TL;DR
The full renovation timeline: from measurement, design and contract to construction and handover — what happens at each stage, how long, and what to watch. A must-read for first-time owners. Use the practical checkpoints below to separate a low-risk next step from work that needs a qualified professional. Keep a written record of the scope, timing and any change agreed on site.
Planning decision checklist
| Stage | Action today | Confirm before proceeding |
|---|---|---|
| Scope | Write down the outcome you need | What is included, excluded and contingent |
| Time | Set a realistic milestone sequence | Access, approvals and disruption constraints |
| Cost | Compare like-for-like quotations | Payment stage, variation process and warranty |
Visual repair guide
For first-timers, the scariest part is not knowing how the process flows or what happens at each stage. According to the Consumer Council, over 30% of renovation complaints stem from misunderstandings caused by 'unclear processes'. Renovation actually follows a clear sequence — understand it and you won't panic. This guide walks through a complete renovation timeline, including timing, costs and things to watch at each stage.
1. Step 1: Measurement and brief (about 1-2 days)
It all starts with a free on-site measurement. The team measures actual dimensions, checks structure and pipe locations, and discusses your lifestyle, household and budget. The clearer this stage, the better the design fits your needs. Prepare in advance: family size and ages, lifestyle habits (e.g. do you cook often), style reference images, and budget range.
2. Step 2: Design and 3D rendering (about 1-2 weeks)
After measurement, the designer produces floor plans and 3D renderings to visualise your unit. You can revise repeatedly here, confirming layout, colours, materials and furniture positions — 'see the finished look before work begins'. Quoting follows design confirmation. Typically includes 2-3 revision rounds; additional revisions may incur extra fees.
OmniFix Decoration uses professional 3D software for renderings — you can clearly see every angle including lighting, textures and colours. Our designers also offer different scheme options based on your budget, ensuring you have clear expectations of the final result at the design stage.
3. Step 3: Quote and contract (about 3-5 days)
Once design is settled, an itemised quote states quantity, unit price and materials for each item. When signing, check: payment stages (usually 3-4 instalments), schedule, warranty terms, and delay liability. Payment ratio should not be front-heavy — e.g. 30% at signing, 40% mid-term, remaining 30% after handover — ensuring you have sufficient bargaining power.
OmniFix Decoration uses design-and-build with transparent quotes and clear contracts. Our quotes are itemised with no vague 'package prices'. If any changes arise during construction, we provide written quotes for your confirmation before proceeding — never acting first and telling later.
4. Step 4: Construction and progress (about 4-12 weeks)
Construction typically follows this sequence:
| Trade | Content | Approx. Time | Notes |
|---|---|---|---|
| Demolition | Remove old decor, clear site | 2-5 days | Load-bearing walls cannot be removed |
| Masonry | Tiling, plastering, waterproofing | 1-2 weeks | Waterproofing must include ponding test |
| Plumbing & Electrical | Re-routing, connections | 1-2 weeks | Photo-document all routing |
| Carpentry | Custom furniture, ceiling | 2-4 weeks | Check board material and edge banding |
| Painting | Skim coat, paint | 1-2 weeks | Ensure good ventilation |
| Installation | Lights, fixtures, cleaning | 3-5 days | Test each function item by item |
The project manager updates progress regularly and communicates issues promptly. A responsible firm has you or a third party inspect key trades (waterproofing, wiring) before continuing. We recommend photographing all routing after plumbing/electrical completion for future maintenance reference.
5. Step 5: Handover and warranty (about 1-3 days)
On completion, a handover inspection checks quality and details. The checklist includes: all switches and sockets working, no tap leaks, cabinet doors opening smoothly, no paint blemishes, no hollow floor tiles, and overall cleanliness. Issues are fixed immediately.
After passing, a proper firm provides a warranty period (typically 1-2 years) for follow-up. Keep your contract and warranty documents safe. OmniFix Decoration provides post-completion warranty service — any construction-related issues within the warranty period are followed up free of charge.
