Sash Windows in Wandsworth

Wandsworth's Timber Window Specialists

Wandsworth is home to an impressive mix of Victorian terraces, Edwardian semis, and converted riverside warehouses. The area around Wandsworth Common features particularly fine examples of late-Victorian double-fronted houses with original box sash windows, while the streets near the River Thames have undergone significant regeneration with both modern and sympathetically restored period properties. At Prime Sash Windows, we manufacture bespoke timber sash windows that honour Wandsworth's heritage while delivering modern thermal and acoustic performance.

Wandsworth Council maintains several Conservation Areas including Wandsworth Common, Old York Road, and Tonsleys. Properties within these zones require window replacements that respect the original character — typically slim meeting rails, traditional horns, and authentic glazing bar profiles. Our team has completed numerous installations in Wandsworth's Conservation Areas and understands the council's expectations.

Why Wandsworth 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 Wandsworth

Wandsworth'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.
