We supply and fit aluminium windows, doors and glazing repairs across St Albans and the surrounding Hertfordshire area, covering AL1–AL4. Typical supplied-and-fitted cost for a standard 1200 × 1200mm casement in St Albans is £740–£1,100.
St Albans housing is dominated by a protected historic core, Victorian and Edwardian villas around Fishpool Street and Marlborough, and a large premium interwar semi and detached stock. That matters, because the right window is the one that suits the stock — not the one the salesperson has in the van.
St Albans has a heavily protected medieval and Georgian centre where window replacement is often subject to conservation-area consent. 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 St Albans City and District 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.
St Albans sits in the East of England pricing band, which runs at roughly 105% 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 AL postcode, next day everywhere else.

For most houses, no — it is permitted development. But St Albans has a heavily protected medieval and Georgian centre where window replacement is often subject to conservation-area consent, so check with St Albans City and District 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.
