Floodark barriers, maintenance now that company no longer in business

Hafren

We had Floodark barriers fitted to our house in 2008, following flooding and, as recommended, we have had the seals replaced every three years since then and have been very happy with them. However, we are due to have the seals replaced this year and the company is no longer in business. Does anyone else have the same problem and have they found anyone who can help with maintenance? Or should I start to look for replacements before the seals fail?

Based on the product information the seals should have a 20 year lifespan.
