Sash Windows in Winchester

Winchester's Timber Window Specialists

Winchester is a historic cathedral city with a wealth of Georgian and Regency townhouses, particularly around the Cathedral Close, Kingsgate Street, and St Cross. Its period properties — many built in soft red brick and local stone — typically feature six-over-six box sash windows with slim glazing bars. Replacements within the historic core must respect these traditional proportions and sightlines.

Winchester's conservation areas include the City Centre, St Cross, and Hyde. Properties around the Cathedral Close and other protected streets require like-for-like replacements with authentic horns and glazing bar profiles.

Why Winchester 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 Winchester

Winchester'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.
