Jeff Peifer founded JPs Contracting in 1992 on the same principles that we still uphold today, almost three decades and thousands of construction projects later: to maintain a client-centered approach to construction while delivering the highest quality craftmanship. Our mission is to deliver superior service for our clients, to perform construction projects on time and on budget, and to keep safety at the forefront for our employees and subcontractors.

Our office staff, project managers, and estimators work diligently day-in and day-out from our office in Castle Shannon. We also employ a crew of qualified carpenters who lend their expertise each day on our jobsites. JPs Contracting has hard-working people on staff who are committed to doing superior work for our clients.

We are very proud of our network of loyal subcontractors and vendors, which is a testament to how well we treat our fellow construction professionals. JPs has also built a long list of repeat clients who represent some of the finest businesses and institutions in the region.

JPs Contracting has maintained an exemplary safety record which is confirmed by our state-certified safety committee and an experience modification rate well below the industry standard. We are also very proud of our strong financial standing and our impressive bonding capacity.

We prioritize industry relationships and professional development and are active members of professional organizations like NAIOP (the Commercial Real Estate Development Association) and BOMA (Building Owners and Managers Association International). We have great relationships with fellow contractors and the area’s finest real estate managers, developers, and brokers.
