The organ in Sionskerk of the Hersteld Hervormde Gemeente in Ridderkerk will be the third organ that we construct for Ridderkerk. In 1972 the organ of the Reformed Singelkerk (32/IIIP) was completed. In 1980 we placed a French-romantic organ (34/IIP) in the Bethelkerk of the Netherlands Reformed Congregation

The Sionskerk was opened in March 2015. The church building, built in brick in classical style, designed by architect Born, can accommodate around 700 people. The Van den Heuvel organ gets a place above the pulpit. The design of the organ case, just like the pulpit, is in late nineteenth-century, early twentieth-century style. The organ case and the gallery will be made of oak.

The instrument will have 29 speaking stops on Great, Swell and Pedal. We expect to be able to deliver the organ in 2021.

Latest photo update: 16 April.

Construction of the windchests has started, followed by the bellows and windtrunks.

Hervormde Kerk, Werkendam (2020) Hervormde Kerk, Werkendam (2020)

When the old village church of Werkendam was bombed at the end of the Second World War, the Witte organ from 1865 was also destroyed. The new church, built in 1952, was designed by the architects Nielsen and Spruit. One year after the construction of the new church, the Willem van Leeuwen firm in Leiderdorp was commissioned to build a new mechanical organ (opus 300) with a vertical slider system. Willem van Leeuwen was already oriented towards the historical organ in this time in the organ movement and it is special that he also builds a mechanical organ with a great, a positive and a pedal. Unfortunately the used the material was of poor quality. The organ case, for example, was made of spruce wood studs and frameworks with thin plywood panels.

vertikaleslepen 283x200

On the left you see the vertical slider system as used in Werkendam. At the bottom of the picture is the channel grid with a solid (!) wooden cover plate. The slider system is placed on top of that. This consists of a vertically placed beam with a pertinax slider on each side. Above the moving slider a fixed pertinax slider has been placed to compensate for the height difference. A cap clamped against the sliders, which consists of a pertinax bottom plate with a bakelite cap. When a key is pressed, the wind from the cancel flows into the vertical beam, through the movable slider, flows through the cap back into the beam to flow up into the pipe grids.


At the time of delivery, 8 of the 20 stops were reserved. In 1963 Van Leeuwen added two stops: a Fagot 16' was added to the Pedaal instead of the originally planned Octaaf 4' (which would already have been replaced by a Schalmei 4' in 1958), and a Roerfluit 4' was added to the Rugwerk, placed in place of the planned Quintadeen 8 '. On the Hoofdwerk a Cornet III took place instead of the planned Dulciaan 16 '. The following year, Pels & Van Leeuwen will fill the remaining vacancies.

In 1972 the organ was restored by Pels & Van Leeuwen, where wind chests and mechanisms were partially restored and the organ got a new oak case with a more elegant design. Three new stops were also placed. On the Pedaal the Spitsgedekt 16' was replaced by a oak Subbas 16' from Van Gelder, from the Willemskerk in The Hague, on the Hoofdwerk the Trumpet was replaced. Around 1980, the Cornet was replaced by a 5-ranked specimen from Groot-Ammers, which was put in storage. In 1974 the blind carvings were applied and the organ was  completed under the advice of the then organist Frans van Tilburg, who played the organ from 1957 to 1984.

Works 2020

In addition to cleaning the pipework and wind chests, all pipework has been checked. Many pipes were repaired with adhesive tape, even stopped pipes were made to tune with sometimes large amounts of adhesive tape. The Holpijp 8' and Roerfluit 8' are now fitted with felt seals. The labia of all pipes were cleaned and checked. The same applies to the cores, feet and corpi. Pipe feet of the pipes have been checked and if necessary repaired or provided with new feet. The tuning rols have all been checked and, if necessary, re-soldered so that a stable whole is created. After this, the voicing has been reworked.

The heads of the Bassoon 16' showed extensive oxidation and have been renewed. The voicing has also been improved, with resonator lengths being corrected.

