24/7 emergency property mitigation and reconstruction contractor billed via standardized insurance carrier Xactimate price lists at 70%+ mitigation gross margins.

Startup investment: $95,000–$325,000

SDE (Seller’s Discretionary Earnings) Margin
Total pre-tax cash flow available to a full-time owner-operator as a % of annual revenue: Net Profit + Owner’s Salary/Draws + Interest, Taxes, Depreciation & Amortization (EBITDA) + verified one-time owner add-backs.: 18%–30% SDE margin

Typical time to breakeven: 5–12 months

Three paths into this business: Start Independent vs. Buy Existing vs. Franchise for Water, Fire & Mold Restoration

Path 1 · Build from Scratch

Start Independent

$95,000–$325,000

Ongoing royalties: 0% ongoing franchise royalty
Time to breakeven: 5–12 months
Tradeoffs: 100% control over pricing, vendor selection, and territory with 0% ongoing royalties—preserving the full 18%–30% SDE margin target owner cash flow once ramped. Capital is concentrated upfront in Fleet of LGR Dehumidifiers, Air Movers, HEPA Air Scrubbers & Meters ($35,000–$110,000) and Outfitted Box Truck / Sprinter Van & Water Extraction Unit ($30,000–$95,000); Required compliance includes IICRC Certifications (WRT — Water Damage Restoration, ASD — Applied Structural Drying, AMRT — Mold Remediation) (5–12 months typical breakeven).

Path 2 · Acquire Cash Flow

Buy an Existing Resale

2.8x–4.4x SDE ($216,000–$2,400,000)

Ongoing royalties: 0% ongoing franchise royalty (if independent)
Timeline: 30–90 days closing (immediate Day-1 cash flow)
Tradeoffs: Immediate Day 1 revenue (typically $600,000–$2,500,000 for established operators) with trained staff, permits, and vendor accounts in place. Priced at 2.8x–4.4x SDE (Strong plumber referral networks and insurance TPA (Third-Party Administrator) program status drive value), typically financed via SBA 7(a) with 10%–20% down. Priority due diligence: Break down revenue between high-margin emergency mitigation (70%+ gross margin) vs. low-margin reconstruction (30%–35% gross margin).

Path 3 · Franchise System

Buy a Franchise

$185,336–$474,340

Ongoing royalties & fees: 5%–9% of Gross Sales + 2% national marketing (major franchise presence: SERVPRO, ServiceMaster, PuroClean)
Disclosed FDD median brand revenue: $1,024,401 (across 3 catalog brands)
Tradeoffs: Turnkey brand recognition, national vendor contracts, and playbooks across 3 FDD systems (including SERVPRO, ServiceMaster Restore, Rainbow Restoration), but ongoing royalties and ad fund fees (5%–9% of Gross Sales + 2% national marketing (major franchise presence: SERVPRO, ServiceMaster, PuroClean)) come directly out of top-line gross sales and compress net owner take-home compared with an independent water, fire & mold restoration business.

Total project / purchase price	$210,000	$1,339,200	3.6× on $372,000 SDE vs. startup CapEx

Cumulative 3-year net owner cash flow	$750,291	$563,043	Build leads by $187,248 over 3 years

SBA 7(a) underwriting & payback takeaway:

At $1,550,000 revenue and 24% SDE margin ($372,000/yr pre-debt cash flow), buying an existing water, fire & mold restoration business at 3.6× SDE ($1,339,200) generates $187,681/yr from Day 1 (2.02× DSCR), giving an immediate $123,584 Year-1 cash-flow advantage over building from scratch during a 9-month ramp-up. Once ramped in Year 2+, building from scratch ($210,000 CapEx) nets $343,097/yr (12.87× DSCR). By comparison, a 5% gross-sales franchise royalty on $1,550,000 revenue deducts $77,500/yr directly from owner cash flow.
