The best care for your sash & case windows

Your local specialists in sash and case repair and renovation.

Bringing your sash and case windows up to date

Sash and case windows add traditional elegance to any building but as with many period windows, they are prone to draughts and leaks.

Second to none for original design quality, weather proofing and finish, our windows provide the high performance you expect from a modern unit while staying true to the traditional look of your original sash and case window. We will match exactly the original windows in your property, be it home or office, to the complete satisfaction of the Edinburgh Planning Department and Conservation Committee. The only difference between the original window and the replacement we provide at JBC is that the new window is an exact replica but in perfectly new condition. JBC are also experienced in the design, manufacture, installation and repair of window shutters.

And all to the complete satisfaction of the Edinburgh planning department and conservation committee.

Stay warm with our double glazed sash and case windows

If allowed, we can double glaze and draught proof your sash and case windows. We use Heritage double-glazed units when strict conservation rules apply, which can be glazed straight into the original single glazing checks. For strict conservation situations where double glazing or window replacement is prohibited, our secondary glazing service is a great alternative.
