A loose table joint does not always require the whole table to be taken apart. If the surrounding wood is sound and the movement is confined to one mortise-and-tenon or dowelled connection, the joint can often be cleaned, glued, and clamped in place.
The important word is often. A repair made without understanding where the movement comes from may trap the table out of square, conceal a split, or leave old adhesive between surfaces that need to bond. Begin with diagnosis, and dismantle only as much as the fault requires.
First find the source of the movement
Turn the table over onto a padded surface, using another person to help with a heavy or awkward piece. Protect the top from grit and pressure. Do not lift the table by a loose leg.
Rock the table gently and watch the joints rather than the tabletop. Place one hand across a suspect joint and move the table with the other. Feeling a small gap open and close can reveal movement that is difficult to see. Check each leg, the rails joining the legs, corner blocks, screws, and stretchers. A wobble may come from a loose joint, but it may also come from an uneven foot or a damaged fastening.
Mark the loose connection with a pencil on an inconspicuous surface. If more than one joint moves, identify whether they are related. A table may have loosened because it was lifted by its top, dragged across a floor, or subjected to repeated racking. Repairing one visible joint will not cure a frame that is loose throughout.
Look closely for warning signs:
- a split running through the leg, rail, tenon, or dowel;
- a crushed or missing shoulder on a tenon;
- a joint that has pulled apart so far that the wood fibres are damaged;
- a cracked corner block or loose screw hole;
- movement that comes from the tabletop itself rather than the frame.
If any of these are present, an in-place glue repair may be temporary or unsuitable. A structural split should be stabilised before the joint is closed, and a badly damaged connection may need partial or complete disassembly.

Decide whether the joint can be repaired in place
A joint is a good candidate for an in-place repair when it opens slightly but still returns to its original position, its components remain aligned, and there is enough access to introduce adhesive. The table should also be stable enough to clamp without forcing the frame into a new shape.
A mortise-and-tenon joint may show a gap at the shoulder where the rail meets the leg. A dowelled joint may move with a faint creak while the outside faces remain close together. In either case, do not widen the joint simply to make it easier to fill. Removing sound wood reduces the surface available for a proper bond.
Full disassembly is the safer course when the joint cannot be brought back into alignment by hand, when old adhesive has formed hard ridges deep inside the joint, or when several connected joints are loose. It is also preferable for valuable, heavily finished, or structurally damaged furniture where a hidden fault must be examined rather than sealed over.
Prepare the joint and the work area
Remove loose dirt with a dry brush. Put protective paper beneath the work and around the joint, particularly if the table has a porous finish. Have clamps, wooden pads, wedges, adhesive, a small brush or syringe, and a damp cloth ready before applying anything.
If the joint opens enough to admit a thin tool, work away only the accessible, friable adhesive. A narrow scraper, blunt blade, or small pick can lift flakes from the mouth of a joint. Take care not to score the tenon, enlarge the mortise, or break the edges of a dowel hole.
Old animal hide glue may soften with gentle moisture and warmth, but water should be used sparingly. Do not soak a finished surface or flood a joint that contains veneer. Modern cured adhesives may not soften in the same way, and aggressive scraping or heat can do more harm than the adhesive. The aim is to remove loose residue and expose sound wood, not to make the joint look new.
Dry-fit the joint before gluing. Push it together by hand and check that the table frame returns to its proper shape. If a clamp is needed even for the dry fit, position it now and make sure its pads bear on strong areas. Use wooden wedges or shims to close a gap only where they will not crush the edge of the leg or rail.
Choose an adhesive with the furniture in mind
For older furniture, traditional hide glue is often a sensible choice where it can be introduced into the joint and where later repairability matters. It is compatible with many old hide-glue repairs and can be softened during future conservation work. It must, however, be used in a form and at a temperature appropriate to the product, with the joint assembled promptly while the adhesive remains workable.
A suitable modern furniture adhesive may be appropriate for clean, dry wood and a sound joint. Follow its instructions for open time, clamping, and cleaning. Do not assume that any adhesive will bond reliably over a hard, glossy layer of unknown old glue. If the old adhesive cannot be removed and is not compatible with the new one, a complete dismantling may be necessary.
Avoid filling a loose structural joint with a large quantity of expanding or brittle adhesive simply because it is difficult to reach. Such products can force the joint apart, obscure future repairs, or leave a hard mass around moving wood. Adhesive should join sound mating surfaces, not compensate for missing timber.
Work the adhesive into the joint
Open the joint only as far as it naturally permits. A wooden wedge can hold a small opening without marking the finished wood; wrap its contact area if necessary. Apply adhesive along the accessible seam with a small brush, syringe, or narrow nozzle. Move the leg or rail gently through its normal range so the adhesive is drawn farther into the joint. Do not lever against a thin rail or a fragile leg.
For a dowelled joint, place adhesive around the visible entry of the dowel and along the open seam rather than forcing a large amount into one point. For a mortise-and-tenon joint, work adhesive into both sides of the opening if they can be reached. Gravity may help: orient the table so the adhesive travels into the joint, but keep it controlled and away from finished faces.
A small amount of squeeze-out at the seam is useful evidence that adhesive has reached the joint. Excess adhesive is not proof of a better repair. Wipe it away with a lightly damp cloth before it dries, taking care not to spread it across the grain or into an open-pored finish.

