Welcome to State Line Engineering!

State Line Engineering was founded in March of 2007 with the vision of creating an engineering firm that provides a high level of service with an emphasis on value engineering. John Demos, the founding owner, is an engineering and Surveying graduate from the West Virginia University Institute of Technology. He is a licensed Professional Engineer in Maryland, Virginia, Delaware and Pennsylvania and licensed as a Professional Land Surveyor in Maryland. His 16 years of experience includes all facets of development engineering as well as in the field of residential home design. Mr. Demos has progressed his career from the ground up as his early career was spent working in the field and experiencing first hand the various aspects involved during the construction phase of a project. This provides invaluable expertise in designing cost effective engineering solutions.

State Line Engineering will work closely and effectively with governmental agencies, design professionals, construction firms, and any other project affiliates. We provide a “hands-on” type of project management by being personally involved with each project and providing direct representation for our clientele. Our dedication is a great advantage to our clientele and makes us a valuable part of any project with which we are associated.

Why us?

I hope I can help you with engineering services for your project, whether for a home or business. I am ready to provide an inspection, design, or a professional opinion that fits your budget.

Since 1995, my job as a Professional Engineer has been to gain knowledge and experience.

Call 443-324-1641 now or email us later so we can begin talking about your design and inspection needs.

Thanks for visiting! John P. Demos, P.E., L.S.,M.ASCE
