Sun Valley homes built before 1980 often feature stucco exteriors and crawlspaces that trap moisture after winter rains near Hansen Dam Recreation Area. Our inspection begins with thermal imaging and moisture metering on every accessible surface, including attics where dry summers can mask slow leaks from roof penetrations. We document visible growth and hidden colonies in Shadow Hills properties where hillside grading directs runoff toward foundations.
In La Tuna Canyon and Pacoima-adjacent blocks, older single-wall construction allows air from the hot, dry summers to pull humidity through unsealed vents, feeding mold on drywall paper. We test air samples in occupied rooms and compare them to outdoor baselines from Sun Valley Park to isolate indoor amplification. Every finding includes a written map showing exact locations so homeowners can verify the scope before any remediation begins.
Los Angeles County code requires proper containment and negative air during any disturbance, and our inspection reports note whether current conditions already violate those standards. We flag plumbing penetrations behind kitchen walls in Glendale-border homes and check HVAC ducts that commonly route through unconditioned attics here. The final report lists recommended next steps without pressure to sign for remediation on the spot.
Technician insight
In Sun Valley the thing that catches most people out with home mold inspection is 1950s-1970s stucco homes in La Tuna Canyon where the dry summer heat pulls moisture from the soil up through slab edges that never got proper under-slab vapor barriers.
Hidden moisture behind bathroom wall
A Sun Valley homeowner noticed musty odor after a pipe leak. We found elevated moisture in the shared wall with the laundry room that had wicked into the drywall paper. Thermal imaging confirmed the plume extended into the adjacent bedroom closet. We isolated the leak source, took air samples, and delivered a report that let the owner schedule targeted removal without opening unrelated areas.
How it works
- 1
Initial Walkthrough
We arrive at the Sun Valley address and review visible signs of water intrusion around windows, bathrooms, and exterior stucco.
- 2
Moisture and Thermal Mapping
Meters and infrared cameras scan walls, ceilings, and floors to locate hidden damp areas common in older county housing.
- 3
Air and Surface Sampling
Samples are collected from multiple rooms and sent to an independent lab for species identification.
- 4
Report Delivery
A detailed written report with photos, lab results, and prioritized recommendations is emailed within 48 hours.
Pricing
Inspection pricing depends on square footage, number of samples, and property age; we provide upfront quotes after the walkthrough.
