Finance Your Drain Cleaning & Hydro Jetting Acquisition with an SBA Loan
SBA 7(a) loans cover up to 90% of the purchase price for qualified drain cleaning and hydro jetting businesses — making it possible to acquire a recession-resistant, essential services company with as little as 10% down.

Drain cleaning and hydro jetting businesses are strong candidates for SBA 7(a) acquisition financing. These businesses generate non-discretionary, recurring revenue from residential, commercial, and municipal customers — exactly the cash flow profile SBA lenders favor. A typical acquisition in this space involves purchasing tangible assets including hydro jetting trucks, CCTV camera inspection systems, and vacuum excavators alongside goodwill tied to local brand reputation and commercial maintenance contracts. SBA 7(a) loans allow buyers to finance both the hard assets and the intangible goodwill in a single loan structure, which is a critical advantage over conventional business lending. With average EBITDA multiples ranging from 2.5x to 4.5x SDE and deal sizes frequently falling in the $1M–$5M range, this industry is well within SBA loan limits. Lenders with home services experience understand how to underwrite equipment-heavy service businesses, and many are comfortable with the asset base and cash flow predictability that established drain cleaning operations provide.
Down payment: Most SBA 7(a) acquisitions in the drain cleaning and hydro jetting space require a buyer equity injection of 10%–15% of the total purchase price. On a $2M acquisition, that translates to $200,000–$300,000 in buyer equity. Sellers frequently contribute a subordinated seller note of 5%–10% of the purchase price, which can be counted toward the equity requirement when the seller note is on full standby — meaning no payments to the seller during the SBA loan term. This structure allows a buyer to close a $2M drain cleaning deal with as little as $100,000–$150,000 in personal cash when a seller note is layered in correctly. Buyers should also budget for closing costs of 2%–4% of the loan amount, including SBA guarantee fees, lender fees, legal costs, and a third-party equipment appraisal — which lenders will require given the value of hydro jetting trucks and CCTV systems in the asset base.
SBA Loan Options
SBA 7(a) Standard Loan
10-year term for goodwill and working capital; up to 25 years if real estate is included; fixed or variable rates typically ranging from 10.5%–13% depending on prime rate at closing
$5,000,000
Best for: Full business acquisitions including hydro jetting trucks, CCTV camera systems, goodwill, and working capital in a single loan — the most common structure for drain cleaning deals in the $1M–$4M range
SBA 7(a) Small Loan
Same term structure as standard 7(a) with streamlined underwriting and faster approval timelines, typically 30–45 days to close
$500,000
Best for: Smaller drain cleaning acquisitions or add-on purchases such as a route acquisition, a single-truck operation, or an equipment-heavy tuck-in deal where the purchase price falls below $500K
SBA 504 Loan
10- or 20-year fixed rate on the CDC tranche; conventional lender covers 50%, CDC covers 40%, buyer injects 10%
$5,500,000 combined (CDC portion up to $5M)
Best for: Acquisitions where the drain cleaning company owns its facility or real property, allowing the buyer to finance both the business and the real estate in a single structured deal with a below-market fixed rate on the long-term tranche
Eligibility Requirements
- The business being acquired must be a for-profit U.S.-based operation with annual revenue typically under $8M for the drain and sewer cleaning services sector, keeping it within SBA small business size standards
- The buyer must inject a minimum of 10% equity at closing — for a $2M drain cleaning acquisition, that means at least $200,000 in verified personal or business equity
- The target business must demonstrate sufficient cash flow to service the proposed debt, typically requiring a debt service coverage ratio (DSCR) of 1.25x or higher based on trailing twelve-month SDE or EBITDA
- The buyer must have relevant industry experience or management competency — lenders favor buyers with a plumbing or trades background, or prior business ownership experience in home services
- All equipment included in the acquisition — hydro jetting units, CCTV systems, and commercial vehicles — must be clearly inventoried and appraised, as tangible collateral strengthens the loan package
- The seller must not retain any ownership stake post-closing unless a seller note is structured as fully subordinated to the SBA loan with a standby agreement in place during the loan term
Step-by-Step Process
Define Your Acquisition Criteria and Get Pre-Qualified
Before approaching sellers or brokers, work with an SBA lender experienced in home services acquisitions to get a pre-qualification letter. Provide personal financial statements, tax returns for the past 3 years, a resume demonstrating your trades or business management background, and a target deal size. Lenders will assess your liquidity for the down payment, your credit profile, and your ability to manage a drain cleaning operation. Pre-qualification strengthens your credibility with sellers and accelerates the LOI process.
