Windows

Custom Glaze offers A+ energy-rated uPVC and aluminium windows, including casement, sash, and tilt-and-turn styles. These double-glazed units improve thermal efficiency, reduce noise pollution, and enhance security. Manufactured in the UK, our windows feature advanced locking systems and low-maintenance frames, ensuring durability and compliance with FENSA standards.

Conservatories

We design and install bespoke conservatories, orangeries, and extensions using Ultraframe systems. Options include Victorian, Edwardian, and lean-to styles with glass or tiled roofs. Our solutions maximise natural light, provide year-round usability, and integrate seamlessly with existing properties while meeting building regulations.

Roofline Products

Durable uPVC fascias, soffits, and guttering systems protect properties from weather damage. Available in multiple colours and profiles, these low-maintenance solutions prevent rot, resist fading, and improve thermal performance by up to 25% when combined with proper insulation.

Secondary Glazing

Slimline aluminium secondary glazing units reduce external noise by up to 80% while improving thermal efficiency. Custom-made to fit existing windows, they offer enhanced security with toughened glass and are ideal for heritage properties where original windows must remain intact.

Composite Doors

Thermally efficient composite doors combine security with aesthetic appeal. Featuring multi-point locking systems and weatherproof seals, our doors are available in various styles and colours. Installation includes precise measurements and compliance with PAS 24 security standards.

This company is a scam. 7 months and 0 work complete on our windows. Not even started production. Do not use. We are starting court proceedings and don't want other to have to deal with this company. They aren't a small family company anymore they are a family of theives

While service was good at point of fitting, follow up service during warranty wasn't the best, but happened with some chasing, after warranty do not expect ANY support even chargeable at they do not want to know! Our roof panel has blown out of place and they offer no support to resolve even with insurance company willing to pay out for it.

We ordered a front door with Custom Glaze in August this year, and put down a deposit, and were told it would be around 8 weeks to installation - since then it has been a farce, with a delayed survey, and repeated phone calls to clarify details we'd given previously. The latest, as of Nov 23 - three months after paying a deposit - is that the door we've ordered isn't possible, as the supplier no longer makes the glass we chose.

We've been advised to choose new glass, but it still likely won't be done before Christmas, the one thing we wanted when we ordered in the summer. We'd prefer to cancel, but according to CG we'd lose the deposit we paid -- on a product which they cannot provide. Appalling communication, service, and general experience.
