I used Betz Pools for the hot tub repairs and maintenance for a couple of years for things like fixing the leaks and miscellaneous parts replacement. The work done is solid and the pricing was reasonable. The thing that was very though with them though is scheduling the work and getting the technician on site - they seem to be very busy with some probably bigger (pools?) projects and rarely can provide the date when they can send someone to do the work needed. At one point I also wanted to look into the spa parts refresh (pump, control panel), but it was impossible to get the estimate from them, to the point that I had to give up on this.
