The problem with grow houses
Indoor cannabis cultivation, whether illegal or outside a licensed facility, can damage a building significantly. Grow operations often involve high humidity, extensive watering, intense lighting, makeshift electrical work, ventilation holes cut through walls and roofs, and fertilizer and pesticide use. The common results:
- Moisture damage and mold growth in drywall, framing, subfloor and attics
- Electrical hazards from bypassed meters and overloaded or improvised wiring
- Structural alterations such as removed walls, holes through floors and ceilings, and sealed windows
- Chemical residues from fertilizers and pesticides
- Persistent odor
Our approach
- Safety first. A licensed electrician should evaluate and correct unsafe electrical work before remediation. We don't perform electrical repairs.
- Assessment of moisture and visible mold, affected building materials, chemical residue and odor sources.
- Moisture and mold. Assessment by appropriate professionals where significant mold growth is suspected. Some states regulate mold assessment and remediation separately.
- Removal of water-damaged drywall, insulation and flooring and any contaminated materials.
- Cleaning of structural surfaces and residue.
- Odor treatment.
- Documentation and handoff for repairs, sale or insurance.
Legal context
Cannabis laws differ by state. Legal home cultivation within limits is different from large illegal operations. Regardless of legality, the building damage needs to be handled. If law enforcement is involved, cleanup begins after release.
For buyers and lenders
Former grow houses sometimes carry disclosure requirements and lender concerns. An independent assessment and documented remediation can make a property marketable and financeable again.
Common questions
Is mold always present?
Not always, but sustained high humidity makes it common. Assessment determines the extent.
Can you restore the electrical system?
No. Electrical work requires a licensed electrician. We coordinate the sequence so repairs and remediation don't conflict.
