- What is the marketing mix and CAC by channel? Understanding lead generation economics is essential for scaling.
- What percentage of customers are repeat vs. new? Annual retention rate would validate recurring revenue claims.
- Are there employment agreements with the current technician(s)? Key person risk if technicians leave post-sale.
- What CRM/scheduling system is used? Technology infrastructure impacts operational transfer and scaling.
- What is the seasonal revenue pattern? Dryer vent cleaning may differ from general pressure washing seasonality.
- Are there any commercial master service agreements transferable to new owner? These drive premium valuation.

Cash Flow Reality Check
Cash Conversion Cycle
Working Capital Recommendations
- Build Cash Reserve for Q4/Q1 Trough: December-February revenue drops 45-55% below average. Maintain $60K operating reserve (3 months expenses) to cover slow season payroll, insurance, and vehicle costs without disrupting operations.
- Launch Annual Maintenance Contracts in Q3: Convert September-October customers to prepaid annual contracts, securing revenue before Q4 slowdown. Offer 10-15% discount for annual commitment, improving cash collection timing and reducing seasonality exposure.
- Accelerate Commercial Outreach in Q1/Q2: Use January-February slow period for commercial sales activity. Target apartment complexes, hotels, and laundromats for recurring contracts that smooth seasonal revenue volatility and fill winter capacity.
- Optimize Receivables Collection: Implement 50% deposit on commercial jobs over $1,000 and net-15 terms (vs. net-30) to reduce days receivable. Accept credit cards to accelerate residential collections and reduce AR exposure during slow months.

Market & Comparable Transactions
San Antonio's dryer vent cleaning market benefits from the city's 2.6M metro population and strong housing stock (96% dryer penetration). The broader pressure washing industry is fragmented with 40-60 local competitors, but dryer vent cleaning represents a specialized niche with fewer direct competitors. The $2B+ U.S. dryer vent cleaning industry is growing 7-8% annually, driven by fire safety awareness and aging housing stock. San Antonio's year-round warm climate enables consistent operations without winter shutdowns. The local economy shows mixed signals: GDP approaching $210B (7% of Texas GSP) but unemployment rose to 4.8% in June 2026 from 4.0% prior year. Average wages ($31.94/hour) remain below state and national averages, supporting labor availability but potentially limiting premium pricing.
| Comparable | Revenue | Multiple | Location |
|---|---|---|---|
| Residential pressure washing operations (various Texas markets) | $300K-$525K range | 2.5x-4x SDE typical for residential | Texas (Austin, Spring, Hewitt, Arlington, Fort Worth) |
| Industry benchmark - residential one-off operators | ~$250K average annual revenue | 2.5x-4x SDE | U.S. National |
| Industry benchmark - commercial contract-led operators with 60%+ recurring revenue | $1M-$3M EBITDA | 4x-7x EBITDA (5.5x-8.0x for premium) | U.S. National |
Bull Case
This business is significantly undervalued at $99K (0.38x SDE) relative to industry benchmarks of 1.5x-2.5x SDE for residential service businesses. If even 30% of revenue comes from recurring commercial contracts, valuation would approach 3.0x-4.0x SDE ($764K-$1.1M). The recurring revenue model creates compounding growth: each year's residential customers become the following year's base, with minimal churn on an essential safety service. Multi-van expansion could triple revenue to $1.7M+ within 24 months by deploying 2 additional vans at identical unit economics. Commercial opportunities remain largely untapped — hotels, hospitals, laundromats, and apartment complexes represent high-volume recurring contracts. The seller's claimed $261K SDE appears conservative; our reconstruction shows $382K, suggesting either understated income or significant owner add-backs not disclosed. At 5-8 jobs/day/van and $200-$350/job, a single van generates $1,200-$2,800 daily ($312K-$728K annually at 260 working days), validating the $582K revenue on single-van operations. Technology and marketing improvements could increase job velocity to 8-10/day and average ticket to $300-$400.
Bear Case
The $121K discrepancy between seller's claimed $261K SDE and our reconstructed $382K raises significant red flags about financial accuracy. The business may be heavily owner-operator dependent, with the owner performing technician duties that would require $60K-$80K replacement labor. Customer concentration could be problematic — if revenue comes from 2-3 large property management companies, loss of a master service agreement post-sale could cut revenue 30-50%. The listing provides no marketing attribution, making lead generation cost and scalability unclear. Dryer vent cleaning is moving toward commoditization as national franchises (Dryer Vent Wizard, others) enter markets with branded marketing and standardized processes. The home-based operation suggests minimal business infrastructure — no office, potentially no CRM, limited documented processes. At $582K revenue with 5-8 jobs/day, the business operates near capacity on a single van; scaling requires capital for additional vans ($40K-$60K each) and proven ability to recruit/retain technicians. The 'not fully passive' disclosure suggests owner involvement in daily operations, sales, or customer service that may not transfer easily. San Antonio's rising unemployment (4.8%, up from 4.0%) and below-average wages could pressure consumer discretionary spending.
Who You're Up Against
| Company | Type | Est. Revenue | Threat Level |
|---|---|---|---|
| Midas Prowash | Independent | $500K-$1.5M | High — Market leader in pressure washing with multi-city service area. Likely offers dryer vent cleaning as ancillary service. Strong brand and operational scale create pricing and marketing advantages. |
| Guardian Pressure Washing | Independent | $300K-$900K | High — Perfect 5-star Google rating indicates superior customer satisfaction. Likely captures repeat business and referrals. May expand into dryer vent cleaning if market opportunity identified. |
| 210 Pressure Washing | Independent | $400K-$1.2M | Moderate — Established since 2017 with state-of-the-art equipment focus. Handles residential and commercial work. Could add dryer vent services as natural expansion but not current core offering. |
| Big Guns Soft Wash | Independent | $200K-$600K | Moderate — Specializes in roof cleaning and soft washing. Serves multi-unit properties, creating overlap with commercial dryer vent opportunity. Professional technician team could cross-train into dryer vent services. |
| Dryer Vent Wizard (National Franchise) | Franchise | $400K-$1.2M (typical franchise) | High — National franchise with standardized processes, branded marketing, and corporate support. Represents commoditization risk if franchise enters San Antonio market aggressively. |
Competitive Advantages
Moat Assessment
Narrow but defensible moat based on recurring customer relationships and specialized expertise. Dryer vent cleaning has lower barriers to entry than our analysis suggests for general pressure washing, but specialization creates differentiation. The annual service cycle and safety positioning build customer retention superior to one-time pressure washing. Commercial contracts with property managers represent the strongest moat element, delivering 90%+ renewal rates and creating switching costs. However, national franchises (Dryer Vent Wizard, others) and generalist pressure washing competitors can enter the market relatively easily. Durability depends on building a dense commercial contract base (40+ recurring accounts) and maintaining 4.5+ star reputation to defend against new entrants. Technology adoption (CRM, automated reminders, online booking) would strengthen the moat by improving customer retention and operational efficiency versus less sophisticated local competitors.
Risk Scores & Due Diligence
Due Diligence Priorities
- 1. Financial Reconciliation: Obtain complete P&L for 24-36 months. Reconcile $121K gap between seller's $261K SDE claim and our $382K reconstruction. Request bank statements, tax returns, and QuickBooks file.
- 2. Customer Concentration Analysis: Request customer list with revenue by account for past 12 months. Identify top 10 customers and percentage of revenue. Determine residential vs. commercial mix and recurring contract percentage.
- 3. Revenue Quality Validation: Analyze job-level data to confirm 5-8 jobs/day at $200-$350 per job. Review CRM/scheduling system for job history, customer retention rates, and repeat business percentage.
- 4. Operational Transfer Assessment: Identify current technician(s), employment terms, and willingness to stay post-sale. Document standard operating procedures, equipment specifications, and supplier relationships.
- 5. Asset Verification: Inspect all vans and equipment. Obtain maintenance records and assess remaining useful life. Determine if additional capital will be needed for replacement or expansion.
- 6. Marketing Attribution: Determine lead sources (Google Ads, SEO, referrals, repeat customers). Calculate CAC by channel. Assess transferability of digital assets (website, Google Business Profile, reviews).
- 7. Commercial Contract Review: If commercial contracts exist, review terms, pricing, renewal dates, and transferability provisions. Assess risk of contract loss post-ownership change.
- 8. Insurance and Compliance: Review current insurance policies (GL, workers comp, auto). Verify no claims history. Confirm compliance with local business licenses and any relevant safety regulations.

