Mold Remediation in Van Nuys, CA | Inspection, Removal, Prevention
Warm Valley weather, older plumbing, and occasional roof leaks make Van Nuys homes prime candidates for mold. Small leaks behind walls or under floors quickly escalate into air-quality problems if not handled correctly. Onsite Pro Restoration provides certified mold inspections, safe removal, and prevention strategies tailored to Van Nuys properties.

Signs You May Need Mold Remediation
Musty Odors, Stains, and Allergy Flare-Ups
Persistent musty smells, discoloration on drywall or ceilings, and worsening allergies or coughing are early flags. These issues often appear after prior water damage that never fully dried.
High Humidity or Previous Leaks
Attics, bathrooms, and laundry rooms commonly show hidden growth if ventilation is weak. Older homes near Burbank Blvd and Victory Blvd often have legacy moisture issues in wall cavities and crawl spaces.
Tenant Complaints in Multi-Unit Buildings
In apartments along Vanowen or Sepulveda, a leak in one unit can migrate to neighbors. We coordinate access and documentation across units and management.
Our Certified Mold Remediation Process (IICRC S520)
Inspection, Moisture Mapping, and Air/OEM Sampling When Needed
We locate the moisture source, map affected materials with meters and thermal imaging, and advise on sampling where it changes scope or provides clarity for health or insurance decisions.
Containment and Negative Pressure
We build polyethylene containments with zipper access, then run HEPA-filtered negative air to prevent cross-contamination. Supply/return vents are sealed. Hallways and entries get floor protection.
Source Removal and Detail Cleaning
We remove visibly impacted porous materials that cannot be restored (e.g., mold-colonized drywall, carpet pad). Framing is cleaned with HEPA vacuuming, mechanical agitation, and targeted antimicrobial application. We avoid unnecessary “spray and pray.” Source removal drives results.
Drying and Humidity Control
Dehumidifiers and directed air flow bring materials back to target moisture levels. We monitor and log readings daily. Drying is the difference between a clean job and a repeat problem.
Post-Remediation Verification (PRV)
Upon request or when required, a third-party assessor performs PRV. Passing criteria often includes visual clearance, odor-free area, and acceptable air samples for the project context.
Documentation for Owners and Insurers
You receive photos, moisture logs, equipment logs, and a step-by-step record of containment and cleaning. This reduces friction with adjusters and protects you during future disclosures or tenant questions.
Common Mold Scenarios We See in Van Nuys
Bathroom and Laundry Venting Gaps
Improper or missing vent terminations push humid air into attics. We coordinate simple fixes with your contractor or handyman to prevent recurrence.
Attic Leaks and Roof Penetrations
Flashing failures and clogged gutters let water soak insulation and sheathing. We remediate affected zones and recommend roof repairs to stop the source.
Crawl Space Humidity and Soil Vapor
Poor grading, broken irrigation, or plumbing drips load crawl spaces with moisture. We remove contaminated soil where appropriate, disinfect contact surfaces, and add drying to bring humidity under control.
Health and Safety Considerations
We run HEPA negative air in containment to maintain pressure differentials.
We follow PPE protocols and controlled waste handling.
We never fog in lieu of source removal. Fogging is for adjunct disinfection, not a substitute for demolition where growth is established.

Mold Prevention: Keep It From Coming Back
Fix leaks fast. Replace aging supply lines and valves.
Improve bathroom and laundry ventilation. Vent to exterior, not the attic.
Keep indoor RH ~40–50%. Use dehumidifiers in problem areas.
Maintain roof, gutters, and grading so water flows away from the foundation.
After any water event, dry to target moisture levels before closing walls.
Cost Factors in Mold Remediation
Area size and accessibility: Small bath wall vs. multi-room attic.
Materials affected: Drywall only vs. drywall + insulation + framing.
Containment complexity: Single room vs. multiple chambers with decon.
PRV requirements: Third-party clearance adds testing costs.
Cause repair: Roof, plumbing, or venting fixes are separate trades.
Timeline
Inspection and scope: Same day.
Containment + removal + initial cleaning: 1–2 days for small jobs, longer for multi-room.
Drying and verification: Typically 2–4 additional days depending on materials and humidity.
Rebuild: After PRV passes and moisture targets are met.
