Sympathetic windows & doors for listed properties in Cardiff

The details conservation officers look for

• Consent-friendly profiles: Flush sash casements, run-through horns and mechanically jointed corners.
• Slim sightlines: Aluminium and heritage uPVC profiles with sightlines down to 58mm, so the elevation reads correctly.
• Timber-effect finishes: Grained foils and painted timber-look finishes that do not look like plastic from the pavement.
• Matching the original: Cill projection, reveal depth and glazing bar spacing matched to what is already on the building.
• Reversible fixings: For grade II* properties we can quote fixings that let the frame come out without damage.

Paperwork for your consent application

We provide cross-sections, specification sheets and photo-comparison packs that you can add straight to a listed building consent application, and cross-section drawings are supplied on every listed job. A full photo record is kept before, during and after the work.

We fit Grade II properties across Cardiff and the CF postcodes regularly and have a working relationship with conservation officers in South Wales, but whether a product is acceptable is always the council's decision.

Engineered timber is fitted on grade I and II* jobs where it is required, with heritage flush-sash aluminium or uPVC for grade II and conservation-area homes where the officer accepts it. Slim laminated acoustic glass can be specified in the same sightline for houses on busier roads, and heritage frames carry 10 years' cover on frame and finish, with the finish batch photographed so later colour matching is easy.

Specifications we usually suggest

• Flush casement in uPVC or aluminium: Our default for Cardiff period homes: no proud sash and the right shadow line.
• Run-through sash horns: For Victorian, Edwardian and Georgian openings where a modern sash would look out of place.
• Monkey-tail furniture: Cast iron and chrome heritage handles instead of modern D-handles.
• Slim double or heritage triple glazing: Warm-edge spacers give modern U-values while keeping period sightlines.

Booking a heritage survey

At a heritage survey we bring flush-sash samples and glazing-bar profiles, and you receive a written specification to pass to your conservation officer. The survey is free, the quote is in writing, and the 10-year guarantee and our like-for-like quote promise apply as on any other job.

Listed and period homes in Cardiff

Listed buildings need consent before windows or doors are changed, and homes in Cardiff's conservation areas, such as Pontcanna, Llandaff and parts of Roath, can face extra controls on front elevations. The first step is to check with Cardiff Council's planning team what will be acceptable on your property.

Once you know what is allowed, we can survey against the existing opening style and sightlines and tell you plainly whether one of our products is suitable. For everything else we fit across the city and the Vale, see our Cardiff and Vale of Glamorgan area page.
