Protecting Your Piano During a Renovation or Painting Job

We can usually tell a piano has lived through a renovation before its owner mentions it: fine grey drywall dust on the soundboard, a haze in the action, a tuning that vanished the week the windows came out. Renovations are quietly one of the more damaging things that happen to home pianos — not from anything dramatic, but from dust, fumes, and climate swings over weeks. The good news: an hour of preparation prevents nearly all of it. Here's the checklist we give clients before the contractors arrive.

The four renovation hazards

Dust. Drywall, sanding, tile cutting, and demolition produce fine abrasive dust that settles inside the piano — on the soundboard, between strings, into the action's felt and centre pins. It's mildly abrasive, mildly hygroscopic (it holds moisture), and impossible to fully remove without a technician's disassembly. Dust in the action is the renovation legacy that shows up as sluggish keys a year later.

Climate swings. Windows out, doors open, heat off for a week in February, or a summer job with the AC off and the house open — a renovation often puts the piano through a season's worth of humidity swings in a fortnight. That's the drift-and-stress cycle that loosens tuning pins and cracks soundboards, compressed.

Fumes and overspray. Paint, stain, polyurethane, and adhesive vapours embed in felt (which is porous) and can haze finishes. Overspray on a piano's case is a refinishing bill.

People. Contractors set tools on lids, lean ladders on cases, roll a piano across a room on bare casters, or "move it out of the way" into the garage. Each is a story we've been called about.

The checklist, in order

1. Decide where the piano will live during the work. Best: a room not being renovated, with its door closed, on the same floor if possible. Interior wall, away from vents and windows as always (placement rules). Never the garage, an unheated porch, or a damp basement — a month there does more harm than the renovation would (why). If it must stay in the work zone, it must be sealed (step 3).

2. Move it properly, or not at all. An upright rolls a short distance across a level floor with two adults and caster cups off (check the casters first); anything involving stairs or a threshold is piano-mover work. Tell the contractors the piano is off-limits to move.

3. Seal it. Close the lid and fallboard. Cover the piano with a breathable moving blanket or cotton sheet first — never plastic directly on the finish, which traps moisture and can mark it — then plastic sheeting over the blanket, taped to itself (not to the piano), reaching the floor. If the piano stays in the work zone, this is non-negotiable; if it's in a closed room nearby, the blanket alone usually suffices, with the door kept shut and a towel along the gap during sanding days.

4. Hold the climate. Keep heat and humidity as normal as the job allows. If the HVAC is off or windows are out for days, a humidifier or dehumidifier in the piano's room and a closed door do real work. A hygrometer beside the piano tells you whether the job is drying or soaking it.

5. Keep fumes away. Painting the piano's room? Move the piano out, or seal it and ventilate hard. Don't paint around it under a sheet.

6. Brief the contractors. One sentence in writing: "The piano is not to be moved, leaned on, or used as a surface." Contractors respect a clear rule; they resent discovering one afterward.

After the renovation

Uncover it, let the house's climate settle for two to four weeks, then book a tuning — the same settling logic as a move. If dust got in despite everything, tell us: a soundboard-and-action cleaning during the tuning visit removes what a homeowner shouldn't attempt (never vacuum inside a piano yourself — dampers and hammers are delicate and lightly attached). Check the finish for overspray or haze while the work is fresh in everyone's memory.

Finally, use the renovation as the moment to get placement right in the finished room — the reason many pianos end up beside a vent is that the furniture went back where it was. A new room is a free chance to put the piano where it should have been all along.

Common questions

Can drywall dust damage a piano?
Yes — it settles inside the instrument on the soundboard and into the action's felt and pivots, where it's abrasive and holds moisture. Sealing the piano before dusty work, and a technician's cleaning after, prevents the sluggish-action problems it causes.

Should I move my piano out of the house during a renovation?
Usually no — moving costs $300–$500 each way and adds two settling periods. A closed room away from the work, sealed properly, is better. The exception is a whole-house gut, where climate-controlled storage beats staying.

Do I need to tune my piano after renovating?
Almost always — the climate swings of a renovation drift it like a move does. Wait two to four weeks for the house to settle, then tune; if dust got in, add a cleaning to the visit.
