The worst damage I have seen in a move never involved a dropped box. It was a mahogany side table that came off a truck in August with its veneer lifted along one edge like a page curling in the sun, and a framed watercolor that had rippled behind its glass. Nobody had touched either of them roughly. The truck had simply sat in the heat for an afternoon, and heat did the rest.
Padding protects against knocks. Only timing and a cool car protect against heat.
This is a real question in the Yakima Valley, where summer afternoons regularly climb into the 90s and a closed truck runs far hotter than the air outside. It is also a real question in winter, when the same pieces can sit in freezing temperatures on the way over a mountain pass. If you are moving antiques, art or good rugs, the season changes what you pack, what you carry yourself and how you unpack. Here is what actually gets damaged, and why.
What heat does to antique furniture
Most antique furniture is held together and finished with materials that soften when they get warm. That is the whole problem in one sentence.
Hide glue, the traditional animal glue in old joints and under veneers, loosens with heat and humidity. That is part of why restorers like it, because it can be reversed, and it is exactly why a piece can loosen in a hot truck. Veneer is the first place you see it: a lifted edge, a bubble in the middle of a panel, a crossbanding strip that springs loose. Veneer is a beautiful material and I defend it often, it gets a bad rap it doesn't deserve, but it needs to stay cool and stable.
Finishes are the second casualty. Shellac and French polish, the finishes on most good eighteenth and nineteenth century pieces, soften with heat, and a softened finish takes the imprint of whatever is pressed against it. The quilted pattern of a moving blanket can end up printed into a table top. Plastic stretch wrap is worse, because it traps heat and moisture right against the surface. Always pad first, with clean blankets or paper, and wrap over the padding, never directly on a finished surface.
Wax finishes go tacky and pick up lint. Painted furniture with an old crackled surface can lift in flakes. Gilt, which I love and want in every room, is gesso and thin leaf over wood, and it does not like heat or being rubbed. A gilt mirror frame should ride padded, upright and out of the truck if you can manage it.
What heat does to art
A stretched canvas loosens and tightens as temperature and humidity swing, and an old painting with a brittle paint layer can crack when that happens fast. Oil paint that has been dry for decades does not melt in a truck, but the varnish on top can soften and stick to anything touching it. Never let wrapping material rest on the painted face. Corner protectors and a box that keeps everything off the surface are the answer.
Works on paper under glass are the ones that ripple. Heat drives moisture out of one part of the paper and into another, and the sheet buckles inside the frame. Pastels and charcoals can shed. Photographs can stick to the glass. Anything framed behind glass should go flat or upright in a padded box, with an X of painter's tape across the glass so a crack does not turn into shards. I am a painter first, so I am particular about this, and I would put every framed piece I care about in the car with me in summer. There is more on hanging it well at the other end in a painter's guide to decorating with artwork.
The small things people forget
- Candles. They slump and fuse to each other. Pack them in a cooler with no ice.
- Vinyl records. They warp quickly in a hot vehicle. Carry them in the car, upright.
- Lacquered boxes and old plastics. They craze and soften.
- Houseplants. A closed truck in August will cook them in a few hours.
- Silk lampshades and old fabric shades. They go brittle and split.
Rugs: tough in heat, careful with moisture
Wool is the most forgiving thing you own. It handles heat well and it is far more resilient than most people think, which is one of the many reasons wool rugs are such a good choice for a home. The danger for a rug in a move is not heat on its own. It is heat and trapped moisture together. A rug rolled tight in plastic on a warm day can sweat inside its wrapping, and if it then sits for a week in a garage, it can mildew.
Roll rugs pile out, around a tube if they are large, and wrap them in breathable cloth or paper rather than sealed plastic. Never fold a hand-knotted rug along a hard crease. Silk rugs need more care than wool, because silk is weaker when wet. Unroll everything the day it arrives and let it relax flat.
Winter is a different problem, not an easier one
Cold is less dramatic than heat but it has its own failure. A wood piece that spends hours in a freezing truck and then goes straight into a heated house can pick up condensation on its surface, and a brittle old finish can check with a sudden temperature change. Paintings get brittle in the cold, so they are more likely to crack if they are flexed.
The rule is patience. Leave wrapped pieces wrapped for several hours, ideally overnight, after they come inside, so they warm up slowly inside their padding. Do not unwrap a cold mirror or a cold lacquered table and start polishing it. And if your move crosses Snoqualmie or White Pass between November and April, build in a buffer day. A closure means the truck waits somewhere cold, and your best pieces are better off waiting with you.
Plan the date around the furniture
In the Yakima Valley the most comfortable window is early fall. From mid-September to mid-October the heat eases, the smoke of late summer usually clears and the moving rush is over. If you have antiques and art, that is the season I would pick.
If summer is the only option, start at first light so loading finishes before the hottest part of the day, unload the same day, and keep a list of what rides with you in the air conditioning. If winter is the only option, drive when the passes are open and give everything time to warm up before you unwrap it. Either way, look for local and intrastate moving help from a crew that knows how Valley roads and mountain routes behave through the year, and tell them at the estimate which pieces are old, glued or gilded. The packing will be different, and they should know before they arrive.
Most damage to antiques in a move is not about impact at all. It is about temperature, and you control more of it than you think. Get that right, and the fun part is deciding where the old pieces sit against the new ones, which is the whole idea behind mixing modern and vintage.
What rides in your car
- Framed works on paper, photographs and pastels
- Small oil paintings and anything with flaking paint
- Gilt mirrors and small gilt frames, if they fit
- Candles, records and houseplants
- Anything finished in shellac that you can lift yourself
Old things look better with new things next to them, and they deserve to arrive in the new house looking the way they did in the old one.
Frequently asked questions
Can antique furniture be damaged by heat during a move?
Yes. Hide glue and veneer can loosen, and shellac or French polish finishes can soften and take the imprint of blankets or wrap. Move early in the day, pad before wrapping, and unload the same day.
Is it safe to move oil paintings in summer?
It can be, with care. Keep them out of a hot truck if possible, pack them so nothing touches the painted surface, and carry the most valuable pieces in an air-conditioned car.
How long should furniture acclimate after a winter move?
Leave wrapped pieces wrapped for several hours, ideally overnight, so they warm slowly. Unwrapping cold wood or glass in a warm room can cause condensation on the surface.
