What Makes Walnut Creek and Concord Different
Walnut Creek, Concord and the towns around them sit in the valley below Mount Diablo, east of the Berkeley Hills. Summers are hot and dry, and nearly all the rain falls between November and March. When a strong atmospheric river stalls over the East Bay, creeks that are dry in summer fill fast, and hillside yards shed water toward homes built below them.
Much of the housing went up in the 1950s through the 1970s, and many of those ranch homes sit over a crawlspace or on a slab. The heavy clay soil here swells when it gets wet and shrinks in summer, which can crack foundations and the pipes that run through them. A crawlspace that holds standing water after a storm will feed mold and rot under the floor, so have it drained and dried rather than waiting for summer.
Homes from before 1978 may have lead paint, and popcorn ceilings, old flooring and duct wrap may contain asbestos. Test before you cut out wet drywall or pull up old tile. The area also sits near active faults, and a shaken water heater that tips can flood a garage. Strap the water heater and know where your main shutoff is.

Checking a License in Walnut Creek and Concord
California requires a license from the Contractors State License Board for most home repair work. Look up any company’s license number on the board’s website before you sign, and check that it is active and bonded and that workers compensation insurance is on file. California has no separate state mold license, so ask whether the technicians hold industry certification in water damage and mold remediation. Asbestos work needs its own certification, so ask about it by name when a job may disturb older materials.
