Hot Water Pros did exceptional work for me; they will be my go-to for all future plumbing needs. Cameron and his crew are incredibly thoughtful, responsive, and professional. Their workmanship is first-rate, and their pricing is very competitive. When my 10-year-old water heater started to leak, they took the time to understand my needs and didn’t try to sell me on installing more than what my family and I need or will use. That kind of service is special.
