Verify revenue quality, workforce stability, licenses, equipment condition, and digital reputation before you close on any HVAC, plumbing, landscaping, or trade services acquisition.
Acquiring a home services business in the $1M–$5M revenue range offers compelling cash flow, recession-resistant demand, and strong roll-up potential — but the risks are specific and often hidden. Owner-operator dependency, unverifiable recurring revenue, aging fleet equipment, and licensing gaps can erode deal value quickly post-close. This checklist gives buyers a structured framework across five critical due diligence categories to surface deal-killers early, negotiate with confidence, and protect your investment from day one.
Verify that reported revenue is real, repeatable, and not dangerously concentrated in a handful of accounts or one-time projects.
Pull 3 years of tax returns and match to internally prepared P&Ls line by line.
Discrepancies between tax returns and P&Ls often reveal unreported income claims or inflated add-backs that distort SDE.
Red flag: Seller cannot reconcile tax returns to P&L or refuses to provide all three years of filed returns.
Identify every customer representing more than 5% of annual revenue and calculate combined concentration.
A single commercial account or property manager driving 20%+ of revenue creates catastrophic churn risk post-close.
Red flag: Any single customer exceeds 15–20% of total revenue with no long-term contract in place.
Request a full schedule of active service agreements, maintenance contracts, and membership plans with renewal dates.
Recurring contract revenue at 30–40%+ of total revenue dramatically de-risks post-close cash flow.
Red flag: Seller describes recurring revenue verbally but cannot produce signed agreements or renewal documentation.
Analyze monthly revenue by service line for the trailing 24 months to identify seasonality and trend direction.
Declining revenue trends in the 24 months before sale are the single strongest predictor of post-close underperformance.
Red flag: Revenue declined more than 10% year-over-year with no credible explanation from the seller.
Assess whether the business can operate without the seller and whether the technician team will stay post-close.
Map every employee's role, tenure, certifications, and compensation against revenue contribution.
Losing two or three licensed technicians post-close can eliminate the business's ability to fulfill service agreements.
Red flag: One or more revenue-generating technicians have expressed interest in leaving or starting their own company.
Conduct confidential interviews with the seller to identify which employees know a sale is happening.
Premature disclosure without a retention plan triggers preemptive departures before close.
Red flag: Seller has already disclosed the sale broadly to staff without any retention incentive structure in place.
Evaluate whether a non-owner operational lead exists who manages scheduling, dispatch, and quality control.
Businesses without a second-in-command require the buyer to immediately fill an operations role at close.
Red flag: Seller is the sole dispatcher, quality controller, and customer relationship manager with no documented backup.
Review all employment agreements, non-competes, and independent contractor classifications for compliance risk.
Misclassified 1099 technicians create significant IRS and state labor liability that transfers to the buyer in an asset deal.
Red flag: Key technicians are classified as independent contractors but work exclusively and full-time for the business.
Confirm all trade licenses, contractor bonds, and insurance policies are current, transferable, and free of violations.
Obtain copies of every active trade license, contractor registration, and municipal permit with expiration dates.
Operating without required licenses post-close exposes the buyer to stop-work orders, fines, and customer liability.
Red flag: Any active license is held personally by the seller and is non-transferable to a new entity or buyer.
Verify general liability, workers' compensation, and commercial auto insurance coverage limits and claims history.
A history of frequent claims raises premiums post-close and may signal unsafe operational practices.
Red flag: Seller has open insurance claims, lapsed coverage periods, or cannot provide a five-year loss run history.
Search for unresolved liens, OSHA violations, BBB complaints, and state contractor board disciplinary actions.
Undisclosed regulatory violations or mechanics' liens can attach to assets and transfer liability to the buyer.
Red flag: State contractor board records show unresolved complaints, license suspensions, or disciplinary proceedings.
Confirm environmental compliance for any business handling refrigerants, chemicals, or hazardous waste disposal.
