Growth came from repeat customers in older Buffalo homes and newer suburban builds that need reliable plumbing and flooring work.
The company builds on practical experience fixing issues common to Western New York: freeze-related pipe problems, basement water intrusion after lake-effect storms, and aging plumbing in century-old houses.
