Renovation Timeline in Singapore (Week by Week)

Most Singapore home renovations take about 8 to 12 weeks of on-site work once demolition starts. A light cosmetic refresh can finish in 3 to 4 weeks, while a full gut renovation of a resale flat or a large condo can stretch to 14 weeks or more. The exact length depends on the scope, the size of the unit, whether you are moving walls, and how quickly you make decisions.

Those figures cover construction only. If you count planning, design, quotation and permit approval before any hacking happens, the whole journey from first contractor meeting to move-in is usually 4 to 6 months. Knowing where the time goes helps you set a move-in date you can actually keep.

How long does a renovation take in Singapore overall?

As a rough guide, plan for the following ranges. These are typical, not guaranteed, and any single project can run shorter or longer.

• Cosmetic refresh (painting, some carpentry, new fixtures): 3 to 4 weeks
• Standard HDB or condo renovation (kitchen, bathrooms, built-ins, some layout changes): 8 to 10 weeks
• Full gut renovation of a resale flat or older condo (rewiring, replumbing, hacking walls): 10 to 14 weeks or more
• Planning and permits before work starts: add 4 to 8 weeks on top

What happens in weeks 1 to 2 (demolition and hacking)?

Once permits are approved and you hand over the keys, the first phase is protection and demolition. The contractor lays floor protection, seals off common areas, and hacks out old tiles, cabinets, and anything being replaced. For HDB flats, hacking hours are restricted and noisy work is only allowed on weekdays and Saturdays within set times, with no such work on Sundays and public holidays.

This stage is fast but disruptive. Debris removal and clearing the space usually wraps up by the end of week two, leaving a blank canvas for the trades that follow.

What happens in weeks 3 to 5 (wet works, wiring and plumbing)?

This is the hidden but critical phase. Electricians run new wiring and add or relocate power points, and plumbers reroute water and waste pipes for kitchens and bathrooms. Waterproofing goes down in wet areas, followed by masonry and any new brick walls or hacked openings.

Getting the electrical and plumbing right at this stage matters, because it is buried behind tiles and walls afterward. If you want the wiring, pipework and waterproofing handled properly alongside the building work, our renovation team coordinates the electrical and plumbing trades so nothing has to be reopened later.

What happens in weeks 5 to 8 (tiling, carpentry and ceilings)?

With the wet works cured, tilers lay floor and wall tiles, then false ceilings and cove lighting boxes go up. Carpentry is often the longest single item: kitchen cabinets, wardrobes, and feature joinery are usually built off-site in a workshop, so allow 3 to 5 weeks from confirmation of the final measurements to installation.

Because carpentry runs on its own lead time, confirm your designs and materials early. A late change to a cabinet layout or a laminate colour can push the whole schedule back by a week or two.

What happens in weeks 8 to 12 (finishing and handover)?

The final stretch covers painting, installing sanitary fittings, lights, switches, and appliances, plus glasswork like shower screens and mirrors. The contractor then does touch-ups, a full clean, and a defects check with you before handover.

Walk through the unit carefully at this point. Note any chips, uneven paint, misaligned doors, or fittings that do not work, and give the contractor a written defects list so they can rectify before you release the final payment.

What causes renovation delays in Singapore?

Most overruns are not caused by the building work itself. They come from decisions and approvals that stall the trades waiting on site.

• Slow permit approval, especially HDB renovation permits and any work needing MCST approval in condos
• Late design decisions, such as changing layouts, tiles, or carpentry after work has started
• Long material or appliance lead times, including imported tiles and custom stone
• Peak-season backlogs around year-end and before major festive periods
• Additional works discovered after hacking, like old pipes or wiring that must be replaced

How can you keep your renovation on schedule?

The single biggest lever is finalising decisions before demolition begins. Lock your floor plan, tile choices, carpentry designs, and appliance list early, and order long-lead items ahead of time. Keep a shared schedule with your contractor and check progress against it weekly.

Build in a buffer of one to two weeks before booking movers or utilities. A realistic move-in date with slack is far less stressful than a tight one that slips at the last minute.

Frequently asked questions

How long does an HDB renovation take? A typical HDB flat renovation runs about 8 to 12 weeks of on-site work once hacking starts, though a light refresh can be done in 3 to 4 weeks and a full gut of a resale flat can take longer. Add several weeks before that for design, quotation, and HDB permit approval.

Can I speed up my renovation? To a point, yes. Finalise all your decisions before work begins, order carpentry and long-lead materials early, and keep payments and approvals moving so trades are never left waiting. You cannot safely rush curing times for waterproofing or the workshop lead time for custom carpentry.

When can renovation work be done in HDB flats? Noisy renovation work such as hacking and drilling is allowed on weekdays and Saturdays within set hours, and is not permitted on Sundays or public holidays. Quiet works have more flexibility, but always confirm the current HDB rules and inform your neighbours in advance.

Should I stay in my home during renovation? For a full renovation it is usually easier to move out, since there will be no working kitchen or bathroom for weeks and the dust and noise are significant. For a small cosmetic refresh you may be able to stay, but expect disruption in the affected rooms.
