Estimating masonry cost means building up from measured quantities to a bid price. The buildup is: materials + labor + equipment = direct cost, then + overhead = job cost, then + profit = bid price. Each layer has a range, not a fixed number, and your actuals depend on region, wall type, block or brick size, and risk. Masonry is trade specific: you price by the square foot of wall, by the piece for brick and block, by the cubic yard for grout and concrete fill, by the ton for rebar and reinforcement, and you carry a waste factor because blocks break and mortar gets dropped.
What You Are Pricing
You are pricing a masonry scope, and that scope changes with the system. Concrete masonry units, or CMU, are priced by the piece or by the square foot of wall, with the block size, weight, and finish built into the unit. Brick veneer is priced by the square foot or by the thousand, with the brick, mortar, ties, and flashing rolled in. Stone veneer is priced by the square foot, with natural stone running higher than manufactured. Solid brick and structural CMU are priced by the square foot with reinforcement and grout fill added. Mortar is priced by the bag or by the cubic foot, and grout fill by the cubic yard. Rebar and joint reinforcement are priced by the linear foot or by the ton. Flashing, weeps, and ties are priced by the piece or by the linear foot. Do not mix systems in one line item: a veneer line and a structural wall line behave differently in the field and in the budget.
Direct Cost Buildup
Direct cost is what you spend on the job: materials, labor, equipment, and any subcontractor buyout. Build each line item the same way so you can compare bids.
- Materials: Block and brick priced per piece from a real supplier quote, with a waste factor of 3 to 8 percent for breakage and cuts. Mortar and grout priced per bag, then converted to the wall area. Rebar and joint reinforcement priced per linear foot or per ton. Ties, flashing, and weeps priced per piece.
- Labor: Mason and tender hours times the fully burdened wage. A burdened rate includes wages plus workers comp, insurance, payroll taxes, and benefits. Figure 0.04 to 0.08 labor hours per square foot for CMU, more for brick veneer and natural stone because of layout and cutting.
- Equipment: Mortar mixers, scaffolding, forklifts or lulls for material handling, and grout pumps. Charge mixer and lift hours to the day they are used, because idle time kills margin. Add a setup and teardown allowance.
- Subcontractors: If you buy out the grout fill, the rebar, or the flashing, the sub price replaces your labor and material on that line. Still carry overhead and profit on top of the sub.
Step by Step Cost Estimate
Work the numbers in the same order every time so nothing falls through.
- 1. Quantify the scope: Take wall square footage from the elevations, count blocks and bricks by size, measure grout fill in cubic yards, and tag each line by wall type and reinforcement.
- 2. Price materials: Multiply block and brick counts by the supplier quote, add the waste factor, then price mortar, grout, rebar, and flashing. Get a real quote, do not use a stale price sheet.
- 3. Price labor: Estimate crew hours from your production rate by wall type, then multiply by the burdened wage. Add a crew hour allowance for corners, bond patterns, or heavy cutting.
- 4. Add equipment: List the mixer and lull days, then add scaffolding, grout pump, and rigging. If the job needs a forklift for second floor work, price that now.
- 5. Add subcontractor buyouts: Drop in quoted sub prices for grout pump or rebar, and mark them up for overhead and profit.
- 6. Apply overhead: Roll up direct cost, then apply your overhead percentage from your books.
- 7. Apply profit: Apply your profit percentage to direct cost plus overhead. That gives you the bid price.
Worked Example
For a representative masonry scope, 1,200 SF of 8 inch CMU wall, 1,350 blocks, 60 bags of mortar, 8 CY of grout fill, a typical direct cost buildup is:
- Materials: 1,350 blocks at $2.40 = $3,240. Mortar 60 bags at $12 = $720. Grout fill 8 CY at $160 = $1,280. Rebar and joint reinforcement $400. Ties and flashing $260. Material total $5,900.
- Labor: 1,200 SF at 0.06 hr/SF = 72 hours. Plus tender hours 24. Total 96 hours at a burdened wage of $42/hr = $4,032.
- Equipment: Mixer two days at $120/day = $240. Lull one day at $450. Scaffolding and rigging $400. Equipment total $1,090.
- Direct cost: $11,022.
- Overhead at 15 percent: $1,653.
- Profit at 10 percent: $1,268.
- Bid price: $13,943, or about $11.62 per square foot of wall.
Numbers are illustrative and vary by region, project size, and material choice. Use them as a sanity check, not a bid.
Factors That Move the Number
Several variables swing masonry estimates more than people expect. Wall type is the biggest: structural CMU runs higher than veneer because of grout fill, rebar, and engineering. Brick and block size drive labor, because larger units lay faster per square foot but cost more per piece. Bond pattern matters, because a running bond is fast and a stack bond or basket weave is slow and cuts more. Height and access are next, because work above 8 feet needs scaffolding or a lull, and that adds equipment and labor. Reinforcement and seismic requirements also bite, because grout fill and rebar add cubic yards and tonnage to every line. Weather and season matter too, because cold weather masonry needs enclosures and heaters, and that adds cost per square foot.
Common Mistakes
- Using a markup instead of a margin. They are not the same. A 10 percent markup on $100 is $110, a 10 percent margin on $100 is $111.
- Forgetting to burden the labor rate before marking up. Burdened wage, not take home pay, goes in the estimate.
- Leaving out the waste factor. Blocks break, mortar gets dropped, and cuts add up on every job.
- Setting one profit number for every job regardless of risk. A small complex wall should carry more profit than a large simple one.
- Not checking the bid price against a square foot or unit cost sanity check. If your price is double the market, find the error before you submit.
- Quoting materials from a stale price sheet. Block, brick, and cement move with the market, get a current quote.
Putting It Together
A masonry estimate is a buildup, not a guess. You measure the scope, price block and brick with a real supplier quote and a waste factor, build labor from crew hours times the burdened wage, add equipment and sub buyouts, then apply your overhead and profit from your books. The bid price is the sum of those layers, and your cost per square foot of wall is the check that tells you whether the number is sane. Run the buildup the same way on every bid and your numbers will compare across jobs and over time.
