Kitchen Unit Repair: Fix Hinges, Drawers & Cabinets
Daily use, heavy cookware, and general wear and tear inevitably take their toll on kitchen cabinetry. Loose doors, sticking drawers, and damaged carcass panels do not mean you have to rip out the entire room. With the right replacement hardware and a few basic joinery techniques, successful kitchen unit repair is straightforward, cost-effective, and extends the life of your existing cabinets by years.
Fixing Torn-Out Cabinet Hinges
The most frequent issue with kitchen carcasses is screws pulling out of chipboard or MDF side walls. Standard 35 mm concealed hinges exert significant leverage on cabinet walls, which easily strips the wood fibres if a door is forced.
- Hinge Repair Plates: Stainless steel hinge repair plates are the cleanest, most reliable solution. These pre-drilled brackets sandwich the damaged carcass wall, distributing the load across multiple fresh screw locations while securing the mounting plate firmly in its original position.
- Wooden Dowels and Wood Glue: If the damage is isolated to a single screw hole, drill out the damaged area to 6 mm or 8 mm, tap in a glued wooden dowel flush with the surface, let it cure, and pre-drill a new pilot hole.
- Euro Screws vs Wood Screws: For standard 32 mm system holes (5 mm diameter), use wide-thread Euro screws instead of traditional wood screws to gain maximum purchase into the core material.
Remedying Sagging or Sticking Drawers
Drawers tend to fail either because the internal slide mechanism is worn or the drawer bottom has bowed and slipped out of its rebate.
Replacing Drawer Runners
Worn ball-bearing or bottom-fix roller runners cause drawers to drop, rub against the carcass, or jam. When undertaking kitchen unit repair on drawers, measure the depth of your cabinet (typically 250 mm to 550 mm) and the side clearance. Standard roller slides generally require a 12.5 mm gap on each side, whereas undermount runners have specific box dimension requirements. Upgrading tired runners to soft-close ball-bearing models restores smooth, reliable movement instantly.
Reinforcing Bowed Drawer Bases
Heavy contents can cause thin 3 mm hardboard bottoms to drop. Fit small triangular drawer base repair brackets under the bottom panel, screwing them into both the drawer back/front and the baseboard to pull the panel flat and lock it back into its groove.
Stabilising Loose Cabinets and Plinth Legs
Base units can shift over time if the original fixings fail or floor levels settle.
- Cabinet Connecting Bolts: If individual carcasses are drifting apart, clamp the face frames or side panels flush and secure them using steel connector bolts (M4 or M6 sleeve fixings) through existing shelf pin holes.
- Adjustable Base Legs: Broken plastic plinth legs cause counter drops and misaligned worktops. Replace damaged feet with heavy-duty adjustable cabinet legs. Adjust the height using the threaded base to ensure the carcass sits completely level before reattaching the kickboard with plinth clips.
