A great experience all around ...
Excellent Service (from Katie in the office to the field team which includes the owner, Larry), the entire Team is knowledgeable and friendly in their respective roles,
Very Responsive (especially if you have a major-priority issue);
High Quality / Reliable Work (never a follow-up on the same repair), and
Fair, Honest & Upfront prices (the lowest service call and hourly pricing I've seen in Vegas area and without the huge mark-up on the parts that the others charge).
I had used several different providers my first three years in Vegas but have been a loyal customer for the last 7-8 years (fun fact ... this is family owned and run business that has been around long before the Vegas' boom). If you have a home repair warranty company, I discovered that mine had already vetted / approved Calavan's and would allow me to request them whenever a covered item needed repair or replacement.
I have peace of mind knowing that when the pool/spa does need work, I can count on this Team to take care of me and leaving me feeling good about what is otherwise not a fun time.
