Frequently Asked Questions
What Types of Mold Are Most Common in Homes?
The most common indoor molds include Cladosporium, Penicillium, Aspergillus, Stachybotrys (black mold), and Alternaria. Each has different health risks and grows in different environments.
Can mold return after remediation?
Yes — mold can come back if the root cause (like moisture or poor ventilation) hasn’t been fully resolved. Even with professional cleanup, leftover humidity or hidden leaks can lead to a recurrence. That’s why post-remediation inspections with a mold detection dog like Ace are so valuable — she can confirm whether the remediation was truly effective before walls are closed or new construction begins.
If a leak was repaired but the area wasn’t dried properly, could there still be mold?
Yes — If an area stays damp for more than 24–48 hours after a leak, mold can begin growing, even if the leak was fixed. Mold can thrive behind walls, under flooring, or in insulation where moisture lingers unnoticed. Ace’s nose can detect it long before symptoms appear or visible damage is seen.
Can mold grow inside a wall without a water source?
Yes — all mold needs is moisture, not necessarily a plumbing leak. High humidity, condensation, or poor airflow can cause moisture buildup in wall cavities, creating the perfect environment for hidden mold to grow. That’s why mold can develop in places you'd least expect — and why canine detection is so effective.
Is post-remediation testing necessary if everything looks clean?
Yes — mold can still be present even when the surface looks clean. Spores and mycotoxins may linger behind walls or under floors, especially if remediation wasn't thorough. Mold sniffing dogs can confirm whether mold is still present by detecting its scent, giving you peace of mind before rebuilding or moving back in.
