ProTradesmanBuilt for the jobsite, not the office

Pass inspection the first time. Every time.

One failed inspection costs you a return trip, a reinspection fee, and a day of schedule. Ask ProTradesman in plain English, or snap a photo of the panel and ask “is this right?” You get the code-backed answer before the inspector ever shows up.

9 trades, each with its own code book. Jurisdiction notes for your state.

1 in 4

First-time inspections that fail in a typical jurisdiction. One of America's largest code authorities saw pass rates as low as 55 percent before it started billing contractors by their failure rate.[1][2][3][4]

2-20%

Of contract value lost to rework. Roughly half of rework traces to bad data and miscommunication at install time.[5]

5 for 2

Five pros retire for every two who enter. The guy you used to ask isn't on the jobsite anymore. We are.[6]

See it in action

Ask it, or show it.

Snap a photo of the panel, the rough-in, the roof, and ask “is this right?” You get a code-cited answer and a real reference photo back. When something’s unclear, it asks before it answers, the way a good foreman would.

Three taps between you and the right answer.

No menus to dig through. No forum threads to wade through. Question to code-cited answer in seconds.

01

Pick your trade

Your code book, your parts vocabulary, your context. Nothing generic.

02

Ask it, or show it

Type it like you'd say it: "Can I land two grounds under one lug?" Or snap a photo of the panel, the rough-in, the roof, and ask "is this right?" Plain English or a field photo in, straight answer out.

03

Get the answer plus the picture

A code-cited answer streams in. A real reference photo lands under it. Show the inspector. Show the homeowner. Move on.

What that's worth on a real job.

The math is not subtle. One avoided mistake covers the cost many times over.

Never lose the day to a red tag.

Fail an inspection and the meter starts. You fix it, re-request, and wait for the next slot. Many jurisdictions give no time window at all, and Colorado's state board requires you or your rep on site for occupied homes, so someone stands around while the schedule slips. Contractors in Charlotte pay $230 blocks just to pin an inspector to a time. The reinspection fee itself ($25 to $75 in most jurisdictions, more in some) is the cheapest part of failing. Check the code call before you close the wall, and the day stays yours.[7][8][9][10][11][12]

Kill callbacks before they happen.

Rework runs 2 to 20 percent of contract value, and about half of it comes from bad information at the moment of install. The answer that prevents the callback costs you ten seconds, not a truck roll.[5]

Get journeyman-smart years faster.

The gap between apprentice pay and journeyman pay is $25K or more a year per BLS wage data. Every question you get answered on the job, with the code section to back it up, closes that gap faster. Stop waiting for someone to have time to teach you.

The 30-year master in your pocket.

The trades are losing experience faster than they can replace it. Five pros retire for every two who start. The foreman who knew every code section, every part number, every inspector’s pet peeve, he’s retiring, and nobody downloaded his brain. ProTradesman is the closest thing: tight, technical, code-first answers, on demand, on the jobsite, for less than the cost of one coffee a week.

Common questions

Will this actually help me pass inspections?
That's the whole point. Answers are code-first and cite the section, so you can verify before the inspector arrives and show your work if he pushes back. When the model isn't sure, it says so up front instead of guessing.
Is this for licensed pros only?
Anyone can ask, but answers are written for working tradespeople: tight, technical, code-first. Apprentices use it to get journeyman-smart faster. Homeowners may find the hand-holding they expect missing.
Where do the answers come from?
Every question routes through the strongest frontier reasoning model available at the time, locked to your trade and required to know NEC, IPC, UPC, IFGC, IRC, IBC, IMC, and IECC. Reference images come from a curated library of 1,500+ trade photos, or get generated on demand when no match exists. As the frontier moves, we move with it.
Can I trust the code citations?
The model only cites sections it's confident about. When it's not sure, it tells you, so you never stake an inspection on a guess.
What about local amendments?
We surface state and jurisdiction notes when they'd materially change the answer. Local amendments override base code in a lot of places, and that's exactly where red tags come from.
How much does it cost?
Less than one reinspection fee. Plans start at $9 a month for Apprentice. Annual saves 15 percent. Cancel anytime.
What if it's not for me?
Cancel anytime, no questions. And if you're inside your first 7 days on a new subscription, email support and we refund your first invoice in full, monthly or annual. Refunds land back on your card in 5 to 10 business days.

One red tag costs more than a year of this app.
