I had my house in Hermosa tented for termites in Dec. 2009 by Class Exterminators ("Kill 'em with Class") in Torrance. They also repaired all termite damaged wood. They gave a 2-year warranty. In August 2011, I sold this house. When I contacted Class for a Clearance Report, they did another thorough inspection, found 3 tiny areas of damage, fixed that, and issued a Clearance Report. There was a small cost (under $200) for the second inspection and repair work.
That's my experience--hope this helps.
