Masonry Project Cost Estimator and Budget

For standard brick running bond projects, add a 5% to 10% waste factor to your total material count. For complex stone patterns or jobs requiring extensive cutting around windows and corners, increase this factor to 15% or 20%. This ensures you have enough stock to complete the job without paying for extra delivery fees mid-project.

Generally, you will need approximately three to four bags of mortar mix for every 100 standard modular bricks laid. This ratio assumes a standard 3/8-inch joint thickness and includes a typical waste allowance of 10% for dropped mortar. For blockwork, one bag of mortar typically covers about 10 to 12 standard 8-inch concrete blocks.

The most accurate bidding method uses a hybrid approach where you calculate raw material quantities by the square foot but price labor by the individual unit. Pricing labor per brick or stone allows you to adjust for different bond patterns, joints, and site complexities that a flat square-foot rate misses. This ensures your labor quote accurately reflects the physical effort and time required.

Calculate scaffolding costs by determining the total linear footage of the wall and the maximum height required, then getting a daily or weekly rental quote for the frames, planks, and safety rails. You must also calculate the labor hours required for your crew to safely erect and dismantle the scaffolding, as this often takes half a day or more on larger jobs. Always include a transport fee if you are hauling the heavy staging equipment to the site yourself.
