What customers say.
A few of our 4.8★ reviews from Singapore homeowners and businesses.
"Detailed cleaning and formaldehyde removal after our renovation. The crew worked over 9 hours across 5 levels; the air smelled noticeably cleaner and it gave us peace of mind before moving in."

"Post-reno clean with floor scrubbing and formaldehyde removal — the pungent choking smell in all my carpentry is gone, and my floor no longer has that powdery feeling."
Google review
"Chester, Ruman, Sharif and Najeen did a fantastic deep clean — they even measured the before-and-after air quality and the improvement was significant."

What you're paying for
The full Japanese-system treatment.
Photocatalyst spray + activated carbon + measurement before and after. Written out so you know exactly what's done.
What we do
In scope
- Pre-treatment VOC measurement — reading taken before we start
- Photocatalyst spray — titanium-dioxide solution applied to all interior surfaces
- Cabinet + wardrobe interiors — sprayed inside, where off-gas concentrates
- Mattress + sofa surfaces — treated where applicable
- Walls, ceilings, paint surfaces — full coverage
- Activated carbon placement — ongoing adsorption in problem zones
- Air circulation + curing window — we wait for the spray to bind
- Post-treatment VOC measurement — reading taken after, shared with you
- Aftercare instructions — ventilation, what not to do for 24 hours
- Equipment + solution — sprayer, PPE, photocatalyst, carbon, all included
What's NOT included
Quote separately
- Lab-grade certified VOC report (NEA / SAC) — on request, charged separately
- Post-reno surface cleaning — bundle with post-reno cleaning
- Mould / mildew remediation — different treatment, quote separately
- Air purifier supply / install — not in scope
How the treatment runs
Four steps. Photocatalyst + carbon.
The Japanese-system protocol — measure, spray, cure, measure. We share the readings with you.
Photocatalyst spray pass
Titanium-dioxide solution misted onto walls, ceilings, cabinet interiors, wardrobe shelves, mattress, sofa. Light-activated — breaks down VOCs continuously after application.
Cure + activated carbon
30–60 minute cure window. Carbon placed in problem zones (wardrobe corners, cabinet interiors) for ongoing adsorption.
Post-measure + handover
VOC reading taken again. Numbers shared. Aftercare instructions: ventilate, don't wipe surfaces for 24 hours so the photocatalyst binds.
Where the VOCs come from
Three sources we target first.
Formaldehyde concentrates where composite wood, adhesives and new paint meet enclosed air.
Source 01
New cabinetry + wardrobes.
MDF, particleboard, plywood. Urea-formaldehyde adhesives off-gas for months. Cabinet interiors are sprayed first — that's where the concentration peaks.
Source 02
Fresh paint + adhesives.
Solvent-based paint and tile adhesive release VOCs during cure. We treat walls + ceiling within 8 weeks of reno for best result.
Source 03
Mattress + new sofa.
New foam mattresses and sofas off-gas for weeks. Photocatalyst surface treatment + activated carbon nearby.

When you need it
How do I know if I need formaldehyde removal?
Common signs: persistent "new furniture" smell after weeks, eye irritation when you wake up, headaches in a specific room, sore throat that clears when you leave the unit. Most common after a full renovation or after installing new built-in cabinetry, wardrobes, mattresses, or sofas. Children, infants, and asthmatics are most sensitive.
When in the renovation timeline is it best to treat?
Within 4–8 weeks after the last wet trade (paint, adhesive, silicone). That's when off-gas levels peak. Treating too early — while surfaces are still wet-curing — reduces photocatalyst bonding. Treating too late means months of unnecessary exposure.
Will airing out the unit and opening windows fix it?
Ventilation helps but doesn't accelerate the breakdown of formaldehyde locked inside composite wood. Off-gas continues at low levels for 6–36 months from cabinetry. Photocatalyst converts formaldehyde to harmless compounds on contact — ventilation alone takes years.
The treatment
What is the Japanese system you use?
A titanium-dioxide photocatalyst spray combined with activated carbon. The photocatalyst binds to surfaces, then under ambient light it oxidises formaldehyde and other VOCs into water and CO2 at trace levels. Activated carbon adsorbs in low-light zones (cabinet interiors). It's a continuous-action treatment — not a one-time deodoriser.
How long does the treatment last?
Photocatalyst coating is effective for 3–5 years on protected interior surfaces under normal use. Activated carbon needs replacement every 6–12 months in heavy-VOC zones.
Is the spray safe for pets, babies and people with asthma?
Yes. The photocatalyst is water-based, fragrance-free, and food-grade approved in its category. After the 24-hour cure window, the room is safe to occupy. We ask you to vacate during application and for the cure window.
How long does one treatment take?
800 sqft: 3–4 hours including measurement and cure. 1,500 sqft: 5–6 hours. We give you the specific window in the quote.
Bundling
Can you do post-reno cleaning and formaldehyde removal in one visit?
Yes — this is the most common bundle. We clean first (so the photocatalyst binds to a clean surface, not dust), then treat. One crew, one visit, one fixed quote. Post-reno cleaning ›
