What causes condensation on windows, walls and in the loft, how to stop it with heat, ventilation and less moisture, the Part F fan rules, and how to tell it from a leak or damp.
The signs of woodworm, how to tell old holes from an active infestation, what causes it, DIY against specialist treatment, bats in the loft, and buying a house with woodworm.
What black mould is, how dangerous it is and for whom, how to remove a small patch safely, why bleach falls short, how to stop it returning and who fixes it in a rented home.
No. Most diagnosed rising damp turns out to be condensation, a leaking gutter or a bridged damp course, none of which need injection. Pay for an independent survey from someone who is not quoting for the remedial work.
