What does formaldehyde removal in Singapore involve?
Formaldehyde removal treats the source — the urea-formaldehyde resins in plywood, MDF and built-in carpentry — with decomposition agents, rather than waiting years for off-gassing to finish naturally. A professional treatment in Singapore costs S$420–1,080 by home size, takes 2–4 hours, and should always include before/after meter readings benchmarked against the WHO guideline of 0.1 mg/m³.

How a treatment visit works
Step 1
Baseline readings
We measure formaldehyde in every room with a calibrated professional meter before touching anything, so you see exactly where your home stands.
Step 2
Source treatment
Decomposition agents — including a light-activated photocatalyst — are applied to carpentry, built-ins, furniture and soft surfaces, breaking formaldehyde down where it is released.
Step 3
Post-treatment readings
The same rooms are measured again on the same visit. You leave with a written report benchmarked against the WHO 0.1 mg/m³ guideline.
Step 4
30-day guarantee
Off-gassing continues after treatment, so if any reading rises back above the guideline within 30 days, we return and re-treat free.
Why the smell outlasts the renovation
Most renovation smells — paint, adhesives, sealants — are volatile organic compounds that dissipate within weeks. Formaldehyde is different: it is bound inside the urea-formaldehyde resins that hold plywood, MDF and particleboard together, and it releases slowly as those resins break down. Studies measure meaningful off-gassing for 3 to 15 years, and Singapore's heat and humidity accelerate the release.
The IARC classifies formaldehyde as a Group 1 carcinogen, and both the WHO indoor air guideline and Singapore's SS 554 standard set the same benchmark: 0.1 mg/m³. Ventilation helps, but with the source sealed inside your carpentry, airing out alone can take years to get there — which is why source treatment, verified by readings, is the approach we use.
Just-renovated homes
New carpentry, fresh paint and that unmistakable smell — the most common booking, ideally before you move in.
Families with babies on the way
Infants and pregnant women are the groups health agencies advise to keep exposure lowest for.
New furniture, older homes
A single wardrobe, bed frame or mattress can push a bedroom above the guideline for months.
Offices and childcare centres
Commercial fit-outs off-gas the same way homes do — we treat and certify by floor area.
Below the guideline — or we come back free.
Every job ends with room-by-room readings. If any room rises back above 0.10 mg/m³ within 30 days of treatment, we return and re-treat at no charge. That is the whole guarantee — no fine print about "odour" or "satisfaction", just the number on the meter.

Common questions, straight answers
How much does formaldehyde removal cost in Singapore?
Fixed prices by home size: S$420 for homes up to 500 sqft, S$620 for a typical 4-room HDB, up to S$1,080 for landed homes to 3,000 sqft, inclusive of GST. Every job includes before/after meter readings and a free 30-day re-treatment if readings rise back above the WHO guideline. A testing-only visit is S$180, fully credited if you book removal within 30 days.
Is the formaldehyde smell after renovation dangerous?
Formaldehyde is classified as a Group 1 carcinogen by the IARC, and short-term exposure above the WHO guideline of 0.1 mg/m³ irritates the eyes, nose and throat. The smell itself is not a reliable gauge — some people stop noticing it within days while levels remain elevated. The only way to know your home is safe is to measure it.
How long does formaldehyde off-gassing last?
Unlike most renovation VOCs, which dissipate in weeks, formaldehyde is released slowly from the urea-formaldehyde resins inside plywood, MDF and particleboard — studies measure meaningful off-gassing for 3 to 15 years. Singapore’s heat and humidity accelerate the release, which raises indoor levels rather than clearing them.
Does formaldehyde removal treatment actually work?
Yes — professional treatment applies decomposition agents (including photocatalysts) directly to carpentry and furniture, breaking formaldehyde down at its source rather than masking it. We verify every job with post-treatment readings in each room, and if any reading rises back above the WHO 0.1 mg/m³ guideline within 30 days, we re-treat free.
How long does treatment take, and when can we move in?
A typical 4-room HDB takes 2–4 hours to treat. We recommend ventilating for 12–24 hours after treatment before moving back in. Post-treatment readings are taken on the same visit, so you leave with your report in hand.
Do I need removal, or just testing?
If your renovation finished recently and there is a noticeable smell, levels are very likely elevated and most owners book treatment directly. If you are unsure — an older renovation, new furniture only, or no obvious smell — a S$180 testing visit gives you room-by-room readings first, and the fee is fully credited if you book removal within 30 days.
Is treatment safe for babies, pregnant women and pets?
The treatment agents we use are water-based and neutral once cured. We ask that the home be vacated during treatment and ventilated for 12–24 hours afterwards, after which it is safe for infants, pregnant women and pets. Families with newborns are one of the most common reasons owners book us.
Which areas of Singapore do you cover?
We cover all of Singapore — HDB, condominium, landed and commercial units island-wide, seven days a week.
