IICRC Certified Mold Remediation — Family Owned Since 1967
Mold isn't just a cleaning job. It's a hazardous materials process — one that requires containment, the right PPE, source repair, and documentation that holds up for insurance, real-estate disclosure, and regulatory clearance. Kowalski has performed mold remediation on apartment communities, schools, offices, and single-family homes across Maricopa County for almost 60 years.
From Mold Inspection to Clearance — Five Steps
Every mold remediation project follows the same documented process so the job holds up for insurance, regulators, and resale.
- 1
Mold Inspection & Assessment
On-site mold inspection to identify visible mold growth, moisture sources, and the affected square footage. We coordinate with independent labs for clearance testing when required.
- 2
Containment
Critical-barrier containment with negative air pressure and HEPA filtration prevents cross-contamination to unaffected areas of the property.
- 3
Mold Removal & Remediation
Removal of mold-contaminated drywall, insulation, flooring, and porous materials. HEPA vacuuming and antimicrobial treatment of structural elements.
- 4
Source Repair & Drying
Identify and stop the moisture source — leak repair, structural drying — so the mold doesn't come back.
- 5
Clearance & Reconstruction
Air quality clearance, then full reconstruction of removed materials — drywall, paint, flooring, finishes — to all city codes.

What homeowners and property managers ask most when they suspect mold in a Phoenix building.
How do I know if I have mold?
Common signs: musty smell, visible spots (black, green, white, or fuzzy growth), unexplained allergy symptoms, recent water damage, or staining on drywall and ceilings. Kowalski offers IICRC-certified mold inspection — not just visible identification, but moisture mapping to find the source.
Is black mold dangerous? Can you remove it?
All mold should be taken seriously, and yes — Kowalski removes Stachybotrys (black mold) along with all other mold types. We follow IICRC S520 containment protocols: air scrubbing, sealed containment barriers, HEPA filtration, and proper PPE so spores don't spread to clean areas.
Do you do mold testing?
Kowalski coordinates with independent industrial hygienists for pre- and post-remediation testing on projects that require it (insurance claims, property transactions, sensitive occupants). Testing is kept independent of our remediation work to maintain credibility for your records.
How long does mold remediation take?
Small isolated jobs (a single bathroom or under-sink area) often complete in 1–3 days. Larger contamination events (whole-room or multi-room remediation with structural drying and rebuild) take 1–3 weeks depending on scope. Kowalski gives a realistic timeline up front based on the inspection.
Will my insurance cover mold remediation?
It depends on the source. Mold from a sudden, covered water event (burst pipe, appliance leak) is often covered. Mold from long-term humidity or ungated leaks usually isn't. Kowalski helps document the source so your insurance carrier can make the determination, and we direct-bill where coverage applies.
Can you fix the underlying water problem too?
Yes. Mold remediation without fixing the moisture source is wasted money. Kowalski handles plumbing leaks, structural drying, ventilation issues, and the full rebuild after mold remediation — one company, one project.
