How Should You Store a Piano?
Store a piano in a climate-controlled space with stable temperature and humidity around 40–50%, never a garage, attic, or damp basement. Cover it with breathable pads rather than plastic, keep it off exterior walls, and plan a tuning after storage. Climate-controlled storage costs about $50–$150 per month in 2026.

What a piano needs in storage
A piano is mostly wood, felt, and metal under a lot of string tension. Wood takes on and releases moisture as the air changes, and that movement is what damages pianos in storage. The goal is simple: keep the environment stable.
Two numbers matter:
- Humidity around 40–50%. This is the usual target range. Steinway cites 45–50% relative humidity as the optimum for its pianos.
- Stable temperature. A normal indoor range, held steady. The exact figure matters less than avoiding big daily and seasonal swings.
Stability is the real point. A piano kept at a steady 40% will usually fare better than one that swings between 30% in winter and 70% in summer. Big swings drive the soundboard to swell and shrink, which is how cracks, loose tuning pins, and sticking keys start.
Why garages, basements, and attics hurt pianos
These spaces are the usual first idea because they’re free. They’re also where stored pianos get damaged.
| Space | Main problem | What can happen |
|---|---|---|
| Garage | Tracks outdoor temperature and humidity | Tuning instability, soundboard stress, rust on strings |
| Attic | Heat buildup in summer, cold in winter | Glue joints weaken, finish damage, cracks |
| Unfinished basement | High humidity, possible flooding | Swollen wood, sticking keys, rust, mold on felts |
| Outdoor shed or non-climate unit | Full seasonal swings | All of the above, plus pests |
| Climate-controlled storage | Stable conditions by design | Minimal risk if the piano is prepped well |
| Interior room at home | Usually stable if heated and cooled | Low risk, away from vents and windows |
A finished, dry basement with steady heating and cooling can be fine. The test is whether the space holds steady year-round, not what it’s called. A cheap hygrometer will tell you.
Short-term vs long-term storage
Short term (days to a few weeks). A dry, interior room is usually enough. This covers the gap between move-out and move-in, or a renovation. Keep the piano covered and away from heat sources.
Long term (months or more). Use climate-controlled storage. The longer the piano sits, the more a poor environment costs you. Check on it if you can, and confirm the facility actually controls humidity, not just temperature. Some “climate-controlled” units only heat and cool.
If you’re storing a piano because you’re unsure whether to keep it, read is it worth moving a piano. Paying months of storage for an instrument you’ll later sell rarely makes sense.
How to prep a piano for storage
Good prep prevents most storage problems.
- Clean it. Dust the case and wipe up anything sticky. Don’t spray cleaners inside the piano.
- Close the lid and fallboard. This keeps dust and pests off the keys and strings.
- Cover it with breathable material. Use moving pads or a fitted cloth piano cover. Don’t wrap plastic directly against the finish, since it can trap moisture. If you want a dust barrier, put it over the pads.
- Keep it off exterior walls. Outside walls run colder or warmer than the room. Leave a gap of a few inches from any wall.
- Raise it off concrete if possible. A pallet or platform keeps it away from floor moisture.
- Keep it away from vents, windows, and doors. Direct airflow and sunlight cause local swings.
- Don’t stack anything on top. Weight on the lid can warp it or crack the finish.
For a grand piano, how it’s stored depends on the facility. Some keep grands on their legs, others on the skid board. Let a piano mover handle the move in and out. A grand piano is never a DIY job, and storage doesn’t change that.
How to choose a storage facility
Not every facility that says “climate controlled” is suited to a piano. Ask these questions before you book, and get the answers in writing where you can.
| Question | Why it matters |
|---|---|
| Do you control humidity, or only temperature? | Humidity swings do most of the damage to pianos |
| What range do you hold, and do you monitor it? | A stated range and a log beat a vague promise |
| Is the space indoors, with no roll-up door to the outside? | Exterior doors let in outside air every time they open |
| Who moves the piano in and out? | Storage staff without piano experience are a risk |
| What coverage applies to the piano while stored? | Your homeowner’s or renter’s policy may or may not extend to it |
| Can I visit or check on the piano? | Useful for long stays |
| How are grands stored, on legs or on the board? | Shows whether they handle pianos regularly |
Piano movers that run their own storage tend to have good answers to most of these, since the piano stays with the same people from pickup to redelivery. A self-storage facility can still work, but you’ll need to arrange the moves yourself and check the unit’s conditions.
