The snagging list app for housebuilders and contractors in the UK and Ireland

Called a punch list in the US. Same job: walk it, write it down, get it fixed. Walkthru does just that.

Updated October 2026, by the Walkthru team in Nashville

In short: Walkthru is a snagging list app built for the person walking the property with a phone. Pick the room, tap the trade, tap or say the defect, done. Each trade gets a link to their own items with photos and taps Mark fixed when it's done. It works with no signal and it's free for one job; Pro is billed per company, not per user.

How a snagging list works in Walkthru

  1. Walk room by room. Rooms are preloaded in walking order; rename them to suit how you build (e.g. Ensuite, Utility, Boot room, Snug).
  2. 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.
  3. Snap a photo or say it. "Ensuite, tiler, grout cracked at the niche" fills it in.
  4. Send each trade their list. A link by text or email. No login, no app to install.
  5. Close it out. Trades mark items fixed; you check and tick them off. Export through the API any time.
