What Is Antique Furniture Refinishing, and When Does a Piece Need It?

A Dull Finish Usually Isn't a Failed One

A lot of antiques that look dead are just dirty. Decades of furniture polish, kitchen grease, radiator dust and hand oil build up into a dark film that sits on top of the finish, and it reads as the wood itself going bad. Finishes from the late 1800s through the 1940s also darken on their own as they age, sometimes enough to look almost opaque. None of that means the finish has to come off.

You can find out a lot on your own. Start with a soft cloth barely dampened in warm water with a drop of dish soap, work a small area on the side of the piece, and dry it right away. If the cloth comes away brown and the wood underneath looks warmer, you were looking at grime. A good paste wax, buffed out once the piece is clean and dry, often finishes the job, and the color the finish has reached over a century stays right where it is.

White rings are the other thing people bring up constantly, and in a New York apartment they're everywhere: a sweating glass, a leak from the unit upstairs, a plant pot that sat too long. A white ring is moisture trapped in the finish itself, the wood underneath is usually fine, and it tends to come out without stripping anything. Black marks are a different story, because black means the water got through the finish and into the wood, and that's a repair rather than a cleaning.

How to Tell What Finish You're Dealing With

It helps to know what's on the piece before anybody decides anything, and there's a simple test you can do at home. Find a spot nobody will ever see, like the back or the underside of a drawer, and dab it with a cotton swab dipped in denatured alcohol. If the surface softens and turns tacky within a minute, it's shellac. If nothing happens, try the same thing with lacquer thinner, and a finish that softens under that is lacquer.

Shellac was the finish on most pieces made before the twentieth century, and lacquer took over on factory furniture for much of the first half of it. That matters more than it sounds like it should. Both of them can be repaired in place, because fresh shellac or lacquer bonds with the old coat instead of sitting on top of it, so a scratch or a worn corner can be blended in without taking the whole surface back to bare wood. A piece that someone refinished in polyurethane at some point doesn't respond that way, and that's often the piece that genuinely does need stripping.

When a Piece Really Does Need Refinishing

The honest answer to the value question is that both of those people are partly right. A piece with its original finish in good or near-good shape should be left alone, because a lot of what an antique is worth sits in that surface and its patina. Strip it and you can't put a century back.

Plenty of pieces aren't in that position, though. A finish that's flaking off in sheets, one that's crazed so deep the cracks run down to the wood, a top worn through to bare wood where the hands and plates always went, or water damage that's gone black into the grain are all failed finishes, and no amount of cleaning brings them back. Same with a piece that was already refinished badly or painted over decades ago. Its value took that hit years before you owned it, and a careful refinish now is far more likely to help it than hurt it.

The other half of it is how the work gets done. A refinish in the same materials the piece was originally finished in, done by hand, sits right on an antique. A spray-on modern finish over a sanded-flat surface looks new in the wrong way, and anyone who knows furniture sees it from across the room. That's the difference between refinishing a piece and restoring an antique properly, where keeping the original surface is the whole point and refinishing is the last option rather than the first.

What Refinishing Looks Like When It's Done by Hand

When a finish does have to come off, we strip it by hand with chemical strippers. A belt sander never goes near veneer, because antique veneer is thin and a sander goes through it faster than you can lift the tool, and there's no patching a hole in a figured walnut top so it disappears. Any lifted veneer, broken molding or damaged carving gets repaired before a drop of finish goes on, since new finish over loose veneer just seals the problem in.

We match the stain to a sample you approve, so the drawer front doesn't come back a shade off from the case. Then the new finish goes on in coats, and if the piece was shellacked originally, it gets shellac again, French polish included where the piece calls for it. It's slow work, which is why a proper refinish takes as long as it does and why it costs what it does. It still comes in well under what a new piece of the same build quality would run you.

Mid-century pieces are a slightly different case, because the finish on a teak credenza or a walnut dining set is as much a part of the design as the shape. Those are twentieth-century furniture restoration jobs more often than antique ones, and a careful refinish tends to bring them back rather than cost them anything.

Getting a Straight Answer on Your Piece

Photos tell us most of what we need. Send one of the whole piece, a close shot of the worst spot taken under a lamp so the surface shows, and one of the underside or the back, which is where the original construction gives itself away. From those we can usually tell you whether the surface can be revived or needs a full strip, and that single call moves the price more than anything else about the job.

The written quote spells out the repair that makes the piece sound separately from any refinishing that makes it pretty, so you can decide on one without committing to the other. You get a timeframe before anything leaves your apartment. Pickup and delivery are available across the five boroughs, with the charge for it on the written quote. If the piece came off a moving truck with fresh damage on top of the old wear, what to do after a move is worth reading before you touch the finish at all.
