What it is
Pre-renovation termite treatment is an inspection, and treatment if needed, done before new carpentry, flooring and built-ins go in. The aim is to deal with existing activity and protect the areas that will soon be covered up, when they're still easy to reach.
For landed rebuilds and major extensions, the equivalent is pre-construction soil treatment, applied to the ground before the new slab is cast.
Why timing matters
- Once cabinets, wardrobes and flooring are installed, the walls and floor behind them are hard to inspect or treat.
- Hacking and removing old carpentry can disturb an existing colony and expose activity you didn't know about.
- Termites found in brand-new carpentry are more expensive to deal with than termites found in an empty room.
BTO, resale and landed homes
- New BTO flats: a new flat isn't automatically termite-free, especially in estates built near greenery. If you find activity in HDB-supplied fittings within the one-year defect liability period, report it to HDB (HDB, Rectification of Defects in New Flats). For your own carpentry, a pre-renovation check is a sensible precaution.
- Resale flats: old carpentry is coming out anyway, so this is the best chance to see what's behind it. Ask the operator to inspect once hacking is done.
- Landed homes: ask about soil treatment or baiting around the house, and about the roof space if it has timber trusses. Pre-construction soil treatment is quoted by floor area.
When to schedule it
- Book an inspection before work starts, to spot any existing activity.
- Do treatment after hacking and removal, before carpentry, flooring and built-ins are installed.
- Agree the date with your renovation contractor or interior designer, so it isn't skipped when schedules move.
- Keep the treatment report and warranty with your renovation documents.

Questions to ask
- What exactly will be treated: walls, floor, the areas where carpentry will go?
- Which method, and is it suitable once flooring is laid over it?
- Is there a warranty, and does it still apply after the renovation is finished?
- Do you need the space empty, and for how long?
- Is the company registered with NEA? You can check on NEA's list.
Pre-renovation treatment reduces risk but doesn't guarantee termites will never appear. Keep an eye out for the usual signs after you move in.
Questions
Do new BTO flats need termite treatment?
Not always, but new flats aren't automatically termite-free. A pre-renovation inspection before carpentry goes in is a low-cost precaution. If you find activity in HDB-supplied fittings within the first year, report it to HDB.
When should termite treatment happen during renovation?
After hacking and removal of old fittings, and before new carpentry, flooring and built-ins are installed. Agree the date with your contractor in advance.
How much does pre-renovation termite treatment cost?
KakiList lists pre-renovation termite inspection and treatment at S$200–400. Landed new builds use pre-construction soil treatment, which Rentokil lists from S$900, based on floor area. These are indicative, not quotes.
