"From the very outset when Will came to do the estimate, he explained the work that was needed in a clear concise manner. When the workmen came to fit the window unit, they were polite, very clean working and also resolved an issue that we had with two opening units (without being prompted). Thoroughly satisfied with the work and I would wholeheartedly recommend Pristine PVC to anyone who was thinking of having any work done on their double glazing units."

Yes! We repair!

Unlike most of our competitors we’re happy to provide a repair service and expert friendly advice on most existing conservatories, windows and doors. As our installation team also has a broad knowledge of manufacturing, it seems only sensible to provide a repair service. So if you feel you require our repair service, please contact us to see if we can help.  Here at Pristine PVC, we feel strongly that a professional honest service should be offered without question.


Pristine PVC is pleased to offer a comprehensive and competitively priced repair service. We hold over 25 years of knowledge in the VC industry which places us in an ideal position to carry out thorough investigation work to conservatory leaks, or simple replacement of a misted glazed unit. Most window and door hardware is either stocked or can be sourced in a very short time frame, usually within 24 hours. Simple door lock changes can be carried out in a matter of hours from the time you get in touch.


If in the unlikely event that we’re unable to help you, we will offer our expert advice to you, as we believe it’s important to ensure that as a company, we’ve done everything we can to help!
