Why Building Managers In Knoxville Call Us
If a building in Knoxville is yours to look after, how it looks lands on you. A good commercial cleaning service should run quietly in the background, and when it doesn't, it costs you hours you meant to spend on something else. Three reasons bring most managers to us.
Problems Reach You First
The trash is full or a restroom is out of paper, and a tenant or a guest tells you before your cleaners notice.
The Quality Faded
Month one was great. By month four the dusting got thin and the same notes started coming back.
You Spend Time Chasing
You call and wait, you text and hear nothing, and you have no record of what the crew did overnight.
We clean offices, medical practices, schools, banks, industrial plants, and more. Our crews cover downtown and the Old City, Kingston Pike, Turkey Creek and the office parks along Pellissippi Parkway.
Forget Cleaning Forever With Our Zero‑Complaint Protocol™
Our proven system keeps your facility ready for staff and visitors, catches issues early, and backs you with the Assett Quality Promise.
Clean building, zero babysitting
Walk in knowing your facility is ready for staff, visitors, and leadership without you sending reminder emails or walking the halls to double-check.
Consistency that doesn’t fade after month three
Facility-specific training, photo-verified checklists, and ongoing audits keep standards from quietly slipping over time. You don’t wake up to a surprise ‘dumpster fire’ a year in.
People you trust with your building and your badge
W‑2 employees only, vetted through multi-step interviews, background checks, and OSHA / safety training, so you’re not worrying about who’s in your space after hours.
Assett Quality Promise
If you ever have to fix a cleaning issue we were responsible for, that service is on us. You shouldn’t have to pay for problems.
Office Cleaning, Janitorial Services and More in Knoxville
No two buildings get the same plan. We start by walking yours, then put the scope on paper. Our janitorial service sticks to a nightly or weekly routine you set, while our office cleaning service keeps desks, conference rooms and common areas ready for the workday. Mix and match them under one agreement.
Office Cleaning
For offices downtown and along Kingston Pike, cleaned after your team goes home.
Medical Facility Cleaning
Clinics and doctors' offices get exam rooms and touch points handled on every clean.
Janitorial Services
A recurring routine, nightly or weekly, mapped out once we have seen your building.
Custodial Services
For warehouses, plants and larger sites out along Pellissippi Parkway.
Day Porter Services
Lobbies, restrooms and break rooms kept up while your doors are open.
Construction Cleaning
Dust and debris cleared after a build-out, before move-in day.

Questions Building Managers Ask Us
Who is in my building, and how are your cleaners vetted?
Nobody from a staffing agency and no subcontractors. Jacob Penley hires every cleaner directly, each one is screened in eight steps, interviews and a criminal record search among them, and each learns the layout of your building before their first night on your account.
How does quality stay up after month three?
Most cleaning contracts sour around the third month, when nobody is checking. Here, each clean is logged against a checklist with photos, a supervisor inspects your space on a fixed calendar, and you receive a brief written summary. Problems in a Kingston Pike suite or a Pellissippi Parkway office get spotted early that way.
What if there's a problem, and how fast do you fix it?
Real names and mobile numbers, no phone menu, and (865) 398-2549 rings this office day or night. When a problem traces back to us, the Assett Quality Promise covers the fix at no charge.
What's included in your janitorial service?
Restrooms, trash, floors, dust, break rooms and the surfaces people touch most, written into a scope after we walk the space with you. Need a daytime porter for a Turkey Creek lobby as well? It goes on the same agreement.
How does switching to a new office cleaning service work?
Jacob's team walks through, writes the scope, trains the crew and picks up on whatever start date suits you. There is no long contract, since billing runs month to month, and week one is free.
Are you insured and compliant, and do you have references?
Yes. OSHA training on bloodborne pathogens is required for every cleaner, and SDS binders and labeled bottles stay current at each site. Jacob Penley can share the paperwork and local references you ask for.
How do I know what was actually done?
Each task on your list needs a live, time-stamped photo before the clean can be closed out, which gives you a nightly paper trail. On top of that, a supervisor from this office inspects the building on a calendar and writes up what was found.
What happens if a crew can't make it one night?
You hear about an absence from us early, before anyone shows up for work, along with how the gap gets filled. Typically a backup cleaner who has already trained on your site takes the shift. The phone call comes from Jacob Penley's office in East Tennessee, never a call center.
