Despite the plethora of perfect 10 ratings already for Kevin, I feel the need to add another. I emailed regarding a Carpenter Ant problem which had just appeared and had a response almost immediately by email, with a follow-up call minutes later.
Over the phone Kevin was polite, up-front with pricing and likely course of action, took the time to listen to me without just making assumptions, and was not offended when I said I was calling some other folks too (all highly-rated here on Homestars).
While the other guys quoted similar or even identical prices, Kevin's full 1 year warranty and enthusiasm made me decide to go with his services.
In person, Kevin was enthusiastic, obviously loves his job, and basically did everything he said he would on the phone. He quickly sought out the most likely spots for the main infestation, used a combination of in-wall and surface treatment, explained to me everything he was doing and both arrived and departed almost precisely when he estimated he would.
He also reminded me multiple times that a follow-up visit might be required, and not to hesitate to contact him if there were still any ants present after a couple of weeks.
In short, I could not have expected more from his services and he is a genuinely pleasant person to deal with as well. I will probably add an update in a month or two to confirm whether or not follow-ups were required and how those went if appropriate, but for now I have no hesitation in giving another perfect rating to Kevin.
