Traffic Engineering Services, LLC was founded in 2005 in Burtonsville, Maryland. TES quickly became an industry leader in maintenance traffic control. Fast forward to 2021, TES is proud to now offer porta john services, sign production/installations, as well as concrete barrier attenuator replacements. TES offers services in Maryland, DC, Virginia, and Pennsylvania.

​

In 2020 COVID hit hard and TES responded by

providing sanitized restroom trailers to our

employees. TES saw the growing need for

quality porta-john services during those hard

times prompting the addition of the TES

Sanitation Division. The Sanitation Division

provides quality porta-john rentals and great

customer service.
