Introduction
Most masonry budget overruns aren’t caused by expensive bricks — they’re caused by forgotten line items. The footing nobody priced, the lintels nobody counted, the second delivery because the waste allowance was zero, the permit fee discovered at the building department counter. A checklist doesn’t make you a better estimator; it makes you a complete one.
The Masonry Cost Calculator handles the core math — units, mortar, labor, total. This checklist covers everything around it: every measurement to take, every cost line to capture, every confirmation to get before you order materials or sign a contract. Work through it once per project and the estimate will have no gaps.
Phase 1: Project Definition
- ☐ Wall function defined: freestanding, retaining, structural/load-bearing, or veneer?
- ☐ Material selected: brick, block, natural stone, or manufactured veneer (see the material guide).
- ☐ DIY, pro, or hybrid decided (see the DIY vs pro guide).
- ☐ Local building authority contacted: permit needed? engineering needed? (see the code compliance guide).
- ☐ Boundary/neighbor issues checked for walls near property lines.
Phase 2: Measurement
- ☐ Every wall face measured: length × height, recorded per face.
- ☐ Height measured from top of footing to top of final course.
- ☐ All openings over ~0.5 m² measured at the structural opening and subtracted.
- ☐ Corners, piers, returns, and steps decomposed into rectangles — no double-counted corners.
- ☐ Below-grade courses included in the height.
- ☐ Photos taken of each elevation with dimensions annotated.
- ☐ Net area calculated and sanity-checked (see the estimating guide).
Phase 3: Quantities
- ☐ Units = net area × coverage/m² × (1 + waste%) — 60/m² brick, 12.5/m² block, by area for stone.
- ☐ Waste ≥ 5% (≥ 10% for complex walls) — never zero.
- ☐ Mortar = net area × rate/m² (0.025 brick, 0.018 block), ÷ 0.016 m³ per bag, rounded up.
- ☐ Quantities rounded to order units: pallets for units, full bags for mortar.
- ☐ Single-batch ordering confirmed with supplier (color matching).
- ☐ 2–3% repair stock held back deliberately.
Phase 4: Cost Lines — The Full Capture
Every line below belongs in the budget. Check each off as priced or explicitly not applicable:
- ☐ Masonry units (with waste and pallet rounding).
- ☐ Mortar (bags or sand + cement).
- ☐ Labor — per m², with the exact unit specified, in writing.
- ☐ Footing/foundation concrete + excavation.
- ☐ Reinforcement and grout (if reinforced blockwork).
- ☐ Lintels — one per opening, sized for the span.
- ☐ Wall ties (cavity walls).
- ☐ Coping/caps — per linear meter.
- ☐ Drainage aggregate, drain tile, waterproofing (retaining walls).
- ☐ Scaffolding/access hire.
- ☐ Delivery charges.
- ☐ Waste disposal / skip hire.
- ☐ Permit fees.
- ☐ Engineering/design fees (if required).
- ☐ Contingency: 5–10% on the total.
Typical ranges for each line are in the cost guide; the common mistakes guide shows what each omission costs.
Phase 5: Quotes and Verification
- ☐ 2–3 itemized mason quotes obtained (materials, labor/m², extras separated).
- ☐ Quotes converted to cost per m² laid for comparison.
- ☐ Exclusions confirmed in writing — what’s not included in each quote.
- ☐ Calculator total cross-checked against hand math (see the formula guide).
- ☐ Imperial/metric cross-check done if working across systems.
- ☐ Previous work of the chosen mason viewed or referenced.
Phase 6: Pre-Build
- ☐ Permit approved and inspections scheduled (footing before pour!).
- ☐ Materials delivered and stored off the ground, covered.
- ☐ Weather window checked — no freezing nights or storms in the first 48 hours.
- ☐ Scope split agreed in writing (for DIY-assisted or hybrid projects).
- ☐ Waste responsibility agreed (who pays for breakage beyond the allowance).
Worked Mini-Example: Checklist in Action
A 6 m × 1.0 m = 6 m² brick garden wall run through the checklist: net area 6 m² (no openings); units 6 × 60 × 1.08 = 389 → 389 bricks; mortar 6 × 0.025 = 0.15 m³ → 10 bags; materials (389 × $0.55) + (10 × $6.50) = $213.95 + $65.00 = $278.95; labor 6 × $55 = $330.00; footing (6 × 0.4 × 0.25 = 0.6 m³ × $140) = $84.00; coping 6 × $8 = $48.00; delivery $40.00; subtotal $780.95; + 5% contingency $39.05 = $820.00 total.
Imperial check: 6 m² = 64.58 ft²; 389 ÷ 64.58 = 6.02 bricks/ft² with waste ✓; labor 64.58 × $5.110 = $330.00 ✓. Sum-check: $213.95 + $65.00 + $330.00 + $84.00 + $48.00 + $40.00 = $780.95; × 1.05 = $820.00 ✓.

Frequently Asked Questions
How long does the checklist take to work through?
About 30–60 minutes for a typical garden wall once measurements are in hand. It saves multiples of that in avoided rework and surprise costs.
Which checklist phase do people skip most?
Phase 4’s extras — footings, lintels, coping, and delivery. The wall gets priced; the project doesn’t.
Do I need the full checklist for a small wall?
Yes, but it goes faster — many lines check off as “not applicable” in seconds. The value is in confirming they’re not applicable rather than assuming it.
What contingency is right?
5% for pro-built work with itemized quotes; 10% for DIY or loosely quoted projects. Contingency covers unknowns, not arithmetic — fix the math with the checklist.
Should I print this checklist?
Print it or copy it into your notes app and check items off on site. A checklist in your head is a wish list.
What if a quote is missing checklist lines?
Ask the mason to price them or confirm exclusion in writing. An unpriced line is an unbounded cost — get it bounded before signing.
How do I handle mid-project changes?
Re-run the affected checklist phases: re-measure the changed area, re-compute quantities, and get the cost impact in writing before the work proceeds. Verbal change orders are where budgets die — a one-line email confirmation (“add 2 m of wall at the quoted $55/m² = $110”) takes a minute and prevents disputes.
Get Your Number
Print the checklist, walk your project through all six phases, and run the quantities through the Masonry Cost Calculator as you go. When every box is checked and the sum reconciles, you have a budget — not a guess.
Disclaimer: Calculator results are planning estimates based on the dimensions and rates you enter. This checklist is a planning aid, not professional advice. Verify all quantities, prices, and code requirements locally, and consult a licensed professional or local building authority for structural or code-related decisions.