Close and clamp the frame accurately
Bring the joint together by hand first. Check the table from several directions. The leg should sit at the same angle as its opposite or neighbouring legs, and the rails should meet without being twisted. If the joint resists closing, release the pressure and investigate. Tightening a clamp against a hidden obstruction can split a rail or force the frame out of square.
Use clamps with wooden pads or thick protective layers between the metal and the table. Place the pressure in line with the joint wherever possible. Tighten gradually, alternating between clamps if more than one is needed. The goal is firm contact, not maximum force. A clamp that bows a rail or leaves deep pad marks is too tight or badly positioned.
Wedges can help keep a leg in its original orientation while the adhesive sets, but they should not be driven hard into a gap. If the table has several loose joints, clamp the frame in its natural alignment rather than pulling every joint closed independently.
Leave the clamps in place for the period required by the adhesive. Keep the table undisturbed during this time and avoid testing the joint early. Hide glue and many modern adhesives have different working and curing behaviour; follow the instructions for the product being used, allowing longer when the room is cool or the joint is enclosed.
After the repair has set
Remove the clamps carefully and inspect the seam. Scrape away any dry squeeze-out with a blunt tool rather than cutting into the finish. Check that the table stands evenly and that the repaired joint no longer shifts under gentle hand pressure.
Return the table to service gradually. Do not drag it by one leg, lift it by the tabletop if the frame is delicate, or load it heavily before the adhesive has fully cured. Felt pads or a level floor may correct a minor wobble that is separate from the repaired joint, but they should not be used to disguise continuing structural movement.
If the joint loosens again, stop adding adhesive. Repeated gluing from the outside usually leaves a layered, contaminated joint and makes the eventual repair harder. At that point, remove the necessary rails or leg, clean the joint fully, repair damaged timber, and rebuild the connection with proper access.

Mistakes worth avoiding
Do not glue before finding the moving part
A loose screw, cracked block, or uneven foot can imitate a failed joint. Confirm the movement with your hand before preparing the adhesive.
Do not force a joint into square
The old position is the guide. If the frame will not return there freely, something may be broken, swollen, or obstructed.
Do not flood finished wood
Adhesive and excess moisture can mark a surface permanently, especially on open-grained timber or an old shellac finish.
Do not rely on adhesive to replace wood
Missing shoulders, crushed tenons, and split legs need timber repair or replacement, not a larger dose of glue.
A quiet, well-aligned repair is usually the best one. When the joint is sound enough to close naturally, careful cleaning, controlled adhesive, and moderate clamping can restore a table without disturbing the rest of its frame. When it cannot, taking the joint apart is not a failure of the method; it is the point at which sound repair requires proper access.