Stop list

The desire to change the organ's stop list arose because the organ sounded very dated and thin. With some changes and adjustments, the sound becomes milder and more powerful and will therefore be more usable during the worship services. The Scherp of the rugwerk has been replaced by a Quintadeen 8' which was already forseen in 1953. The Dulciaan 8' was very unsatisfactory, both in terms of sound and voice stability. This stop has been renewed with a wider scale and is now completely of metal. The Mixtuur has been severely damaged by tuning works, partly due to its poor reachability. The composition has been reworked and pipework has been partly replaced and / or shifted by making use of the pipework of the Scherp. The Hoofdwerk Cornet has been renewed in a broader scale, so that the singing character is better expressed. The mounted position of this stop has also been adjusted so that the Hoofdwerk pipework is more accessible.



The corners of the bellow showed cracks, so they have been renewed. The rest of the leather is still in good condition, partly due to the use of linen in the hinges, so that the leather does not have to transfer mechanical forces. The leather sleeves have also been renewed, which are attached to the top of the bellow.

Hervormde Kerk, Nunspeet (2020) Hervormde Kerk, Nunspeet (2020)

In 1872 the firm of L. van Dam and Sons placed a new organ with two manuals and pulldown pedals in the Dorpskerk of Nunspeet. It had 17 speaking stops. It was originally placed at the west side of the church. At the begin of the 20th century the firm of Van Dam & Bergmeijer replaced the Clarinet with a Voix Céleste. After the enlargement of the church the firm of Leeflang relocated in 1960 the organ into the new part of the church.

In the years 1967/1968 the instrument was adapted to the spirit of that time and enlarged. Consultant was Wim van der Panne. A independant pedal division was added, pedalcouplers, a new windsupply system with movable windchests bottoms. The windchests grids recieved ply wood toppings on both sides. Sliders were renewed with a spring system. Also the Hoofdwerk windchest was re-organized wereby the Boudon 16 and Violon 16 were removed to make place for a Mixtuur IV-VI. The Voix Céleste was also removed and its spot was taken by a Cymbel and a narrow scaled Dulciaan both on its own slider. Key- and stopaction were modernized. The organ was inaugurated on January 25, 1968. It was played by Wim van der Panne and G. van Campen.

In December 2017, the contract was signed for a complete restoration of the organ. Organ consultant Herman G. Kamp will supervise the project. In addition to the necessary restoration work, necessary sound improvements are also being made. The original sound of the instrument will be partially restored by undoing the works that have seriously affected the sound. Later (valuable) additions will be maintained and, where necessary, improved. The work will be inspired by Van Dam's original concept, but without extensive reconstruction or copying of other Van Dam instruments.


The windchest folding bellows are detached from the windchests and converted into independent bellows which are put under pressure with weights. This will make the rigid wind supply more flexible and natural.



The removed Violon 16' and Bourdon 16' will return. Historical Van Dam pipework is available for this. The Mixtuur will get a new composition. The Trumpet was rebuild with new shallots and tongues in 1968. Historical Van Dam material is also available to undo this. The bass / treble seperation will also be available again.


The Dulciaan and Cymbel which do not fit in the organ sound are removed. Their place will be taken by a Quintfluit and a new Klarinet.


The current arrangement of the pedal is very tight and the sound development is insufficient. Behind the organ a separate case will be made containing a wooden Prestant 16, the Octave 8 and a new Bazuin 16' with full length wooden resonators. The current pedal wind chest will accommodate the remaining voices.

Pictures of the crafting of the new Prestant 16' pipes and the Bazuin 16' resonators:

The Hoofdwerk and Bovenwerk windchests are being restored, whereby the leather pulpets return. The Hoofdwerk windchest is enlarged with a side block for the Violon and Bourdon. The toeboards and pipe grids of the in 1968 placed stops will bee renewed or adapted in the Van Dam style.



