Cleaning is a Science.
We Treat It That Way.

"Knowing what to clean is not the same as knowing how to clean it. The difference comes down to knowing your materials, your chemistry, and your craft, and we built this company around that difference."
-- Wilson & Farr Cleaning Solutions

4 Stages. Every Space.
No Exceptions.

Before we pick up a single tool, we already know the condition of the space, which products we're using, and what order the work happens in. Here's how that breaks down.

1

ASSESS

Environmental Analysis

Every job starts with a walkthrough. We note surface types, how heavy the soiling is, any contamination risk, and anything unusual about the space. Everything that follows depends on getting this step right.

2

SELECT

Chemistry & Equipment

From the walkthrough, we choose the cleaning agents, dilutions, and equipment for each surface. A product that works on tile can damage vinyl, so we don't carry one default product for everything.

3

APPLY

Controlled Execution

We work high to low and from dirty areas toward clean ones, which prevents cross-contamination and means nothing gets missed. Products are given their proper dwell time instead of being wiped off too soon.

4

CLEAR

Quality Verification

Before we leave, we check each area against the notes from the walkthrough. Anything we flagged on arrival has to be resolved before we pack up. We'd rather catch a miss ourselves than hear about it from you.

The Standard Applied
Across Every Surface

Trained to a Standard,
Not a List

A task list tells you what to do. A standard teaches you why, how, and with what, and it holds you accountable for the result. Here's how that plays out in practice.

Wilson & Farr

A Professional Standard

  • Independent accreditation from ISSA, GBAC, and BBB
  • Surface-specific chemistry selected per assessment
  • Formal training in cleaning science and infection control
  • 4-stage methodology applied consistently across all jobs
  • Quality verification before leaving each area
  • Transparent scope, so you always know exactly what's included before we begin
  • Coverage of carpet, windows, floors, and specialty surfaces
Checklist Approach

Task Completion Only

  • Training focused on task completion rather than cleaning science
  • General-purpose products applied across all surface types
  • Limited emphasis on chemistry, dwell times, or surface science
  • Success measured by task completion rather than verified outcome
  • Quality review typically relies on client feedback after the fact
  • Scope of service may be limited by training or operational guidelines
  • Specialist surfaces may fall outside standard service scope
