GreenTerra

Commercial Janitorial & Office Cleaning · San Francisco & Beyond

Commercial cleaning, engineered to a measurable standard.

Since 2005, GreenTerra has been built on one conviction: skilled work can be measured. Every building gets a documented standard — so you see exactly what’s done, where, and how often. The work, made visible.

How it works

A measured standard, from day one.

Most vendors quote your building by eyeballing it. We measure it — so the standard is clear before we start, and provable after. Tap each step.

01 — Walkthrough & assessment

We walk every space with you: square footage, surfaces, fixtures, traffic, and the frequency each area actually needs. Nothing is estimated from a floor plan or a photo, so nothing gets overlooked.

No padding. No guesswork. A standard you can take to ownership.

The difference

A standard is only as strong as the system behind it.

Anyone can promise “clean.” Here’s how we make it hold — so month twelve looks like month one.

01 — Our people

Trained professionals, never subcontractors

The same accountable faces, week after week.

Every GreenTerra cleaner is a direct-hire W-2 employee — background-checked, bound by confidentiality for secure access, and trained continuously in workloading, sanitation, and certified custodial procedures. You get the same trained people in your building, not a rotating cast.

02 — Our oversight

Layered accountability, one name

No runaround, no finger-pointing.

Your account runs on three layers, with a single owner at the end of it — so there’s always one person responsible for the outcome.

03 — Cleaning you can verify

Clean, defined and proven

Not left to opinion.

Staffing is workloaded to established industry cleaning-time standards so the hours match the real work, cleanliness is held to a recognized facility standard (APPA Level II), and every visit is documented through digital inspections and QA you can review.

04 — How we communicate

You’re never left wondering

Accountability as a habit, not a promise.

A written response to any concern within 24 hours, quarterly review meetings, and a shared digital log of completed work and resident feedback keep everything in plain sight — so nothing quietly slips.

Fewer complaints. Lower liability. Audit-ready. That’s the difference.

Health-First Cleaning™

We clean for health — not just appearance.

Health-First Cleaning™ is our protocol for removing what you can’t see, not just what you can. Color-coded tools keep restroom and kitchen contaminants from ever reaching a desk or a door handle. Disinfection is targeted where it actually matters. And the products are certified-green — effective on pathogens, gentle on the people in the building.

Color-coded microfiber
Red for restrooms, blue for glass, yellow for kitchens — cross-contamination stops at the color.
Targeted disinfection
High-touch surfaces — door handles, elevator buttons, shared equipment — get hospital-grade disinfection; low-touch areas get cleaned, not over-chemicaled.
Certified-green products
EPA Safer Choice and Green Seal — safer for occupants, staff, and the building.

“I started this company because I believed cleaning could be a skilled trade — measurable, documented, and built to hold. Twenty years later, that conviction drives every walkthrough, every standard, and every account we keep.”

Common questions, straight answers.

Every proposal is built from a measured walkthrough — we calculate labor hours by area, surface, and frequency using industry cleaning-time standards. You get a transparent, line-item price based on the real work, not a lump estimate.

No. Every cleaner in your building is a direct-hire W-2 GreenTerra employee — background-checked, trained in-house, and bound by confidentiality. You get the same team consistently, not a rotating cast of subs.
