Drywall Installation & Repair near you in Hong Kong

Usually not. Most drywall contractors leave the wall sanded and primed (or just sanded), ready for your painter. Ask explicitly — some will prime and paint the patch for an extra fee, but colour-matching an aged painted wall often means repainting the whole wall.

Hairline cracks at joints and above door frames are usually seasonal movement and are cosmetic. Wide (over 3 mm), diagonal, or recurring cracks, or cracks paired with sticking doors, can indicate settlement — get a builder or structural engineer to look before patching.

Drywall (plasterboard) repair replaces or patches board sheets and finishes the joints with tape and compound. Traditional plastering applies wet plaster coats over masonry or lath. Older homes often have solid plaster walls that need a plasterer, not a drywall contractor.

If board has swollen, sagged, or grown mould it must be cut out and replaced — drying alone is not enough. Fix the leak first, cut back at least 30 cm beyond visible damage, and let the cavity dry before new board goes in. Persistent damp needs a moisture-meter check.

Yes, almost all do. Small patches are priced as a minimum call-out (often 1-2 hours of labour plus materials) because of travel and return visits for coats. Bundling several small repairs into one visit is the cheapest way to get patches done.

Small patch repairs (nail holes, door-knob dents) typically run the price of a 1-2 hour call-out, while larger holes or water-damaged sections cost more because they need cutting back to studs, new board, taping and up to three coats of joint compound. Whole-wall or ceiling replacement is priced per square metre or square foot.

Commonly the upstairs owner is liable if the leak originates in their flat. The FEHD/BD Joint Office can investigate persistent seepage. Repair your ceiling only after the source is fixed, or the damage will recur.
