UPVC windows are one of the most common targets for superficial damage in UK homes — scratched during fitting, chipped from impact, yellowed with age or marked by paint splashes. The instinctive response is often to replace the affected window or frame section, but professional UPVC window repair can address the vast majority of cosmetic damage at a fraction of replacement cost. Shazam Repairs carries out professional UPVC window repair across all common damage types.
Common UPVC Window Damage Types
- Scratches — from glaziers’ tools, rings, keys or abrasive cleaning; can appear as single lines or patches of fine scratches (scuffs)
- Chips — from impact during installation, window opening/closing or external objects
- Discolouration — yellowing from UV exposure over time; chemical staining from cleaning products; paint splash or spray paint contamination
- Impact marks — dents or deformations where UPVC has been struck
- Screw and handle witness marks — recessed or raised marks around hardware locations
UPVC Scratch and Chip Repair
Scratches on UPVC frames can often be significantly reduced by careful polishing using specialist UPVC-compatible compounds that remove the damaged surface layer and restore the surrounding gloss. Deeper scratches and chips are filled with colour-matched UPVC repair compound and sanded smooth before polishing.
Colour Matching White UPVC
Most UK UPVC windows are white — but UPVC ages and yellows, which means that a standard brilliant white repair compound may look brighter than the surrounding aged frame. Our technicians tint repair materials to match the specific shade of each client’s frames, including yellowed and aged whites.
Coloured and Foiled UPVC
Anthracite grey, Chartwell green, Rosewood woodgrain and other coloured UPVC and foiled finishes are increasingly popular. Chips and scratches on these frames require tinted repair products matched to the specific colour and, for foiled finishes, attention to texture replication. We work with coloured UPVC regularly and carry products appropriate for common foiled and painted finishes.
