$/sqft rate

How the math works

100 sqft bathroom mold: ~$1,500 + $600 testing + $800 containment = $2,900. Whole-house with HVAC: $25K-$40K.

Find the water source first. Remediating without fixing the leak means mold returns in 3-6 months. Insurance sometimes covers (flood/storm); almost never covers (gradual plumbing leaks).

How to Use

  1. Enter affected sqft and area type (bathroom, basement, attic, etc.).
  2. See mold remediation cost.

Frequently Asked Questions

Testing required?

Before and after. Air samples and surface swabs confirm mold type and levels. $300-$600. Don't start remediation without knowing what you're dealing with.

Water source fix included?

Usually separate. Mold remediation removes mold; you still need to fix the water source (leaking pipe, roof, flooded basement) to prevent return. Budget $500-$5,000 separately.

Rates by area?

$15-$30/sqft typical. $10 for surface-only light mold; $40+ for attic/crawl space with HVAC contamination. Whole-house or toxic species (Stachybotrys): $25K-$75K+.
