Resale HDB: The Renovation Reality
Buying a resale HDB is one of the most common paths to homeownership in Singapore — and for good reason. You get a unit in an established neighbourhood, often with a mature estate, good transport links, and no Minimum Occupation Period before you can rent out a room. But unlike a BTO where everything starts fresh, a resale flat comes with a history. Some of it shows up on inspection day. Some of it only surfaces after you’ve moved in.
Before you call a contractor, here’s what to actually assess and prioritise.
Step 1: Inspection Before You Commit
If you haven’t yet signed the OTP (Option to Purchase), do a thorough inspection with fresh eyes. Bring a torch. Check these specifically:
- Waterproofing in bathrooms: Look for staining, efflorescence (white mineral deposits), or hollow-sounding tiles near the floor edges. These point to waterproofing failure that will need full hacking.
- Ceiling stains: Brown or yellow ceiling stains indicate previous water seepage — from above or from your own bathrooms. Find out if they’ve been resolved or if they’re ongoing.
- Wall cracks: Hairline cracks are normal and cosmetic. Wide or diagonal cracks, especially around door frames and window frames, warrant further investigation.
- Electrical switchboard: Open the DB box and check whether there are older-style fuses or modern circuit breakers. Older wiring (especially aluminium rather than copper) is a red flag for a resale flat.
- Plumbing: Turn on all taps simultaneously. Low water pressure across multiple points suggests pipe issues. Check under sinks for rust or previous leaks.
- Ventilation: In older HDB flats, the kitchen and bathrooms may have inadequate exhaust ventilation. This affects air quality and mould risk.
Step 2: The Non-Negotiable Fixes
Some things in a resale renovation are optional (a kitchen facelift, new flooring, fresh paint). Others aren’t really optional if you’re going to live there comfortably and safely:
- Bathroom waterproofing: If the existing waterproofing is more than 10–15 years old or showing any signs of failure, hack and redo it. There is no shortcut here. A bathroom renovation without addressing waterproofing first is money poorly spent — you’re covering up a problem that will resurface. Our tiling and waterproofing team does this properly.
- Electrical rewiring: For flats more than 20–25 years old with aluminium wiring or outdated switchboards, full rewiring is strongly recommended. The cost is real but the alternative — electrical fires and repeatedly tripped circuits — is far worse. Our electrical works guide explains the scope involved.
- Plumbing inspection and upgrade: Galvanised iron pipes in older HDB flats corrode from the inside and reduce water quality over time. If your resale flat has old galvanised pipes, replacing them during renovation — before tiling goes in — is the right call. Doing it after tiling means hacking and retiling.
Step 3: What’s Worth Upgrading vs. What Can Wait
Not everything needs to be done before you move in. Here’s how to think about prioritising:
Do before moving in: Wet works (waterproofing, hacking, tiling), electrical works, plumbing, painting, flooring. These are disruptive enough that living through them is genuinely unpleasant.
Can be phased in later: Carpentry (unless it’s replacing functional but ugly existing furniture), kitchen cabinet refacing, new light fittings, curtains and blinds. These are less disruptive and easier to handle room by room while you’re living in the flat.
If budget is tight, prioritise the structural and systems work now and build out the aesthetics over the next 12–24 months. Living without perfect carpentry is manageable. Living with failing waterproofing is not.
