Mason Gang Leader job description
A Mason Gang Leader heads a team of masons and helpers on a building site. They lay out the work, keep the quality up and make sure the gang finishes what the engineer has planned.
Why the role exists
The gang leader is a skilled mason who also leads a crew. On Indian building sites, the gang often comes through a labour contractor, and the leader links the foreman's instructions with the men doing brickwork, blockwork, plaster and the finishing stages that follow.
What the person does
- Take the day's work instructions from the foreman and explain them to each mason and helper in the gang.
- Set out brickwork and blockwork lines using thread, plumb bob and level before the gang starts laying.
- Lay and check courses, joints and corners yourself on key sections to set the quality standard for the gang.
- Prepare the mortar and plaster mix ratios as instructed, and make sure the helpers mix and carry them correctly.
- Count the work done each day, such as area plastered or blocks laid, and report it to the foreman.
- Check that the gang uses scaffolds, ladders and personal protective equipment correctly.
- Redo or correct faulty work found at the engineer's inspection without delay.
- Keep the gang's attendance, break times and wage claims clear and report disputes to the foreman or labour contractor.
Skills and tools
- Brickwork, blockwork and plaster practice
- Setting out with thread, plumb bob, spirit level and measuring tape
- Mixing mortar and plaster to the ratios given
- Leading and training a gang of masons and helpers
- Estimating quantity of work done in a day
- Safe working on scaffolds and ladders

- Clear instructions in the local language to a mixed crew
Education and experience
Preferred, never a bar: equivalent experience counts.
- Preferred: many years as a working mason, including time leading a smaller crew, or equivalent experience.
- Preferred: trade training from an ITI or a skills programme, though not required if skill is proven.
- Preferred: ability to read simple measurements and sketches given by the engineer.
- Preferred: knowledge of safe work on scaffolds, with any training confirmed with the employer's adviser.
How the work is judged
- Quality of masonry at the engineer's inspection and amount of rework.
- Output of the gang against the work allotted for the day.
- Wastage of mortar, bricks and blocks used by the gang.
- Gang attendance and how steady the team stays across the project.
- Safe working practice seen in the gang on each shift.
Where the role can lead
- Site Foreman or Site Supervisor over several gangs.
- Labour contractor or sub-contractor with own crews.
- Trainer for masonry and finishing trades.
Interview questions to ask
Ask every candidate the same questions in the same order and score them against written anchors, so the decision rests on the work and not the impression.
- How do you check that a wall is plumb and in line before the mortar sets?
- Your gang falls behind. How do you recover the day's work without cutting quality?
- Tell us how you train a new helper to become a mason.
- The engineer rejects a section you built. What do you do?
- How do you manage two masons who do not get along?
- Describe how you protect your gang when working at height.
Hiring tips for this role
- Test the trade directly. Ask the candidate to lay a short wall or plaster a patch on a live site. Interview talk does not show hand skill.
- Check the size of the gang led before. Leading four men is not the same as leading twenty.
- Be clear about who employs the gang, you or a labour contractor, and who pays them. Confusion here causes walkouts.
- Use a trial day where possible and agree the stay, travel and meal arrangements in advance.
Questions about hiring a mason gang leader
They lead a team of masons and helpers on site, set out and check masonry, and answer to the foreman for output and quality. They are also hands-on with the work.
Often, yes. Different regions use different terms such as head mason, mistri or crew leader. The job description should say clearly the size of the gang and the scope of the work.
No. Proven skill and leading experience matter more. A trade certificate can help, but your job description should accept equivalent experience.
