I started Santa Clarita Mold Inspection after my family went through a costly remediation that proved to be unnecessary. That is why our company’s focus is solely on mold testing and air quality — never remediation. My goal is to help as many people as possible get honest answers about their air quality. We are a family owned business and we enjoy what we do. Every home I step into, I treat like my own, every time.

"Extremely courteous and professional. If you have any doubt about mold in your home, contact Santa Clarita Mold Inspection to give you an honest and detailed report. "

An established Mold Testing / Mold Inspection business since 2000 that offers not only a complete analysis of your home or business but can also provide the best answers to solve questions about any health or medical issues that maybe caused by mold. We offer competitive pricing and try to treat each job as if it were our home and our family. We pride ourselves in excellent thorough service to not only get the best results but to also get the answers you need. We service the state of California from San Diego to Sacramento. We DO NOT DO remediation, that way there is no vested interest on jobs results. We also send out our test samples to EM Labs for an independent analysis so we have no say how they come out. Many mold remediation companies offer cheap or free testing, but they have a vested interest in finding mold to get the mold remediation job that can cost thousands. We offer Mold, Formaldehyde, Benzene, Methane, VOC testing and more.

"Mold is a reason for death. You need the right company. We found mold in the house that wasn't found during inspection. When we called them and told them about the situation, the owner said "It is not my job, I only tell you that there is mold. I don't tell you the location!". Then WHY do you list all the locations in your report???? AND miss to list another one??"

FAQs for mold & toxic material test projects in Valencia, CA

Some companies offer a no‑cost phone or video consultation that screens for red flags. If the discussion points to a real issue, the pro will recommend a paid on‑site inspection. The complimentary call clarifies whether you need full testing, but it isn’t a substitute for samples, lab work, or a written report. Always confirm what the free service covers before you schedule.

A standard inspection, which includes basic air and surface samples, takes an average of two hours. If the pro needs to probe hidden spaces, such as wall cavities or ductwork, plan on up to six hours. Extra time allows the inspector to reach tight areas, collect additional samples, and document findings. Lab analysis is a separate process and often adds several business days to the overall timeframe before you receive the full report.

Mold thrives where moisture lingers and air flow is poor. Common hotspots include bathroom walls, kitchen backsplashes, window sills, HVAC vents, fireplaces, crawl spaces, and enclosed attics. Check these areas regularly—especially after leaks or high‑humidity weather—to catch growth early and avoid costly repairs.

Unchecked mold can knock 20% to 37% off a home’s market value because buyers worry about hidden damage and health risks. Even after remediation, visible staining or a history of major moisture issues can still lower offers and prolong the time on the market. Addressing mold quickly protects both your property’s structural integrity and its resale appeal.
