From SBA 7(a) financing to equity rollovers, here is how buyers and sellers in the CCTV inspection and trenchless repair industry structure acquisitions in the $1M–$5M revenue range.
Sewer inspection and repair businesses — particularly those with CCTV inspection fleets, CIPP lining capabilities, and municipal master service agreements — transact at EBITDA multiples of 3.5x to 6x depending on revenue quality, equipment condition, and contract transferability. The equipment-heavy nature of these businesses, combined with the licensing requirements for NASSCO-certified technicians and the complexity of municipal contract assignments, makes deal structure more nuanced than in lighter-asset service businesses. Most transactions in this space fall into one of three structures: SBA 7(a) financed deals with a seller note bridging the equity gap, all-cash strategic acquisitions with a consulting transition agreement, or equity rollover structures used by PE-backed roll-up platforms. The right structure depends on whether the buyer is an owner-operator using SBA financing, a strategic acquirer with existing infrastructure cash, or a platform seeking to retain the seller as a minority partner. Understanding the tradeoffs of each approach — and how factors like municipal contract transferability, deferred equipment capex, and owner dependency affect deal terms — is essential for both buyers and sellers entering a transaction.

The buyer uses an SBA 7(a) loan to finance the majority of the purchase price, contributing 10–15% equity down and negotiating a seller note for the remaining gap between the loan amount and the total deal price. The seller note is typically subordinated to the SBA loan and carries a 6–8% interest rate with a 3–5 year repayment term. This is the most common structure for first-time buyers or owner-operators acquiring a sewer inspection company without institutional capital backing.
Pros
Cons
Best for: First-time buyers or owner-operators with plumbing or excavation backgrounds acquiring a profitable sewer inspection and repair company with clean financials and a diversified contract base
All-Cash Acquisition with Transition Consulting Agreement
A strategic acquirer — typically a regional plumbing company, drain cleaning platform, or PE-backed home services roll-up — pays cash at closing and retains the seller under a 90–180 day consulting agreement to ensure contract continuity, introduce the buyer to municipal clients, and transfer operational knowledge. The seller receives a clean exit with no deferred consideration, and the buyer gets full ownership and operational control from day one.
Pros
Cons
Best for: Strategic acquirers or PE-backed platforms with existing capital, operational infrastructure, and the ability to absorb contract risk, acquiring a well-documented business with transferable municipal MSAs
Equity Rollover with Reduced Upfront Payment
The seller retains a 10–20% equity stake in the acquiring platform or newly formed holding company in exchange for a lower upfront cash payment. This structure is commonly used by PE-backed roll-up platforms building out a regional sewer inspection and trenchless repair portfolio. The seller participates in future value creation when the platform is recapitalized or sold, effectively trading immediate liquidity for potential upside.
Pros
Cons
Best for: Experienced owner-operators who believe in the long-term value of the roll-up thesis and want to participate in platform upside rather than taking a one-time exit at a lower standalone multiple

Most sewer inspection and repair businesses in the $1M–$5M revenue range sell for 3.5x to 6.0x trailing twelve-month EBITDA. Businesses at the high end of the range typically have long-term municipal master service agreements with automatic renewal provisions, a NASSCO-certified workforce that is not dependent on the owner, modern and well-maintained CCTV and CIPP lining equipment, and diversified revenue across inspection, lining, spot repair, and emergency services. Businesses closer to 3.5x often have aging equipment, owner dependency, or revenue concentrated in a single municipal or commercial client.
Yes. Sewer inspection and repair businesses are SBA-eligible, and SBA 7(a) loans are commonly used by buyers in this space. The SBA will lend against the enterprise value of the business, and lenders will require a business appraisal, an equipment appraisal for the CCTV fleet and jetting units, three years of tax returns, and verification of any municipal contracts. Buyers typically contribute 10–15% equity down, with a seller note of 15–25% bridging the gap between the loan amount and total deal price. SBA lenders experienced in trades and utility services are best positioned to underwrite these transactions efficiently.
It depends on the contract language and the municipality's procurement rules. Some municipal master service agreements contain assignment clauses that permit transfer to a new owner with written consent from the municipality, while others require the contract to be re-bid when ownership changes. Buyers should conduct a thorough review of every municipal contract during due diligence, and sellers should proactively contact municipal clients early in the process to understand assignment requirements. Transactions where contract transferability is uncertain often include earnout provisions tied to contract retention to protect the buyer's invested capital.
Owner dependency is one of the most significant value killers in this industry. If the founder is the sole licensed operator, primary estimator, or only person managing municipal relationships, buyers will discount the purchase price or structure a larger portion of consideration as deferred through earnouts and seller notes to account for transition risk. Sellers preparing for exit should invest 12–24 months before going to market in cross-training a lead technician or operations manager to handle estimating, NASSCO certification requirements, and key client communication so the business can operate independently of the owner.
Equipment — including CCTV inspection cameras, jetting trucks, pipe-lining units, and robotic cutters — is typically included in the total enterprise value of the business rather than purchased separately unless the deal is structured as an asset sale with a separate equipment schedule. Buyers should obtain an independent equipment appraisal to verify fair market value and identify any deferred maintenance or near-term replacement needs. Sellers should present clean maintenance logs and service records for all units to support full equipment value. In SBA-financed deals, equipment appraisal is a lender requirement and directly affects the loan amount the buyer can access.
An earnout is a portion of the purchase price that is paid to the seller after closing, contingent on the business meeting specific performance targets — most commonly municipal contract retention, revenue thresholds, or EBITDA goals measured 12–24 months post-close. Earnouts are most commonly used in sewer inspection deals when there is uncertainty about whether key municipal contracts will successfully transfer to the new owner, when the seller is the primary relationship holder and there is transition risk, or when the buyer and seller cannot agree on a headline valuation and the earnout bridges the gap by tying a portion of payment to future performance.
