This isn't actually a DIY question, as I'm not planning to do the work myself. Hope that's OK!
I want a loft hatch with a pull-down ladder. Two tradespeople I've asked for quotes have said that because the house is a Victorian/Edwardian terrace with lath and plaster ceilings, when the hole is cut in the landing ceiling, the whole landing ceiling is likely to come down, and then the house would be filled with very fine filthy dust. (Good job I [i]didn't [/i]try to do it myself!)
Is there any way to prevent this? I'm wondering if the lath structure could somehow be secured around the hatch area bedore the hatch is cut out. And could the cut be made by drilling holes first, making a dotted line, rather than jigsawing straight into the fragile laths?
