We supply and fit aluminium windows, doors and glazing repairs across Cardiff and the surrounding Cardiff area, covering CF3, CF5, CF10, CF11, CF14, CF23, CF24. Typical supplied-and-fitted cost for a standard 1200 × 1200mm casement in Cardiff is £650–£980.
Cardiff housing is dominated by Victorian bay-fronted terraces through Cathays, Roath and Canton, interwar semis in Llanishen and Rhiwbina, and a large bay-side apartment stock in Cardiff Bay where salt exposure matters. That matters, because the right window is the one that suits the stock — not the one the salesperson has in the van.
Cardiff has conservation areas including Roath Park, Cathays Park and Pontcanna. Replacing windows is permitted development for most houses, but a conservation area with an Article 4 direction removes that right, flats have no permitted development rights at all, and a listed building always needs listed building consent.
Check with Cardiff Council before you order anything. A pre-application conversation costs nothing; an enforcement notice costs a great deal. In practice, conservation officers object to thick sightlines rather than to aluminium as a material — which is exactly why a slim aluminium heritage profile is routinely accepted where uPVC is refused.
Cardiff sits close enough to salt water that the powder-coat specification genuinely matters. A standard polyester powder coat within a mile or two of the coast will begin to chalk and pit years before its guarantee expires. Specify Qualicoat Seaside grade, which uses a heavier pre-treatment developed for marine environments, and rinse the frames with fresh water a few times a year.
This is a specification issue, not an upsell. If a quote for a coastal Cardiff property does not mention marine-grade coating, ask why.
Cardiff sits in the Wales pricing band, which runs at roughly 93% the national average. These are supplied-and-fitted ranges including VAT.

Most window faults are repairs, not replacements. A misted unit is £80–£190 and keeps your existing frame. A handle is £40–£100. A dropped sash is usually a hinge, at £60–£110. And if a window is broken or a door will not lock, we treat it as an emergency — same day where a fitter is free in your CF postcode, next day everywhere else.

For most houses, no — it is permitted development. But Cardiff has conservation areas including Roath Park, Cathays Park and Pontcanna, so check with Cardiff Council before you order: a conservation area with an Article 4 direction removes permitted development rights, and a listed building always needs consent.
Yes. Broken glass, a door that will not lock, a break-in or storm damage are treated as emergencies — same day where a fitter is free in your postcode, next day everywhere else. Boarding up is £90–£180 and same-day glass replacement £120–£280.
