnt rocket science and most people to a certain degree can manage to
tile to some extent their is an aweful lot more to go on than the clients think. You have to wonder how many diy jobs are done with the wrong sticky etc. Leading to the next thing of, well, how important is alot of it, different sticky, tanking etc. To a client, tanking is usually a thing they have in their heads we are trying to add on and not needed, and in most cases isnt really. When they've seen a tub down B&Q for £5 Add and grout in 1 and then our gear comes to £150 it must get people thinking, and I understand to a certain degree. Ceramic tiling will never be thought of as as much of a skilled trade as plumbing because people understand it, pick up a
tile, whack it on a wall, and most have had a bash at some point in their life, usually people who have, dont mind paying if they've had a mare. People will pay alot more for a job they dont understand as much.
