The One Service is a locally-owned commercial cleaning company serving San Antonio and surrounding counties. Our purpose-built crews deliver routine janitorial, deep cleans, floor care, and specialty services with the kind of consistency most companies only promise.
We built this company around one principle: clients shouldn't have to manage their cleaning vendor. When you hire us, you get a single point of contact, an on-site operations manager, and written status updates — so you always know the job is getting done.
From the first walkthrough to the final sign-off, we keep the process simple, documented, and transparent — because that's what your facility deserves.
We walk your facility together, learn your priorities, and build a custom scope that matches your budget and frequency needs.
You receive a clear, itemized proposal with scope, schedule, and pricing — nothing hidden, no surprises at invoice time.
Our crews work from documented checklists with on-site supervision and daily quality checks, and you get written status updates.
The One Service has handled our facility for years and never missed a beat. Clean, on time, and communication is second to none.
Their crews show up prepared, follow the checklist, and their supervisor picks up the phone every single time. That's rare.
Proactive, professional, and consistent. Zero issues across multiple seasons — the kind of reliability that lets us focus on our actual job.
Tell us a bit about your space and what you need cleaned. We'll get back to you within one business day to schedule a walkthrough and written estimate — no pressure, no obligations.
