Timber Sash Windows
Crafted from sustainably sourced timber, our sash windows blend traditional aesthetics with modern performance. They feature authentic detailing like glazing bars and mouldings, meeting thermal efficiency and security standards. Ideal for period properties and conservation areas, these windows offer durability, noise reduction, and a 30-year guarantee on timber.
PVCu Sash Windows
Our PVCu sash windows replicate traditional timber designs while offering low-maintenance durability. With multi-chambered profiles and advanced glazing, they provide excellent thermal efficiency and security. Available in heritage or contemporary styles, these windows are ideal for listed buildings and modern properties requiring energy-efficient solutions.
Composite Entrance Doors
Combining a solid timber core with reinforced outer skins, our composite doors offer superior security and insulation. They feature high-security locks, customizable finishes, and FSC-certified materials. Backed by a 10-year workmanship guarantee, these doors enhance curb appeal while maintaining energy efficiency and durability.
Secondary Glazing
Designed for period properties, secondary glazing improves insulation without altering original windows. Made from lightweight aluminium with acoustic glass, it reduces noise by up to 80% and enhances security. Custom-made to fit uneven frames, this solution preserves historical integrity while meeting modern performance standards.
Timber Casement Windows
These bespoke casement windows combine traditional joinery with advanced double-glazing technology. Available in flush or lipped designs, they offer enhanced security through multi-point locking systems.

Questions
Can you match original timber doors for listed buildings?
Yes, we specialize in replicating original detailing for period properties, including panelling, proportions, and traditional ironmongery to meet conservation requirements.
Do I need planning permission for window replacements?
Most replacements don't require permission, but listed buildings or conservation areas may need approval. We assist with guidance and local authority liaison.
Are dual-colour finishes available for doors?
Yes, choose different interior and exterior colours, including RAL shades, timber stains, or dual-tone options to complement your property's aesthetics.
How do I maintain my windows?
Receive a care pack with maintenance advice. Timber requires periodic repainting, while PVCu needs occasional cleaning. Annual checks preserve warranty validity.
What's the difference between timber and composite doors?
Timber offers natural aesthetics and full customization, while composite doors provide enhanced security with a timber core and low-maintenance outer skin.
Do you offer guarantees?
Yes, we provide a 10-year workmanship warranty, 30-year timber guarantee, and 10-year paint/glazing warranties across our product range.