Unfortunately, a good number of pipes were affected by corrosion, in particular the pipe feet. This was also noted in 1967/68 and part of the pipe feet had already been partially replaced. The pipework is then again re-racked.



The separate pedal case will be placed behind the organ. The case is partly set up and the first pipes have been placed. Between the existing organcase and the new pedal case a part of the new windsupply is located. The remaining part finds a place below the hoofdwerk windchest.

Hervormde Kerk, Yerseke (2019) Hervormde Kerk, Yerseke (2019)

The Flentrop company built a new organ in 1951 for the Reformed Church in Yerseke. The façade is a design by the architect J.W. Janzen. The instrument in the Reformed Church of Yerseke is a very solidly built organ. It was designed and built at a time when a major change in organ building took place (a refocusing on the mechanical "baroque" organ type). It is one of the earlier organs in which Dirk A. Flentrop presented his knowledge for this type of organ that he built according to the mechanical slider chest system. This organ has a beautiful sound and the pipe scaling is generous, it is definitely not a neo-baroque sound.


Despite the very characteristic elements and qualities, there are also weaker points. The quality of the reed stops is unfortunately below the level that is nowadays considered desirable. The sound development is certainly characteristic of the construction period, but this is nowadays done differently (more 'user-friendly' and more fitted to contemporary use in the worship service).

In 1975/76 the organ was transferred by the builder to the new west wall of the church. A pneumatic pressure Tremulant was built in by Flentrop and the reed stops were re-worked. The Nijsse company carried out major maintenance work in 2007. Whereupon the Spitsgedekt 16 of the pedal was replaced by an oak Bourdon 16. Again, the reed stops were re-worked. Unfortunately without the desirable result because the reed stops were still unstable.

Works started on the Flentrop organ in July. The Regaal 8' has been replaced by a completely new Dulciaan 8' with the bottom octave with half length resonators,being made in connection with the available height of the rugwerk case. The Hoofdwerk Trumpet 8' has also been renewed whereby the resonators have been reused. The Pedal Fagot 16' got new shallots, tongues and tuning wires. To increase the sound-color possibilities of the rugwerk, the Scherp has been replaced by a Sesquialter using pipe work from the Scherp supplemented with Flentrop pipe work from the organ builder's stock.


The tremulant bellows have been renewed and the sound effect has been improved. Furthermore, restoration of the console has been carried out in which worn keystrokes have been replaced, broken register shields have been renewed and worn felt linings have been replaced. The back wall of the Rugwerk was finished with thin plywood and very fragile. The finish has been updated and is now 10 mm thick. The hatch layout has also been adjusted so that the reed stop is easily accessible for tuning. Subsequently, the mechanics were checked and adjusted and the voicing was corrected.

Hersteld Hervormde Kerk, Lunteren (2019, 46/IIIP) Hersteld Hervormde Kerk, Lunteren (2019, 46/IIIP)

The Hersteld Hervormde Gemeente is currently building a traditional church seating 1.200 people. The design is by architect Marco Born. Already in 2008 Van den Heuvel Orgelbouw was involed in the plans of the church to get to an optimal acoustic church building.


The organ will have 3 manuals and pedal and includes a 14 stop swell division. The sound will be wealthy, solistic and singing: a real 'Dutch' organ optimal for community singing but also fit for as a solo instrument. The classical organ case designed by Van den Heuvel Orgelbouw will be crafted of first class European oak.

Maranathakerk, Dinteloord (2018) Maranathakerk, Dinteloord (2018)

After the construction of a new church for the Reformed Congregation in Dinteloord in 1982, the existing positive of Leeflang from 1976 proved to be too small for the church. The Leeflang company was subsequently commissioned to build a larger organ. Consultant was again Arie J. Keijzer. The architect of church, J. Valk from Soest, designed the façade. The organ was inaugurated on 4 May 1984 with the consultant at the organ.

in 2018 J.L. van den Heuvel Orgelbouw was commissioned for the repair works. Hereby the organ was cleaned, the windsupply was re-leathered, the voicing was corrected and the mechanical action was reworked and re-adjusted. The Sesquialter consisted of a conical Nasard and a Tierce in flute scaling. This stop was split into a separate Nasard 2 2/3 and a Terts 1 3/5 each with its own slider and stop knob.

