How We Operate

What a long-term contract with DIAMANDI looks like

The systems below are designed to support long-term contract performance.

Consistent, Accountable Crews

Service is delivered by staff held to one documented standard. Everyone who sets foot on your site completes background screening and facility-specific training beforehand.

Documented Safety Program

OSHA-aligned training on a recurring schedule, current Safety Data Sheets maintained on-site, and a documented chemical-handling protocol for every facility type we serve.

Written Service Guarantee

Any deficiency identified is corrected within a defined window at no additional charge, as a written term in every service agreement.

Liability Coverage That Protects Your Property

General liability coverage sized to cover damage or loss on your premises. Certificates of insurance are provided before work begins, with additional insured status, primary and non-contributory wording, and a waiver of subrogation available upon request.

Environmentally Responsible Products

Low-impact, environmentally responsible cleaning products used across service categories, with product documentation available on request.

Predictable Invoicing, No Scope Creep

Your invoice matches your written scope at all times. Any work outside that scope is reviewed and approved before it is billed, so your budget stays predictable from one month to the next.

Who We Serve

Facilities where precision is essential

Every industry below has a different compliance environment. Our protocols are built to fit each one specifically.

Education

Schools and early childhood facilities, where cleanliness standards intersect directly with licensing and accreditation requirements.

Healthcare & Care Facilities

Medical offices and licensed care environments requiring terminal cleaning protocols and compliance-grade documentation.

Government & Municipal

Public buildings requiring contract compliance, transparent reporting, and accommodation of agency-specific screening requirements.

Corporate & Commercial Real Estate

Office and mixed-use properties where consistency across a portfolio matters as much as the standard at any single site.

Private Clubs & Hospitality

Member-facing environments where presentation and discretion carry equal weight.

Multi-Site & Franchise Operations

Organizations that need one documented standard applied identically across every location they operate.

Getting Started

How an engagement begins

Every relationship starts with a walkthrough of your facility rather than a quote over the phone. We assess your space, discuss your priorities, and put a written scope and price in front of you before any commitment is made.

Once an agreement is signed, service begins on a schedule built around your operating hours. No verbal estimates. No surprise charges outside the agreed scope. The proposed scope and price are what you are billed.

From there, the relationship is maintained the same way it started, in writing, with documentation behind every visit.

Common Questions

What clients ask before signing

We start with a base scope built around your facility type, then walk the space with you to confirm priorities, traffic patterns, and any compliance requirements before finalizing it in writing.

A written proposal follows the walkthrough promptly and spells out exact services, frequency, and pricing rather than a verbal estimate.

Through scheduled inspections against a documented standard, service records from every visit, and a dedicated contact who follows up on results.

Yes. Every employee is screened before any site assignment and completes initial and ongoing training specific to their assigned facility type. We accommodate agency-specific screening requirements on request.

A dedicated contact assigned to your account, not a rotating call center, ensures continuity and familiarity with your site.

Both. We work with one-time jobs, short-term coverage, and multi-year contracts on equal footing. Every agreement includes a standard termination clause allowing either party to exit on written notice.

Payment terms are set during your proposal to match your organization's invoicing cycle. Pricing is presented as either a flat monthly fee or a per-square-foot rate, whichever best fits your budgeting process.

No. Any work outside the agreed scope is reviewed and approved in writing before it is added to your invoice.
