The SDE Method (Primary for Businesses Under $5M Revenue)

Seller Discretionary Earnings (SDE) is the foundation of mold remediation business valuation. SDE = Net Income + Interest + Taxes + Depreciation + Amortization + Owner Add-Backs. Buyers then apply a multiple to arrive at enterprise value. Mold Remediation businesses currently sell for 2.5x–4.5x SDE, with most transactions in the 3.2x range. Higher multiples go to businesses with recurring revenue, low owner dependency, and strong growth.

The EBITDA Method (For Larger or PE-Targeted Businesses)

For mold remediation businesses above $3–5M in revenue or those targeting PE buyers, EBITDA multiples are the standard. Current mold remediation EBITDA multiples range from 3.8x–7x. PE platforms pay at the higher end when acquiring add-ons that fit their existing portfolio.

Key Value Drivers

The factors that push a mold remediation business from 2.5x to 4.5x SDE: (1) Recurring revenue percentage — maintenance contract mix above 40% commands a premium, (2) Owner hours — businesses running without daily owner involvement get 0.5x–1.0x more, (3) Revenue trend — growing 10%+ per year vs. flat or declining, (4) Customer concentration — no single customer above 20% of revenue, (5) Management team depth.

What Your Financials Need to Show

To command top multiples, your mold remediation business needs 2–3 years of clean P&L statements, properly categorized owner add-backs, documented recurring revenue, and ideally a field service management system with clean job records. Buyers are willing to pay more when the story is clear and the numbers are verifiable.
