how to price a job you haven't done before

Someone asks you to do something you have never bid. Maybe it is a basement finishing and you have only done additions. Maybe a client wants polished concrete floors and you have always laid tile. The job is within your skill set — just outside your experience.

You have two options. Say no and watch the work go to someone else. Or figure out what it actually costs, price it honestly, and add a new service to your business. This guide is about option two.

step one: get real material numbers

Do not Google "average cost of polished concrete per sqft" and use that. Those numbers are stale, vague, and usually wrong. Instead, pick up the phone.

Call two or three suppliers. Tell them what you need. Get actual quotes for the actual materials on the actual job. A supplier quote in writing is a Certain tier line item. A number you pulled from a blog post is a Wild Guess. That difference matters when you run the simulation.

Ask suppliers about lead times too. A specialty product that takes six weeks to arrive changes your schedule and your costs.

step two: talk to someone who has done it

You know other contractors. Ask one who has done this type of work before. Not for their exact prices — just for the things you do not know to ask about. Hidden costs. Common problems. Things that catch first-timers out.

A twenty-minute conversation can save you thousands. Most contractors will help if you ask honestly. "I have not done one of these before, what should I watch out for?" goes a long way.

step three: be honest about your uncertainty

This is where most people go wrong. They have never done the job before but they mark every line item as Low uncertainty because they do not want to face the real numbers.

If you have not done this work before, most of your line items are High or Wild Guess. That is not a problem. That is just reality. The tool is designed to handle it — it will widen the range and give you a bid that accounts for the unknowns.

The only person you hurt by lying about uncertainty is yourself. Mark things honestly and let the math do the work.

step four: build in learning time

You will be slower on the first one. That is normal. A tile contractor doing their first polished concrete job will take longer than someone who has done fifty. Price your labor accordingly.

Add 20-30% more time than you think a seasoned pro would take. Put it in as a separate line item — "additional labor (first project of this type)" — so you can see exactly what the learning tax costs you. On the next job, you will drop that line entirely.

when to walk away

Sometimes the honest answer is: this is not the right job to learn on. Walk away if:

• The client wants a fixed price and will not accept any change orders.
• The job is high-value and you cannot afford to get it wrong.
• You cannot find a single person to ask for advice.
• The simulation output shows a massive spread between P50 and P95 — that means your uncertainty is so high that no reasonable bid will protect you.

There is no shame in saying "this is not my area." Refer it to someone who does it regularly. They might return the favor when something in your wheelhouse comes up.

worked example: bidding your first basement finishing job

You are a general contractor. A client wants their unfinished basement turned into a living space — framing, insulation, drywall, flooring, and a half bath. You have done plenty of drywall but never framed a basement from scratch. Here is how you might price it:

Notice the split. The materials are low-risk because you got real prices. The drywall labor is low-risk because it is your core skill. But the framing labor is High because you have never done it. That honesty is what makes the bid safe.

Base estimate: $9,650. After simulation, your P80 might come in around $10,850. That extra $1,200 is not padding — it is the cost of doing something new, calculated properly.
