Is there a local dynarod company around?

[pilsbury]

My tenants are having ongoing issues with a blocked sink in their kitchen, we've tried soda crystals and Bullitt which normally shifts everything, but it hasn't worked, so it's time to call in higher experts... Just wondered if anyone recommended anyone local otherwise I'll try dynarod in the morning.... Thanks!
