Bungalows, stumps and what a century does to a floor
A Californian bungalow on stumps has almost always moved. Restumping, settling and a hundred years of seasonal change leave a subfloor that is rarely flat, and that is the single thing most likely to turn a straightforward flooring job into a preparation job.
Check it with a straightedge before choosing a product. Lay it in any direction and look for a gap underneath. If a whole room fails, the preparation is the bigger half of the work and worth pricing before you commit to a colour.
The compensation is that these houses have generous rooms and good light, which suits a wide plank. A more rigid 9mm board bridges minor undulation better than 7mm over this kind of subfloor.
