UPVC windows, doors, fascias, soffits and conservatories accumulate grime, algae, green mould and atmospheric pollution over time — turning what should be crisp and white into a dull, stained grey-green. Professional UPVC cleaning removes all of this without using abrasives or chemicals that damage the UPVC surface, restoring the original white appearance and protecting the material from further deterioration. Zenith Surface Cleaning provides professional UPVC and conservatory cleaning across Knottingley, Pontefract, Castleford and the wider West Yorkshire area.
We clean UPVC safely — using appropriate cleaning solutions that remove staining and biological growth without scratching or dulling the surface. Conservatories receive a full clean including roof panels, frames, gutters and base walls, leaving the whole structure looking fresh and well-maintained.
