I recently had Kyle from J & J Service Tech Ltd bring my twenty-year-old hot tub back from the dead. I was seriously considering having the hot tub removed and disposed of, but Kyle completely rejuvenated it. He replaced all of the electrical components, fixed multiple leaks, replaced plumbing and thoroughly cleaned everything. Following startup of the hot tub, Kyle gave me a spa school to make sure I fully understood how to use the hot tub and chemically treat the water. Kyle is extremely knowledgeable, friendly and professional. I would highly recommend J & J Service Tech Ltd to anyone living in the Calgary area. I will definitely be using J & J for all my hot tub needs.
