Protect Your Properties. Protect Yourself.
A tenant mold complaint starts a legal clock. Without documented proof of proactive maintenance, you have no defense. Our IAQ programs give you both — clean air and a paper trail.
What Happens When a Tenant Reports Mold
In New Hampshire, Maine, and Massachusetts, tenants have legal protections around indoor air quality and mold. Here's what's at stake.
New Hampshire
RSA 48-A:14
Tenants who report mold or air quality issues in writing trigger a 14-day response clock. If you can't show documented maintenance, you're exposed to lease termination, court-ordered repairs, or compensation claims.
Maine
14 MRSA §6021 (effective Jan 2026)
Mold was explicitly added to the implied warranty of habitability. Landlords are now legally required to address mold conditions — and tenants have new grounds for lease termination or legal action if they don't.
Massachusetts
Implied Warranty of Habitability
Tenants can withhold rent, seek court orders, or pursue damages for conditions that affect health and safety — including persistent mold and poor air quality in residential units.
The common thread?
In every state, the landlord who can show documented, proactive air quality maintenance is in a stronger legal position than the one who can't. The question isn't whether you should maintain your properties — it's whether you can prove it.

More Than Clean Air — A Legal Paper Trail
Every subscription visit produces documented evidence of proactive property maintenance.
Documented Proof of Maintenance
Every visit produces a timestamped air quality report with before/after readings. If a tenant files a complaint, you have evidence that you were proactively maintaining the property.
Early Warning Before Costly Repairs
Monthly moisture checks and air quality monitoring catch rising humidity, hidden leaks, and early-stage contamination — before they become a $2,300–$10,000 remediation project.
Tenant Retention & Satisfaction
Properties with documented air quality programs have fewer complaints, fewer turnover costs, and tenants who stay longer. Clean air is a selling point, not just a maintenance item.
Insurance & Liability Protection
Proactive IAQ documentation strengthens your position with insurers and reduces exposure if a claim is filed. Some carriers are beginning to factor maintenance history into coverage decisions.
Compliance-Ready Reporting
Reports are formatted for property management files, insurance claims, and legal documentation. Share them with tenants, owners, or attorneys as needed.
Priority Emergency Response
Subscription clients get priority scheduling for water damage events, mold scares, or tenant-reported air quality issues. No waiting in the queue when time matters.
