Sash Windows in Potters Bar

Potters Bar's Timber Window Specialists

Potters Bar offers an attractive mix of Edwardian, inter-war, and Victorian properties, set within easy reach of London whilst enjoying the benefits of the Hertfordshire countryside. The town's period homes, particularly around the older areas near the station, require windows that complement their traditional character. At Prime Sash Windows, we manufacture bespoke timber sash windows that honour Potters Bar's heritage while delivering modern thermal and acoustic performance.

Potters Bar falls under Hertsmere Borough Council, which takes heritage matters seriously. Properties in the older parts of town and near the Green Belt boundary often require careful consideration of planning requirements. Our team understands these local considerations and creates windows that meet both heritage expectations and building regulations.

Why Potters Bar 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.