Stedelijk Museum, Schiedam (2017) Stedelijk Museum, Schiedam (2017)

The central hall of the Stedelijk Museum of Schiedam was formerly used by the Waalse Gemeente. The building was also known as Gasthuiskerk because it was part of the Sint Jacobsgasthuis.

In 1773 organ builder Hess constructed an organ for the church. It was inaugurated on 9 September 1773. The organ was played by Joachim Hess, organist of Gouda, and Mister Hagen jr.

Recently we restored the organ which was in unplayable condition. Consultant during the works was Arjen Leistra, city organist of Schiedam and also organist of the Grote Kerk of Schiedam. The restoration works included the two large wedge bellows, cracked wind trunks, optimization of the wind supply, metal and wooden pipes as well as the action. The voicing was only corrected where needed. Also a humidifier was installed.

In 2016 the “Hersteld Hervormde Kerk” is building a new 900 seat church. The traditional design of this church is made by the well known Dutch architect Marco Born.

ouderkerk exterieur 500x302

The church committee decided to install a fine pipe organ. Since many churches are closing in the Netherlands the best quality organs are quite often sold to Van den Heuvel-Orgelbouw. Van den Heuvel (trained by Dirk A. Flentrop) bought the last few years, among other organs, 5 important Flentrop organs, and just purchased a well known Flentrop-organ from the Maranatha-church in Amsterdam. The measures of this organ were suitable for the church in Ouderkerk. The customer however requested Van den Heuvel to make important improvements, alterations and to include additional (wider scaled) stops, as well as a completely new traditional organ case design with wood carvings. The organ has to be delivered in 2017.

The Flentrop organ had a traditional winding system with 4 folding bellows. The windsupply is redesigned and includes an additional wind motor and one additional bellow. The Flentrop bellows are re-leathered, also the wind trunk system will be renewed.

Hervormde Kerk, Scherpenisse (2016) Hervormde Kerk, Scherpenisse (2016)


Already in 1203 the a church was mentioned in the archives. Todays church dates from the fifteenth century.

The first details of a church or chapel of Scherpenisse date back to 1203. This church was dedicated to the Virgin Mary and belonged to the deanery South Beveland and chapter of Old Minster in Utrecht. In the church were three chapels; dedicated to Saint Barbara, the Holy Cross and St. John.

Scherpenisse Hervormde Kerk

The current Reformed Church of Scherpenisse dates from the 15th century. Around 1462 a new choir was built. The aisles of the church arose probably around 1500. The aim was to build a high church tower. However, it has never been higher as it is now. The construction was halted, possibly related to a lack of funds and the floods in the 16th century as the St. Felix's Flood and the Saints flood.
The transept and the cancel of the church were so dilapidated in the 17th century that the collapse of the chancel into the church threatened the church in 1685. The situation remained poor until the mid-18th century. After stone and lime fell from the walls, the pulpit and the seats were transferred into the nave. Two years later fell debris on the pulpit, Pastor Matthias Janssen wanted to do no more in this dilapidated building. Money for the restoration of the church was missing so the choir and transept were demolished in 1753. A wall at the former separation of nave and choir now closed the church. It was a window until in the 70s of the 20th century when it was bricked. In the church there are many 17th-century objects such as the pulpit and a chandelier. The oldest gravestone dates back to 1441. The oldest of the three church bells was cast in 1484 by bell founder Sijmoen Waghevens Mechelen.
In 1971-1974 the church was restored, followed by the most recent church restoration in 2009.

