Honest advice, quality products and a finish you'll be proud of.
When you invest in new windows or doors, you want complete peace of mind - and that's exactly what we deliver. Every installation carried out by St Austell Bay Windows & Plastics is backed by a 10-year guarantee as standard.
That means your frames, glazing units, locks and workmanship are all covered long after our vans have left your driveway. Your installation is also registered with FENSA for building regulation compliance.
Every installation is carried out by our own in-house team of experienced local fitters - and we never sub-contract. That means consistent quality, full accountability and a clean, tidy finish every single time.
From your free home survey through to the final fit and FENSA sign-off, we manage the entire process ourselves. Most installations are completed within a day or two, with minimal disruption to your household.
Prices for casement windows vary, depending on size, glazing specification and colour. For an accurate quote tailored to your home, contact us for a free survey.
In most cases, replacing like-for-like windows does not require planning permission. However, if your property is in a conservation area, an AONB or is a listed building, restrictions may apply. Our team can advise you on this during your free survey.
Yes. All our window and door installations are registered with FENSA, ensuring they comply with current building regulations. You receive your FENSA certificate on completion of every installation.
