"You simply will not find a more conscientious diving firm in the Seattle region. Double J Diving has been diving regularly on our 40' Tiara in Elliott Bay Marina since early 2010 and has provided us with fantastic service. Janel always emails us the week before we are on the schedule and then calls me after every dive to inform me of Jorge's findings. When they felt that the time between diving intervals could be extended, she promptly informed us. When a nice deck brush found its way to the bottom of our slip, Jorge gladly retrieved it, rinsed it with fresh water, and left it secure on the back deck. The customer service received from Double J Diving is unmatched. I would recommend them to anyone with underwater maintenance needs."
