Testing & Assessment
Mold Inspection & Testing in Pasadena, CA
An assessor determines whether mold is present, identifies where it is growing, and measures how far it has spread — before any remediation quote is issued. A mold inspection locates moisture and growth that a room-level look would miss, reading wall cavities, subfloor, and the areas behind finished surfaces. The result is a scope: what is affected, what has to come out, and what is driving the moisture.
No obligation: the assessment comes before any scope
Most people reach this page after noticing something rather than after something broke: a smell that returns, a stain that spreads, a room that feels damp. An inspection answers what is actually there and where the moisture comes from, which is the information every later decision depends on. Several states, Texas among them, keep assessment and remediation as separate licensed roles specifically so the party identifying the problem is not the party selling the fix. Nothing here is medical advice — if you have health questions, those are for a clinician.

Frequently asked questions
The Arroyo channel is empty. Why is the bungalow crawlspace wet after February rain?
The water never made the channel. On a burned San Gabriel fan the rain picks up ash and cobble and stops at the first bungalow sill. A dry Arroyo is not a dry lot. The stain is fan debris holding water against a 1961 raised floor, not a roof leak, and clearing the gutter will not find the path.
Does Oak Knoll take water differently from Old Pasadena after a fire year?
It does. Oak Knoll sits on the fan. Old Pasadena sits on the basin floor. After a burn the fan gets the debris first; the floor gets the water table later. Treating both as 'foothill runoff' misses the cobble plug on one and the Raymond rise on the other.
Can a February stain here be from a fire that burned a ridge the house cannot see?
It can. The San Gabriel front sheds onto this basin whether the lot has a view or not. A cell that scours a burn scar above the Arroyo can reappear as ponded silt under Bungalow Heaven. The diagnosis follows the fan, not the skyline from the porch.
