Solid foundations. Groundbreaking solutions.
It’s what we’re made of.

What We Do

We help contractors build better, safer, more sustainable buildings. We also help them get more jobs by offering the best selection of building-envelope solutions, backed by the most responsive customer service in the industry. The clients we work with know they can rely on us to deliver the products they need — on time, every time. That’s because we believe contractors should expect more from their distributors — more inventory, more product knowledge and more personalized service.

Our Culture

No matter how big we get, it’s the small things that make our culture contagious. The way we greet our clients by name and celebrate each other’s milestones. How we go out of our way to help clients solve real, everyday problems. The way we take pride in sharing our latest project with family and friends. Over 40 years, we’ve built more than a business. We’ve built a family.

Our History

Like many family-owned businesses, Kenseal started small with the vision of two entrepreneurs. Our founders Ken Lippmann and Pete McKinnell laid the foundation for Kenseal in New York in 1977. As demand for our products and services grew, they expanded to Connecticut, Baltimore and beyond. Since then, we’ve established roots throughout the East Coast and built a solid reputation based on experience, integrity and innovation. We’ve stayed true to our family-owned roots and are now in our second generation of ownership. It’s been our privilege to watch the communities we serve grow over the past four decades.

Following in our founders’ footsteps, we continued to explore new ways to grow and innovate. In that spirit, we were thrilled to partner with A.H. Harris. It’s a strategic alliance that allowed us to continue our plans for growth and market expansion, and further our commitment to serving contractors better than any other specialty construction product distributor in the industry.

The A.H. Harris team (along with their wholly-owned subsidiaries Kenseal Construction products and HarMac Rebar & Steel) and HD Supply White Cap have now joined forces to serve you even better. It’s a winning combination. Both companies share the same core values, uncompromising commitment to excellence and a deep understanding of the challenges and pressure you face daily on the jobsite. Now, together we’ll be delivering the best of both worlds. You’ll benefit from increased resources, strong manufacturer relationships and a host of new locations to support your efforts wherever projects take you. During this transition, count on us to work diligently to integrate service and credit to keep it business-as-usual for you. It’s an exciting time for all of us. We look forward to seeing you on the jobsite and in the store.
