This is the best spa repair person I’ve ever worked with. I had a leak with my Dimensino One Hot Tub. I had called a couple of other companies to come out and fix the problem. the other companies quoted huge charges for just showing up to evaluate the problem. Then I found A1 Spa through a friend’s recommendation. They quoted me a reasonable rate and they showed up when expected. Chester(the technician) was amazing in that he just tackled the problem even though it involved opening up the side of the hot tub and removing the insulation to get at the leak. I have nothing but great things to say about Chester Lewis.
