Case Study 1: KLGCC East Residence Terrace Villa, Bukit Kiara

4-Storey Terrace Villa · KLGCC East Residence, Bukit Kiara · ~5,000 sqft · 27 April 2026

Inspector: Mr. Vin, Senior Hygiene Inspector · Equipment: HIKMICRO Thermal Camera, Protimeter Surveymaster, 6-in-1 Air Quality Monitor

Property Context

A multi-storey terrace villa within KLGCC East Residence in Bukit Kiara, the premium golf-club residential enclave adjacent to the Kuala Lumpur Golf & Country Club. The lower-ground level serves as the grand entrance with vehicle parking; living areas open directly off this entrance level. Architectural risk identified: living-area shoe-rack and entrance zones inherit garage-level humidity, vehicle-borne moisture (rain, wet shoes), and reduced cross-ventilation. Hidden mould at the entrance shoe-rack was diagnosed as a structural-design risk inherent to this build, not a housekeeping failure. This pattern is common across multi-storey KLGCC East Residence villas.

Rooms Inspected (15 zones)

Master Bedroom Suite, Bedrooms 2 to 5, Living Room (entrance level), Dining Area (1st Floor), Kitchen, three full bathrooms, Guest Toilet (ground floor), Middle Toilet (2nd Floor), Master Ensuite (2nd Floor), Music Room (2nd Floor), Shoe Cabinet (interior), Staircase / Common.

Critical Finding 1: 1st-Floor Toilet (most severe contamination)

Diagnosis: Yes: extensive, multi-surface visible mould; 8 UV-light photographs documented widespread hidden contamination. Patterns identified included diffuse fluorescent bloom radiating from LED downlight + extract vent (indicating condensation on cooler metal housing OR moisture ingress from above); dense full-surface mould colonisation across MDF cabinet doors acting as moisture sponges; concentrated bloom in centre of ceiling access hatch (historical water track); heavy stippling at door frame / architrave corner junctions (classic condensation cold-spot pattern); diffuse colonisation across plain wall area; poor sealing at door & architrave around glass-pane door junction.

Critical Finding 2: 1st-Floor Dining Area

Diagnosis: Severe hidden contamination at the wall-ceiling junction adjacent to an AC condensate drip-pan. Thermal imaging revealed a temperature differential exceeding the moderate threshold, indicating active moisture beneath visible surface.

Critical Finding 3: 2nd-Floor Middle Toilet

Diagnosis: Active mould colonisation behind the toilet tank wall and in the ceiling cavity above. Protimeter Surveymaster readings in the >200 (Wet) range.

Rooms in Good Health

Master Bedroom Suite, Kitchen, Top Floor: All air-quality readings within Safe range. Hygrometer 40 to 60% RH. No visible or UV-detected mould. No remediation required.

Executive Summary Issued to Homeowner

Mixed indoor-environment profile: several rooms in good health (master bedroom suite, kitchen, top floor); three rooms (1st-floor toilet, 1st-floor dining area, 2nd-floor middle toilet) require structural remediation, not surface treatment. Recommended protocol: HEPA-13 containment, substrate extraction of contaminated MDF cabinet doors and ceiling gypsum, photocatalytic anti-microbial coating, post-treatment independent laboratory verification.

Outcome

Written diagnostic report delivered to homeowner within 48 hours of inspection. Customised remediation quotation included. Inspection fee fully credited toward subsequent remediation project.

Case Study 2: Mont Kiara Condominium Master Ensuite

High-Rise Condominium, Mont Kiara · Master Ensuite Contamination · 29 April 2026

Inspector: Mr. Vin, Senior Hygiene Inspector · Homeowner reference: Ms. T (Australian expatriate family)

Property Context

Premium high-rise condominium in Mont Kiara, Kuala Lumpur. International family relocated from Sydney 18 months prior. Master ensuite bathroom developed black staining on the gypsum ceiling near the split-system AC unit. Homeowner had attempted bleach treatment twice over 18 months; mould returned within 6 to 10 weeks each time, a common pattern in Mont Kiara high-rise condominium ensuites where AC drip-pans overflow during humidity spikes.

Diagnostic Findings

76%

CO₂

1,150 ppm

PM2.5

28 µg/m³

HCHO

0.12 mg/m³

Protimeter

240

Root cause identified: AC condensate drip-pan overflow had saturated the gypsum board above the ceiling, with concealed contamination extending approximately 8× the area of the visible surface stain. Bleach treatment had addressed the visible 5%, leaving 95% of the contamination intact behind the ceiling.

Remediation

HEPA-13 containment, full extraction of contaminated gypsum ceiling section, AC drip-pan replacement and rerouting of condensate line, photocatalytic anti-microbial coating applied to all exposed substrates, ceiling rebuild, post-treatment independent lab verification confirming species levels below DOSH ICOP IAQ 2010 thresholds.

