Raen, it can be advantageous to deal with the company who pre-treated your home and foundation prior to construction. For example: Our resale Patio Villa was treated initially by Dean's and the original homeowners continued to use them after their closing. When we purchased from the original homeowners, they said if we continue with Dean's, the lifetime warranty for termites would transfer. I checked with Dean's and indeed found that to be the case. To us, it seemed like the thing to do! I checked on feedback related to Dean's as well as some info/pricing for other companies' services and felt sticking with Dean's was the best choice.
