Sympathetic windows & doors for listed properties in Cardiff
Flush casements, run-through horns, heritage hardware and conservation-officer-friendly quotes across the CF postcode.
Listed and conservation-area work in Cardiff is a paperwork job as much as an installation. Wrong profile and the consent falls apart; wrong glazing bar and the officer says no. Everything we quote for period stock is chosen to give the officer nothing to push back on.
Common concerns
- Consent-friendly profiles: Flush sash casements, run-through horns, mechanically-jointed corners — the details conservation officers look for on Cardiff applications.
- Slim sightlines: Aluminium and heritage uPVC profiles with sightlines down to 58mm, so the elevation reads correctly from the street.
- Timber-effect finishes: Grained foils and painted timber-look finishes that don't shout 'plastic' from the pavement.
- Documentation for the officer: We supply cross-sections, spec sheets and photo-comparison packs you can drop straight into a listed building consent application.
- Original-glazing sight matching: We match cill projection, reveal depth and bar spacing to what's already on the elevation.
- Reversible fixing where required: For grade II* properties in Cardiff, we can quote fully-reversible fixings so the frame can come out without damage.
What we prioritise
- Flush casement uPVC or aluminium: The default consent-friendly window for Cardiff period stock — no proud sash, correct shadow line.
- Run-through sash horns: For Victorian, Edwardian and Georgian openings in Cardiff where a modern sash would look wrong.
- Traditional monkey-tail furniture: Cast iron and chrome heritage handles, in place of modern D-handles.
- Slim double or heritage triple glazing: Slim units with warm-edge spacers, so U-values are modern but sightlines stay period.
- Regular installs on Grade II properties across Cardiff and the CF postcode
- Cross-section drawings supplied for every listed job
- Working relationship with conservation officers in South Wales
- Full photo record before, during and after install
Frequently Asked Questions
Can you supply drawings for our listed building consent in Cardiff?
Yes — we supply full cross-sections, elevation drawings and product spec sheets, so your architect or agent can drop them straight into the consent application.
Will you install before consent is granted?
No — for listed work in Cardiff we wait for the officer's decision in writing. We can hold your survey slot open for up to 6 months while consent is being processed.
Do you fit true timber or timber-effect?
Both. We fit engineered timber for grade I / II* jobs where required, and heritage flush-sash aluminium or uPVC for grade II and conservation-area work where the officer accepts it.
Can you match the glazing bar spacing to the original?
Yes — we photograph and template the existing bars in Cardiff and match spacing, thickness and profile in the replacement.
