Foundation and basement repair in San Jose: a local guide

The work here splits into two kinds. One side is structural: stabilizing a house that has settled. Avalon Structural Inc. repairs residential foundations with horizontal crack repair, underpinning, releveling and foundation replacement, and it uses helical piles, resistive piers and drilled piers to hold a foundation in place instead of replacing it. It has worked around Aptos and across Santa Clara, Santa Cruz and Monterey counties for decades, and it is rated 4.7 from 15 reviews.

The other side is moisture. Clean CrawlSpace Inc has worked on wet, damp and moldy crawl spaces since 2004, from San Jose to San Francisco, Oakland, Santa Rosa, Napa and Sonoma. Its main service is crawl space repair and encapsulation, which pairs perimeter drainage, drainage matting, a sump pump and a dehumidifier with insulation. It also installs, replaces and services sump pumps, including backup systems. It is rated 4.9 from 27 reviews, the largest review count on the page.

EXPERT Foundation Repair San Jose sits between the two. It takes on homes with cracks, settling, uneven floors and moisture trouble, and it covers slab foundation repair, pier and beam foundation repair, crawl space repair and support, foundation inspections, leveling and long-term stabilization. It also takes on waterproofing and restoration jobs. Its rating is 5.0 from 12 reviews, which is a short history, so read the number with the count beside it.

A homeowner in San Jose can also look past the city line. The companies that work from here name San Francisco, Santa Clara, Santa Cruz, Santa Rosa and Oakland as places they go. Santa Clara, Oakland, San Francisco, Concord and Antioch each have their own page for a closer look at who works there.

For structural work, San Jose's city page on building permits says a permit is required for new construction, additions, alteration of walls or any structural change. It is a good page to read before a company starts digging or underpinning.

Because several of these companies name places far from San Jose as part of their work, a homeowner in Santa Cruz or Oakland can reach the same names a San Jose homeowner does.
