Why Mill Valley is hard on carpet & rug
What wears out carpet in Mill Valley is not dirt, it is grit. Between the Dipsea steps, the Old Mill and Cascade trailheads, and a dog population that uses all of them, the soil that comes through a front door here is sharp and mineral. It sits at the base of the pile and cuts the fibers every time somebody walks over it. That is why the entry, the hallway, and the top two stairs go before the rest of the house does.
The timing matters more than most people expect. Cleaning lifts that grit out and restores the color, but it cannot put back a fiber that has already been abraded — once a traffic lane looks matted rather than dirty, it is texture loss, and it is permanent. Getting the grit out on a schedule is the whole game, and we will tell you honestly which lanes are still worth treating and which are past it.
Mill Valley houses also run heavy on wool: wool broadloom in the older stock around Old Mill and Blithedale Canyon, and wool area rugs almost everywhere. Wool is cleaned on location with pH and moisture matched to the fiber, and the rug never has to leave the house. The exceptions we will flag rather than risk are sisal, jute, and seagrass, which are common in Marin interiors and are not suited to hot water extraction at all.
