Glass reinforced plastic (GRP) is everywhere in modern homes, commercial buildings and boats — from shower trays and bath panels to cladding, roofing and marine hulls. It’s tough, but it isn’t indestructible: knocks, dropped tools and everyday wear soon leave chips, cracks, scratches and dull, faded gelcoat. Our GRP repair London service restores damaged fibreglass surfaces in place, so you avoid the mess, cost and disruption of a full replacement.
GRP Repair Services We Offer
We repair the full range of GRP and fibreglass damage, colour-matched to blend seamlessly into the surrounding surface:
- Chips, cracks and impact damage to shower trays, bath panels and shower pods
- Scratches, scuffs and worn or faded gelcoat
- Star cracks, stress cracks and spider crazing
- Delamination, soft spots and localised structural reinforcement
- Gelcoat colour restoration and surface re-finishing
Whether it’s a hairline crack or a chunk knocked out of an edge, the vast majority of GRP damage can be repaired to look as good as new — without replacing the whole panel or unit.
Who We Work With
We help London homeowners, landlords and letting agents with damaged bathroom GRP, as well as hotels, facilities managers and Airbnb hosts who need fast, tidy repairs turned around between guests. We also support construction contractors and boat owners — our marine repair work covers gelcoat and hull damage on GRP vessels of all sizes.
Areas We Cover
We’re based in London and cover the capital and the surrounding Home Counties, travelling across Greater London and out into Essex, Kent, Surrey and Hertfordshire. For larger commercial, marine and construction projects we work UK-wide, coordinating around your programme and site access.
Why Choose Shazam Repairs
Our technicians specialise in on-site hard surface repair, so there’s no need to rip out or replace panels. Every repair is colour- and texture-matched, carried out with minimal mess, and usually completed in a single visit. Because we repair rather than replace, the finish stays discreet and the surrounding area is left untouched. We also carry out closely related fibreglass repair work across baths, shower trays and moulded panels.
GRP Repair FAQs
Can a cracked GRP shower tray be repaired instead of replaced?
In most cases, yes. Cracks, chips and soft spots in GRP shower trays can be filled, reinforced and re-finished in place, so there’s no need to rip out the tray or disturb the tiling around it. The repaired area is colour-matched to blend in with the rest of the tray.
How long does a GRP repair usually take?
Most domestic GRP repairs — a chipped bath panel, a cracked shower tray or a scratched cladding panel — are completed in a single visit, often within a few hours. Larger or structural jobs, such as marine hull or roofing work, may need a return visit so each layer can cure fully. We’ll confirm the likely timescale once we’ve assessed the damage.
Will the repair match the colour and finish of my existing GRP?
Yes. We colour- and texture-match every repair to the surrounding gelcoat, including the gloss level, so the fixed area blends in rather than standing out. If you’re not sure whether a particular mark can be made invisible, send us a photo and we’ll tell you honestly what result to expect.
