✓ Recommends usSuch a brilliant and professional company. So good to deal with and the windows are really special — they have transformed our seaside cottage. Thank you so much!
A renovation or refurbishment project is one of the most exciting — and most demanding — things you can do to your home. Whether you're breathing new life into a tired Cornish farmhouse, adding an extension with aluminium bi-fold doors to the rear, converting a barn into a premium living space or undertaking a complete home transformation, the windows and doors you choose will define the finished result more than almost any other element. St Austell Bay Windows & Plastics works with homeowners, self-builders and contractors across Cornwall on renovation and refurbishment projects of every scale. We supply and install the full range — from heritage flush casement windows sympathetic to period properties and conservation areas, to slim-profile aluminium bi-fold doors and sliding patio systems for contemporary extensions — all installed by our own in-house team with the same attention to detail on a single window as on a full home refit. We understand that renovation projects rarely run to a simple schedule. Our team is flexible, responsive and used to working alongside other trades — fitting around your project programme so glazing is never the thing holding everything else up.
Why Choose Us
We Work Around Your Programme
Renovation projects don't run to a fixed schedule — and we know it. Our team is flexible, used to working alongside other trades and experienced at phasing glazing installations to fit around plastering, carpentry, decoration and the unpredictable reality of a live renovation project.
Full Range — One Supplier
From heritage flush casement windows for your period front elevation to aluminium bi-fold doors on your contemporary rear extension — we supply and install everything. One surveyor, one quote, one installation team. No managing multiple glazing contractors across your project.
Coastal & Rural Properties
Every window and door we install is Certass registered, giving you full building regulation compliance and documentation. This is particularly important on renovation projects where building control sign-off is required — we handle all the certification so you don't have to.
Heritage & Conservation Specialists
Period properties, conservation areas and AONBs make up a significant part of Cornwall's housing stock. Our flush casement and sash window ranges in woodgrain and heritage finishes are sympathetic to traditional Cornish architecture and widely accepted by planning authorities. We can advise on planning requirements during your free survey.
In-House Fitters — Consistent Quality
Every installation is carried out by our own experienced in-house fitting team — never sub-contracted. That means the same high standard on the first window as the last door, full accountability throughout your project and a finish that does justice to the rest of your renovation.
We are based in St Austell and have been working across Cornwall for nearly twenty years. We know the planning conditions, the local architecture, the coastal exposure challenges and the products that work in this environment. That local knowledge is something no national glazing company can replicate.
Covering St Austell & All Surrounding Towns
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.