Case Study 3: Ricoh-Equivalent Corporate Office IAQ Audit, Selangor

Corporate Office, Selangor · IAQ Compliance Audit · May 2026

Inspector: Mr. Vin, Senior Hygiene Inspector · Engagement: Multinational business-services firm

Brief

A multinational business-services corporation operating in Selangor required an indoor air quality compliance audit ahead of an internal occupational-health review. The 13-point hygiene science methodology was applied to all occupied zones. This is the standard format Cleanaholics delivers for corporate clients requiring DOSH ICOP IAQ 2010 compliance documentation.

Outcome

All air-quality readings within DOSH ICOP IAQ 2010 acceptable limits. Two zones flagged for elevated CO₂ during peak occupancy (1,050 ppm and 1,100 ppm); ventilation adjustment recommended. Written compliance documentation delivered for internal records.

Case Study 4: Rawang Family Home Post-Renovation Formaldehyde

2-Storey Link House, Rawang · Post-Renovation HCHO Remediation · 14 May 2026

Inspector: Mr. Vin, Senior Hygiene Inspector · Homeowner reference: Mr. A (young Malaysian family)

Brief

Newly renovated family home in Rawang, Selangor. Young Malaysian family moved in 3 weeks post-renovation; mother reported persistent headaches, child developed nighttime cough. Classic post-renovation MDF off-gassing pattern increasingly common across newer Rawang and Selangor developments.

Critical Finding

HCHO 0.18 mg/m³ in master bedroom (Poor, almost 2× the safe threshold of 0.08 mg/m³). Source: newly installed MDF wardrobe behind the bed-head wall. TVOC also elevated at 0.6 mg/m³ from fresh paint cure.

Remediation

Photocatalytic anti-microbial coating applied to MDF wardrobe surfaces. HEPA-13 air scrubbing for 72 hours. Post-treatment HCHO measured 0.06 mg/m³ (back into Safe range). Family reports symptoms resolved within 10 days of treatment completion.

Case Study 5: Ukay Heights Landed Residence, Ampang

Engagement: Hygiene investigation for Dato' L, a private landed residence in Ukay Heights, Ampang (June 2026). After floor polishing works, the family noticed a reddish residue on a third-floor wall and wanted to know whether it was harmless polishing dust or something biological.

Method: Non-invasive investigation by our Senior Hygiene Inspector: visual walkthrough with photographic record, INKBIRD multi-sensor readings for air quality, humidity, carbon dioxide and particulates, and Protimeter Surveymaster in-material moisture readings across the affected and adjacent walls.

Findings and outcome: The investigation documented the residue, the moisture condition of the wall behind it and the hygiene state of every room made available, and set out honestly where a firm identification would require laboratory swab sampling rather than visual assessment. The owner received a written confidential investigation report answering the question that prompted the visit, with a clear record to act on. No treatment was sold on the day; the engagement was investigation and findings only, which is exactly what the situation needed.

Why this matters: an honest inspection company tells you when something does not need remediation. That discipline is why our reports are trusted as documentation, including for insurance and tenancy purposes.

Case Study 6: Post-Sewage Recovery, Subang Jaya Family Home

Engagement: Assessment for Puan R in Subang Jaya, Selangor (June 2026), after a sewage event affected the ground floor of the family home. The family needed to know what the event had left behind, whether hidden mould was developing, and what it would take to make the floor genuinely safe again.

Method: Full ground-floor assessment by our Senior Hygiene Inspector: hidden-mould inspection of walls and ceilings, thermal imaging for surface-temperature and condensation mapping, and instrument readings captured on site.

Findings and outcome: The inspection documented the post-sewage condition room by room and identified the areas requiring biohazard-grade treatment rather than ordinary hygiene science. The family received a written report with a considered two-programme treatment plan, separating what was urgent from what could wait, so they could make decisions on evidence instead of fear.

Why this matters: after sewage exposure, surfaces can look clean while carrying a real biological load. Instrument-based assessment shows where treatment is genuinely needed, and where it is not.

What These Case Studies Demonstrate

Standard "mould remediation" misses 70-95% of the contamination. Visible surface staining represents a small fraction of the actual fungal load in the substrate behind it.
Architecture is often the root cause. Buildings designed with garages at entrance level, AC drip-pans over occupied gypsum ceilings, or MDF-heavy interiors are structurally prone to mould. Cleanaholics' inspection identifies the root-cause architectural risk, not just the surface symptom.
Quantitative diagnostics replace guesswork. Cleanaholics' 13-point methodology generates ~143 individual data points per inspection (for a 4-bedroom home), each compared against DOSH ICOP IAQ 2010 thresholds. The homeowner receives measurements, not opinions.
Verification closes the loop. Post-treatment independent-laboratory sampling proves the remediation worked, which separates Cleanaholics from contractors who declare completion based on visual inspection alone.
