Timber sash windows supplied and installed across the UK
Timber sash windows engineered for style and stability
Our sash windows are crafted from stable hardwood timber, selected for moisture control, structural strength and long-term performance. We manufacture box sash windows and weighted sash windows, shaped with mechanical precision and hand-finished for accuracy. Units can be built with double glazed sash windows or fitted with secondary glazing sash windows where thermal upgrades are needed. Our workshop prepares each sash system for either installation or full window sash replacement, including restoring or removing existing box frames. Finishing options meet external-grade standards for the British climate.
Chris Carpentry produces and fits wooden sash windows tailored to existing openings, design heritage and regulatory specifications. Each window wood sash is matched to the architectural context and assembled with performance goals in mind—such as energy retention, smooth motion and sound insulation. Every frame is fitted with integrated draught-proofing and the right weight system—either traditional cords or concealed spiral balances. All measurements are taken on site to ensure consistency across elevations.
For renovation projects, we deliver precise window sash replacement services. This includes detailed property checks, accurate removal of previous sashes and exact installation of new components. Depending on requirements, we can replicate original mouldings or introduce updated profiles that meet performance targets. Each timber sash window is tested for function and sealed against water ingress. All coatings, hardware and seals are rated for exterior use and applied to maximise lifespan.
We install sash windows in both individual homes and full-scale residential refurbishments across the UK. Whether you’re replacing outdated sashes or starting from scratch, we ensure that all box sash windows and weighted sash windows are aligned with your site conditions and preferences. With 15+ years’ experience, Chris Carpentry delivers consistent results with exact fitting, solid construction and full service support.
