15+ years’ experience

Here at Kolorseal, we started out colour coating PVC-U window frames, doors and conservatories back in 2004, meaning we’ve had a long time to refine our spraying processes.

Today, we work from 5 purpose built colour coating booths – we can also  provide spray coatings for windows and doors on-site. We offer bespoke colour coating for a wide range of upvc windows, doors, composite doors, rooflines and rainwater goods. We can also colour coat aluminium and glass products.  When we say any colour in 5 days, we mean it.

Our Kolorseal Coatings

We’ve spent years developing our colour coating process and techniques, which are nationally recognised for their quality and hardwearing properties. Whether you’re looking for a colour coating for your windows, doors, composite doors or roofline, you can enjoy reassurance from maximum adhesion and excellent value.

The quality of our coatings has allowed to us to build a reputation for quality that is second to none, as demonstrated by achieving industry Colour Coating Specialists awards for 4 consecutive years.

Our Process

Whilst the quality of the coating is essential correct application is vital on any colour coated product.

Working from our 5 enclosed colour coating booths, we apply premium coatings in a controlled environment to ensure each finish is contamination free. We perform extensive quality control checks before products are protected and wrapped.

“Kolorseal offer a fantastic service and are a pleasure to deal with. The turnaround time of our quotes is especially impressive, which enables us to close sales more effectively” Also on another matter, we have a lady who has had a Composite Door installed and she is really unhappy with the colour of the outer frame (nothing to do with you) Are you able to offer a spray service for installed products ? I know a few companies have sprung up offering this, but would rather use you.
