🛡 1-Year Warranty — workmanship backed by Larry Contractors. HDB-approved (Licence HB-09-5667H). No middleman, no markup.

How the maths works: Tiling = area in sqft × $11.80 (labour incl. waterproofing & 24-hr ponding test for wet areas). Wall area = perimeter × 2.7m ceiling height (if you enter sqft directly, we estimate the perimeter from a square room — close enough for an indicative figure). False ceiling = floor area × $4.80. Electrical: light/power $90, data $120, isolated powerpoint (oven/hood/hob) $150, 20A isolator (heater) $250 per point. Excludes tile material unless ticked, and hacking / plumbing / sanitaryware which we quote on site.

FAQ

Renovation Cost Calculator FAQs

Common questions from Singapore homeowners — answered honestly.

How accurate is this estimate?
It's a close indicative figure based on our standard direct-contractor rates — tiling $11.80/sqft (including waterproofing and a 24-hour ponding test for wet areas), electrical from $90/point, and fixed packages for painting, flooring, doors and aircon. The exact quote depends on a free site visit, and we're always happy to discuss and optimise the scope with you.
Can I enter the room size in square feet directly?
Yes — each room has a toggle between L × B (length × breadth) and sqft. If you enter sqft directly, we estimate wall area by assuming a roughly square room, which is close enough for an indicative figure. For the exact number we measure on site.
Why is the tile material not included by default?
The $11.80/sqft is the labour + waterproofing rate. Tile material is priced separately because choices vary hugely — standard porcelain is around $3.50/sqft (tick the option to include this budget), while large-format, marble or sintered stone can be several times more. You're free to supply your own tiles or have us source them.
What about hacking, plumbing and sanitaryware?
Those are quoted as a lump sum on the free site visit because they depend on the existing layout and condition. Everything you CAN estimate from room sizes and counts — tiling, electrical points, false ceiling, painting, flooring, doors, aircon — is right here in the calculator.
Do the prices include warranty?
Yes — all works carry a 1-year warranty backed by Larry Contractors, and package items (doors, flooring, aircon) are additionally covered by suppliers we've worked with for decades. One point of contact if anything needs attention: us.
