Hi Catherine, it sounds like you got the big sales pitch for a preventive treatment. Soft window sills could be sign of water damage and a leaking window. It doesn't even sound like termites to me.
Sentricon is designed to be a profit maker for the companies that install it and service it. Sentricon is also sold under the name "Hex Pro" for "non-licensed companies". If you have active termites, Sentricon by itself is not the best treatment plan. For a preventive treatment, Sentricon is good, but also the most expensive overall.
I would recommend to get a second opinion. Bull's Pest Control is located in Denton and has been in business for many years. Call Barry "Bull" Combs and discuss this. He is a friend of mine, all around good guy and he gives Free estimates. Bulls cell # is 940-390-5704. If you call Bull, tell him Ron referred you.
To answer your question, the reason they inspect every 6 months is to keep you renewing the service every year. Studies indicate that the renewal rate for once a year inspections are much lower than for bi-annual (every 6 months) inspections. Basically, they want to keep renewing you at $300 per year for as long as possible.
By comparison, Termidor (a different treatment) will last up to 15 years.
Sentricon Always Active will last up to 7 years once installed. So in essence there really is no need to inspect it at all. The company pays Dow $50 per year for the agreement and pockets the rest.
Let me know if you have any other questions.
