The Retainer Model
Commercial Exterior Cleaning — On Retainer
Lock in your schedule once. We handle the rest.
Why “retainer” — not “subscription”
“Subscription” reads like a consumer product. “Retainer” reads like a professional services agreement — and that’s exactly what this is. Property managers, HOA boards, and NNN tenants already operate in a world of vendor retainers: legal retainers, landscaping contracts, HVAC maintenance agreements. KECC fits directly into that model.
What a retainer means with KECC
- Scheduled service dates are locked in advance.
- Pricing is fixed and predictable — no surprise quotes.
- KECC is your exterior cleaning vendor — not a company you re-hire each season.
- One agreement covers everything: scope, frequency, access, and invoicing.

From the Founder
A Note from the Founder.
“Thank you for taking the time to consider Knox Exterior Care Co.for your property — it means a lot to us. There are plenty of vendors competing for your exterior maintenance work in the Knoxville area, and we don’t take your attention or trust lightly.
I built KECC to be the single, accountable team that property managers, HOA boards, and commercial owners can lock in on retainer and offload their exterior cleaning on to. Commercial property is our specialty — but homeowners who want that same professional standard are welcome too. We look forward to speaking with you!”