Identify a Target Business and Sign a Letter of Intent
Source drain cleaning and hydro jetting businesses through business brokers specializing in home services, direct outreach to owner-operators, or M&A platforms. Evaluate targets against core criteria: minimum $300K SDE, diversified customer base with no single client over 20% of revenue, well-maintained hydro jetting fleet with documented maintenance records, and at least 3 years of operating history. Once you identify the right target, negotiate and execute a Letter of Intent (LOI) outlining purchase price, deal structure, seller note terms, and an exclusivity period for due diligence.
Conduct Due Diligence on Equipment, Financials, and Customer Contracts
This is the most critical phase for drain cleaning acquisitions. Hire a third-party mechanic or equipment specialist to physically inspect all hydro jetting trucks, vacuum excavators, and CCTV camera systems — assessing condition, hours of use, remaining useful life, and any deferred maintenance. Simultaneously, review 3 years of tax returns and P&L statements, reconcile owner add-backs, analyze the commercial maintenance contract portfolio for renewal terms and customer concentration, verify all technician licenses and certifications, and review insurance history for sewer line damage claims or liability incidents.
Submit a Complete SBA Loan Package to Your Lender
Work with your SBA lender to compile the full loan package. Required documents typically include: 3 years of business tax returns and interim financials, a business valuation or broker opinion of value, a complete equipment appraisal, a copy of the signed asset purchase agreement, your personal financial statements and tax returns, a business plan with financial projections for years 1–3, and documentation of all commercial maintenance contracts being transferred. Lenders will also require a copy of any seller note agreement confirming it is subordinated to the SBA loan.
Receive SBA Approval and Move to Closing
Once the lender submits the loan package to the SBA (or approves under delegated authority), expect a conditional approval with a list of closing conditions. These commonly include a final equipment appraisal, confirmation of insurance coverage including commercial auto and general liability, a bill of sale and asset purchase agreement executed by both parties, assignment of commercial maintenance contracts, and evidence of your equity injection. Work with a closing attorney experienced in SBA transactions to navigate lien searches, UCC filings, and the final settlement statement.
Common Mistakes
- ✗Underestimating the importance of a third-party equipment appraisal — SBA lenders require it, and buyers who skip an independent inspection often discover deferred maintenance on hydro jetting units that materially affects both valuation and loan terms after closing
- ✗Failing to verify that commercial maintenance contracts are assignable to the buyer — many municipal and restaurant grease trap accounts have clauses requiring customer consent for assignment, and discovering this post-LOI can delay or derail a deal
- ✗Accepting the seller's add-back schedule without independent verification — owner-operated drain cleaning businesses frequently run personal vehicles, family wages, and non-business expenses through the P&L, and lenders will scrutinize every add-back with documentation requirements
- ✗Structuring the seller note incorrectly — if the seller note is not placed on full standby and subordinated to the SBA loan per SBA Standard Operating Procedures, it will not count toward the equity injection and the deal structure will need to be renegotiated
- ✗Choosing a generalist SBA lender unfamiliar with equipment-heavy home services acquisitions — lenders who do not understand how to underwrite a hydro jetting truck fleet or a commercial drain maintenance contract portfolio will slow the process and may require unnecessary conditions
Lender Tips
- Work exclusively with SBA Preferred Lender Program (PLP) lenders who have closed home services or trades acquisitions — they have delegated SBA approval authority which cuts 3–6 weeks off the timeline compared to non-PLP lenders
- Present a clean, organized loan package from day one — include a detailed add-back memo, an equipment inventory with maintenance logs, and a customer concentration report segmented by residential, commercial, and municipal accounts to demonstrate revenue quality
- Demonstrate relevant industry experience in your business plan — lenders give more favorable terms to buyers with a plumbing or trades background, or who have committed to hiring an experienced operations manager if they lack direct technical experience
- Get your equity injection documented early — SBA lenders require a paper trail showing that your down payment funds have been seasoned in your account for at least 60–90 days; last-minute transfers or gift letters create underwriting delays
- Ask your lender about working capital inclusion — many buyers focus solely on the purchase price but forget that acquiring a drain cleaning business with a fleet of trucks and multiple technicians requires 2–3 months of operating capital; build this into your loan request from the start

Frequently Asked Questions
Can I use an SBA loan to buy a drain cleaning business if I don't have a plumbing license?
