Sash Windows in Highgate

Highgate's Timber Window Specialists

Highgate Village retains a unique charm with its historic high street, elegant Victorian villas, and picturesque Georgian cottages. Perched on one of London's highest points with views across the city, Highgate's properties are treasured for their architectural character. At Prime Sash Windows, we manufacture bespoke timber sash windows that honour Highgate's heritage while delivering modern thermal and acoustic performance.

Highgate contains several protected Conservation Areas spanning both Haringey and Camden boroughs. Our team has experience working across both council jurisdictions, understanding the specific requirements for properties around Highgate Village, Highgate Hill, and the areas surrounding Waterlow Park and Highgate Cemetery.

Why Highgate Homeowners Choose Us

Every window is manufactured in our workshop near London from engineered Accoya or premium hardwood. Accoya is guaranteed for 50 years against rot and fungal decay — far outlasting uPVC, which typically degrades within 20 to 25 years.

• Slimline double glazing — 4/16/4 sealed units with warm-edge spacer bars. U-value 1.4 W/m²K. Part L compliant.
• PAS24 security — multi-point espagnolette locking on all opening sashes.
• Traditional lead weights — we never use spring balances. Smoother operation, longer lifespan.
• Any colour — over 2,000 RAL colours and the full Farrow & Ball range. Dual colour available.
• FENSA registered — Building Regulations self-certification and certificate on completion.

Every window is spray-finished with premium Sikkens coatings — a multi-coat system including primer, undercoat, and topcoat for a flawless, lasting finish.
