Exterior scale on the foothill side
The exterior of a large foothill home is planned around sun and wind as much as square footage. Rancho Cucamonga has a hot-summer Mediterranean climate with a great many sunny days, and paint makers list a maximum surface temperature for application, so we paint each elevation when it is out of direct sun and move around the house with the shade.
Santa Ana winds are the other scheduling factor. They come down from the high desert with the lowest humidity of the year, most often in autumn, and they funnel through the passes into the inland valleys. Wind carries spray mist onto cars, windows and neighbors, so on those days we brush and roll, or move the crew inside.
Big houses also have more of the trim that takes a beating: wide eaves, tall window walls, balconies and long runs of fascia. Those are inspected and repaired before the body color goes on, so the fresh finish is not sitting over failing wood.
