What it is
ChatGPT is OpenAI's general-purpose AI assistant. You type a request, or upload files and images, and it writes, answers questions, analyzes what you gave it, creates images and helps with code. Contractors in this directory use it to draft scopes of work, proposals and invoices, write pricing formulas and make concept renderings, and some build custom GPTs on their own documents.

Use cases with ChatGPT (5)
Build a custom GPT that writes code-compliant roof repair estimates from a voice prompt
Leakbusters Roofing
Owner Richie Kleti's team built a custom GPT, tied to historical job data and manufacturer specs, that turns a short voice prompt into an itemized, code-compliant Florida repair estimate. New hires can produce accurate estimates without waiting for senior staff to price every job. The team also uses an AI sales coach in role-play "sales cage match" sessions, where reps are mic'd up and get feedback on tone, objection handling and what to do better.
Give plumbers ChatGPT on a tablet for proposals, invoices and troubleshooting
Oak Creek Plumbing & Remodeling
The roughly 20 plumbers at Oak Creek Plumbing & Remodeling near Milwaukee carry tablets with ChatGPT. They photograph a broken water heater or type up what they see, and use it to draft work proposals and invoices and to brainstorm fixes for tricky problems. President Dan Callies told CNN that even older techs have learned to ask it the right questions and that it has helped the company "lower our overhead and provide better services or better value."
Train ChatGPT on past scopes to write kitchen & bath SOWs
Jimmy McKinney (remodeler)
Remodeler Jimmy McKinney subscribed to OpenAI's service and trained his own version of ChatGPT on his company's past scopes of work for kitchen and bath projects. He gives it a written or spoken prompt about a new job and gets a draft SOW quickly, built on his own templates. Qualified Remodeler's editor says this one shortcut is already making the company more efficient.
Have ChatGPT write cost formulas for your estimating software
Trevor Young (remodeler, JobTread user)
Remodeler Trevor Young uses ChatGPT to write pricing formulas inside JobTread, such as one for pricing dirt haul-off. He first had to teach it how JobTread's formula logic differs from Excel. Now he gives it the context, parameters and output he needs, and it returns formulas that fit his setup, saving hours of spreadsheet work. The video's advice: always double-check the math.
Mock up a porch addition from a phone photo to move a sale forward
Remodelers in the JobTread community
A remodeler named Jim photographed a client's house and had ChatGPT produce a concept image of it with a new front porch, which took about a minute and helped move the client toward a design agreement. Others use it to straighten room photos and remove clutter. The video warns that AI images can change details such as logos or move objects, so they're for early concept conversations, not portfolio shots or final designs.
