How to Price Labour in a Painting Quote Without Guessing

Labour is usually one of the biggest cost drivers in a painting job, but many quotes still start with a rough day rate, a square-metre figure or a number that simply feels about right. That can work on easy jobs. It becomes dangerous when preparation, access, staging, supervision or programme pressure changes.

A better approach is to separate labour quantity from labour cost, then test the result against the margin the job needs to produce.

1. Estimate the hours before you price the dollars

Start by estimating the actual hours required to deliver the scope. Break the job into meaningful activities rather than trying to guess the whole project in one number.

• site setup, protection and masking
• washing, scraping, sanding and preparation
• repairs and patching
• priming or sealing
• each finish coat
• access setup and movement
• staging, supervision and handover
• touch-ups, cleanup and demobilisation

On a straightforward repaint, some of these may be small. On a difficult-access or remediation-heavy job, they can be the difference between profit and loss.

2. Use loaded labour cost, not just the wage rate

If an employee costs $35 per hour in wages, the business does not necessarily incur only $35 per hour. Depending on the employment arrangement, there may also be superannuation, workers compensation, leave, payroll-related costs and other employment overheads.

Your estimating system should use a deliberate loaded labour cost that reflects the cost basis your business has chosen. Do the same for subcontract labour: use the actual rate the subcontractor will cost the job, not the rate you hope to negotiate later.

3. Calculate labour cost by job

The basic calculation is simple:

Estimated labour hours × loaded labour cost per hour = estimated labour cost.

If you estimate 160 hours at a loaded cost of $55 per hour, estimated employee labour cost is $8,800.

That is a cost input. It is not automatically the selling price for the labour.

4. Add the other direct costs

A painting quote should also account for materials, plant, access equipment, subcontractors and other direct job costs. Once those are assembled, you can see the estimated direct cost of delivering the work.

At this point, many contractors make a common mistake: they simply add a markup and send the quote. That can hide whether the final gross margin is actually acceptable.

5. Test the whole job against gross margin

Gross profit is:

Selling price − job cost = gross profit.

Gross margin percentage is:

Gross profit ÷ selling price × 100.

If a $20,000 job has an estimated job cost of $14,000, gross profit is $6,000 and gross margin is 30%.

The important point is that margin should be tested on the complete job, not on labour in isolation.

6. Stress-test the labour assumption

Before sending the quote, ask what happens if the labour estimate is wrong.

• What if preparation takes 20% longer?
• What if access slows production?
• What if the substrate condition is worse than visible at inspection?
• What if the programme requires extra mobilisation or staging?
• What if colour changes or additional coats are required?

If a modest labour overrun destroys the job margin, the quote may be too fragile.

7. Make the labour assumption visible

A strong estimating process does not rely on memory. Record the hours, rate basis and important assumptions in the estimate so someone else can review them before the quote is issued.

That review is especially useful when the estimator is also the owner, because it creates a deliberate pause between building the number and sending it.

A useful final check

Before issuing a painting quote, check labour alongside scope, preparation, access, direct costs, exclusions and variation exposure. Our 20-point painting estimate checklist gives you a quick pre-send review.
