Can a leaking balcony be repaired without replacing everything?

Often, if the fault is at an outlet, edge or fixing and the deck is sound. We check before recommending anything bigger.

What surface can go on top?

GRP and liquid systems can take a non-slip finish directly. Tiles or decking can be laid over a suitable waterproofing layer if you prefer that look.

Balcony & Roof Terrace Repairs

A balcony or roof terrace over a living space is really a flat roof you walk on, with extra details that make it harder to keep watertight: a door threshold, balustrade fixings, tiles or decking on top, and drainage that has to cope with heavy rain.

We repair and re-waterproof balconies and terraces on houses and flats, tracing the leak to its source and using seamless GRP or liquid-applied systems with a non-slip finish.

Repair or replace?

If the leak traces to one detail and the deck is dry and sound, a local repair is often enough. If leaks keep returning, the deck is soft, or water ponds across the surface, full re-waterproofing with corrected falls is usually the better long-term answer.
