Big League Clean’s response to that review: “We are glad our school cleaning services for you have been to your expectations! We appreciate the opportunity to work with you!”

Six months in. Extremely pleased. Same crew. Big League Clean runs Denver K-12 school accounts the way schools need them run: assigned crew who knows the building, scheduling built around the academic calendar, and an account manager who picks up the phone when something comes up.

Why Denver K-12 Schools Choose Big League Clean

Background-checked crews: same team, every visit

School administrators need to know who is walking into their building. Every Big League Clean K-12 account in Denver runs with an assigned crew. The same people show up on the same schedule. Your staff and students see familiar faces, not a rotating roster of unknowns from a staffing pool.

After-hours cleaning: no disruption to instruction time

Most Denver K-12 accounts run after dismissal, overnight, or on weekends. We coordinate directly with your facilities director so cleaning schedules align with class times, athletic events, and school breaks. Summer and holiday deep-clean packages are planned months in advance so your facility opens on time.

30-minute response during the school day

Urgent requests, including a spill before a parent night or a deep-clean response after a health incident, reach a real person within 30 minutes. A named account manager who knows your building, not a call center.

What We Clean in Denver K-12 Schools

Where We Work: Denver-Area K-12 Schools

Denver Public Schools operates 88 schools across the city, from elementary campuses in Montbello and Green Valley Ranch to high schools in the Highlands and Capitol Hill. Charter schools across the metro include KIPP, DSST, Rocky Mountain Prep, and others concentrated in Stapleton, Aurora, and the Five Points corridor. Private academies in Cherry Creek, the Highlands, and Lowry each have their own vendor requirements and scheduling needs.

We service K-12 accounts across Downtown Denver (80202), Cherry Creek (80206), the Highlands (80211), Aurora (80012), and Centennial and Arapahoe County (80112). Coverage runs the full DPS footprint and surrounding district campuses.

Denver wildfire smoke season runs June through September. Fine particulate from smoke events settles on classroom desks, HVAC diffusers, and high-touch surfaces throughout the building. Our Denver school deep-clean scopes account for this, a detail national cleaning vendors with templated protocols regularly miss.

Frequently Asked Questions

Do you clean K-12 public and private schools in Denver?

Yes. We serve Denver Public Schools district campuses, charter schools, and private academies across the Denver metro. Each account is scoped on-site before any crew is assigned. We tailor the cleaning plan to your school’s layout, schedule, and specific facility needs – DPS campuses, charter network requirements, and private school standards are all handled differently.

Every Denver K-12 account is built around the academic calendar from day one. We map daily service to school hours, identify break windows for deep cleans, and adjust scheduling for events: parent nights, athletic competitions, district inspections. When plans change, your account manager responds same-day and adjusts without disruption.

Cafeterias are cleaned with food-safe disinfectants on all contact surfaces, tables, serving areas, and floors. Locker rooms and gymnasiums receive full disinfection with odor control on every service visit. High-touch surface protocols cover door handles, light switches, shared equipment, and railings throughout the building on every visit, not just on deep-clean days.

Yes. Summer break, winter break, and spring break deep-clean packages are available and strongly recommended for Denver K-12 schools. We schedule these months in advance. Denver schools get wildfire smoke season particulate cleaning built into summer deep-clean scopes – fine dust that accumulates on every surface during Colorado’s June-September fire season that most standard protocols miss.

We are NetVendor verified for commercial vendor compliance and carry general liability insurance and workers’ compensation. Certificates of insurance with additional insured and waiver of subrogation language are available for any DPS campus, charter network, or district that requires vendor documentation.

We are locally owned and operated. Matt Christou and Nash Hutter founded the company and are involved in account management – not a franchise licensee managing from another state. Every K-12 account gets a named account manager with bi-weekly check-ins. The same crew returns on every visit. Our Denver school cleaning protocols account for local factors – wildfire smoke season, high-altitude dust accumulation, and Front Range seasonal patterns – that national franchise templates do not address. Month-to-month agreements. Nothing locks you in.