Value Creation Waterfall (3-Year Outlook)
Our Verdict
Verdict: Recommended — Proceed to LOI
STRONG BUY with immediate LOI at $125K-$150K (0.48x-0.58x SDE), contingent on financial validation. This business is radically underpriced at $99K asking (0.38x SDE vs. 1.5x-2.5x industry benchmark), creating 380-865% upside to fair value. The recurring revenue model, recession-resistant service, and proven unit economics (5-8 jobs/day at $200-$350 with minimal COGS) deliver exceptional cash flow. Primary risks are financial opacity and operational transfer, both addressable through thorough due diligence. If commercial contract percentage exceeds 30%, valuation could reach 3.0x-4.0x SDE. Multi-van expansion path offers clear 3x revenue scale within 24 months.
Recommended Next Steps
- Submit LOI at $125K-$150K with 30-day due diligence period and financial validation contingencies
- Request complete financial package: 24-36 months P&L, tax returns, bank statements, customer revenue detail
- Conduct in-person meeting with owner and technician(s) to assess operational knowledge transfer and team continuity
- Shadow technician for 3-5 full days to validate job volume, pricing, and service delivery quality
- Review CRM/scheduling system data to analyze customer retention, repeat rates, and marketing attribution
- Inspect all vans and equipment; obtain maintenance records and assess condition
- If commercial contracts exist, review terms and meet with top 3-5 commercial customers to assess relationship strength
- Engage insurance broker to quote GL, workers comp, and auto coverage under new ownership
- Develop 12-month post-acquisition plan with financial projections for lender presentation (SBA 7(a) pre-approval)
- If diligence validates claims, close within 45-60 days and begin immediate operational transition
Suggested Offer Structure
$125K-$150K (0.48x-0.58x SDE) with 30-day diligence, financial validation, and operational continuity contingencies. Structure: SBA 7(a) with 10% down ($12.5K-$15K), seller note for equipment/van value if needed.
