We have a contract with them for our tankless water heater and for our heating and ac unit. They came today to service both. They were both very polite and professional. The plumbing tech Joe is without a doubt the greatest technician we have ever had. He is friendly and so pleasant. He is so thorough on the plumbing. We absolutely recommend Chesapeake. We will ask for Joe for any and all plumbing calls. Excellent service.
