Make your next renovation a better decision.

Two to three months before you collect your keys is the sweet spot. At that point your floor plan is enough to start planning layout, storage and electrical positions, and you have time to compare firms properly rather than signing under pressure. Homeowners who start after collection often rush decisions that are expensive to undo later — power point positions and hacking works in particular.

There is no honest single answer, and be wary of anyone who gives you one before seeing your home. The cost of the same flat can differ by tens of thousands depending on how much carpentry you need, whether wet areas are being hacked and re-waterproofed, and what condition the existing electrical and plumbing are in. What we can tell you is what moves the number, and we will give you a considered figure after a site assessment rather than a headline price designed to win the job. If a quote arrives without anyone having visited your home, treat the number as a marketing figure, not a cost.

Check three things before anything else. First, that they are HDB-registered if you are renovating an HDB flat — only registered contractors can apply for the permits, and the register is publicly searchable. Second, whether they hold CaseTrust–RCMA accreditation, which requires a standard contract and a dispute resolution process. Third, that the company has a real UEN, a physical address you can visit, and a track record you can verify. A firm that cannot produce these is asking you to take a large financial risk on trust alone.

Vinyl is the most popular choice in Singapore flats now: it is water-resistant, warm underfoot, quick to install and can be laid over existing flooring, which saves hacking cost. Tiles are the most durable and best for wet areas and heavy use, but they are cold, harder underfoot and more expensive to install. Laminate looks good but tolerates moisture poorly, which matters in a humid climate and in homes with children. For most HDB renovations, vinyl through the dry areas and tiles in the wet areas is the practical answer.

For a typical HDB flat, budget eight to sixteen weeks on site, depending on how much hacking and carpentry is involved. Add four to eight weeks before that for design, selections and permit approval. Timelines are driven by sequencing — wet works, then electrical and plumbing, then carpentry, then finishing — so a delay early on pushes everything behind it. Most overruns come from late material selections or mid-build changes rather than from the building work itself.
