About Bluestone Construction

Bluestone Construction Services is a privately held commercial contracting company headquartered in West Chester, Pennsylvania. We specialize in educational, healthcare and commercial facilities, but have many clients outside our specialization such as museums, commercial kitchens and multi room housing. We are proud to have a list of repeat customers for additional large projects and smaller maintenance type projects.

With over 75 years of combined experience Dennis O’Flynn and Stan Shewaski are “hands-on” owners. They are invested in each project from the estimating stage to final turn over. Bluestone works with a combination of union, non-union and minority subcontractors depending on the criteria of the project. We have experience with prevailing wage projects. We are a bondable company.
