Sash Windows in Richmond

Richmond's Timber Window Specialists

Richmond upon Thames is one of London's most prestigious boroughs, famous for its stunning Georgian architecture, riverside properties, and the magnificent Richmond Park. The elegant townhouses along Richmond Green, the grand villas of Richmond Hill, and the period properties throughout the area represent some of London's finest architecture. At Prime Sash Windows, we manufacture bespoke timber sash windows that honour Richmond's heritage while delivering modern thermal and acoustic performance.

Richmond contains numerous Conservation Areas and many Listed Buildings, with particularly strict controls around Richmond Green, Richmond Hill, and the riverside areas. Our craftsmen have extensive experience working within these protected zones, creating windows that satisfy both Richmond Council heritage officers and the high expectations of Richmond homeowners.

Why Richmond 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.
