Our Story

Built on proof.
Driven by relationships.

Continental Cleaning was founded in Dallas–Fort Worth on a single idea: the rooms that matter most deserve a contractor who can prove the work. We earned our reputation in healthcare cleanrooms, where USP 797/800 compliance is measured on the surveyor's clipboard, then carried that same discipline into mission critical data centers and active construction sites.

Today we are one of the fastest-growing critical environment EVS providers in the United States, with crews deploying nationwide for data center final cleans, ISO 14644-1 certification, healthcare cleanroom programs, and post-construction turnover. What hasn't changed is how we work: clean is a number, not an opinion, and every client gets a team that genuinely enjoys taking care of them.

Our Mission

Continental Cleaning exists to deliver a Better Clean that protects people and places through unwavering commitment to Better Safety and Better Health in every environment we serve.

The Continental Creed

Three promises. One standard.

Three promises we can be held to. Ask any crew on site what they mean — you'll get the same answer.

01 / 03
Better

Safety.

Nobody gets hurt, and nothing gets damaged.

Our crews walk into energized halls, live patient corridors, and active job sites. Every one of them is trained for the room before they step into it — NFPA 70E discipline around gear, ESD control near hardware, escorted access where it's required.

  • Crews trained per environment, not per contract
  • NFPA 70E and ANSI/ESD S20.20 protocols on live equipment
  • Zero-damage record across mission critical work
02 / 03
Better

Health.

The room is part of the treatment.

In a USP 797/800 cleanroom or a hospital pharmacy, the environment is part of patient care. We run sporicidal and EPA-registered disinfectant protocols aligned to Joint Commission and TSBP expectations, and we document every visit so your surveyor sees the proof.

  • 100% client survey pass rate (Joint Commission & TSBP)
  • USP 797/800-trained, ISO 7/8 gowned technicians
  • Survey-ready documentation and audit trail on every visit
03 / 03
Better

Clean.

Clean is a number, not an opinion.

We don't say a data hall is clean — we certify it. Particle counts, ISO 14644-1 classification reports, and photo documentation turn a subjective walkthrough into a measurable deliverable your commissioning agent and owner can sign off on.

  • ISO 14644-1 Class 8 cleaning & certification packages
  • Particle counts and photo documentation on turnover
  • HEPA filtration and cleanroom-grade materials where the room demands them
How We Work

Four steps. No surprises.

The same method on every project — a multi-hall data center final clean or a monthly USP 800 cleanroom cycle.

01

Assess

We walk the site, review the drawings and specs, and price the work from the real risks in your environment — not a square-foot guess.

02

Plan

Before the first technician arrives, you get a written plan covering sequence, crew, approved chemistry and equipment, safety requirements, and the standard each area will meet.

03

Execute

Trained technicians perform the work to that plan with the right methods for the surface — HEPA filtration, low-moisture techniques, and cleanroom-grade materials where the environment demands them.

04

Verify

We inspect our own work first, using checklists, particle counts, and photo documentation. Nothing is turned over until it meets the specification.

What Sets Us Apart

Why clients stay.

Critical environment cleaning is a trust business. These are the reasons data center operators, general contractors, and healthcare systems keep Continental Cleaning on the roster.

01

An industry-leading safety record

Zero incidents is a deliverable, not a slogan. Crews are NFPA 70E- and ESD-trained before they enter a live hall or an occupied patient corridor.

02

Relationship-driven, and we mean it

Over 90% of our clients stay with Continental Cleaning for their EVS services. We obsess about our customers because we genuinely enjoy taking care of them.

03

Proof, not opinion

ISO 14644-1 certification reports, particle counts, photo documentation, and survey-ready audit trails on every project.

04

100% survey pass rate

Our healthcare clients hold a 100% survey pass rate with the Joint Commission and the Texas State Board of Pharmacy — our protocols are built for the surveyor's clipboard.

05

General contractors, data center operators, and health systems keep inviting us back to their next RFP — and to their next region.

Training Standards

Trained for the room
before we enter it.

Mission critical environments are unforgiving — energized gear, live hardware, and contamination limits that carry real consequences. Every technician clears the relevant training before they step onto a site, and we invest in continuous education as standards evolve.
