Richard was easy to deal with and communicated well. He did not question what we wanted (to keep the existing tiles) as another contractor had and the price was very competitive. I think he could have investigated more when coming to quote. He didn't look at the roof from inside the loft and as there was lathe and plaster with existing (likely damp insulation) above, the new insulation had to be thrown in through a couple of holes in the lathe and the new felt put over the top of the existing insulation. I was glad I got Building Control to inspect as this existing insulation was too close to the new felt and therefore he had to put Sellotex in the sloping parts of the ceiling to ensure there was a gap between the two. However, Richard did as instructed without complaint, the work was passed as meeting Building Regs and he did not unreasonably increase the price as a result. He was an extremely fast worker - maybe a bit too fast! a pleasant and amenable chap. Nice to deal with.
