💡 Key Takeaways
- Post-renovation disinfection eliminates construction dust, bacteria, and airborne contaminants
- ULV fogging reaches ceiling corners, air ducts, and hidden spaces that manual cleaning misses
- Surface disinfection targets 40+ high-touch points throughout the home
- The entire process for a link home takes approximately 2.5 hours
- Families can safely move in within 2 hours after treatment completion
Project Overview
In February 2026, a homeowner in Subang Bestari contacted Mr Pest Control Shah Alam to arrange a full disinfection service for their recently renovated 3-bedroom link home. The family had completed an extensive kitchen and bathroom renovation and wanted the entire house professionally disinfected before moving their children back in.
Subang Bestari is a well-established residential township in the northern Shah Alam corridor, primarily comprising double-storey link homes built in the early 2000s. Many homeowners in the area are now undertaking renovations as properties reach the 20-year mark — and post-renovation disinfection has become an increasingly common request.
Client Situation
The homeowner — a young family with two children aged 3 and 6 — had been living with relatives during a 6-week renovation that included full kitchen cabinet replacement, bathroom retiling, ceiling repairs, and fresh paintwork throughout the ground floor. Construction debris had been cleared, but fine dust remained embedded in corners, air conditioning vents, and behind built-in furniture.
The client's primary concerns were:
- Residual construction dust and chemical fumes from paint, adhesives, and grout
- Bacterial contamination from construction workers using the bathrooms over 6 weeks
- Potential mould growth in enclosed spaces that had been sealed during renovation
- Safety for young children who spend significant time on the floor
Assessment Findings
Our technician conducted a walkthrough inspection before beginning treatment. Key findings included:
- Fine particulate dust on all horizontal surfaces including ceiling fan blades, air conditioning vents, window ledges, and inside wardrobes
- Adhesive residue and grout haze on newly tiled bathroom floors and kitchen backsplash
- Musty odour in the master bedroom wardrobe area — early signs of moisture trapped during renovation
- Paint fumes still detectable in the ground floor living area and stairwell
- Bathroom fixtures showing water stain marks and construction grime around toilet bases and sink edges
The property measured approximately 1,400 sq ft across two floors — a typical layout for Subang Bestari link homes with 3 bedrooms, 2 bathrooms, a living room, kitchen, and small backyard utility area.
Treatment Approach
We deployed a two-phase disinfection protocol specifically designed for post-renovation residential properties:
Phase 1 — ULV Fogging (Ultra-Low Volume)
Using a professional ULV fogger, we dispersed hospital-grade disinfectant throughout the entire house. The ULV machine produces droplets between 5 to 50 microns — fine enough to remain suspended in the air for several minutes, reaching:
- Ceiling corners and coving where dust accumulates
- Inside air conditioning ducting and return vents
- Behind built-in wardrobes and kitchen cabinets
- Under staircase void and enclosed utility spaces
- Between window louvres and sliding door tracks
The disinfectant used was a quaternary ammonium compound (benzalkonium chloride-based) approved by the Malaysian Ministry of Health for residential use. It is effective against bacteria, viruses, fungi, and mould spores while being safe for indoor environments once dried.
Phase 2 — Surface Disinfection
After fogging, our team performed targeted surface disinfection on all high-touch and high-risk areas:
- Kitchen: All new cabinet interiors and exteriors, countertops, sink basin, tap handles, stove area, and electrical switch plates
- Bathrooms: Toilet bowls, cisterns, flush handles, shower screens, tap handles, towel rails, and newly tiled floor surfaces
- Bedrooms: Door handles (both sides), wardrobe interiors, window handles, light switches, and power outlets
- Common areas: Staircase handrail, main door handle and lock, shoe cabinet interior, and living room electrical points
We logged over 40 individual touch points treated with direct-application disinfectant — a medical-grade hydrogen peroxide solution that evaporates cleanly without residue.
Products Used
- ULV Fogging: Benzalkonium chloride 5% solution (KKM-approved, EN 14476 certified)
- Surface Treatment: Accelerated hydrogen peroxide 0.5% (AHP) — hospital-grade, no-rinse formula
- Odour Neutraliser: Enzyme-based air treatment for paint fume reduction
Results
The entire treatment was completed in 2 hours and 40 minutes. Post-treatment inspection confirmed:
- All visible dust and particulate matter eliminated from treated surfaces
- Musty odour in master bedroom wardrobe fully neutralised
- Paint fumes significantly reduced — client confirmed no detectable smell on re-entry
- All bathroom and kitchen surfaces visibly clean and disinfected
- Air quality noticeably improved throughout the property
The family moved in the following day after allowing a full 12-hour ventilation period with windows open — exceeding our minimum 2-hour recommendation as an extra precaution with young children.
Follow-Up
We conducted a courtesy follow-up call 7 days after treatment. The client reported no issues — no allergic reactions from the children, no recurring odours, and overall satisfaction with the cleanliness of the home. We recommended a follow-up disinfection service in 6 months as part of routine home hygiene maintenance.
Cost and Timeline
For a standard 3-bedroom link home in the Shah Alam area, post-renovation disinfection typically ranges from RM350 to RM550 depending on property size and level of treatment required. This project was completed at RM450 — inclusive of ULV fogging, surface disinfection, and odour treatment.
Booking to completion took 3 days — the client contacted us on a Monday, we scheduled the walkthrough for Tuesday, and treatment was completed the same day.
