Sash Windows in Notting Hill

Notting Hill's Timber Window Specialists

Notting Hill is defined by its iconic stucco-fronted Victorian townhouses and grand communal garden squares. The pastel-painted façades of Portobello Road and the white stucco crescents of Ladbroke Grove are among London's most photographed streetscapes. These properties feature tall, elegant sash windows — typically six-over-six or two-over-two designs — that are integral to the area's architectural identity. At Prime Sash Windows, we manufacture bespoke timber sash windows that honour Notting Hill's heritage while delivering modern thermal and acoustic performance.

Most of Notting Hill falls within the Ladbroke Conservation Area, one of London's largest and most strictly controlled. The Royal Borough of Kensington and Chelsea requires replacement windows to match original designs in every detail — from glazing bar thickness to horn profiles and putty-line sightlines. We have extensive experience manufacturing windows for RBKC properties and understand the specific requirements that conservation officers expect.

Why Notting Hill 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 and cannot be repaired.

• 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.
• 4–5 week delivery — manufactured in our UK workshop, not imported. Standard configurations delivered in 4–5 weeks.
• 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.

Conservation Areas in Notting Hill

Notting Hill's Conservation Areas require careful attention to original window details. Listed buildings and protected properties need like-for-like replacements with specific glazing bar profiles, horn details, and putty-line sightlines. We produce windows with authentic slim meeting rails, ovolo or chamfer beading profiles, and run-through horns that match original period detailing.

We handle the paperwork too. Where planning permission is required, we supply detailed drawings and specifications. For most replacements in non-listed properties, our FENSA registration means no separate Building Control application is needed.

What We Offer

• Box sash windows — traditional double-hung sash windows with cords and lead weights.
• Casement windows — flush casement and stormproof designs for Arts and Crafts and modern properties.
• Slim Georgian bars — authentic planted or run-through glazing bars.
• Arched and shaped windows — gothic, segmental, and true-arch heads.
• Secondary glazing — for Listed buildings where external changes are restricted.
