Bottom line up front: across the Singapore market, professional formaldehyde and VOC removal is usually priced per square foot or per treatment, typically from around S$1.50 to S$4 psf, with most HDB and condo homes landing between S$300 and S$900 for a full treatment. The number moves with floor area, how many treatment passes are needed, and whether an air-quality reading is included before and after.

TL;DR
- Formaldehyde removal in Singapore is priced per square foot or per treatment, tied mainly to floor area.
- Typical market range: S$1.50–S$4 psf; most HDB and condo homes land S$300–S$900.
- The treatment breaks down formaldehyde and VOCs off-gassing from new carpentry, adhesives and paint — it does not just mask the smell.
- It is most worth it right after a renovation and for homes with children, elderly, or anyone with respiratory sensitivity.
- Confirm whether a before-and-after air-quality reading is included, as it affects both value and price.
What formaldehyde removal actually is
New homes have a hidden problem after renovation: the materials themselves release gas. Formaldehyde and other volatile organic compounds, or VOCs, off-gas from new carpentry, wardrobes, adhesives, laminates and fresh paint. That is the sharp chemical smell in a newly renovated unit.
Formaldehyde removal — also called VOC removal or air-purifying treatment — breaks those compounds down rather than covering them. A crew applies a treatment agent to the surfaces that off-gas the most, often carpentry and cabinetry, usually with a catalyst that helps neutralise the compounds. The aim is to bring the level down quickly instead of waiting out the months it would take on its own.
For the background on why this matters and what the health effects are, see our guide on whether formaldehyde is dangerous after a renovation.
What drives the price
1. Floor area
More square footage means more surfaces to treat, so the price scales with area — the same logic as most cleaning and restoration work.
2. Number of treatment passes
A single treatment lowers the level; heavily off-gassing homes, or homes where the reading is still high afterward, may need a second pass. More passes mean more time and material.
3. Whether air-quality readings are included
Some services measure formaldehyde or total VOC levels before and after so you can see the change. That reading adds value and cost. A treatment quoted without it will be cheaper but gives you no number to judge the result by.
4. Amount of carpentry in the home
A home full of new built-in wardrobes, feature walls and cabinetry off-gasses more than one with mostly loose furniture. The more new carpentry, the more surface there is to treat.
Formaldehyde removal price ranges
The table below gives typical Singapore market ranges so you can sanity-check any quote. These are general market figures across providers and are not OCD's prices.
| Home type and size | Full treatment (typical market range) |
|---|---|
| HDB 2- to 3-room | S$250 – S$500 |
| HDB 4- to 5-room | S$400 – S$750 |
| Condo (1 – 2 bedroom) | S$350 – S$700 |
| Condo (3+ bedroom) / landed | S$700 – S$1,500+ |
Ranges reflect the broad Singapore market as a guide only. They are not a quote from OCD, and actual pricing varies by floor area, amount of carpentry, and whether readings are included. The accurate figure for your home is the one quoted on your specific details.
Is it worth it? An honest answer
Formaldehyde removal is not something every home needs, and it is worth being straight about when it earns its cost.
It is most worth it right after a renovation, when off-gassing is at its highest, and for homes with young children, elderly family, or anyone with respiratory sensitivity. It also helps when you need to move in soon and cannot leave the home ventilating for weeks.
If your home is well ventilated, you have no sensitive occupants, and you can leave windows open for several weeks, natural airing will also lower the levels — just more slowly. Singapore's heat and humidity actually speed up off-gassing, so consistent ventilation does real work. The treatment buys you time and a faster, measured result; it is not the only way levels come down.
How to get an accurate price for your home
The ranges above tell you what is normal. The only figure that matters is the one quoted on your actual home. To get an accurate fixed price, share three things:
- Home type and size — HDB, condo, or landed, with square footage or room count.
- How recent the renovation or new furniture is.
- Whether you want an air-quality reading included before and after.
With those details, OCD quotes a fixed price up front, with no add-on charges on the day. See the full scope on our formaldehyde removal page.
