5-Star Rated Services and Products
Windows
St Ives' granite cottages around Downalong and Barnoon often sit within conservation areas, so window replacements must respect original proportions and glazing bar patterns. We fit uPVC, aluminium, and timber-effect frames built to resist salt corrosion, suiting Victorian terraces near the harbour and newer developments around Carbis Bay and Lelant.
Roof Lanterns
Our Wendland aluminium roof lanterns bring reinforced ridges, slim sightlines, and self-cleaning glass to extensions. They suit flat-roofed extensions, flooding open-plan kitchens and living areas with coastal daylight, while creating a striking focal point.
Uni Blinds
Uni Blinds' integral blinds are sealed inside the double-glazed unit, keeping them dust-free with no tangled cords or strings. This makes them ideal for busy holiday lets and family homes across Cornwall, offering privacy without sacrificing the coastal light the region is known for.
Doors
We fit composite and aluminium doors, from bold harbourside entrances to discreet doors suited to conservation area cottages. Multi-point locking and toughened glass come as standard, while French and patio doors open living spaces onto sea views and garden terraces, perfect for homes near Porthminster Beach.
Conservatories
Conservatories must withstand strong coastal winds and salt spray, so we specify robust Wendland systems built for durability. Traditional Victorian and Edwardian styles complement heritage cottages around Barnoon, while Guardian Warmroofs convert existing conservatories into comfortable, usable rooms year-round despite the unpredictable coastal weather.

Energy Efficiency and Lower Energy Bills
A Warmer, More Comfortable Home All Year Round
Reducing heat loss is a key reason homeowners upgrade their windows. Double-glazed windows can achieve an A++ energy rating. According to the Energy Saving Trust , replacing single glazing with A-rated double glazing can save a typical semi-detached household in Great Britain around £85 a year on energy bills. Actual savings will differ depending on the home’s size, its existing windows, and how it’s heated.
Beyond thermal performance, double glazing brings other everyday benefits. It acts as a sound barrier, reducing external noise pollution from traffic, neighbours, or busy roads. This makes double glazing especially valuable for homes in noisier areas, where a quieter interior can make a real difference to day-to-day comfort. In an older property, particularly a stone cottage, well-fitted double glazing units also help reduce draughts and condensation, providing peace of mind that your home is protected against Cornwall’s coastal weather. For homes near the coast, exposure to salt air and damp conditions can take a toll on window frames over time. Marine-spec options are available to handle corrosion.
Planning Permission and Building Regulations
Do You Need Planning Permission?
St Ives town centre falls largely within a conservation area, and many properties are listed buildings, particularly around the harbour and in the older lanes. This means planning permission is more likely to be required for window and door replacements than in many other Cornish towns, especially where the property’s appearance would change.
We’d always recommend checking with Cornwall Council before work begins, and our team can advise on what’s likely to apply to your property as part of your quote. Replacement windows must also meet current Building Regulations, regardless of whether planning permission is required.
Please do not hesitate to contact us if you have any questions regarding Origin Double Glazing or the products and services we provide.
It depends on the size of your project. As trusted window installers in St Ives, we work efficiently to minimise disruption. A window typically takes 2 to 3 hours to install, meaning most homes can be completed within a day or two, depending on the number of windows being replaced. If you’re also having doors fitted or it’s a larger, whole-house job, it may take a bit longer. We’ll always confirm an estimated timeframe with you before any work begins, so you know exactly what to expect.
You’re more likely to need planning permission in many other Cornish towns, given how much of St Ives sits within a conservation area. We’d always recommend checking with Cornwall Council, and we can advise based on your specific property.
Double glazing units use two panes of glass with a sealed gap between them, rather than a single pane. This traps air or gas between the panes, dramatically improving thermal efficiency compared with old, single-glazed windows.
Yes. Double-glazed windows create a sealed barrier between two panes of glass, which significantly reduces both external noise and heat loss. This makes them a popular improvement for homes near busier roads or the seafront, where noise and weather exposure are common concerns.
Most homeowners don’t need planning permission, but this can change within St Ives’ conservation area or for listed buildings. We recommend checking with Cornwall Council and can advise based on your property.
