Condensation and Water Damage Under Worktops — What Can Be Repaired?

Water damage to worktops from condensation, leaks and plumbing failures is a common repair request. Here is an honest guide to what can be salvaged.

Laminate Worktops

Laminate worktops are the most vulnerable to water damage. The particle board core absorbs water rapidly and swells, causing the laminate surface to lift, bubble and delaminate.

Minor edge swelling — where only the edge has absorbed a small amount of water, drying out and edge sealing may stabilise the worktop.
Significant swelling and delamination — where the particle board has swollen substantially or the laminate has visibly lifted over a large area, replacement is usually more practical than repair.

Granite and Quartz

Natural stone and engineered quartz are non-porous. Water damage to the worktop itself is rare — but water can damage the cabinet below and the adhesive securing the sink.

Joint and seam failure from water — sealant failure at seams or around sinks allows water to pool. Re-sealing after drying.

Wooden Worktops

Solid wood worktops absorb water and swell. After thorough drying (4-8 weeks minimum), localised water damage can often be repaired and the surface re-oiled.

Getting an Assessment

Send photos and describe the water source (was it a pipe leak, overflow, sustained condensation?). We will advise honestly on what is salvageable.
