Fitting heritage steel window replacement in Swansea and Neath
Around Swansea and Mumbles we see coastal homes and Victorian terraces, where external steel doors open onto sea-facing gardens.
Our team handles survey, drawings, fabrication and fitting, so you deal with one contact from start to finish. Safety glass is standard in every internal pane, and we check whether fire-rated glazing is needed before anything is ordered.
We cover Swansea, Mumbles, Neath and Llanelli, plus the villages and towns between them. Lead time is 5–7 weeks from signed-off drawings, and we confirm dates in writing when you sign off the drawings.
What we can include
- Heritage-profile steel sections matched to the original
- Curved and corner bay windows
- Galvanised and powder coated in period colours
- Drawings to support listed building or Article 4 applications
Heritage steel window replacement means removing failing original metal windows, typically from the 1920s to 1950s, and fitting new steel windows that copy their slim sections, glazing-bar patterns and opening lights. Read the full guide to heritage steel window replacement.
