From SBA 7(a) loans to earnouts tied to contract retention, here's how buyers and sellers in the window cleaning industry close deals at the right price with the right terms.
Window cleaning businesses in the $500K–$3M revenue range are well-suited to SBA-backed acquisitions, making them accessible to first-time buyers with limited capital. Because value in this industry is tied directly to recurring commercial contracts, route density, and crew stability, deal structures must account for transition risk — the real possibility that key accounts or employees walk after the owner exits. The most common structures pair an SBA 7(a) loan covering the bulk of the purchase price with a seller note and, when customer concentration is a concern, an earnout provision tied to first-year revenue retention. Sellers who have built diversified contract bases with documented systems command cleaner, full-price structures. Those with heavy owner dependency or concentrated accounts should expect buyers to push for risk-sharing mechanisms.

The most common structure for window cleaning acquisitions under $3M. The buyer secures an SBA 7(a) loan covering 80–90% of the purchase price, injects 10% equity, and the seller carries a subordinated note for the remaining balance (typically 5–10%). The seller note is usually on standby for the first 24 months per SBA guidelines.
Pros
Cons
Best for: Deals where the window cleaning business has clean financials, at least 30% recurring contract revenue, and an owner willing to transition over 6–12 months.
Full Seller Financing
The seller finances the entire purchase price, with the buyer making monthly payments over a defined term — typically 3–7 years. This structure is less common but arises when the seller wants a steady income stream post-exit or when SBA financing is unavailable due to documentation gaps.
Pros
Cons
Best for: Retiring owner-operators selling to a trusted buyer or family member, or situations where the business has informal financials that disqualify it from SBA lending.
Earnout Structure
A portion of the purchase price — typically 10–20% — is deferred and paid out only if the business hits defined revenue or contract retention milestones in the 12–24 months following close. Earnouts are used when the buyer is concerned about losing large commercial accounts or key crew members after the ownership transition.
Pros
Cons
Best for: Window cleaning deals where the top 3–5 commercial accounts represent 35%+ of revenue, or where the owner personally manages key client relationships that must transfer to new management.
Asset Sale with Transition Agreement
The buyer purchases the business assets — routes, customer lists, equipment, vehicles, trade name, and contracts — rather than the legal entity. This is the default structure for most small window cleaning acquisitions and is paired with a seller transition and training agreement lasting 6–12 months.
Pros
Cons
Best for: The majority of window cleaning business acquisitions in the lower middle market where the buyer is an individual operator or small platform acquiring assets rather than absorbing a corporate entity.

Window cleaning businesses in the lower middle market typically sell for 2.5x–4x Seller's Discretionary Earnings (SDE). Businesses with high recurring contract revenue, diversified customer bases, and documented systems command the upper end of that range. Owner-operated businesses with heavy customer concentration, aging equipment, or informal records fall closer to 2.5x. For a business generating $300,000 in SDE, expect a realistic asking price in the $750,000–$1,200,000 range.
Yes. Window cleaning businesses are SBA-eligible, and the SBA 7(a) loan program is the most common financing vehicle for acquisitions in this industry. You'll need to inject at least 10% equity, and the business must demonstrate sufficient cash flow to service the debt — typically a 1.25x debt service coverage ratio or better. The business will also need 2–3 years of clean tax returns. If the seller has unreported cash revenue or co-mingled personal expenses, the deal may not qualify for SBA financing without significant recharacterization.
Earnouts are used when a significant portion of revenue comes from a small number of commercial accounts or when the owner personally manages key client relationships. If the top 3 accounts represent 40% of revenue and those relationships are owner-dependent, a buyer is right to be cautious about paying full price upfront. An earnout tied to first-year revenue retention — typically 10–20% of the purchase price — protects the buyer while giving the seller a clear path to full value if the transition goes smoothly.
In an asset sale, you purchase the routes, customer contracts, equipment, vehicles, and trade name — but not the legal entity itself. This protects you from inheriting prior liabilities like old insurance claims, employment disputes, or unpaid taxes. Most small window cleaning acquisitions are structured as asset sales. In a stock or entity sale, you buy the company itself, which is simpler administratively but transfers all historical liabilities. Entity sales are more common in larger deals or when contract assignment is administratively complex.
For most window cleaning acquisitions, a 6–12 month seller transition is standard. The first 90 days should involve the seller actively working alongside the buyer — introducing them to crew leads, key commercial account contacts, and walking through daily scheduling and quoting processes. Months 4–12 typically involve lighter-touch availability: answering operational questions, supporting contract renewal conversations, and being available if a major client threatens to leave. For businesses with high-rise or specialized work, a longer hands-on period may be warranted to transfer safety certifications and client trust.
The most common deal-killers are: undisclosed cash revenue that can't be reconciled to bank statements (which tanks SBA eligibility), customer concentration where 2–3 accounts represent 40%+ of revenue without assignable contracts, equipment and vehicle fleets requiring immediate capital replacement, and crew misclassification where employees are treated as 1099 contractors exposing the buyer to back taxes and penalties. Buyers should also watch for OSHA safety violations or pending insurance claims related to falls or property damage — both carry forward liability that can surface post-close.
