Frequently the people you buy if from (I got mine from Carpetrite) have layers. I wouldnt have laid it myself as it was a huge area, but my son did his own kitchen and hall with no problem at all. The professionals do it quicker. HOwever if you do it alone, remember to leave room to "breathe" around the edges or it can buckle.
Hi, to be honest I would rather get someone in than do it myself. When I was single I used to carry out all my own DIY but was able to do it at my own rate. If I got stuck or got bored, I was able to leave it for weeks unfinished if I wanted to without any problem, and get back to it when I felt like it.
I would not be able to getaway with it now, and if I got stuck or it went wrong I would get it in the neck.
It's much easier to pay someone to do it then if it goes wrong I can blame someone else. Sorry to be a wimp but it's easier in the long run.
Anyway, apart from Jackie's suggestion about the supplier laying it, does anyone know any good reliable contractors in the trade who could do it for me?
