William Richards a family-owned specialist in the design, manufacture and installation of high-performance Timber Sash Windows. With over 40 years of experience, our reputation is built on traditional craftsmanship, precision joinery, and a deep respect for architectural heritage.

Founded by William Partridge - a master woodworker whose roots lie in instrument making, our approach combines time-honoured techniques with modern performance standards. Every sash window we produce is tailored to enhance or replicate the character of period properties that are nestled in conservation areas, delivering exceptional thermal and acoustic efficiency without compromising historical detail.

Our expert team works closely with architects, conservation officers, and property owners to deliver sash windows (amongst other joinery) that are both aesthetically authentic and technically refined. As proud sponsors of the Architects’ Journal Heritage Award, we are committed to supporting excellence in heritage design and the continued preservation of the UK’s architectural legacy.
