Best Noninvasive Leak Detection in Gilbert AZ

Absolutely terrible. $450 to detect a pool leak. Spent 20 minutes at my house and marked a spot. I waited 6 weeks for them to send the report so I could give it to the repair company. No leak within 4 foot radius. Company said 5 foot radius needed and no warranty since it had been more than 30 days. They waited to send me the report till after the warranty expired just in case it was wrong. Negative 5 stars would still be too nice.
