    We had to do this, Tree had to be removed and foundations were supposed to be 3m but we were allowed 2m as no roots showed on digging trench. Block and beam floor with 18" gap to allow for any heave.

    Old unfelted roof

    Hi we have a 1930 semi, the roof appears to be original and is unfelted. someone in the past has stapled plastic sheeting and bitumen felt to the underside of the rafters. I think in an attempt to stop dirt blowing through as I cant see signs of leaks. Can I replace this with a breathable...

    Insulating 1930's semi

    Thanks for the reply, I was hoping not to remove the current popcorn as I’m not 100% when it was put on and what it may contain. Hence wondering if I could go straight over top? I’d like to do the hall as well but due to the layout, it would cut into the stairs :(

    Hi, I need to build a stud wall to bring the old wall in our kitchen out to match the new wall on the extension to allow us to run kitchen cabinets along the entire run. We are going to use Ikea cabinets, these use a rail that the cabinets hang off. Will 9mm OSB be thick enough or do I need...

    damp at base of chimney

    We have a 1930's semi. I have opened the builders break on a disused chimney, but we have damp at the base. Would this most likely be from the base or from needing the chimney capped? I can get the chimney fitted with a cowl, but could it be rising damp and maybe need a chemical DPM? Thanks for...

I also had the...
