Defect library
Doors & joinery defects in new builds
Doors and joinery make up one of the biggest categories in the library because every room has them and each one can catch, rub or fail to latch. Fire doors, balustrades and stair headroom sit here too, and those are safety items to report in their own right.
Updated 19 October 2026
SiteSnag’s library has 38 entries under doors & joinery, and 7 of them are marked as safety or critical items. They’re listed below with the most serious first. Each one gives the wording an inspector would put in a report and the trade that would fix it, and 29 carry a reference to the standard or guidance they relate to. The references help you look up the relevant section and aren’t a statement that a particular home does or doesn’t comply.

Using these in a report
In the SiteSnag app, starting to type a defect title in the camera brings up these entries. Picking one fills in the description, severity, trade and reference, and you can edit the wording or add your own defects to the library. Every snag then goes into the branded PDF report with its photos and a numbered pin on the floor plan.
For a room-by-room walk-round, use the new build snagging checklist, or go back to all defect categories.
