IN SHORT
Replace just the doors, drawer fronts and hardware when the box behind them is still firm, dry and square, because everything you see hangs on that box. Replace the whole cabinet when the base panel is soft, the side panels have swollen, hinge screws no longer hold, termites have damaged the board or the layout itself no longer suits you.
Kitchen cabinet renovation cost depends on a decision you can make before anyone quotes: is the box behind the doors worth keeping? New doors and handles change how the kitchen looks, but they hang on the old structure, so a weak box carries its problems into the new front. This guide shows how to test the box with a torch and a screwdriver, what a door-and-hardware refresh does and does not fix, and what to ask for if you decide to replace the whole cabinet.
Think of a kitchen cabinet as three layers. The outer layer is what you see: door fronts, drawer fronts and handles. The middle layer is what you touch every day: hinges and drawer runners. The inner layer carries the load: the box, also called the carcass, with the worktop resting on its top edge. A door-and-hardware refresh renews the first two layers. Replacing the whole cabinet renews all three. So the choice is less about doors versus cabinet and more about whether the inner layer is still doing its job. In a humid Malaysian kitchen, where steam and washing-up add moisture, it is the layer you do not see failing. That is why the box check comes before the quotation. If the box passes, a refresh keeps what already works. If it fails, new fronts hide the problem for a while and the spending goes onto a structure that is already giving way.
Start with the sink base, because a trap or hose can drip behind a closed door unnoticed. Empty the unit, run a torch along the base panel and the lower part of the side panels, and press a thumb into the board. Sound board feels firm. A spongy patch, a crumbling edge or a dark stain spreading from a pipe hole suggests water has got into the board. Next, crouch down to the bottom edge of the other base units, where mop water collects, and look for edge banding lifting over a puffy core. Then test the fixings: tighten a hinge screw, and if it spins without biting, the board around it may have broken down. Rest a hand on a loaded shelf and look for a dip, and check whether the doors still line up evenly along the run. Work through every unit, not just the worst-looking one.
Read each flaw by where it sits, because not every mark means the box is finished. A scuffed face, a chipped corner or a faded door skin is a surface matter and says nothing about strength. Edge banding that has lifted over firm board is a smaller problem than banding lifting over board that has puffed up. Swelling is the serious sign: a panel whose core has swollen from water has lost strength, so treat it as damage, not a blemish. Plywood's crossed layers reduce thickness swelling, yet no board likes standing water, so a plywood base panel that has sat wet deserves the same suspicion. A longer screw may hold a hinge in a sound side panel, but in a soft one it has crumbs to grip. Hollow-sounding board, fine powder or mud lines at the back can point to termites, and our guide to moisture and termites in Malaysian cabinets shows what to look for.
A refresh is enough when the box passes every check and the layout still suits the way you cook. It solves problems on the outer two layers: door skins that have peeled or faded, drawer fronts that no longer match, hinges that sag, runners that stick and handles that have worn. Check the hinges and door edges before you decide. New fronts are cut to the openings of the box that stays, so have the carpenter measure the existing openings and confirm the hinge positions before anything is ordered. A new worktop calls for a second inspection: the old top comes off, which exposes the top edge of each base unit, so check that it is firm and level before the new top goes down. Our comparison of melamine, laminate and acrylic doors helps with the finish choice. What a refresh does not touch is the plan, meaning where the sink, hob and tall units sit.
Replace the whole cabinet when the box has failed, when the plan no longer works, or when the box is all that remains of the old kitchen. A box has failed when the base panel under the sink is soft, the sides have swollen, termites have damaged the board or hinge screws will not hold. Base units are joined to one another and carry one worktop, so a bad box can disturb its neighbours when it comes out; look at the whole run together before patching a single unit. A plan that no longer works is a reason in itself: moving the sink or hob, fitting a larger appliance or separating a wet and dry kitchen all change the box sizes and cut-outs. Where new doors, hardware and a worktop are all going in anyway, ask what the old box still contributes. If the answer is little, replacing the run lets you choose the board, which is the next question.
Ask for the box to be named on the quotation, not just the door colour, because it has to live with Malaysian humidity. Which board is it: plywood, particleboard or fibreboard? What thickness are the sides, base, shelves and back panel, and how are the cut edges and the sink cut-out sealed? Then ask for the formaldehyde emission grade and the test report behind it. Under GB/T 39600-2021, measured in a 1m³ climate chamber, ENF is 0.025 mg/m³ or below, E0 is 0.050 or below and E1 is 0.124 or below. Check whether the report covers the board you are being sold or a sample submitted for testing. Ask which lines would change if the board were swapped, because a quotation that just says 'melamine cabinet' hides that. Finally, ask what the warranty covers on the box. With those answers on paper, you can compare two quotations box against box instead of door against door.
What goes into a kitchen cabinet renovation cost?
The cost follows the scope, so it helps to list what is replaced and what is kept: hardware, doors and drawer fronts, the worktop or the boxes themselves. If the boxes are replaced, the board, its thickness and the edge sealing matter, as do the finish, the number of units and the removal and refitting around the sink and appliances. We do not publish figures here. Put each of these on its own line so two quotations can be compared line by line.
Is it worth buying used kitchen cabinets instead of replacing mine?
Used cabinets are worth considering if each box passes the checks above: firm base panels, no swollen edges, hinge screws that bite and no sign of termites. They were cut for someone else's room, so measure your wall lengths and the positions of the sink, hob and appliances against them before you pay. Look at the back and the underside as well as the doors, because a clean front says little about the box. Ask how the units were taken off the wall, since removal can damage the fixings.
What if just the unit under the sink is damaged?
A single unit can be replaced if its neighbours pass the same checks. Water can travel along a panel, so inspect the side panels of the units on either side and the underside of the worktop above before you decide. The new box has to meet the old run at the same height and under the same worktop, and its door has to match the rest of the run, which is simpler when the other doors are being replaced too. If the neighbouring units also show soft board, treat it as a whole-run decision.
What does JIYU do if the old cabinet has to be replaced?
JIYU builds new built-in cabinetry such as kitchen cabinets and wardrobes, so this applies once you have decided the old box should go. The steps are free on-site measuring, a free 3D drawing for homeowners who are seriously considering us, and an itemised quotation that you confirm before signing. The cabinets are then made to your measurements from our ENF-grade plywood (ENF is 0.025 mg/m³ or below under GB/T 39600-2021) and installed by our own team. Our submitted sample measured 0.022 mg/m³ in report JC26-WT0087; the report covers that sample, not every sheet. Plumbing, electrical work and ceilings are subcontracted, and we are not a general renovation contractor.
