What problems do London houses have on the outside?
Many London homes are Victorian or Edwardian, and the same issues come up again and again.
Damp and failing paint
Old solid brick walls take in water and release it again. If a gutter leaks, the pointing is open or a downpipe overflows, the wall stays wet and paint blisters or peels. Painting over a wet wall hides the problem for a season. The cause should be fixed first, then the surface can be painted with a paint that lets the wall breathe.
Stucco and render cracks
Stucco fronts, common on grand terraces in parts of west and central London, crack and lose small pieces over time. Cracks need filling and flexible repairs before painting, or water gets in behind the new coat.
Rotten timber and old sash windows
Window sills and the bottom rails of sashes are the first places to rot. Soft timber is cut out and repaired with filler or new wood before it is painted. Painting over soft wood only buys a little time.
Lead paint on older homes
Homes built before the 1960s may have old lead-based paint under later coats. Dry sanding can create harmful dust. Ask any painter how they plan to deal with it, and expect wet methods, careful cleaning and protection for the garden and the neighbours.
