Based on my research, Cass Plumbing appears to be a reliable and professional business. They offer a wide range of services, including plumbing repair, installation, and maintenance, and seem to have a strong team of experienced plumbers. Many customers have praised their responsiveness, punctuality, and quality of work. However, some have mentioned that their prices can be high, and a few have had issues with customer service. It's worth noting that the company seems to be proactive in addressing customer complaints and working to resolve any issues. On the negative side, one customer had a particularly bad experience with a plumber who allegedly overcharged and did subpar work. Another customer mentioned that the company's office staff seemed unhelpful and unprofessional. Overall, Cass Plumbing seems to be a solid choice for plumbing services, but customers should be aware of the potential issues and be prepared to negotiate prices or advocate for themselves if necessary.
