An uneven gap may result from loose runner fixings, a detached front or movement in the cabinet itself. Show neighbouring drawers as well as the fault. Adjustment is useful only when the parts and the material supporting them remain suitable.
A worn small component may be replaceable when a matching part exists and the remaining box is sound. The decision depends on condition and availability. A photo-based enquiry should not promise that discontinued hardware can be sourced or adapted.
Runner length, fixing positions and mechanism type all matter when replacement is considered. A visually similar fitting may not work with the existing box. Share labels or product records and avoid buying parts until compatibility has been checked.
The agreed service covers suitable furniture drawer fixings, fronts, compatible runners and minor non-structural joinery. Exclusions: Cabinet door hinges (existing Cabinet Repair), appliance-integrated systems, plumbing, major built-in alteration, bespoke manufacture.
