The Van der Kley organ of the 'Vaste Burcht' church in Schiedam had water damage from a leaky roof. In particular, the Great soundboard was very wet. J. L. van den Heuvel Organ building was commissioned to repair the organ.

All the pipes of the Great were removed to gain access to the cones of the windchest. The windchest was cleaned and damaged cones were renewed. Also, all membranes of both manual chests were renewed. The pipework was inspected, cleaned and if necessary repaired before they returned on the windchest. The voicing was checked and corrected where necessary. The work was concluded with a general tuning of the organ.

Voicing of the new pipework (Van den Heuvel) and the historical Schmidt (1813) en Blank (1966) pipes is carried out as well as repairs.
The church has a gallery with pictures of the organ.

Inauguration took place on March 23rd 2012 by the local organists.

The J.C. Schmidt/K.B. Blank organ (1813/1966) of the Gereformeerde Kerk in Boven-Hardinxveld was modified and enlarged during Spring 2012. The organ case is hereby expanded to include two additional fields to accommodate the enlarged pedal. The Positive received new pipe work in a better scaling as the existing pipe work made by Blank did not blend well with the original Smitdt pipe work.
