Vintage furniture shopping rewards the careful eye. A piece can look immaculate on the surface and still carry hidden problems underneath a fresh coat of paint or a newly sanded top. Whether you're browsing at an estate sale, an op shop, or a weekend market, knowing how to tell if vintage furniture has been refinished or restored changes what you pay, what you pass on, and what you take home.
Why it matters whether a piece has been refinished
Refinishing isn't automatically bad. A well-done restoration can preserve a structurally sound piece for another century. The problem is that poor refinishing strips original patina, fills joinery gaps with filler, or covers serious damage with a coat of paint. It can also reduce the value of genuinely collectible pieces. An original-finish mid century modern furniture piece is worth considerably more to a serious collector than the same design freshly lacquered.
The other concern is transparency. Some sellers present heavily restored pieces as "original condition" because they genuinely don't know better. Others know exactly what they're doing. Either way, you're the one making the buying decision, so the knowledge sits with you.
Signs a piece has been repainted or refinished
Start with light. Take the piece to a doorway or step outside if you can. Raking light at a low angle across a flat surface reveals brush marks, roller texture, drips, and uneven coverage that's invisible under overhead shop lighting. A factory-original finish on most pre-1970s furniture is either lacquer-thin shellac or a hand-rubbed oil, both of which sit flat. A repainted surface often shows a slight texture, even with a high-quality brush.
Check the edges and recesses next. Paint builds up in corners. Open a drawer and look at the interior edge of the frame where it meets the drawer face. A refinished exterior often leaves a visible paint line or a slightly different colour where the original finish survived. The inside of legs, the back panels, and the undersides of shelves are good reference points. These are the spots most refinishers don't bother with, so they hold the original colour and sheen.
Hardware tells a story too. Remove a knob or pull and look at the ghost left behind. If the surrounding timber is a different shade, the hardware was on the piece when it was painted over, which means someone masked it badly or the refinishing predates the current hardware. Screw holes that don't quite line up with the existing fittings suggest hardware was swapped after a repaint.
How to spot a stripped or re-stained surface
Stripping old stain or shellac is messier work than painting, and it leaves its own evidence. Look for grain raising: when timber gets wet from a stripper or water-based stain, the fibres swell slightly and stand up. A refinisher who doesn't sand properly between coats leaves a slightly rough surface you can feel with your fingertips even when it looks smooth to the eye.
Colour consistency is another tell. Old timber develops uneven tones over decades, darker where hands touched it, lighter where sunlight hit. A re-stained piece often has a flat, even colour that looks uniform in a way real aged timber doesn't. Run your eye along the grain. Natural aged timber has tonal variation. Freshly stained timber tends to look like a single wash of colour.
The underside is your best friend here. Flip the piece, or crouch and look underneath a tabletop. The underside of a genuinely old piece will have a dusty, silvery patina that takes decades to form. If the top has been stripped and re-stained but the underside hasn't been touched, the colour difference is immediately visible.
Checking for structural repairs and filler
Paint hides more than colour. It hides filler, cracked joints, replaced timber sections, and woodworm damage that's been treated and sealed over. Press along joints with your thumb. A solid mortise-and-tenon joint doesn't flex. A glued or filled repair often has a slightly different give, particularly in older pieces where the filler has dried and contracted slightly from the surrounding wood.
Look at the dovetails on drawer corners. Original hand-cut dovetails from pre-industrial pieces are slightly irregular, each pin a fraction different from the last. Machine-cut dovetails are perfectly even. If a piece is presented as 19th century but has ruler-perfect dovetails, that's a reproduction or a replaced drawer. It's not necessarily a problem, but it should factor into what you pay.
Woodworm holes are common in older European and older Australian furniture. If you see a cluster of holes on one surface but not the surrounding timber, and those holes are clean rather than dusty, the worm has likely been treated and the surface refinished. That's fine. But it does tell you the piece had a problem at some point, and it's worth confirming the treatment is old rather than fresh.
When restoration adds value rather than subtracting it
A skilled furniture restorer working with original materials and period-appropriate techniques can increase a piece's longevity without compromising its character. The distinction is between restoration (repairing what's broken while preserving what's original) and refinishing (stripping and recoating the entire surface). The first is often desirable. The second is a matter of degree.
If you're shopping for decorative pieces rather than collectibles, a cleanly refinished item is a perfectly sound choice. It's already done the work of looking good, and you won't have the restoration costs ahead of you. The key is paying a price that reflects the restoration rather than paying original-condition prices for a piece that isn't. If you want to understand what to look for in terms of underlying value and collectibility, the most valuable vintage home decor items are generally those where original finish and hardware are intact.
Practical questions to ask the seller
Ask directly. Most honest sellers will tell you immediately if they refinished a piece themselves or bought it that way. The ones who hedge or change the subject are usually signalling something. Specific questions work better than general ones. "Has this been repainted?" gets a clearer answer than "Is it original?" because it's harder to dodge.
Ask about the provenance too. Where did the piece come from? How long has the seller had it? A piece that came from a deceased estate via a house clearance is more likely to be genuinely aged than one bought from a furniture restorer at a market. Neither is a guarantee, but provenance narrows your uncertainty.
If you're considering a significant purchase, bring a small UV torch. Some synthetic fillers and modern lacquers fluoresce under UV in a way that older shellac and wax finishes don't. It's not a perfect test, but it's a quick one that can confirm or challenge what your eyes are already telling you.
The ability to read what a piece has been through matters at every level of vintage collecting. Whether you're hunting for a single statement sideboard or starting a vintage collection on a budget, taking an extra five minutes to examine the underside, check the joints, and ask the right questions is what separates a considered buy from a disappointing one.
