Is Your Drain Cleaning Business Ready to Sell?

Work with your accountant to produce clean profit and loss statements for the past three fiscal years. Identify and document all owner add-backs — personal vehicle expenses, owner health insurance, discretionary travel, and any personal expenses run through the business. Buyers and SBA lenders will require this to calculate your true SDE and support your asking price.

Stop running personal expenses through the business immediately. Open separate accounts if needed. Buyers discount valuations heavily when they cannot distinguish between business income and owner lifestyle spending, and it complicates SBA loan underwriting.

Break down your revenue for the past 24 months into residential emergency calls, commercial maintenance accounts, municipal contracts, and grease trap or storm drain work. This segmentation lets buyers quantify recurring versus one-time revenue and is a primary focus in due diligence.

Prepare an accounts receivable aging report and resolve any long-outstanding balances. Buyers will ask about collections history, and unresolved receivables from commercial accounts can raise concerns about customer payment reliability and contract enforceability.

Pull UCC lien searches and compile all outstanding equipment financing. Buyers need to know exactly what debt is attached to the assets they are acquiring, particularly for hydro jetting trucks, vacuum excavators, and camera inspection systems that are central to operations.

Create a detailed asset register listing every hydro jetting unit, CCTV camera system, vacuum truck, service van, and trailer. Include purchase dates, current mileage or hours, maintenance logs, remaining warranties, and fair market values. Third-party equipment appraisals are strongly recommended and will be required for SBA financing.

Buyers and their inspectors will identify aging or poorly maintained jetting trucks, cracked high-pressure hose assemblies, malfunctioning CCTV camera heads, and vehicles with high deferred maintenance. Address these issues proactively rather than allowing buyers to use them as negotiating leverage to reduce your price.

Write or formalize SOPs for every core operational function including how jobs are dispatched, how technicians are routed, how estimates are prepared for commercial drain maintenance bids, how CCTV inspection reports are delivered to clients, and how customer follow-up is handled. This demonstrates the business runs as a system, not around the owner.

Create a clear org chart showing the technician team, any supervisory roles, office or dispatch staff, and the owner's current responsibilities. Document each employee's licenses (plumbing, contractor registrations), drain cleaning certifications, CDL status for truck operators, and current compensation including any bonus structures.

If you are still running dispatch and invoicing on paper or spreadsheets, transition to a field service management platform used commonly in the trades. This creates a digital record of job history, customer accounts, equipment usage, and revenue that buyers can review and transfer to their own systems.

Compile executed copies of every recurring service agreement — restaurant grease trap maintenance, property management drain programs, municipal storm drain contracts, and commercial facility maintenance accounts. Include contract terms, renewal dates, annual revenue per account, and whether contracts are assignable to a buyer.

Prepare a report showing what percentage of total revenue each customer represents. Buyers and lenders get nervous when any single account exceeds 15–20% of revenue. If you have dangerous concentration, begin diversifying your client base actively in the 12–18 months before your target sale date.

If any of your major commercial maintenance agreements are approaching expiration, prioritize renewing them for 1–2 year terms before you list the business. Buyers will heavily discount or discount the value of contracts that are month-to-month or expiring within 6 months of closing.

Actively solicit Google reviews from satisfied residential and commercial customers in the months before going to market. A profile with 4.5+ stars and 100+ reviews signals strong inbound organic demand that buyers prize — particularly home services platforms looking for established local brand equity they can scale.

Compile data showing where your phone calls and job requests come from — Google search, Google Local Services Ads, referrals, repeat commercial accounts, or direct relationships. Show cost per lead and average job ticket by source. This helps buyers understand the marketing infrastructure and what it will cost to maintain revenue post-acquisition.

Confirm your state contractor license, local business licenses, any specialty drain or sewer contractor registrations, and CDL requirements for your hydro jetting truck operators are all current and in good standing. Determine which licenses are held in the owner's name versus the business entity — those held personally will need to transfer or the buyer will need to obtain their own.

Work with your commercial insurance broker to confirm you have adequate general liability coverage for sewer line damage claims, commercial auto coverage for your entire fleet, and environmental or pollution liability coverage for jetting operations. Buyers will require certificates of insurance and claims history for the past 3–5 years.

Identify and resolve any open claims from sewer line damage incidents, property flooding from jetting operations, or disputes with commercial clients over service failures. Unresolved litigation is a material deal risk that buyers will require to be resolved or escrowed before closing.

Confirm your LLC or corporation is in good standing with the state, annual reports are filed, and ownership structure is clearly documented. If you have a partner buyout or any informal ownership arrangements, resolve them formally before going to market.

Determine whether any of your experienced drain technicians or crew leads have employment agreements, non-solicitation clauses, or any arrangements that could affect a buyer's ability to retain them. If key employees have no agreements, consider implementing retention incentive plans tied to a business sale event.

Select an advisor who has closed drain cleaning, plumbing, or home services transactions and understands how to position recurring commercial contracts, fleet value, and technician teams to the right buyer universe. Avoid general business brokers without trades or field services experience — they will undervalue your commercial accounts and equipment.

Work with your advisor to produce a CIM that presents your financial summary, equipment fleet, customer base segmentation, recurring revenue documentation, team overview, and growth opportunities in a format familiar to serious buyers and their lenders. A professional CIM signals that the seller is organized and prepared, which increases buyer confidence.

Work with your advisor to plan when and how to communicate the sale to your technician team. Disclosing too early creates retention risk; disclosing too late creates trust issues at closing. Consider retention bonuses tied to the closing date to keep your crew stable through the transaction process.

Define how long you are willing to stay involved post-closing for training, customer introductions, and operational handover. Most buyers expect 60–180 days of seller involvement. For businesses with strong owner relationships in commercial accounts, a structured transition period helps buyers retain accounts and reduces earnout risk tied to revenue retention.

Work with your advisor to establish an asking price grounded in your documented SDE and current market multiples for drain cleaning businesses — typically 2.5x–4.5x SDE depending on recurring revenue mix, equipment condition, and team quality. Overpricing delays your sale; underpricing leaves significant money on the table.
