The features and benefits of our Heritage doors

Designed for authenticity

Exact period replication: We match original mouldings, beading, and panel profiles to reflect the architectural style of your property.

True-to-era proportions: Slim glazing bars and true divided lights can be added where appropriate, preserving the visual balance of traditional doors.

Time-honoured joinery: All doors are built with traditional mortice-and-tenon joints for strength, stability, and heritage authenticity.

Made with modern performance in mind

Insulation and draught-proofing: Our doors are made with multi-layer weather seals and precision-engineered timber frames that minimise heat loss and eliminate unwanted draughts.

Security: We offer Secured by Design multi-point locking systems and the option of toughened or laminated glazing provide enhanced protection without altering the traditional look.

Glazing Performance: You or your client can choose from slimline double glazing for listed properties, low-E glass to reduce energy bills, or acoustic glazing for quieter interiors.

A bespoke approach with exceptional craftsmanship

We begin with a detailed design consultation, taking the time to understand your project’s goals, review the property style, and ensure we’re working, where needed, following the needs of architects and planning officers. This ensures compliance with Heritage restrictions and planning guidelines, particularly for listed buildings and conservation areas.

Your door is then tailored with a full range of customisation options:

Timber species: These are all sustainably sourced, FSC-certified woods chosen for beauty, strength, and longevity.
Glazing types: This may be anything from slimline double glazing for listed buildings to decorative glass or energy-efficient low-E options.
Paint and stain finishes: We have a curated palette of fitting colours and natural stains.
Hardware styles: These range from period-accurate handles and hinges to more contemporary choices for modern Heritage-inspired homes.

Exceptional craftsmanship

Every door is hand-finished by our skilled Cornish joiners, who bring decades of experience in heritage projects. Each timber section is carefully sanded, primed, and coated for a flawless finish, with precision manufacturing to ensure a perfect fit for the property’s unique measurements.
