About Harkin Construction


A Craftsman’s Story Rooted in Experience

Harkin Construction is built on decades of hands-on experience, a passion for carpentry, and a commitment to doing things the right way.


Sean Harkin grew up in Ireland, where he began working in construction at just 15 years old, gaining experience across a variety of trades. While he always had an interest in carpentry, it wasn’t until he moved to the United States in 1998 that he had the opportunity to fully pursue it. By 1999, he was working as a carpenter, developing the skills and precision that now define his work.


After years of working with other companies, Sean started Harkin Construction in 2010—bringing his experience, craftsmanship, and work ethic directly to homeowners throughout Lancaster, PA.

Attention to Detail You Can See

Sean’s background in carpentry shows in every project he completes. Whether it’s custom trim work, built-ins, or a full renovation, he focuses on the details that make a space feel complete.


He takes the time to understand each client’s goals and works closely with homeowners to bring those ideas to life—whether it’s a small project that takes a few days or a larger renovation spanning several months.

A Personal Approach to Every Project

One of the things that sets Harkin Construction apart is the level of personal attention each project receives. When you work with Sean, you’re not dealing with a large crew or a rotating team—you’re working directly with the person who will be managing your project and completing the work. From the first conversation to the final details, Sean is involved every step of the way. This approach allows for better communication, greater consistency, and a finished result that truly reflects your vision.

"Sean was referred by our realtor to install new wood flooring for our 2nd floor outside sleeping porch. Sean was wonderful to work with. He explained his recommendations and outlined each step of the project. His pricing was competitive. The mahogany wood chosen was beautiful. We were so impressed we decided to have Sean paint the railings and moldings, as well. I would highly recommend Sean without hesitation!"
