Castle Improvements is focused on providing high quality products, service, and customer satisfaction - we will do everything we can to meet expectations. We design, manufacture, supply, and install a vast range of handmade standard or bespoke products to your specifications, requirements, timeframes, and budgetary constraints for many walks of life including the building trade and general public.




Staircases made to measure - hand selected timbers from joinery grade softwood to character grade American black Walnut.


We can design & fabricate all staircase requirements whether it is the whole staircase or one of the components. Most refurbishment and loft conversion projects require new staircases to match style or existing design.


We have all necessary machinery to make custom or matching hand rails, spindles and balustrades



Windows and Doors


All types of windows can be supplied and installed from standard period box sash, flush casement windows or custom designed in softwood, hardwood, or uPVC.


Our replacement window service ensures that the new windows match old/existing windows exactly to meet Conservation area requirements.


All our windows are weather proof, draught proof, sound-proof, and double glazed to meet current Building Regulations.


Doors can be manufactured to any specification, shape and size.