6. Common issues during renovation and how to handle them
First, schedule delays — possibly due to weather, material delivery delays or unexpected issues. Ensure the contract states delay liability and compensation terms. Second, cost disputes — extra problems discovered during construction requiring additional payment. Any additions should be confirmed in writing before execution. Third, communication issues — designate a single contact person (project manager) to avoid miscommunication from multiple channels. Fourth, neighbour complaints — notify neighbours and management before construction and strictly observe work-hour restrictions.
7. Summary: Understanding the process removes renovation fear
Renovation isn't scary — what's scary is starting blindly without understanding the process. Choose the right partner from the start, communicate well and plan properly, and the whole process can go smoothly. If this is your first renovation, contact OmniFix Decoration. Our project managers follow through from measurement to handover as a one-stop service — you just need to wait to move in. WhatsApp free consultation: 9290 2652.
Pre-Commencement Approvals and Demolition Stage Executing a residential renovation in Hong Kong requires rigorous planning due to strict building management regulations, tight urban spaces, and compressed daily working windows enforced by estate management offices. Whether you are upgrading a private estate apartment or an older building, establishing a realistic milestone schedule prevents project overruns, budget stretching, and miscommunication with your contractor. The initial phase, spanning the first three weeks, covers administrative clearance and strip-out work. Before your contractor enters the site, you must secure formal decoration permits from the building management office, settle mandatory renovation security deposits, register worker identity cards, and schedule designated service lift protection times with estate security. Once approved, demolition commences to clear old built-in wardrobes, aging wooden flooring, wall tiles, and non-structural partitions. Inspect the bare concrete slab and load-bearing columns immediately after strip-out finishes. Look out for hairline cracks, water seepage marks, or irregular wall plumbness, and instruct your contractor to rectify these structural anomalies before masonry and wall plastering begin. ### Concealed Services Rough-In and Waterproofing Weeks four through seven focus on structural alterations, electrical rewiring, copper plumbing pipe routing, and air-conditioning drainage installation. Because Hong Kong apartments demand maximum spatial efficiency, mapping out exact furniture layouts, appliance power loads, lighting circuits, and network points prior to wall chasing is crucial for avoiding costly rework. Once concealed conduits are securely embedded, conduct a thorough site walkthrough with your lead technician. Ensure that bathroom and kitchen waterproofing membranes undergo rigorous ponding tests lasting at least forty-eight hours before floor and wall tiles are laid, as moisture leakage is notoriously difficult and expensive to resolve post-completion. Verify pipe pressure testing for water supply lines to prevent hidden leaks behind newly finished walls and ceilings. ### Finishes, Carpentry Installation, and Final Handover The final stretch, covering weeks eight through eleven, involves wall skim-coating, premium painting, tile installation, custom cabinetry fitting, and final fixture assembly. Final measurements for built-in furniture should be taken only after wall plastering is fully completed to guarantee precision against uneven concrete surfaces. Upon substantial completion, perform a comprehensive defect inspection with your site supervisor. Check window silicone seals, door latch alignments, sanitary ware drainage, and socket voltage outputs. Document all minor imperfections in a detailed punch list for immediate rectification before releasing the final retention payment and moving in with your family smoothly. <!-- P2-CONTENT-EXPANSION -->

Frequently asked questions
How long is the whole process?
Depends on size and scope. A 300-sqft basic renovation takes about 6-8 weeks; a 500+ sqft full renovation about 10-16 weeks. Confirmed by schedule after measurement.
Can I live in the unit during renovation?
Generally not recommended. There's dust, noise and safety risks during construction. If only doing partial renovation, discuss phased construction with the contractor.
How to avoid renovation disputes?
Most importantly: clear contracts, written confirmation for any changes, and keep all communication records. Choosing a reputable firm with transparent quotes and doing inspections at key stages greatly reduces dispute risk.
