Collecting the keys to your new BTO flat is an exciting milestone. Before choosing paint colours, planning your carpentry, or meeting your interior designer, there's one important task you shouldn't skip—conducting a thorough defects inspection.
A proper BTO defects check helps identify issues that may have occurred during construction, allowing them to be rectified before renovation begins. Taking the time to inspect your flat now can save you from unnecessary delays, additional repair costs, and disputes later in the renovation process.
In this guide, we'll explain what to check, how to document defects, and why every homeowner should complete a defects inspection before starting their renovation.
Why Is a BTO Defects Inspection Important?
Every newly completed HDB flat comes with a Defects Liability Period (DLP), which allows homeowners to report workmanship-related defects after collecting their keys. Reporting defects early—before renovation starts—makes it much easier to determine responsibility for repairs and prevents newly completed renovation works from being affected.
A proper inspection can help you:
Identify construction defects before renovation.
Avoid paying for repairs that should be covered.
Prevent delays during your renovation.
Ensure your interior designer starts work on a defect-free unit.
Protect the quality of your finished home.
When Should You Carry Out the Inspection?
The best time to inspect your flat is immediately after key collection and before any renovation work begins.
Once hacking, painting, carpentry, or electrical works start, it becomes much harder to determine whether a defect was part of the original construction or caused during renovation.
Early reporting also gives sufficient time for rectification before your renovation schedule begins.
What Should You Bring?
A few simple tools can make your inspection much easier. Prepare:
Floor plan
Mobile phone for photos
Masking tape or painter's tape
Marker pen
Measuring tape
Spirit level
Marble or small ball (to check floor level)
Torchlight
Notebook or digital checklist
Taking clear photographs together with written notes makes future follow-ups much easier.
1. Check Every Door
Open and close every door several times. Look out for:
Doors that stick or scrape.
Loose handles.
Faulty locks.
Misaligned door frames.
Uneven gaps around the door.
Sliding doors that do not glide smoothly.
Every door should close properly without excessive force.
2. Inspect Windows Carefully
Windows are frequently overlooked during inspections. Check:
Window locks.
Hinges.
Sliding tracks.
Rubber seals.
Glass panels for scratches or cracks.
Smooth opening and closing.
If possible, inspect the windows during or after rainfall to look for signs of water leakage.
3. Examine Walls and Ceilings
Walk through every room and inspect all wall and ceiling surfaces. Look for:
Hairline cracks.
Uneven plaster.
Peeling paint.
Water stains.
Damp patches.
Paint bubbles.
Surface dents.
Use natural daylight whenever possible, as imperfections are often easier to spot.
4. Inspect Floor Tiles
Flooring deserves extra attention because repairs become more difficult once built-in furniture is installed. Check for:
Hollow tiles.
Cracked tiles.
Chipped edges.
Uneven grout lines.
Scratches.
Lippage (one tile sitting higher than another).
Rolling a marble or small ball across the floor can help reveal uneven surfaces or poor gradients.
5. Test Every Electrical Point
Before renovation starts, verify that all electrical fittings are functioning properly. Test:
Light switches.
Electrical sockets.
Doorbell.
Data points.
TV points.
Distribution board.
If any power points appear loose or faulty, record them for rectification.
6. Check Plumbing and Water Supply
Bathrooms and kitchens should be inspected thoroughly. Turn on every tap and observe:
Water pressure.
Hot and cold water supply (where applicable).
Leakage beneath sinks.
Floor traps.
Toilet flushing.
Basin drainage.
Slow drainage or standing water may indicate poor floor gradients or drainage issues.
7. Test Waterproofing
Bathrooms should drain efficiently without water collecting in one area. During inspection:
Run water across the shower area.
Observe whether water flows naturally towards the floor trap.
Look for ponding.
Check for leakage around pipes.
Proper waterproofing helps prevent future maintenance problems.
8. Inspect Kitchen Fixtures
Even if you plan to renovate the kitchen, it's worth checking the existing fittings. Inspect:
Sink alignment.
Water leakage.
Window condition.
Floor tiles.
Walls.
Existing cabinetry (if provided).
Some issues may affect renovation planning later.
9. Check the Balcony and Service Yard
Outdoor areas are exposed to weather and should not be overlooked. Inspect:
Floor gradients.
Drainage.
Ceiling condition.
Windows.
Pipes.
Railings.
Waterproofing.
Standing water after rain should be reported immediately.
10. Don't Forget the Small Details
Some of the most commonly missed defects include:
Letterbox keys.
Door stoppers.
Floor traps.
Ventilation grilles.
Air-conditioner ledges.
Utility room.
Bomb shelter door.
Exposed pipe finishes.
Take your time and inspect every corner of the flat.
How to Record Defects Properly
When you discover a defect:
Mark the location using masking tape.
Take several photographs from different angles.
Record the room and exact location.
Write a brief description of the issue.
Group similar defects together for easier submission.
Well-organised records make the rectification process much smoother.
Common Defects Found in New BTO Flats
Some of the issues homeowners frequently encounter include:
Hollow floor tiles.
Chipped tiles.
Uneven flooring.
Paint imperfections.
Misaligned doors.
Scratched window glass.
Water ponding.
Loose electrical switches.
Leaking pipes.
Hairline wall cracks.
Faulty locks.
Poor silicone finishing.
Most are minor workmanship issues but should still be addressed before renovation begins.
Should You Hire a Professional Defect Inspection Company?
Many homeowners choose to inspect their flats themselves, while others engage professional defect inspectors for additional peace of mind.
A professional inspection may be worthwhile if:
This is your first home.
You are unfamiliar with construction defects.
You want a detailed technical report.
You prefer expert guidance before renovation.
Regardless of who performs the inspection, identifying issues before renovation is the most important step.
Frequently Asked Questions
How soon should I inspect my BTO after collecting my keys?
As soon as possible. Completing the inspection before renovation begins gives sufficient time for rectification and reduces the risk of delays.
Can I renovate before reporting defects?
It's generally advisable to report and resolve construction-related defects first. Once renovation starts, it may become more difficult to determine whether an issue originated from the original construction or the renovation works.
What are the most common BTO defects?
Common findings include hollow tiles, uneven flooring, paint defects, leaking pipes, faulty doors, scratched windows, and poor silicone finishing.
Do all BTO flats have defects?
Not necessarily. While many new flats have minor cosmetic or workmanship issues, most can be rectified through the proper reporting process during the Defects Liability Period.
