The deficiency list app for builders and contractors in Canada
Called a punch list in the US. Same job: walk it, write it down, get it fixed. Walkthru does just that.
How a deficiency list works in Walkthru
- Walk room by room. Rooms are preloaded in walking order; rename them to suit how you build (e.g. Mudroom, Ensuite, Basement, Cold room).
- Tap the trade. 25 trades with the common defects under each. Tell it once who your painter or tiler is and every item goes to them.
- Snap a photo or say it. "Ensuite, tiler, grout cracked at the niche" fills it in.
- Send each trade their list. A link by text or email. No login, no app to install.
- Close it out. Trades mark items fixed; you check and tick them off. Export through the API any time.
Why builders switch to it
- Faster than a spreadsheet, a notes app or a clipboard, and far lighter than full construction management software.
- Per-company pricing: add every site manager, supervisor and admin for one price.
- Works offline in basements, on rural sites and inside steel and concrete.
- Connects to Claude, ChatGPT and other AI assistants through MCP, so you can dictate a whole walkthrough.
