In 1858, one enterprising individual invested his life savings of $200 to start a business grinding key stops for plumbers in Philadelphia. More than 150 continuous years of service later, that business is known as Hajoca Corporation. Hajoca has a robust history of helping to shape advances in plumbing. But we attribute our success to two simple truths - a unique business philosophy and talented people.
<h3>If we seem big, please take a closer look. Our roots run very deep.</h3>
Hajoca blends the clout of a large company with the opportunity of a small one. We understand that tastes and styles are different from place to place, so a "one size fits all" approach does not work. Our businesses have the freedom to operate like any local company and our managers conduct themselves with the focus and passion of business owners, right down to the products they carry and the people they hire.
Entrepreneurs welcome...and sought.
Good customer service means quality of work; exceptional customer service means quality of people. Members of our team are enthusiastic, driven to excel and singly steadfast in their commitment to service, integrity and reliability. They're also your neighbors and friends. They understand your unique needs because they've lived in your community for years.
Our locations are called Profit Centers and not branches, reflecting this independence. Our teammates have the opportunity to take home a share of the profits made in their Profit Center. Our decentralized culture gives each Profit Center Manager the same high degree of responsibility, autonomy, and accountability as an owner. The National Support Centers in Lafayette Hill, PA, and Baton Rouge, LA, are dedicated to enabling the success of our Profit Centers. Teammates at these locations and throughout the US provide services that are essential for our Profit Center Managers to have a playing field on which they can succeed through their own efforts and ideas. The company will continue to grow and prosper because our fundamental business philosophy works: emphasis on entrepreneurial spirit, expert knowledge, strong incentives for our teammates, and devotion to Hajoca’s proven business principles.
