Dust, cement stains that won’t clean off, pungent chemical odors upon moving in, nasal allergies, skin sensitivities?

95% of renovation investments fail before move-in due to neglecting Professional Post-Renovation/Pre-move-in Cleaning!

Why is deep cleaning and disinfection necessary after renovation?

您剛完成價值百萬的裝修項目,卻因忽略專業級裝修後清潔,讓家人暴露於甲醛、VOC及致敏原環境中——皮膚科專科醫生林嘉雯於《晴報》明確指出:裝修引發的皮膚敏感一旦爆發,康復期以年計算。 這不僅是健康風險,更是物業價值的隱形損耗。當裝修殘留物侵蝕新居材質、縮短設備壽命時,您的投資回報正在無聲流失。

Renovation companies typically don’t provide thorough post-construction cleanup services—they only clear the most obvious areas. The real health threats hide in places you can’t see: dust in ceiling light troughs, formaldehyde residue inside cabinets, cement stains in window tracks, and paint mist particles in exhaust fans.

Dermatologist Dr. Lam clearly states: Skin allergies triggered by renovation pollutants can take years to recover from once they flare up. This isn’t just a health risk—it’s invisible depreciation of your property’s value. When renovation residues erode new home materials and stains become permanent, your investment returns are silently draining away.

Johnson Group’s post-renovation cleaning service is designed for clients who value time efficiency, family health, and asset preservation. We go beyond surface cleaning with 70 years of expertise, medical-grade natural cleaning solutions, and meticulous finishing standards—so you can move in with confidence the same day, safeguarding your family’s health and property value.

10/10 service!! I was recommended by a friend about Johnson Group and I am beyond satisfied about the service. They are super friendly throughout the entire booking and post-booking process, and they are extremely professional! The guys who came in to do the pest control service were very diligent and meticulous about inspecting every corner/area of the apartment. They also were very patient, kind, and helpful about any further questions I had and gave me good recommendations/advice about the best practices/products for preventing bugs! I would definitely reach out again if I ever have pest issues and recommend them to anyone in the Hongkong area 🙂

The technician was professional and meticulous. Before the procedure, he laid out any potentially contaminated home items, and after finishing, he cleaned the floor before leaving. He also taught us how to prevent mold from recurring. 👍🏻

Add-on Service – New Home Formaldehyde Removal

Post-renovation is the peak period for formaldehyde release. Paint, panels, glue, and furniture continuously emit formaldehyde at its highest concentration, posing the greatest health risk. Professional formaldehyde removal must be preceded by furniture and wall dust/cleaning, as dust and grease can hinder the effectiveness of removal agents, preventing penetration into furniture surfaces or micro-pores.

We recommend new homeowners pair this with our New Home Formaldehyde Removal Service, which includes: Full-home formaldehyde testing, Nano-mist application of internationally certified natural formaldehyde removers to decompose indoor formaldehyde and residual toxins.

We re-test air quality after service and provide free before/after formaldehyde & VOC reports (2 copies) to ensure safe, clean air for worry-free move-in.

建議新屋入伙住戶同時選用我們的專業除甲醛(VOC)服務,包括全屋甲醛檢測、採用具國際認證的天然除甲醛劑在空間霧化噴灑,以分解室內甲醛及殘留有害物質。

Post-Renovation/Move-in Cleaning Pricing

Why Don’t We Offer Fixed Pricing?

Many customers ask: “How much for a 700 sq ft unit?” Professional post-renovation cleaning can’t be answered with a simple flat rate—every unit is unique, and factors beyond size drive costs. We quote based on clear scope, predictable hours, and upfront key cleaning details, listing inclusions/exclusions for fair comparisons. Price isn’t the goal—delivering expected results is.

Key Factors in Our Quotes:

  • Renovation Intensity: Full renovations (wall demolition/plastering) create 3-5x more contamination than partial ones, requiring deeper purification.
  • Property Type & Materials: Premium finishes demand specialized handling.
  • Custom Needs: Add-ons like formaldehyde removal or air quality testing require tailored pricing.
  • Project Complexity: Duplexes/villas or tight deadlines impact final costs.

Safety Assurance & Asset Protection

The key to post-renovation deep cleaning isn’t “brute force,” but “using the right methods.” We tailor cleaning techniques and materials based on surface types and risk areas, prioritizing protection for stone, metal fixtures, glass edges, wood surfaces, and appliance casings to avoid common issues like scratches, hazing, and water marks.

For high-level areas, fragile materials, or special residues, we’ll explain the treatment strategy and limitations upfront before proceeding, ensuring safety and predictable results.


After-Sales Assurance

If any issues arise or standards aren’t met within 48 hours post-service, contact us directly—our team will arrange follow-up and resolution for the best service experience.

Post-Renovation Cleaning FAQs

For a standard residential unit, deep cleaning usually takes one working day with 3-4 technicians. Actual time and manpower may vary based on unit size, renovation complexity, and cleaning difficulty.

We recommend completing it before moving in furniture. Renovation dust, paint residue, and debris often settle into wall corners, floor gaps, and cabinet bases. Cleaning beforehand allows professionals to thoroughly address walls, floors, window frames, lighting, and cabinets, preventing dust buildup and air pollution.

Yes, handle both before move-in: cleaning first, then formaldehyde removal. This sequence optimally reduces indoor pollutants, creating a safe, clean environment for furniture and occupancy.

We maintain fully transparent pricing—all costs and coverage are detailed upfront in the quote with no hidden charges during service.

On service day: Pack valuables/fragiles, empty cabinets if cleaning inside, ensure water/electricity access. We provide all tools and ladders—no customer prep needed.

We use internationally certified natural, green disinfectants—non-toxic, safe for children/pets, effectively removing 99.9% bacteria, viruses, and renovation chemicals.

Customers inspect on-site post-service. If issues arise within 48 hours, contact us—we’ll follow up promptly for full satisfaction.
