For 27520 and surrounding Johnston County, the realistic range is $10-$25 per square foot. Class I (small surface spot) lands $8-$12; Class II (single-room drywall) lands $12-$18; Class III (multi-room or framing) lands $18-$25; Class IV (confirmed Stachybotrys + rebuild) lands $25-$45. Crawl-space encapsulation runs lower at $5-$11/sq ft.
Single-number quotes (usually $15/sq ft) ignore the four IICRC S520 contamination classes. A 200 sq ft Class I bathroom job priced at $15/sq ft is overpriced ($3,000 vs. $1,800 fair); the same number applied to Class IV is wildly underpriced. We quote per class so the math is honest.
Class I-III: removal only — drywall is cut out, framing exposed, area cleared for clearance testing. Reconstruction (new drywall, paint, trim) is a separate $4-$9/sq ft line item. Class IV ranges INCLUDE reconstruction allowance — we price it as a single deliverable since the two phases are sequenced.
For sudden water-damage triggers (burst pipe, appliance failure, storm leak), most NC homeowner policies cover the remediation portion. Reconstruction is usually covered too. The deductible is the homeowner's portion. We document everything for the adjuster and have a 90%+ first-pass approval rate.
Yes. The on-site inspection plus written 24-hour quote — including the exact per-sq-ft figure for your specific job in 27520 — costs nothing. Lab samples (if needed for Class IV diagnosis) carry a small lab fee disclosed before we collect.
