Ivor Davies - Image 1 "This is the second time I have used Ashmark Roofing as I was very satisfied with their work previously. Tony diagnosed the source of dampness on the gable end of my house as water running off a rendered section of wall from a poorly executed loft conversion by the previous owner. They installed a new gutter to route the water runoff and installed air bricks to vent two chimney stacks that had been capped off when the loft conversion had been done. They also repointed the wall where required. I'm pretty confident that our problem has been solved at a price that was fair."
