Cleaning is a Science.
We Treat It That Way.

"Most cleaning services follow a task list. We follow a methodology — because knowing what to clean is not the same as knowing how to clean it. Surface science, chemistry, and controlled application separate a clean that looks done from a clean that is done."
-- Wilson & Farr Cleaning Solutions

4 Stages. Every Space.
No Exceptions.

Our process is consistent — not improvised. Before we pick up a single tool, we already know the condition of the space, the correct chemistry, and the right sequence.

1

ASSESS

Environmental Analysis

Every engagement begins with a thorough assessment of the space. Surface types, soiling levels, contamination risk, and special conditions are all documented before any cleaning begins. This step drives every decision that follows.

2

SELECT

Chemistry & Equipment

Based on the assessment, we select the appropriate cleaning agents, dilutions, and equipment for each surface. Not a default product for every job — the right product for this job, validated by cleaning science.

3

APPLY

Controlled Execution

Application follows a structured sequence designed to prevent cross-contamination, ensure correct dwell times, and address every surface in the right order. High to low. Dirty to clean. Nothing skipped.

4

CLEAR

Quality Verification

Before we leave any area, we conduct a quality check against the original assessment. What was identified on arrival must be resolved on departure. This is our internal accountability measure — not a customer complaint process.

The Standard Applied
Across Every Surface

Trained to a Standard,
Not a List

A task list tells you what to do. A professional standard teaches you why, how, and with what — and holds you accountable to the result.

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
  • No restriction lists — every area addressed properly
  • 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
