Before and After








UPVC and IPS panel repairs for new build and refurbishment
UPVC is everywhere on a modern site: window and door frames, cills, fascias, soffits, trims and cladding. IPS panels (integrated plumbing systems) line the back of every commercial washroom. Both get cracked, scratched, holed and chipped by the trades that follow, and both are awkward to replace once fitted. Sinclair repairs them in place.
UPVC repairs
- Cracks and holes in frames, cills, panels and trims
- Scratches, gouges and burn marks
- Drill holes and screw holes from removed fixings
- Discoloured, yellowed or faded UPVC
- Woodgrain and coloured foil finishes, repaired and colour-matched
- Full colour change by spray application: white to anthracite grey, black or any RAL colour
Cracked or holed UPVC is bonded and filled, shaped flush and refinished so the repair is lost in the surrounding surface. On foiled frames the grain is recreated. Where a frame is beyond cosmetic repair we will say so.
IPS panel and washroom repairs
IPS duct panels, WC cubicles, vanity tops and laminate wall panels in commercial and communal washrooms, in offices, schools, hotels and apartment blocks, take constant knocks from cleaning trolleys, doors and fittings. We repair chipped edges, scratched faces, cracked laminate and damaged corners, matching the laminate pattern and finish. At the Department for Education offices in London our scope for Willmott Dixon included WC cubicles, kitchens, window frames and metal ceiling grids.
Meter boxes
Cracked, smashed or faded GRP and UPVC gas and electric meter boxes are repaired and resprayed rather than replaced. See meter box repairs.
On site
UPVC and IPS repairs are booked at snagging and pre-handover, and for aftercare defects once a building is occupied. Our operatives work in finished plots and live washrooms with minimal disruption, and to the site’s induction and safety arrangements. Sinclair is CHAS accredited and Constructionline Platinum, with £10m public liability insurance.
Who we work for
Housebuilders and main contractors, fit-out contractors on commercial washrooms, facilities and aftercare teams, and homeowners with a cracked cill or damaged frame, across London, Kent and the South East.

Frequently asked questions
Can a hole in UPVC be repaired?
Yes. Holes and cracks in frames, cills and panels are bonded, filled, shaped flush and refinished to match, including woodgrain and coloured foils.
What are IPS panels?
Integrated plumbing system panels: the laminate or composite panels that box in pipework behind WCs and basins in commercial washrooms. We repair chips, scratches, cracks and damaged edges on them.
Can you repair WC cubicles?
Yes. Cubicle doors, partitions and vanity tops in laminate and solid-grade laminate are repaired and colour-matched in place.