Check your own insurance as well. Some homeowner’s and renter’s policies cover belongings in storage and some limit it, so read your policy or ask your insurer before the piano leaves the house.
What piano storage costs
Climate-controlled storage costs about $50–$150 per month. This is an approximate 2026 US ballpark that varies by region, unit size, and piano type, so get quotes.
Two common options:
- Piano mover storage. Many piano movers run their own climate-controlled storage and price it per piano, with uprights at the low end and grands higher. Current listings from piano movers in several US cities mostly fall in about the $60–$150 per month range.
- Self-storage unit. A climate-controlled unit big enough for a piano can land anywhere in the range and above it in expensive cities. Current 2026 listings for a climate-controlled 10x10 run from under $100 in some cities to over $200 in others.
Add the move into storage and the move back out. Each is a separate piano move, priced like a local move: about $250–$600 for an upright and about $500–$1,200 for a grand, ground floor to ground floor (approximate 2026 ballparks). Stairs and tight access add to that. The cost calculator gives a quick estimate for each leg.
| Item | Approximate 2026 cost |
|---|---|
| Climate-controlled storage | About $50–$150 per month |
| Move into storage (local, upright) | About $250–$600 |
| Move into storage (local, grand) | About $500–$1,200 |
| Move back out | Same as moving in |
| Tuning after storage | Roughly $100–$250 |
What happens after storage
Expect the piano to be out of tune when it comes out, even after good storage. The move itself shifts it, and the new room’s conditions differ from the facility’s.
Most technicians suggest waiting about 2–4 weeks for the piano to acclimate before tuning. A tuning runs roughly $100–$250 in 2026, varying by area. After long storage, the pitch may have dropped enough to need extra work, which costs more. See piano tuning after moving.
Before you book the tuning, check the piano yourself. Play every key, press every pedal, and look for cracks, loose veneer, or sticking keys. Report any damage to the storage provider or mover in writing, following their claim process.
If storage is part of a longer relocation, long-distance piano moving covers transit, coverage, and costs.

Frequently asked questions
Can you store a piano in a garage?
It's a bad idea. Most garages swing through outdoor heat, cold, and humidity, and those swings are what crack soundboards and loosen tuning pins. A garage is fine for a few hours on moving day, not for weeks or months.
What humidity should a piano be stored at?
Around 40–50% relative humidity is the usual target, and Steinway cites 45–50% as ideal for its pianos. Stability matters as much as the number, so a steady space beats one that swings between dry and damp.
How much does piano storage cost?
Climate-controlled storage runs about $50–$150 per month (approximate 2026 US ballpark, varying by city and piano size). Piano movers that offer storage often price per piano, with grands costing more than uprights. Moving the piano in and out is billed separately.
Should I wrap a piano in plastic for storage?
Not directly. Plastic against the finish can trap moisture and may mark some finishes over time. Use breathable moving pads or a fitted cloth cover, and if you want a dust layer, put it over the pads.
Can a piano be stored on its side?
A grand is moved on its side on a skid board, but for storage it's usually best set back on its legs or kept secured on the board by a piano mover who knows how. Uprights should be stored standing upright. Ask your mover what they recommend for your piano.
Does a piano need tuning after storage?
Almost always. Give it about 2–4 weeks in its new room to acclimate, then book a tuning. Expect roughly $100–$250 in 2026, more if it has drifted far and needs a pitch raise. See piano tuning after moving.
Is it better to store a piano with a piano mover or a self-storage unit?
A piano mover's storage handles the moving in and out and is usually set up for pianos. Self-storage can work if the unit is truly climate controlled, but you still need movers to get the piano in and out. Compare both on total cost.