Yes, you can acquire a drain cleaning or hydro jetting business without holding a personal plumbing license, provided the licensed technicians and operators remain with the business post-acquisition. SBA lenders will want to see a clear retention plan for your licensed technicians — including employment agreements and competitive compensation — and will look favorably on buyers who can demonstrate relevant management experience in the trades or home services sector. If the seller holds the key operating license and plans to exit, you will need to ensure a licensed replacement is in place before or at closing.
How long does it take to close an SBA loan for a hydro jetting business acquisition?
Most SBA 7(a) acquisitions in this space close in 60–90 days from a signed LOI, assuming the buyer is organized, the seller has clean financials, and a PLP lender is engaged from the start. The biggest time variables are the equipment appraisal, which can take 2–3 weeks for a multi-truck fleet, and SBA approval, which is faster through PLP lenders who have delegated authority. Complex deals with municipal contract assignments or unresolved equipment liens can extend the timeline by 2–4 weeks.
Will the SBA loan cover both the goodwill and the equipment in a drain cleaning acquisition?
Yes — SBA 7(a) loans are specifically designed to finance both tangible assets like hydro jetting trucks, CCTV camera systems, and vacuum excavators, as well as intangible goodwill representing the brand, customer relationships, and commercial maintenance contracts. The lender will require a business valuation and an independent equipment appraisal to support the collateral position, but a single SBA 7(a) loan can cover the full acquisition price including all asset classes.
What debt service coverage ratio do lenders require for a drain cleaning business acquisition?
Most SBA lenders require a minimum debt service coverage ratio (DSCR) of 1.25x, meaning the business must generate at least $1.25 in adjusted cash flow for every $1.00 of annual loan payment. For a drain cleaning business generating $400,000 in SDE and a $2M acquisition financed over 10 years at current rates, the annual debt service would be approximately $270,000–$290,000, producing a DSCR of roughly 1.38x–1.48x — comfortably above the lender threshold. Lenders will also look favorably on a strong mix of recurring commercial maintenance contracts as a stability indicator.
Can a seller note be used to reduce my down payment on an SBA drain cleaning acquisition?
Yes, a seller note can be used to reduce your out-of-pocket equity injection — but it must be structured correctly. The SBA requires that any seller note used to meet the equity injection requirement be placed on full standby for the entire life of the SBA loan, meaning the seller receives no principal or interest payments until the SBA loan is paid off. When structured this way, a 10% seller note on a $2M deal ($200,000) combined with a 10% buyer equity injection ($200,000) satisfies the full 20% equity requirement, which is a common and lender-accepted structure in this industry.
What insurance do SBA lenders require when buying a drain cleaning business?
SBA lenders will require evidence of adequate commercial insurance at or before closing. For a drain cleaning and hydro jetting acquisition, this typically includes general liability insurance (minimum $1M per occurrence, $2M aggregate), commercial auto insurance covering all hydro jetting trucks and service vehicles, workers compensation coverage for all technicians, and an umbrella policy of $1M–$5M depending on the fleet size and revenue volume. Given the liability exposure associated with sewer line damage claims during high-pressure jetting operations, lenders will scrutinize coverage limits carefully. Buyers should also obtain a new policy in their entity name prior to closing rather than relying on an assignment of the seller's existing policy.
