FAQ
Does it know plumbing materials and fixtures?
Yes. WonTheJob understands Kohler, Moen, Delta, Rheem, Rinnai, Bradford White, and other major plumbing brands. It knows the difference between tankless and tank water heaters, PEX-A vs. PEX-B, and will include specific product and material references based on what you tell it about the job.
Can I use it for service calls and larger remodels?
Yes — both. For a quick service call like a water heater swap or PRV replacement, use Concise Mode to generate a short, clean proposal in seconds. For a full repipe or bathroom rough-in, use Standard Mode for a detailed scope, materials list, timeline, and warranty section.
Does it work on my phone on a job site?
That's exactly what it's built for. Open WonTheJob while you're still under the sink or in the crawl space. Use voice input to describe what you found and what needs to be done. A complete proposal is ready by the time you're back at your truck. The homeowner can approve it before you drive away.
