Gelcoat is the tough, glossy outer layer on fibreglass and composite surfaces — from baths, shower trays and wet rooms to boats, hot tubs and industrial mouldings. When it chips, cracks, crazes or fades, the damage is usually cosmetic and very repairable on site. Shazam Repairs provides specialist gelcoat repair across London and the surrounding areas, restoring the finish and colour without the cost and disruption of a full replacement.
Gelcoat repair services we offer
We repair the full range of gelcoat problems: surface chips and scratches, star cracks and stress cracks, crazing and spider cracking, blistering, dull or oxidised finishes, and colour fading. Our technicians rebuild damaged areas with colour-matched gelcoat, cut back and polish the repair, and blend it into the surrounding surface so it’s invisible once finished. Whether it’s a chipped acrylic or fibreglass bath, a cracked shower tray, or a scuffed composite panel, we restore both the look and the watertight integrity of the surface. Explore our related fibreglass repair and GRP repair services for larger composite jobs.
Who we work with
We work with London homeowners, landlords, letting agents and Airbnb hosts who need a bath or shower tray back in use quickly, as well as hotels, facilities managers, boatyards and marine owners, and construction contractors handling handover snagging. If you manage rental or hospitality properties, a fast gelcoat repair keeps rooms available and avoids the expense of ripping out and replacing a perfectly sound bath or tray.
Areas we cover
We’re London-based and cover the whole capital and Greater London, along with the surrounding Home Counties and Essex. Our mobile technicians come fully equipped to complete gelcoat repairs on site, so there’s no need to remove or transport the item — ideal for fitted baths, wet rooms and moored vessels. For marine and boat work, see our dedicated marine repairs service.
Why choose Shazam Repairs
Gelcoat repair is a specialist skill — the difference between a good and a poor repair is all in the colour match, the grain of the finish and the final polish. Our technicians are experienced across domestic, hospitality and marine gelcoat, use professional colour-matching, and finish every repair to a seamless gloss. Most repairs are completed in a single visit and are ready to use the same day, with minimal mess and no need to empty the room.
Gelcoat Repair FAQs
Can gelcoat be repaired without replacing the whole bath, tray or panel?
In the large majority of cases, yes. Chips, cracks, crazing and dull patches are surface-level damage that we rebuild with colour-matched gelcoat and polish back to a seamless finish. Full replacement is usually only needed where the structure underneath is compromised — send us photos and we’ll tell you honestly which applies.
Will the repaired area match the original colour and gloss?
Yes. We colour-match the gelcoat to your existing surface and blend the repair into the surrounding area, then cut back and polish it to the same sheen. Once finished, a good gelcoat repair is very difficult to spot even close up.
How long does a gelcoat repair take and when can I use the surface again?
Most repairs are completed in a single on-site visit, often within a couple of hours, and the surface is typically ready to use the same day. Larger or multiple repairs take a little longer but are still far quicker and less disruptive than a full replacement.
