The preservation of historical objects and their proper handling is one of our team's highest priorities. Paintings, historical frames, sculptures, and similar items are conserved in our specialized workshop according to academic standards.
In the field of stucco and architectural surfaces, the FRANCK team has successfully completed numerous conservation projects in collaboration with the Kunst-Stuck Atelier Chaudot based in Speyer, among other projects. These projects include a variety of works in the local Rhine-Neckar district around Mannheim/Ludwigshafen and villas along the German Wine Route. Through the combination of expertise and experience, our team possesses the necessary sensitivity for preserving local identity-defining architecture.

Environmental factors such as light and changing climate, as well as improper framing, can lead to various damage phenomena in paintings. These include issues such as paint layer losses, damage to the canvas (e.g., tears, deformations), or a distorted colour impression due to a yellowed varnish or significant surface dirt.
Our team of academically trained conservators develops an action plan tailored to each object, thus ensuring the proper conservation of both historical and modern artworks.
In the field of painting conservation, we offer the following services:
-
Examination and conservation of panel and canvas paintings
-
Conservation of the paint layer and the support (canvas or wood panel) (e.g., consolidation of loose paint layers, surface cleaning, closing canvas tears)
-
Reconstructive measures (e.g., filling in missing areas, retouching, varnish removal)
-
Documentation of the condition and conservative measures
-
Conservative framing of paintings to protect against punctures, dust deposits, and climatic influences
In our framing and gilding workshop, we also offer consultations on various framing options and decorative frames. Our frame selection includes both simple industrial mouldings and gilded handcrafted frames.
Our team of academically trained conservators also specializes in the conservation of sculptures and historical furnishings within church interiors (e.g., pulpits, and altars). We have established our conservation skills in both heritage conservation projects and projects for private clients.
Our scope of work includes professional planning, preliminary examination, development of a tailored action plan for each object, and its practical implementation.
Our services include:
-
Painted / visibly wooden sculptures and furnishings
-
Examination of the technological structure of the object (e.g., stratigraphic analysis of various paint layers, examination of material composition such as pigments and binders, etc.)
-
Documentation of the condition and conservative measures
-
Conservation measures for the paint layer and wood support (e.g., consolidation, cleaning, wood additions)
-
Reconstructive measures (e.g., filling in missing areas, retouching, removal of coatings or disruptive overpainting)


Improper storage, mechanical stress, transport, and other factors can quickly lead to damage of decorative or mirror frames with delicate ornamentation.
The focus of our frame conservation is on restoring the integrity of the frame and preventing future damage to both the frame and the framed object.
Our services in frame conservation include:
-
Development of a customized conservation plan
-
Documentation of the condition and conservative measures
-
Conservation measures (e.g., consolidation, cleaning)
-
Reconstructive measures (e.g., filling in missing areas, reconstruction of ornamentation, retouching, re-gilding, removal of coatings or disruptive overpainting)
In the field of examining and preserving historical architectural and stucco surfaces, our team has extensive professional experience and expertise. Our clients include heritage authorities, churches, and private individuals.
We offer a variety of services:
-
Examination: Using stratigraphic analysis, microscopic examinations, and, if necessary, sampling and cross-section analysis, we can examine and document the structure and material composition of the individual paint layers.
-
Conservation measures (e.g., consolidation, cleaning)
-
Reconstructive measures (e.g., filling in missing areas, retouching, stucco additions)
-
Reconstruction of historical wall finishes and stucco elements


The basis for developing a suitable restoration or conservation concept is the conservation assessment. This includes, among other things, the stratigraphic examination of the individual paint and support layers to gain information about the original appearance and technological structure (materials, techniques) of the object.
Through meaningful investigation windows, the layer sequence, and thus the object's history, can be represented (see photos).
This type of assessment is particularly used in the preservation of historical monuments, such as on historical architectural surfaces (facades, stucco, wall paintings), panelling, and sacred interior fittings like altars or sculptures.
Our team of academically trained conservators carefully creates documentation of the findings and the condition of the object (damage, previous restorations) according to the guidelines of the State Offices for Monument Preservation.
In addition to on-site assessments, additional services can be provided:
-
Sampling and creation of cross-sections to visualize the layer sequence (see photo)
-
Scientific analysis of pigments, fillers, or binders by renowned specialist laboratories
-
Evaluation and contextualization of analysis results
-
Sample axes or templates to illustrate the assessment results

Sacred and secular furnishings, such as painted wooden objects (e.g., altars, pulpits, galleries, wood panelling), often exhibit various forms of damage. Causes can include a fluctuating indoor climate or exposure to harsh environments. Our large team, consisting of academically trained conservators and skilled craftsmen (e.g., gilders and church painters), can professionally handle the conservation and restoration of these furnishing objects.
Our services include:
-
Conservation measures (e.g., cleaning, consolidation of loose paint)
-
Restoration measures (e.g., filling in missing areas, retouching, re-gilding)
