Snagging checklist: how to inspect a new builder floor

Before you take possession, walk the floor with this checklist to catch defects while the builder is still on site.

"Snagging" means finding and listing defects before you take possession. A careful inspection now saves expensive repairs later.

Bring with you

A torch, a spirit level, a phone charger (to test sockets), a bucket of water, masking tape to mark defects, and a copy of the specification schedule.

Walls, floors and ceilings

• Hollow-sounding marble tiles (tap gently with a coin)
• Uneven floors, chipped edges, lippage between slabs
• Cracks, damp patches or bubbling paint, especially near windows and bathrooms

Bathrooms and kitchen

• Pour water: does it drain quickly, with the slope towards the drain?
• Check under sinks for leaks
• Test every tap and flush, hot and cold

Electricals

• Test every switch and socket
• Check the distribution board is labelled and has RCCB protection
• Verify the inverter or power-backup changeover

Doors, windows and fittings

• Doors and windows close smoothly and seal properly
• Wardrobes and kitchen cabinets are aligned and hinges are tight

Terrace and basement

• Look for seepage marks
• For terraces, check slope and drainage outlets

After the walk-through

Give the builder a written, dated list. Agree a timeline for fixes and keep a portion of the final payment until they are completed, if the agreement allows.

Lifts and common areas

• Check that the lift has a valid licence and an annual maintenance contract
• Test the emergency alarm and backup power for the lift
• Inspect stilt lighting, drainage and the condition of the parking area

Water and plumbing

• Check water pressure on your floor at different times of day
• Confirm the capacity of the underground and overhead tanks
• Find out whether there is a booster pump and who maintains it

Air-conditioning

Run every unit for at least ten minutes. Check that drains don't leak onto balconies or walls and that the outdoor units are safely mounted.

Paperwork at handover

• Warranty cards for appliances, air-conditioners and lifts
• As-built drawings showing pipe and wiring routes
• Contact details for the builder's after-sales team

When to bring a professional

For large purchases, an independent home inspector or civil engineer can spot defects that untrained eyes miss, especially in waterproofing and electricals.

Frequently asked questions

What if the builder doesn't fix defects? Withhold a reasonable part of the final payment, if your agreement allows it, until the agreed fixes are done.
