About W.M. Schlosser

Since our founding in Maryland in 1962, W. M. Schlosser Co. has been a recognized leader in the construction industry.

Specializing in projects for governmental agencies at the Federal, State, and Local levels, we have successfully completed a broad range of projects throughout the Mid-Atlantic region. Our experience includes hospitals, laboratories, schools, apartment buildings, public housing communities, museums, office buildings, wastewater and water treatment plants, pump stations, subway stations, prisons, and industrial facilities, as well as a number of specialty projects.

As a recognized leader, W. M. Schlosser Co. attracts and employs the finest construction professionals in the industry. Continued training and education in cutting edge and state of the art technological advances ensure that our employees stay one step ahead of the ever-changing construction market. Submittals, purchase orders, change orders, punch lists, warranty items and other items are all managed systematically and efficiently. We also maintain a project close out team dedicated to bringing our projects from substantial completion to final completion as quickly as possible.

We encourage our clients to join us in adopting a cooperative, team-based approach to project development and problem resolution. Our goal is always the same: to complete projects on time, on budget and to the satisfaction of all concerned.

Our philosophy on safety is proactive and preventive. Find the accident before it happens! We have a highly skilled team of time safety professionals who dedicate 100 percent of their time to maintaining a safe work environment. Every WMS employee is motivated to maintain and promote a safe work environment.

All of our scheduling is performed in-house utilizing state-of-the-art scheduling systems with the latest versions of Primavera Project Planner to keep our projects on track.

Our experienced Quality Control Department assures that all WMS projects meet the highest standards. We maintain a corporate Quality Control Plan which covers every facet of the construction process. Our QC personnel are among the best in the industry, and therefore we continuously produce a quality product.

One of our proudest accomplishments is our employee retention. Through a focus on employee development and promotion from within we’ve been able to maintain a core staff of long tenured professionals. We start this process at the ground up with our Project Engineers. They start with the company in a 3-4 year rotation through various departments within the organization including: Estimating, QC/Safety and Scheduling. The goal is advancement to Assistant Project Manager at the end of their rotation.

Our entire team is committed to client satisfaction, quality craftsmanship, the safe work environment for all of our employees and construction partners, as well as ensuring the job is completed on time and within budget. Our longstanding partnerships and client relationships are paramount to our continued growth and success!
