Mechanics Liens + Collections for Service Business
Why this matters
When a customer doesn't pay, you have legal options - but the mechanics lien (the construction lien, the materialman's lien, varies by state) is the most powerful, time-sensitive, + state-specific tool. Miss the filing deadline, you lose the right entirely + your remaining option is small-claims court. The contractor who understands their state's lien law collects on jobs other contractors write off; the one who doesn't loses 1 - 4% of revenue annually to bad debt that lien rights could have recovered.
What a mechanics lien is
A statutory right that lets a contractor / subcontractor / materials supplier place a lien on real property they've improved. If the customer doesn't pay, the property cannot be sold or refinanced without satisfying the lien first. The lien creates leverage to get paid.
Critical: lien rights are STATE-SPECIFIC + TIME-SENSITIVE. Every state has its own statute. Filing deadlines range from 30 to 180 days post-completion. Miss the deadline, no lien rights remain.
When lien rights apply
Generally:
- Real property improvement (residential or commercial)
- Contractor / subcontractor / supplier who provided labor or materials
- Work was performed under valid contract (written or implied)
Doesn't apply to:
- Service work on existing property that doesn't IMPROVE it (e.g., cleaning, lawn mowing - service-only without improvement typically excluded)
- Some states exclude residential homestead property from liens
- Some property types (government, religious, etc.) have specific rules
State-by-state variation
Filing deadlines post-completion: Texas 15 days (original) / 60 days (sub); California 90 days (direct) / 30 days after Notice of Completion; Florida 90; NY 4 months residential / 8 commercial; Pennsylvania 6 months; most 60 - 180 days. Preliminary notice: CA 20-day, TX 15-day, FL 45-day from start. Each state differs - always consult state-specific guide or attorney.
The lien process
- Pre-lien notice (required in many states): sent within 15 - 45 days of starting work; informs customer their property may be liened; preserves right to lien later.
- Contract performance: provide labor/materials per contract; generate documentation (signed contract, change orders, invoices, daily logs).
- Invoice + collection attempts: send invoice with due date; follow up at 30/45/60 days; pre-lien notice + demand letter.
- Enforce lien (if still unpaid): within statutory enforcement period (90 - 180 days post-filing); file lawsuit to foreclose; court hearing; judgment + sale to satisfy (rare - customer usually pays first).
Standard collection process (before lien)
Day 1 invoice with clear terms; Day 30 friendly past-due email/SMS; Day 45 phone call; Day 60 certified letter with consequences (lien, attorney, credit reporting); Day 75 - 90 lien filing OR attorney engagement; Day 90+ small claims court or enforcement.
Lien for excluded trades
Service-only trades (lawn care, cleaning, pest control, carpet cleaning) often don't have lien rights because work is maintenance, not improvement. Alternatives: small claims court, collections agency, credit reporting (B2C debt), attorney letter, write off after good-faith attempts.
Customer dispute (lien at risk)
If customer disputes work OR amount: gather discovery (photos, contract, change orders, communications), attempt owner-to-owner resolution, then mediation (cheaper) or arbitration (faster). Lien may still be filed during dispute to preserve rights; settle for reduced amount if dispute legitimate. NEVER file lien for fraudulent amounts - anti-lien-fraud statutes carry penalties.
Lien priority + when not to file
Priority: first-in-time wins generally; tax/IRS liens have super-priority; multiple contractor liens compete. File sooner > later to preserve priority. Don't file when customer is in genuine financial trouble (bankruptcy imminent, lien subject to automatic stay), when customer's dispute has merit (you didn't perform to spec, lien may fail in court), or when amount too small.
Lien waiver + retainage
When customer pays, sign "lien waiver" releasing lien rights for that work. Types: Conditional (release on payment received - safer for contractor), Unconditional (release regardless - risky for contractor), Progress (released for payment to date), Final (released entirely). Read language carefully. Retainage: customer holds 5 - 10% until completion + acceptance, common commercial; lien deadline starts after final completion + retainage release.
Pre-job risk assessment
Before starting work: credit check for high-value commercial ; references from other contractors who worked for customer; required deposit for residential (20 - 50% on major work); progress payments scheduled in contract; lien-rights notice at start; customer payment history tracked in CRM.
Collection options
In-house (recommended through 60 - 90 days past due): owner's time only, free except opportunity cost, higher recovery if pursued aggressively. Collection agency (after 90 - 120 days): 25 - 50% commission, aggressive means, net 50 - 75% of debt recovered. Attorney (high-value or lien-required).
Common mechanics lien mistakes
Missing the deadline: most common; lose right entirely.
Lien on wrong property: legal description must match exactly. Get it from county records, not customer.
Wrong lien amount: include only what's actually unpaid + actually for that property.
No pre-lien notice when required: lien void in some states.
Lien on homestead-protected property: invalid in some states.
Not enforcing within statutory period: lien expires.
Filing lien for personal grudge: anti-lien fraud penalties.
NEVER file a mechanics lien without first verifying your state's specific requirements + your specific eligibility. Each state has different lien statutes, different deadlines, different notice requirements, + different property protections. A lien filed incorrectly = void + can expose YOU to legal action from the customer for slander of title. When uncertain, consult a construction attorney in your state - typically consultation for lien-specific advice. The cost of legal advice is dwarfed by the cost of a wrongly-filed lien.
