Open space means fine, dry dust
Moraga is ringed by grassland and regional parks, and from late spring the hills go dry. Wind carries that fine dust onto exterior-facing sills, screens and patio doors continuously, in a way that inland tract neighbourhoods surrounded by other houses simply do not experience. Sills, tracks and screens stay on the standing list here.
Big single-family homes on generous lots
Campolindo and Sanders Ranch have substantial family houses with multiple bathrooms, formal rooms used a few times a year, and a lot of built-in cabinetry. Deep-cleaning every surface every visit is not good value. We run a zone rotation instead, so the whole house cycles through properly without paying deep-clean prices each time.
