One workshop for the entire boat

The advantage of a comprehensive service is that the same team inspects the entire boat. If a water leak, an electrical fault, or worn upholstery is discovered during an engine inspection, it’s resolved during the same visit and with a single quote. For boat owners who are short on time, that means fewer phone calls and a boat that’s ready sooner.

Engineering and Refit

For larger-scale projects, Valnau offers naval engineering services: refit studies, structural repairs, and inspections using non-destructive testing. A well-defined project from the outset prevents surprises regarding budget and deadlines, especially when multiple trades are involved.

Tips for Requesting a Quote

• Specify the make, model, and hours of the engine or equipment.
• Send photos of the malfunction or the area to be repaired.
• Indicate where the boat is located: at a dock, in a dry dock, or on a trailer.
• Ask about timelines and the availability of replacement parts.
