The reason 'one stop' is actually true.
Disinfection with NEA-recommended chemistry. Formaldehyde removal using a Japanese system. Painting and renovation works as a direct BCA-licensed contractor — not subcontracted to whoever's free. The specialist pillar is what makes OCD a single vendor for the whole post-renovation chain.
Disinfection fogging, mid-job
What sits in this pillar.
Two are chemistry-led (disinfection, formaldehyde). Two are construction-side (painting, renovation works). The dual NEA + BCA licensing is what makes all four legally bid-able under one company.
Disinfection services
Fogging-based, NEA-aligned QAD chemistry. Homes, offices, restaurants, childcare, schools.
Formaldehyde removal
Japanese air-purification system. IAQ test, custom treatment, verification test after.
Painting services
Residential, commercial, reinstatement. Furniture protection, contained workspace, no mess behind.
Renovation works
Painting, hacking, electrical, partitions, screeding, tiling, vinyl install, carpentry. Direct contractor.
Most cleaning companies can't do half of this.
In Singapore, cleaning is licensed by NEA. Renovation works is licensed by BCA. Most operators hold one or the other — which is why customers normally end up with two vendors. OCD holds both. The bundle isn't a marketing claim; it's an operating licence.
NEA-aligned chemistry
Disinfection uses Quaternary Ammonium Compound — the chemistry NEA recommended in its N-Coronavirus advisory. Alcohol-free, rinse-free, baby and pet safe.
Japanese formaldehyde system
Four-step process: IAQ test, custom plan, treatment, verification test. Branded system from Japan targeting the VOCs released by new cabinetry, flooring, paint, and adhesives.
Direct contractor, not a middleman
Painting and renovation works are own-services under our BCA contractor registration. No subcontracting markup, no scheduling lag between trades.
Reinstatement covered
End-of-lease painting and handing-over works for tenants — paired naturally with move-out cleaning. One job sheet, one invoice, one crew framework.
After a 4-room HDB renovation.
The same family normally hires four vendors. OCD does the whole sequence.
Post-reno clean
Dust, paint marks, debris removed from every surface in the standard 14-item scope.
Formaldehyde removal
IAQ test before, Japanese treatment, verification test after. New furniture and cabinetry are the source.
Marble polish
Optional — bathroom or living-area marble that picked up scratches during reno.
Touch-up painting
Reinstatement painting for the spots the renovation contractor missed or the move-in damaged.
Cleaning and floor restoration.
Before you book specialist work.
Is the disinfection chemistry safe around children and pets?
Yes. Alcohol-free, rinse-free, non-toxic. The QAD chemistry is the ingredient NEA recommended in its N-Coronavirus advisory.
Does formaldehyde come back after treatment?
New furniture continues to off-gas over time, so concentrations can rise again. The verification test after treatment confirms the immediate result; ongoing levels depend on what's in the home.
What renovation works do you do in-house vs subcontract?
Painting, hacking and reinstatement are direct. Electrical works require an EMA-licensed worker on the job. The full trade breakdown is in the renovation-works page.
Can I bundle painting with my post-renovation clean?
Yes, and that's the common pairing. Touch-up painting after move-in is the standard reinstatement scope; one job sheet covers both.
