Casement windows for N20 homes
Rear extensions and back additions on Victorian terraces often suit casements, and choosing a flush or storm style lets you balance a traditional look against budget.
Many 1930s semis originally had leaded or stained-glass top lights, and we can incorporate decorative glass or Georgian bars into casements to keep that look. Where a conservation area expects slim traditional joinery, a flush casement with putty-style beads looks closer to the original than a standard storm casement.
Larger homes need big glazed doors and good security, while older houses near the High Road need period-appropriate replacements. The High Road and the Northern line are the main sources of noise. We are about six miles from N20.
Casement windows are hinged at the side or top and open outwards, making them the most common window style in British homes. We make them to measure in uPVC and aluminium, and they suit almost any property, from terraces and semis to flats and modern houses.
- Side or top hung to suit each opening
- Opens wide for ventilation and cleaning
- Escape hinges available for upper floors
Questions from N20
Do I need planning permission for casement windows in N20?
Like-for-like casement replacement on a house is normally permitted development, and our FENSA registration handles Building Regulations compliance, though flats, listed buildings and Article 4 areas can need extra consent.
How soon can you fit casement windows in N20?
Lead times vary by product and workload — confirmed with your quote. Being about 6.0 miles from our factory makes surveys, fitting days and aftercare visits easy to arrange.
Are outward-opening casements secure?
Modern casements use multi-point locking, internally beaded glazing and secure hinges, so they are far harder to force than older windows. Lockable handles add another layer of security, and restrictors let you leave windows slightly open for ventilation while limiting how far they open.
Can I see samples before I decide?
Yes. Our showroom is at Unit G, 1 Anthony Way, London N18 3QT (Mon–Fri 8am–5pm), about 6.0 miles from N20. We can also bring samples to your home in N20 at the free survey.
