Mold Removal/San Marino, CA
A house this careful
hides it well.
Period plaster gives almost no warning, and a deep irrigated lot keeps the ground under it damp. The office is on Huntington Drive, so the visit is usually the same or next day.

Mold Zero is based at 2060 Huntington Dr. San Marino visits are as close to same day as this company gets, and the inspection costs nothing.
Why San Marino houses grow mold
San Marino’s housing stock is mostly period revival, built in the 1920s and 1930s to a standard that has kept it standing beautifully for a century. Lath and plaster over wood frame, raised foundations, deep lots, generous unconditioned attics. It is exactly the kind of construction that gives no early warning, because plaster does not bubble and stain the way modern drywall does.
The water usually comes from the landscaping. Large irrigated lots, mature planting close to the foundation, and decades of grade changes that quietly turned the fall toward the house rather than away from it. Under a raised floor with bare soil and no vapor barrier, that irrigation becomes a permanent source of humidity against the joists.
The second source is the mechanical work added over the years. Central air, updated bathrooms and remodelled kitchens all arrived long after the house did, and each one put a duct, a drain or a vent somewhere the original builder never planned for. An HVAC condensate line terminating under the floor is a common find here, and it runs all summer without anyone noticing.
What an inspection checks first in San Marino
First stops on a San Marino property
- The crawlspace: bare soil, vapor barrier, and where the irrigation is landing
- Grade and hardscape against the foundation, because decades of landscaping change the fall
- HVAC condensate lines, particularly any terminating under the house rather than outside it
- Attic sheathing above bathrooms that were remodelled after the house was built
- Original plaster walls on the irrigated side of the property, metered rather than looked at
Why demolition is the wrong first move here
Original plaster, period tile and hardwood are the reason these houses are worth what they are worth, and none of it is replaceable in kind.
Opening a wall treats those materials as obstacles between a crew and a cavity. Reaching that cavity with the fog means the argument about matching a 1929 plaster finish usually never has to happen.
Neighborhoods this comes up in most: Huntington Drive, Lacy Park, Mission Street. The method does not change by address; what the inspector expects to find does.
The best-kept houses hide it longest.
There is a pattern in this city: the properties that have been maintained most carefully are the ones where growth runs longest before anybody finds it, because nothing on the surface ever looks neglected. The crawlspace and the attic are where the evidence lives, and they are the two places a well-kept house gives nobody a reason to open.
Mold removal questions San Marino owners ask
Usually same or next day. The office is at 2060 Huntington Dr, so this is the shortest drive on the schedule, and San Marino requests tend to get the first available slot rather than the first available slot in a route.
No. The fog does not wet surfaces the way a spray does and it does not alter finishes, which is the reason it suits this housing stock. Any section that genuinely has to be opened, because the material is saturated rather than contaminated, is identified and flagged before work starts rather than discovered mid-job.
Dry to the touch is not dry. Soil releases moisture continuously into the space above it, and with a deep irrigated lot that release does not stop in summer. A barrier between the soil and the floor structure is the cheapest correction available on most properties in this city.
If treatment happens, post-treatment air samples go to an independent laboratory and that report goes to the property owner. A report from a lab that did not perform the work carries weight with a lender or a buyer that a contractor’s own certificate does not.
