Sash Windows in Chiswick

Chiswick's Timber Window Specialists

Chiswick is one of West London's most elegant residential areas. The Bedford Park estate — widely regarded as the world's first garden suburb — features distinctive Queen Anne Revival houses with characterful sash windows. Along Chiswick Mall and Strand-on-the-Green, Georgian and early Victorian riverside houses retain their original timber windows. The residential streets off Chiswick High Road add a rich stock of Victorian and Edwardian homes. At Prime Sash Windows, we manufacture bespoke timber sash windows that honour Chiswick's heritage while delivering modern thermal and acoustic performance.

Hounslow Council manages several Conservation Areas in Chiswick, including Bedford Park, Strand-on-the-Green, Chiswick Mall, and Turnham Green. Bedford Park in particular requires careful attention to the distinctive Queen Anne window details — tall, multi-pane sashes with slender glazing bars. We produce windows that faithfully reproduce these period-specific profiles.

Why Chiswick 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 Chiswick

Chiswick'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.
