Homeowners considering uPVC spraying often ask whether changing the colour of their windows and doors affects performance. Kensington Windows & Conservatories is reassuring customers that professional uPVC spraying is purely a cosmetic upgrade and does not compromise functionality.

When carried out correctly, uPVC spraying leaves the structure of the window completely intact. Hinges, seals, locks and drainage channels are carefully protected during preparation, ensuring windows and doors continue to operate exactly as they should. The specialist coatings used are designed specifically for uPVC, allowing frames to expand and contract naturally with temperature changes.

Kensington’s process includes deep cleaning, surface preparation and precise application, resulting in a smooth, factory-like finish that enhances appearance without interfering with energy efficiency. In fact, many homeowners choose uPVC spraying as a way to extend the life of existing windows rather than replacing them unnecessarily.

The team also confirms that sprayed windows retain their thermal performance, weather resistance and security features. With minimal disruption and long-lasting results, uPVC spraying offers a practical way to modernise a home’s look while maintaining comfort and performance. Kensington continues to provide expert guidance to help Somerset homeowners make confident improvement decisions.
