Perfect subfloors. Seamless repairs.

Why subfloor prep matters

Most Melbourne subfloors — particularly older slabs and re-stumped timber — have dips and rises of 5–20mm. Installing hybrid or timber over those imperfections leads to clicking, gapping and voided warranties. We survey with laser and straight-edge, grind high spots, prime, then pour a premium self-levelling compound to spec.

Repairs that disappear

Don't replace what can be revived. We source matching boards or carefully craft replacements, weave them into the existing layout, then sand and coat the surrounding area so the repair vanishes into the original floor. No visible patches, no obvious 'fixed' zones.

Full sand & refinish

Three-pass sanding with dust-controlled machines, edging to skirtings, optional stain, then premium two-pack polyurethane or hardwax-oil finish in matte, satin or gloss. Walk on it the next day, full cure within a week.
