When you have mold, making the correct decisions right away is critical. Whether it?s mold in your home, school, place of work or apartment there are many factors to consider. Will you be seeking property damages? Is anyone sick from mold exposure? Do you just want to test to be sure your environment is safe? Do you need Post Mold Remediation Testing to ensure a good job was done? These and other factors are questions which need to be answered before any environmental testing starts. It?s important to know what your goals are and why your testing. Different goals require different environmental tests, i.e. medical damages & property damages require different environmental tests to prove your case in court. Tests that a common or inexperienced mold inspector would not typically use or know to use.

"We worked with Craig as the sales rep to a pretty horrific sewage flood. He was clear, concise and quick to educate me in a niche field. We opted to rush the results. Craig achieved this easily as well, working with 2 departments in a space of minutes. I wouldn’t mind the flooding so much if the process were all this smooth. 😭😂"

"Edgar showed up on time & got right down to the issue. There was no testing done or a sample taken. He did give an overall scope of the work to be done. Luis sent his Certification, but no invoice was presented. It was decided that the damage done did not warrant any remediation."

Mold & toxic material tests FAQs

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.
