Verify licenses, job costing accuracy, crew stability, and backlog quality before closing on a residential outdoor contractor acquisition.
Acquiring a deck and fence business in the $1M–$5M revenue range offers strong cash flow potential, but these owner-operated businesses carry specific risks that generic due diligence misses. Contractor license transferability, seasonal revenue swings, thin subcontractor benches, and undocumented job costing can erode returns quickly if not addressed before close. This checklist is organized by the five highest-leverage due diligence categories for outdoor residential contractor acquisitions, helping buyers using SBA 7(a) financing or direct seller financing validate every material assumption before signing.
Verify all contractor licenses, permits, and bonding requirements are current, transferable, and free of violations that could disrupt operations post-close.
Confirm all state and local contractor licenses are active and transferable to a new owner.
Some jurisdictions require re-licensing under new ownership, delaying operations and revenue by weeks or months.
Red flag: Key licenses are held personally by the seller with no clear transfer or re-application pathway.
Review all pulled permits on jobs completed in the last 3 years for final inspection sign-off.
Unpermitted or uninspected work creates warranty liability and potential stop-work orders on future projects.
Red flag: Multiple jobs lack final permit inspections or were built without required permits.
Verify current general liability insurance, workers' compensation coverage, and contractor bond amounts.
Gaps in coverage create uninsured liability exposure and may disqualify the business from larger contracts.
Red flag: Coverage lapses, claims history with multiple payouts, or bond cancellations in the past 24 months.
Check for outstanding liens, warranty claims, or unresolved disputes on completed projects.
Successor liability in an asset purchase can still attach if liens are discovered post-close.
Red flag: Any mechanic's liens filed against customers or unresolved warranty disputes exceeding $10K.
Validate that reported SDE and gross margins are accurate, consistently tracked by job type, and supported by tax returns and QuickBooks records.
Reconcile 3 years of tax returns against P&Ls and bank statements for revenue and expense accuracy.
Owner-operated contractors frequently blend personal and business expenses, inflating reported SDE.
Red flag: Material discrepancies between tax returns and P&Ls or unexplained revenue spikes in the trailing year.
Review job costing reports by project type — decks versus fencing — for gross margin consistency.
Inconsistent margins by job type signal poor estimating discipline or undisclosed cost overruns.
Red flag: Gross margins vary more than 15 percentage points across comparable project types without explanation.
Validate all owner add-backs with documentation including personal auto, health insurance, and non-recurring expenses.
Unsupported add-backs directly inflate the purchase price and reduce actual post-acquisition cash flow.
Red flag: Add-backs exceed 20% of reported EBITDA without invoices or clear business-versus-personal classification.
Analyze seasonal revenue distribution by month to quantify winter revenue gaps and cash flow timing.
Deck and fence revenue concentrates in spring and summer, creating real working capital strain in Q1 and Q4.
Red flag: Fewer than 7 active revenue months annually with no maintenance or service revenue to offset winter gaps.
Assess the stability, diversity, and transferability of the customer base, including referral sources and any recurring service revenue streams.
Calculate the revenue percentage attributable to the top 5 customers over the trailing 24 months.
High concentration means a single lost client can materially impair post-acquisition revenue.
Red flag: Any single customer representing more than 20% of trailing 12-month revenue.
Identify percentage of revenue from referrals, repeat clients, and maintenance or staining contracts.
Referral and repeat revenue signals brand strength; maintenance contracts provide predictable recurring cash flow.
Red flag: Less than 30% of revenue from repeat or referral sources with no maintenance contract program in place.
Review online reputation including Google reviews, count, rating, and recency of customer feedback.
A 4.5+ star rating with 50+ reviews drives inbound leads and reduces customer acquisition cost post-close.
Red flag: Fewer than 25 Google reviews, rating below 4.0, or multiple unresolved negative reviews about workmanship.
Assess whether key customer relationships are tied to the owner personally or to the business brand.
Owner-dependent customer relationships are at high attrition risk during and after ownership transition.
Red flag: Top clients explicitly state they work with the business because of the seller personally.
Evaluate crew stability, foreman capability, subcontractor depth, and retention risk for the employees essential to project delivery post-close.
Identify all W-2 employees and 1099 subcontractors and confirm tenure, role, and compensation for each.
Crew depth and tenure directly determine the buyer's ability to deliver projects without the seller on-site.
Red flag: Majority of field labor is 1099 subcontractors with no exclusivity and active relationships with competitors.
Assess whether any foreman or estimator can run projects independently without seller involvement.
A capable foreman reduces key-man dependency and supports a cleaner, faster ownership transition.
Red flag: No employee capable of estimating or managing a job from site visit to final inspection without the seller.
Request non-compete and non-solicitation agreements for key foremen, estimators, and sales staff.
Departing crew can take trained labor, supplier relationships, and customer referrals to a competitor.
Red flag: No employment agreements exist and key foremen have expressed interest in starting their own operations.
Verify subcontractor bench depth and whether preferred subs are available to a new ownership group.
A thin sub bench creates scheduling delays and margin compression when preferred crews are unavailable.
Red flag: Only one or two subcontractors capable of specialty work such as composite decking or ornamental iron fence.
Verify the quality of signed contracts, deposit liabilities, and backlog documentation to support revenue projections and SBA loan underwriting.
Review all signed contracts in the current backlog including scope, deposit received, and projected start dates.
Backlog quality directly supports revenue projections used in SBA underwriting and purchase price negotiation.
Red flag: Backlog consists primarily of verbal commitments or unsigned proposals with no deposits collected.
Calculate total customer deposit liability and confirm funds are held in a segregated account.
Deposits collected but not segregated represent real cash flow risk if projects are delayed or cancelled post-close.
Red flag: Deposits commingled with operating accounts and no reconciliation of completed versus outstanding deposit obligations.
Evaluate whether deal structure includes earnout, seller note, or transition employment for the seller.
Seller retention during transition reduces customer attrition and supports license continuity in some states.
Red flag: Seller unwilling to stay involved for any transition period despite holding all key customer relationships.
Confirm SBA eligibility including seller note subordination requirements and injection source documentation.
SBA 7(a) loans require 10–15% equity injection and seller note must be on full standby during the loan term.
Red flag: Buyer equity injection is borrowed or gifted without documentation, triggering SBA eligibility concerns.

Vetted targets with diligence packages — skip the cold search.
Yes. Deck and fence businesses are SBA-eligible when they have at least 2 years of operating history, a DSCR above 1.25x, and documentable SDE of $300K or more. Most SBA deals in this industry require a 10–15% equity injection, and the seller is often asked to carry a 10–20% seller note on full standby for the loan term. Work with an SBA-preferred lender experienced in trades and contractor business acquisitions to accelerate approval.
Key-man dependency is the most common deal-killer. When the seller handles all estimating, customer relationships, and project oversight personally, revenue is at significant attrition risk post-close. Buyers should confirm at least one capable foreman or estimator can operate independently and negotiate a seller transition period of 6–12 months as a condition of closing.
Request copies of all signed contracts with customer signatures, deposit amounts received, and scheduled start dates. Cross-reference deposit totals against bank statements to confirm funds were actually collected. Any project in the backlog without a signed contract and deposit should be excluded from revenue projections used in your offer or SBA loan application.
Deck and fence businesses in the $1M–$5M revenue range typically trade at 2.5x–4.5x SDE. Businesses at the higher end of that range have documented recurring maintenance revenue, a foreman-led workforce, clean job costing records, and diversified customer bases. Businesses with heavy owner dependency, seasonal gaps below 7 active months, or customer concentration above 20% typically fall toward the lower end of the multiple range.
