Professional Narrowboat Hull Blacking
Protect your narrowboat with a professionally prepared and expertly applied hull blacking service from Blisworth Tunnel Narrowboats Ltd. A well-maintained hull is one of the most important investments you can make in your boat. Regular blacking helps protect the steelwork from corrosion, extends the life of your hull, and maintains your boat's value. We recommend that most narrowboats are re-blacked every 2–3 years, depending on usage and the coating applied.
Thorough Preparation Makes the Difference
The quality of any hull blacking job depends on the preparation. Every boat is first lifted from the water and cleaned using our high-powered hot pressure washing system, removing mud, algae, loose coatings and other contaminants. Using hot water provides a far more effective clean than a standard cold wash, giving the new protective coating the best possible surface to bond to. Our heated dock allows us to work in the right conditions throughout much of the year. By controlling the temperature when required, we can help ensure the hull is dry before coating and provide a more consistent environment for application, particularly during colder months. This helps achieve a high-quality finish and reduces unnecessary weather-related delays.
If your hull requires additional attention, we also have an on-site professional welder with over 30 years of experiencewho can carry out pit welding and other welding maintenance as needed. We can also replace anodes when required, helping to keep your boat properly protected between blacking intervals.
