What Mr.John does
Mr. John, Inc. is a family-owned portable sanitation and temporary site solutions provider founded in 1964 and headquartered in Pittsburgh, Pennsylvania. The company operates the largest portable restroom fleet in Western Pennsylvania — over 5,000 units serviced by 55 vehicles, complemented by approximately 300 mobile office trailers, storage containers ranging from 10 to 40 feet, and a temporary fencing line launched in 2021. Service offerings also include a tiered portfolio of restroom trailers (Elite Series and Classic 30), septic and wastewater pumping, and ADA-compliant units. Underlying operations rest on a recurring weekly servicing model, a 24-point cleaning procedure, blue additive deodorizer systems, and vacuum-based waste collection routed to licensed treatment facilities; the company holds ISNetworld safety certification and is an active member of the Portable Sanitation Association International.
The company serves six distinct customer verticals — construction, special events, oil & gas (Marcellus and Utica Shale), seasonal facilities, emergency services, and residential — using direct-to-customer sales via phone (800.642.3791), website quote requests, and field delivery, with no intermediary resellers. Revenue is generated through recurring equipment rental fees (typically structured as a three-month initial term with month-to-month renewal), weekly servicing charges bundled into rental agreements, and event-based premium pricing for luxury trailers (which carry a 50% nonrefundable deposit). Pricing is quote-based and not publicly disclosed, with optional damage-waiver fees ranging from $150 to $400 per unit.
Mr. John is privately held, bootstrapped and family-operated since its founding, with no disclosed venture or private equity investment. Under President Michael McCarthy — who acquired the Pittsburgh division in 1985 and grew it from 12 employees to 51-100 — current leadership includes Vice President Chris McCarthy, Director of Finance Alex McCarthy, Director of Operations David Kropf (managing 5,000+ units), and Director of Safety & Compliance Joseph Hatherley Jr. The company operates Tri-Boro Trailer as a co-branded division for mobile office and storage container rentals.

Mr.John competitors and assessment
Company assessmentBroad incumbents
- United Rentals: Largest equipment rental company in the world with a portable sanitation line serving construction and industrial customers. Competes for the same B2B construction site-services wallet at far greater scale and geographic reach.
- ModSpace (now WillScot Mobile Mini): Former standalone provider of mobile offices and modular space that competes with Mr. John's mobile office trailer offering. Wider portfolio and national footprint make it a broad incumbent in the shared segment.
- Waste Management (portable restroom services): Major waste services company that offers portable restroom rentals alongside its core hauling and disposal business. Broader incumbent with significantly larger scale, leveraging existing disposal infrastructure to compete with Mr. John.
- WillScot: Large national provider of mobile offices, modular space, and storage containers — overlapping with Mr. John's Tri-Boro Trailer division. Not focused on portable sanitation, so broader incumbent rather than direct competitor.
Direct peers
- National Construction Rentals: National provider of portable toilets, mobile offices, storage containers, and temporary fencing for construction sites — almost identical one-stop-shop model to Mr. John, operating across multiple U.S. regions.
- Satellite Industries: Leading manufacturer and rental provider of portable restrooms, restroom trailers, and handwash stations. Direct overlap on portable sanitation fleet serving construction and events; broader geographic reach than Mr. John.
- Honey Bucket: Regional portable toilet and temporary sanitation company in the Pacific Northwest. Comparable product mix (portable restrooms, trailers, handwash stations, septic) and comparable regional scale to Mr. John's Western PA operation.
- United Site Services: Largest national provider of portable sanitation, temporary fencing, and site services in the U.S. Directly comparable core offering (portable toilets, restroom trailers, fencing) to Mr. John's, but operating at national scale vs. Mr. John's regional Western PA footprint.
Emerging players
- PolyPortables: Manufacturer and supplier of portable sanitation units, plastic toilets, and related equipment. Adjacent overlap on the portable restroom product side but more focused on equipment supply than rental/service in Mr. John's mold.
Regional players
- AAA Quality Service: Regional portable toilet and temporary sanitation operator in select U.S. geographies. Directly comparable service model to Mr. John but operating in different territories — does not directly compete in Western PA.
