Owning an HDB flat in Singapore is a significant milestone for many, providing stability and pride. However, like any property, HDB flats have their fair share of challenges. From plumbing issues to structural concerns, new and experienced homeowners often face difficulties that can cause inconvenience and frustration.
Here, we’ll look at 10 common HDB problems homeowners encounter, their causes, and, most importantly, how to resolve them. Whether you’re a first-time homeowner or someone dealing with ongoing issues, this guide will provide valuable insights to help you maintain a comfortable living space.
1. Leaky Pipes and Water Damage
Leaky pipes are a frequent issue in many HDB flats, often resulting in water damage to your walls, flooring, and ceilings. Pipes wear down over time due to general wear and tear or poor installation, leading to cracks or breaks. HDB flats that are older are more prone to these issues. Leaks can lead to mold growth and other more significant damage when not addressed quickly.
How to Fix It:
If you spot a leak, shut off the water supply immediately to prevent further leakage. Call a licensed plumber to inspect the pipes and make necessary repairs or replacements. Regular maintenance and checks can help identify potential issues before they turn into costly repairs.
2. Poor Water Pressure
Low water pressure is a common issue faced by homeowners in Singapore. It can be caused by clogged pipes, faulty water valves, or problems with the building’s water supply system. When water pressure is low, showering, washing dishes, or filling a bathtub becomes frustrating.
How to Fix It: Start by checking if the problem affects just one faucet or the entire flat. If it’s just one fixture, cleaning the aerator might help. For widespread low water pressure, contact the building management to check the water supply or hire a plumber to inspect and clean the pipes.

3. Blocked Drains
Blocked drains are a persistent problem in many homes. Over time, food waste, grease, hair, soap scum, and other debris build up in the pipes, causing blockages that prevent water from draining correctly. Blocked drains can result in unpleasant odors and potential flooding in your home.
How to Fix It:
Minor clogs can often be cleared with a plunger or drain snake. For more serious blockages, it’s best to call a professional plumber who can use specialized tools, such as hydro-jetting, to clear the obstruction. Regularly clean your drains to prevent blockages and avoid pouring grease or food scraps down them.
4. Electrical Issues and Frequent Power Trips
Electrical problems, such as power trips or malfunctioning outlets, are common in older HDB flats. These issues can stem from faulty wiring, overloaded circuits, or outdated electrical components. Frequent power trips often happen when circuits are overloaded, or there’s a short circuit somewhere in the system.
How to Fix It: If you experience frequent power trips, avoid overloading your electrical sockets with too many devices. For ongoing electrical issues, hire a licensed electrician to inspect your system. Avoid attempting to fix electrical problems on your own, as it can be dangerous.
5. Pests and Infestation
Pests like cockroaches, ants, and termites are common issues in many HDB flats. These pests can not only cause damage to your property but also create hygiene concerns. Pests enter through cracks and gaps in the walls, windows, or doors. Poor hygiene and food waste also attract them into your home.
How to Fix It:
To prevent pests, maintain a clean home and dispose of food waste regularly. Use sealants around windows, doors, and pipes to block entry points. Call a pest control professional to eliminate the problem if an infestation occurs. Regularly inspect your home for signs of pests and address them immediately.
6. Water Seepage and Damp Walls
Water seepage is common in older HDB flats, especially during heavy rains. It occurs when water from external sources seeps through cracks in the walls and ceilings, causing dampness and water damage. This problem can worsen if the external weather conditions aren’t adequately addressed.
How to Fix It: To address water seepage, first identify the source of the issue. Seal cracks around windows, doors, and pipes to prevent further moisture from entering. If the problem concerns plumbing, contact a plumber to fix any leaking pipes. In some cases, you may need to repair the structural damage of your flat, which might require a contractor’s services.

7. Mold and Mildew
Mold and mildew growth is common in humid climates like Singapore. These fungi grow in damp areas such as bathrooms, kitchens, and laundry rooms. They thrive in poorly ventilated areas and can pose health risks, especially for those with allergies or respiratory issues.
How to Fix It: Ensure that your home is adequately ventilated, particularly in high-moisture areas. Use exhaust fans in bathrooms and kitchens to reduce humidity. If you already have mould or mildew, clean the affected areas with vinegar or hydrogen peroxide and water. For larger infestations, it’s best to consult a professional for removal.
8. Worn-Out Door and Window Seals
Old, damaged, or worn-out seals around doors and windows can cause drafts, increase energy bills, and lead to water leakage. These issues are prevalent in older HDB flats, where seals may deteriorate over time due to weather exposure.
How to Fix It: Inspect your door and window seals for cracks or wear. Replace any damaged seals with new weatherstripping or silicone sealant. This will help improve your home’s energy efficiency and prevent drafts and leaks. For better insulation, consider adding weatherproofing materials to enhance your home’s comfort.
9. Creaking Floors
Creaking floors can be a source of frustration, especially in the middle of the night. Though not a structural concern, creaking floors can disrupt your peace and cause annoyance, particularly in older flats where the foundation or floorboards may shift over time.
How to Fix It: If the creaks are isolated to specific areas, you can try tightening the nails or screws in the floorboards. If the noise persists, you may need to replace the damaged floorboards or use a lubricant, such as talcum powder, between the joints to reduce friction.

10. Faulty Aircon Units
Aircon is essential in Singapore’s humid climate. However, many HDB residents experience issues with their aircons, such as weak airflow, strange noises, or inconsistent cooling. These issues often stem from dirty filters, blocked air vents, or refrigerant problems.
How to Fix It: Regular maintenance is key to keeping your aircon running smoothly. Clean or replace the filters every few months and schedule an annual checkup with a professional technician. If the problem persists, an in-depth repair or replacement of the unit may be required. Request for professional aircon servicing with StringsSG.
