The 1930s house is a design icon and the first truly modern British home, with over three million built. But many are now in need of 'essential repairs'. Problems like cavity wall tie failure, corroded metal windows, unstable bays, collapsing drains and subsidence are well-known, but how can you tell if your house has major defects or is just typical for its age? Forget 'makeovers': this easy-to-use manual shows where to look for danger signs, what's 'normal' and what isn't, and how to fix common defects. You'll also be able to talk the same language as builders and property professionals. This is the first book to cover logically all defects common to 1930s houses.
