Frequently asked about Isleworth
Do I need planning permission for replacement windows in Isleworth?
Most window replacements in Isleworth fall under permitted development. However, the Old Isleworth and Spring Grove conservation areas have Article 4 directions that remove this right — listed buildings always require listed building consent. Check with London Borough of Hounslow planning before ordering.
Which window style suits Isleworth properties?
Isleworth has a mix of Georgian, Victorian, Edwardian housing stock. Victorian and Georgian properties typically use sliding sash or heritage casement profiles; 1930s semis suit flush casement or bay/bow windows; modern properties suit aluminium picture windows and bifold doors.
How long does a window installation take in Isleworth?
A typical 8-window installation takes 1-2 days. Bifold doors or sliding doors add another half-day each. We handle FENSA self-certification on completion so you don't need to deal with building control.
Are you FENSA registered?
Yes — Apex Glazing is FENSA registered (Reg 40373). This means we self-certify every window and door installation for Building Regulations Part L compliance without you needing separate building control inspection.
Do you cover all of TW7?
Yes, we cover every street in TW7, including all named conservation areas. We're based in Isleworth (your local area), so installation teams are on site fast.
