Hi, we have recently had an (expensive) new kitchen fitted including fitting our tumbler dryer and its vent underneath kitchen units with wooden worktops on top. First problem - fitter did not oil underneath wooden tops so they have buckled, partly due to v bad problem with condensation we seem to be having since work done. Also, we have found the flimsy plastic flexible vent has rusted and holes have appeared, which has exacerbated condensation and caused wet floorboards. Is there a better way to fit a vent to an outside wall than a flimsy plastic vent? Is there something more robust which we could leave in place and not worry about?
