Questions buyers actually ask.
Are fibreglass doors better than composite or uPVC?
Fibreglass (GRP) resists warping, rot and rust and holds its shape across temperature swings better than timber and many uPVC doors. GemRock engineers the full construction in-house. Comparative figures: to be confirmed · placeholder
How long do GemRock fibreglass doors last?
Engineered for a long service life. Guarantee terms and expected lifespan: to be confirmed · placeholder
Do they need repainting?
No. Finishes are colour-stable and wipe-clean — no repainting cycle like timber.

Can a damaged fibreglass door be repaired?