HVAC and pest control operators face EPA and state-level environmental liability that survives asset purchase structures.
Red flag: Business has no documented refrigerant handling logs or chemical disposal records required under EPA Section 608.
Assess the true condition and remaining useful life of all vehicles, tools, and equipment included in the transaction.
Conduct a physical inspection of every vehicle and major piece of equipment included in the asset purchase.
Deferred fleet maintenance is the most common hidden capex trap in home services acquisitions.
Red flag: Multiple vehicles have over 150,000 miles, deferred repairs, or no documented maintenance history.
Request maintenance logs, repair invoices, and current KBB or NADA valuations for all fleet vehicles.
Seller representations about fleet value are frequently overstated; independent valuation prevents overpaying for assets.
Red flag: Seller cannot produce maintenance records or repair invoices for any vehicle in the fleet.
Identify all specialized tools, diagnostic equipment, and machinery required to deliver core services and assess age.
Replacing a specialized diagnostic unit or piece of trade equipment can cost $10,000–$50,000 unplanned post-close.
Red flag: Core service equipment is more than 8–10 years old with no documented service history or replacement budget.
Build a 24-month forward capex projection covering vehicle replacements, tool upgrades, and technology investments.
Underfunded capex projections cause post-close cash flow shortfalls that jeopardize SBA loan servicing.
Red flag: Seller has made no capital investments in fleet or equipment in the three years preceding the sale.
Evaluate the digital foundation that drives inbound leads, new customer acquisition, and brand equity in the local market.
Audit Google Business Profile review count, average star rating, and response rate over the trailing 24 months.
Google reviews are the primary trust signal for residential home services buyers and directly drive call volume.
Red flag: Average rating below 4.2 stars, declining review velocity, or significant unresolved one-star complaints visible publicly.
Pull Google Local Services Ads performance data including lead volume, cost per lead, and badge status.
LSA accounts with Google Guaranteed status and established history are a transferable asset with meaningful lead value.
Red flag: LSA account is suspended, under review, or the Google Guaranteed badge has been revoked for background check failures.
Analyze organic search rankings for primary service keywords in the local market using SEMrush or Ahrefs.
Organic rankings built over years represent defensible, low-cost lead generation that paid advertising cannot replicate quickly.
Red flag: Website has received a Google manual penalty or has significant toxic backlink profile that depresses rankings.
Verify ownership and login access to all digital assets including website domain, Google Business Profile, and social accounts.
Inability to transfer digital assets post-close can eliminate the entire online lead generation infrastructure overnight.
Red flag: Seller does not own the website domain, or Google Business Profile is managed by a third-party agency with no transfer process.

Vetted targets with diligence packages — skip the cold search.
Customer concentration and recurring revenue verification. If a single customer or account represents more than 15–20% of revenue and there is no long-term contract in place, post-close churn can eliminate profitability within the first year. Request a full customer revenue schedule and cross-reference it against invoicing records before you proceed past LOI.
Request copies of every signed service agreement, maintenance contract, and membership plan with customer names, contract terms, renewal dates, and annual value. Cross-reference total contract value against the revenue reported on P&Ls. Then confirm that contracts are assignable to a new owner under their existing terms — many residential agreements have no-assignment clauses that require customer re-enrollment post-close.
Budget 5–10% of purchase price for near-term fleet and equipment capex unless the seller can document maintenance history and recent investment. Vehicles with over 150,000 miles, specialized equipment older than 8–10 years, and any deferred repairs identified during physical inspection should be quantified before close and either discounted from the purchase price or addressed via seller credit at closing.
Structure retention bonuses for key technicians payable 6–12 months post-close contingent on continued employment. Include seller cooperation and non-solicitation provisions in the purchase agreement. Where possible, negotiate a transition period of 90–180 days during which the seller actively introduces you to key staff. Identify a second-in-command before close who can serve as operational lead if the seller departs on schedule.
