How to collect an unpaid masonry invoice
Published May 14, 2026
Short answer
Masonry and concrete work involves significant material costs upfront -- concrete, block, brick, and mortar are ordered and delivered before labor begins. A 30-50% deposit is standard on any job over $2,000 and is not negotiable for custom work. Document footings, reinforcement, and pour depth with photographs at each stage because post-cure disputes over cracking are common. A mechanic's lien on the property is your primary recovery tool if a balance goes unpaid after 30 days.

A 40-foot block retaining wall might have $4,000-6,000 in block, cap, gravel, and rebar before a single hour of labor is billed. Requiring a deposit before material ordering is not a preference -- it is a financial necessity. Any masonry contractor who starts work without a deposit is fronting that material cost personally for weeks or months.
Photograph the job at every milestone: excavation depth, footing dimensions, rebar placement, initial pour, form stripping, and final finished surface. Cracks are the most common post-completion dispute in concrete work, and almost every crack is attributable to ground movement, cure conditions, or expansion joint spacing -- rarely to pour quality. Your documentation of proper technique is what distinguishes your work from a pre-existing condition or a weather event.
Staged billing works best for larger masonry projects: deposit to cover materials, a progress payment at structural completion (footings poured, block set), and final balance at project completion. Do not release the final bill until punch-list items are resolved. For smaller jobs (a single retaining wall section, a patio pour), a 50% deposit and balance at completion is simpler.
If a balance goes past due, place a call on day 3 before considering escalation. Most residential masonry customers are not avoiding payment -- they are slow. A friendly reminder call resolves the majority of overdue balances within the first week. For commercial jobs, follow up with the AP contact directly rather than the project manager who hired you.
The mechanic's lien is your escalation tool of last resort. In most states, masonry contractors have the right to file a lien on the improved property if payment is not made within the statutory period. The deadline varies by state (typically 60-120 days from last day of work), so do not let a disputed invoice sit past 45 days without action. Filing a lien does not guarantee collection, but it creates a cloud on title that motivates payment when the owner tries to refinance or sell.
