New-Build Snagging: What to Check Before You Sign Off
A brand-new home is not a defect-free home. A proper snag list gets problems fixed while the builder is still responsible.

New homes are built quickly, often by many different subcontractors. Minor defects are almost universal, and some are significant.
Inspecting the home carefully before completion, or within the warranty window, gives you the best chance of getting things fixed at no cost.
When to inspect
Ideally, inspect before you complete or take possession. If that is not possible, do it as soon as you move in and submit the list in writing. Check your warranty terms for deadlines on reporting defects.
Inside the house
- Doors and windows that stick, do not latch, or have gaps
- Cracks in plaster or drywall, nail pops, and uneven paint
- Tiles that are cracked, hollow-sounding, or poorly grouted
- Taps, showers, and toilets that drip or drain slowly
- Every light switch and socket working, and the electrical panel labelled
Outside and in the roof space
Look for missing or damaged roof tiles, gaps in mortar, poorly fitted flashing, and gutters that do not slope toward downspouts. In the loft or attic, check that insulation is evenly laid and that there are no signs of daylight or damp.
Consider a professional inspector
A professional snagging inspector or home inspector typically finds far more than a buyer would. They know where builders commonly cut corners and can produce a detailed report the builder is more likely to take seriously.
Follow up in writing
Keep all communication with the builder in writing, with photos of each defect. Track what has been fixed and what has not. If the builder does not respond, check your warranty provider’s dispute process.
