Cleaning homes in Los Altos
Los Altos homes tend to be larger, with natural stone counters, hardwood floors and lots of windows. Stone needs pH-neutral cleaners, not the acidic sprays that can etch marble and some granite, so that's what our teams use. Larger homes are priced up front by size, and many Los Altos clients start with a Deep Clean before moving to a recurring schedule.
