{Two years of musty smell in our {Diamond Bar} basement we kept blaming on old construction. Finally tested it — significant mold behind the drywall.

Two years of guessing solved in one week.|Called Steve Grant Plumbing - Fast Save Test for a {Diamond Bar} crawl space inspection after heavy rain flooding. They found early-stage mold before it spread, treated it, encapsulated the crawl space, and the follow-up test was clean. Catching it early saved me from a much bigger remediation cost. Should have scheduled an inspection sooner.}