First organ

Already in 1563 there was an organ, because in that year the organist is mentioned in the archives of the Church of Scherpenisse. After 1600, probably at the beginning of the 17th century, the organ was removed since it is obsolete after the Reformation. Also, in the near Tholen City the organ disappeared in that time from the church.

Current organ

In 1907 Mart Vermeulen from Woerden built a two-manual mechanical organ for the Reformed Church of Scherpenisse. The instrument had a pulldown pedal and was placed above the entrance. It is a mechanical organ with 1,044 pipes. For this, a value of f. 2500, - paid. The instrument was designed partly new and complemented by existing 18th and 19th century material of various origins. The organ was inaugurated on April 28, 1907. The top façade fields are dummy pipes, the other are speaking pipes consist of the largest pipes of the Prestant 8' and Octaaf 4'. The organ has two white angels with trumpets and center David with the harp.

The organ was renovated in 1952 and two stops of the second manual were modified: Open Fluit 4' and Vox Celesta 8' were replaced by Prestant 4' and a Nasard 2 2/3'. The first was made of new pipes, the second from the Vox Celesta. This was done by Fa. Koppejan. The bellows were connected to an electric wind machine. The foot control on the back of the organcase however were left intact. At the church restoration in 1971/74 the windchests were restored and plywood cover plates (top and bottom) were provided. For the slider sealing telescope tubes were used. Also, the trumpet was split into bass and treble. The restoration was carried out by K. B. Blank & Zn. Herwijnen in 1973. Around 1984, the mechanical tremulant is replaced with a pneumatic one.

Restoration 2016

The restoration was carried out as a preservative one. The stoplist changes of Koppejan and the pywood cover plates and the division of the Trumpet by Blank were maintained. Both the organ case and all internal parts were cleaned and where necessary treated against woodworm. The double rise bellow (224x110cm) has overall been restored including the renewal of the hinge points.

11 pictures:


The wind machine was placed in a primitive box consisting of chipboard and polystyrene. A new fan case was manufactured, placed on springs in order to minimize the transmission of motor resonance. The wind channel between the motor and bellow has been reworked. Wind channels were cleaned and checked, and if necessary completed in style.

The wind chests were transferred to the workshops in Dordrecht and there followed the first cleaning and inspection. The loose glue joints and cracks are repaired. During the latest restoration by Blank the wind chest grids were provided with sheets of plywood (10 mm, finished with oak edge). The ventil leather turned out to be in excellent condition and is therefore merely cleaned. However, the leather of the glands was worn, they are also renewed. Blank has telescopes applied as slider seals. The construction has been adjusted and the seals have been replaced by ‘Liegelind’ rings.

7 pictures:


The keydesk has been cleaned. The excess lateral play has been eliminated. All parts were checked and processed. The pins were redirected, new pressure felt pads were applied. The pedal keyboard was restored and the worn keys were replaced. The action was cleaned (mold!) and restored. The beechwood parts of the action had much active woodworm present. These have been treated or replaced. Wire work and leather nuts of the key action where renewed where necessary The stop action mechanism is cleaned and repaired, remove existing excessive backlash, torque and pivot points checked and repaired, rust from the metal swords and iron work is re-blackened. The keyboard cheeks and knobs again blackened.

8 pictures:


The pipes have been cleaned and restored: completely checked and where necessary repaired, all in style of the existing pipework and earlier repairs. The corroded or damaged pipe feet were replaced. The wooden pipes were cleaned of flaking paint, and updated. The pipe construction was checked and leaks were repaired. The leather of the stoppers was replaced if necessary and closings checked and optimized. The trumpet was completely taken apart and cleaned. Leather renewed if necessary. All parts checked and repaired, tuning wires adjusted and oxidation removed. Voicing was optimized within the existing concept of this stop.

41 photos:


After all the parts were restored, all parts repackaged and transferred to the church, the assembly could start. After completion the voicing of all pipes was leveled within the character of the concept.
