Renovation Timeline in Singapore: How Long Each Stage Takes

Why You Need a Renovation Timeline

Renovating a home in Singapore is one of the most significant investments you will make. Whether you are working on a BTO flat, resale HDB or private condominium, understanding how long each stage takes helps you plan your move-in date, coordinate deliveries and avoid costly delays.

A well-structured renovation timeline also keeps your contractor accountable. When you know the typical duration for hacking, electrical works and finishing, you can spot red flags early and keep the project on track.

This guide breaks down the typical renovation timeline in Singapore stage by stage, so you can plan with confidence.

Stage 1: Planning and Design (2 to 6 Weeks)

Before any physical work begins, you need to finalise your design, select materials and obtain the necessary permits. For HDB flats, you must apply for a renovation permit through HDB, which typically takes about three working days to process once your contractor submits the application.

During this phase, you will also be choosing your interior finishes. Selecting your flooring, wall treatments and soft furnishings early prevents delays later. Many homeowners underestimate how long material sourcing takes, especially for imported products.

Condominium renovations require approval from your management corporation (MCST), which can take one to two weeks. Some condos have additional restrictions on renovation hours and permitted works, so factor this into your timeline.

Stage 2: Hacking and Demolition (1 to 2 Weeks)

Once permits are approved, the first physical stage involves removing existing finishes, walls or built-in furniture. For a typical four-room HDB flat, hacking usually takes three to five working days. Larger units or extensive demolition work may take up to two weeks.

Key activities during this stage include:

• Removing old floor tiles, wall tiles and ceiling fixtures
• Demolishing non-structural walls (where approved)
• Stripping old bathroom and kitchen fittings
• Disposing of debris through licensed waste removal

HDB restricts renovation noise to weekdays between 9 a.m. and 6 p.m., with no work allowed on Sundays and public holidays. Condo rules may be even stricter, so check with your MCST.

Stage 3: Structural, Electrical and Plumbing Works (2 to 3 Weeks)

This stage covers the essential infrastructure of your home. Electrical rewiring, new power point installations and plumbing rerouting happen simultaneously to save time. If you are building new partition walls or doing any masonry work, this also falls within this phase.

Waterproofing is a critical step that must not be rushed. Bathroom and kitchen wet areas require proper membrane application followed by a ponding test lasting at least 24 hours. Skipping or rushing waterproofing is one of the most expensive mistakes in any renovation.

Air-conditioning installation, including trunking and drainage piping, also happens during this stage. Coordinate your aircon contractor with your main renovation contractor to avoid scheduling conflicts.

Stage 4: Ceiling, Carpentry and Tiling (3 to 5 Weeks)

This is typically the longest stage. False ceiling installation comes first, followed by carpentry works such as wardrobes, kitchen cabinets and shoe cabinets. Tiling of bathrooms, kitchens and common areas usually runs concurrently with carpentry.

If you have chosen vinyl flooring instead of tiles for your living areas, this can significantly shorten your timeline. Luxury vinyl tiles (LVT) can be installed in one to two days for a typical HDB flat, compared to five to seven days for ceramic or porcelain tiles. Explore the range of luxury vinyl options available for faster installation without compromising on aesthetics.

Custom carpentry typically takes two to three weeks for fabrication off-site, plus another week for on-site installation. Built-in wardrobes, TV consoles and platform beds all fall under this category.

Stage 5: Painting, Wallpaper and Finishing (1 to 2 Weeks)

With the major structural and carpentry works complete, painters move in to apply primer and topcoats. Most HDB flats require two to three days of painting for common areas and bedrooms.

If you are using wallpaper or wall coverings, installation typically happens after painting is complete. Professional wallpaper installation for a feature wall takes just a few hours, making it one of the quickest ways to add visual impact.

Other finishing works during this stage include:

• Installation of light fixtures, fans and switches
• Door hardware and locks
• Bathroom accessories such as towel racks and mirrors
• Window grilles and curtain tracks
• Final silicone sealing around countertops and vanities

Stage 6: Cleaning and Defect Checking (3 to 5 Days)

Professional post-renovation cleaning is essential. Construction dust settles on every surface, including inside cabinets and aircon units. Most homeowners engage a professional cleaning service, which takes one to two days for a standard flat.

After cleaning, conduct a thorough defect inspection. Check every room systematically using this approach:

• Test all power points, switches and light fixtures
• Open and close every door and cabinet to check alignment
• Run water in all taps and check for leaks under sinks
• Inspect tiling for hollow spots by tapping with a wooden stick
• Check paint and wallpaper for bubbles, uneven patches or stains
• Verify that flooring is level and free of scratches

Document all defects with photographs and compile a defect list for your contractor. Reputable contractors will rectify defects within one to two weeks.

Total Timeline Summary

Here is a quick overview of how long each stage typically takes:

Stage	Typical Duration
Planning and permits	2 to 6 weeks
Hacking and demolition	1 to 2 weeks
Structural, electrical and plumbing	2 to 3 weeks
Ceiling, carpentry and tiling	3 to 5 weeks
Painting, wallpaper and finishing	1 to 2 weeks
Cleaning and defect checking	3 to 5 days

For a standard four-room HDB resale flat undergoing full renovation, expect the entire process to take approximately 8 to 12 weeks from the start of hacking to move-in. BTO units with minimal hacking may be completed in 6 to 8 weeks, while extensive condominium renovations can stretch to 14 weeks or more.

Tips for Keeping Your Renovation on Schedule

Delays are common in Singapore renovations, but many can be prevented with proper planning. Here are practical strategies to stay on track.

First, finalise all material selections before hacking begins. Last-minute changes to tiles, flooring or countertop materials are the most common cause of delays. Visit showrooms, collect samples and confirm your choices during the planning phase.

Second, maintain a buffer of one to two weeks in your timeline. Unexpected issues such as concealed plumbing problems or supply chain delays for imported materials can push your schedule back.

Third, establish a clear communication channel with your contractor. Weekly site visits and progress updates help you catch potential issues before they snowball into major delays.

Fourth, coordinate your appliance and fixture deliveries carefully. Delayed delivery of a kitchen sink, toilet bowl or air-conditioning unit can hold up entire stages of work. Order these items early and confirm delivery dates with your suppliers well in advance.

Finally, consider using materials that offer faster installation times. Vinyl flooring, for instance, installs significantly faster than traditional tiles and requires no hacking of existing floors in overlay applications. This alone can save you several days on your renovation timeline. Similarly, wallpaper installation is significantly quicker than elaborate paint techniques, and pre-fabricated carpentry components reduce on-site construction time.
