Built on Reliability. Driven by Standards.
Tier One Cleaning was founded on a simple belief: commercial cleaning should be consistent, professional, and completely dependable — every single visit.
Our Story
Tier One Cleaning was founded in Harrisburg, Pennsylvania by cleaning professionals who were frustrated with the status quo — cleaning companies that overpromised, underdelivered, and treated clients as just another account number.
We built Tier One from the ground up with a different model: dedicated crews assigned to specific facilities, rigorous training programs, and a management team that stays accountable to every client. Today we serve offices, medical facilities, industrial buildings, and commercial properties across Harrisburg and all surrounding counties.
Our growth has come entirely through referrals and renewals — a track record we're proud of and committed to protecting with every facility we serve.
Our Core Values
Consistency
The same trained crew, the same standards, every visit. No surprises, no excuses.
Accountability
We document our work, respond to feedback immediately, and stand behind every service we provide.
Compliance
We stay current on OSHA regulations, EPA guidelines, and industry-specific cleaning standards so you don't have to.
Communication
Your dedicated account manager is always reachable. Issues get resolved fast — not buried in a ticket queue.
