About St Austell Bay Windows & Plastics
Nearly two decades of honest, quality double glazing installation across St Austell and the surrounding area — by a team that genuinely cares about the work we do and the people we do it for.
Our Story
St Austell Bay Windows & Plastics was founded in 2005 with a simple idea — to provide homeowners across St Austell and the surrounding area with high-quality windows, doors and conservatories, installed properly, at a fair price, by people they can trust.
Nearly twenty years later, that idea hasn't changed. We're still family-run, still based in St Austell, and still carrying out every single installation with our own in-house team. No sub-contractors, no call centres, no middlemen — just the same dedicated local team that has been serving this community since the day we opened.

Team arrived when they said they would and fitted a new front door which looks great. Hassle free from design to installation — will be using again for future planned works.
