Very professional, we were thrilled with them. Our pool was over 22 years old, plaster rusting through and tiles falling off. Badly needed to be redone. I took a few bids from other companies. Shasta's was about $2000 higher than others, but they just seemed far more knowledgeable. The others all seemed to rely on subcontractors, who each had their own schedules and warranties, whereas with Shasta it was all through them. Start to finish they did a great job at helping us choose what we wanted, showing us the pros & cons of different surfaces, and keeping us informed every step of the way as to what would be happening next, and when. Couldn't be happier.
