How to Repair a Split or Sagging Antique Drawer Bottom

Traditional drawer bottoms are often thin boards fitted into grooves and fixed at the back so they can move across the grain. A rigid repair can create new splits.

Assess the condition

Identify board orientation, grooves, slips, rear fixings and any later plywood or hardboard additions. Determine whether the bottom is split, shrunken out of its groove, bowed by overloading, or detached at the back.

Work on a clean, padded surface with good light. Photograph the object before removing any part, label components discreetly, and keep old fragments and fixings together. If the furniture is rare, signed, extensively decorated or structurally unsafe, pause and consult a furniture conservator.

Plan the repair

The best intervention addresses the cause while removing the least original material. Check adjacent joints, previous repairs, surface finish and grain direction. Rehearse assembly and clamping dry. Select tools that fit the scale of the work and use padded supports wherever pressure will be applied.

Repair method

Remove later obstructions carefully. Where possible, draw an original shrunken board forward into its front groove and add a sympathetic strip at the back rather than across the visible front. Repair clean splits with compatible adhesive and flat support. Replace missing rear fixings in their original pattern.

Use only as much adhesive or new material as the repair requires. Keep glue away from finished surfaces and clean squeeze-out promptly using a method compatible with both adhesive and finish. Clamps should close a joint, not force distorted parts into submission.

Mistakes to avoid

Do not glue the bottom along every edge; it usually needs seasonal movement. Avoid thick replacement panels that overload grooves or alter drawer capacity. Preserve inscriptions and labels on the underside.

Do not sand broadly to make a repair look new. Historic wear, tool marks and accumulated surface are part of the object. Any replacement material should be structurally sound, visually quiet and identifiable on close examination.

Finishing and testing

Support the bottom during curing, reinstall the drawer empty and load it gradually. Heavy objects should be stored elsewhere if the original bottom is thin.

Allow the repair to cure fully in stable indoor conditions. Test movement or load gradually and stop if the joint opens, the frame racks or new sounds appear.

When to call a specialist

Professional help is sensible when decoration crosses the damaged area, original finish is lifting, timber is badly shattered, evidence of insect attack is present, or earlier metal and resin repairs complicate dismantling. A conservative repair should extend useful life without pretending the object has never been repaired.
