What each service answers
Mold Inspection
A mold inspection answers two questions: is there a moisture problem in this property, and what is it doing to the building materials around it. Holt Mold Engineering inspects homes and properties in Arcadia and nearby San Gabriel Valley communities with that focus.
Learn more about mold inspection →Situations that commonly justify a mold inspection
- A plumbing supply or drain leak, even one that was repaired quickly
- Water damage from an appliance, water heater or roof
- A musty odor with no visible source
- Discoloration on drywall, baseboard, ceiling or cabinetry
Mold Testing
Mold testing collects samples so a laboratory can provide information about indoor conditions. It is a tool used inside an inspection — not a replacement for one. We use it when it answers a question you can act on.
Learn more about mold testing →Reasons property owners ask about testing
- Musty odor without visible growth
- Concern about air quality in a specific room
- Documentation needed for a sale, lease or claim
- Verification after remediation work
Moisture Detection
Nearly every indoor mold problem begins as a moisture problem. Moisture detection locates damp building materials and the conditions keeping them damp — often before there is anything visible to see.
Learn more about moisture detection →Signs a moisture assessment is warranted
- Flooring that feels warm, soft, cupped or damp underfoot
- Water bill higher than usual with no explanation
- Baseboard separating, swelling or discoloring
- Paint bubbling, blistering or peeling in one area
Indoor Air Quality Assessment
When a property feels stuffy, smells musty, or a room seems different from the rest of the house, an indoor air quality assessment evaluates the building conditions behind it — humidity, ventilation, moisture and air movement.
Learn more about indoor air quality assessment →Reasons to request an assessment
- Musty or stale odor that comes and goes
- One room noticeably more humid or stuffy than the rest
- Windows that fog on the interior in cool weather
- Visible condensation on exterior walls or closet walls
Post-Remediation Verification
After remediation is finished and before rebuilding starts, verification provides an independent evaluation of the treated area — an assessment performed by someone who did not do the remediation work.
Learn more about post-remediation verification →When verification is worth arranging
- Remediation is complete and reconstruction is scheduled
- You want an independent assessment separate from the remediation contractor
- An insurer, lender, buyer or landlord requires documentation
- The original moisture source was uncertain
