Preparing to Clean Your Facilities


Safety and Security.  A motto to live by. 



Diversified Building Services, LLC is committed to providing a safe environment for our employees, our customer’s employees, and the members of the general public who may enter your facility.

We partner with our customers to develop site-specific safety information and training for our service staff.  This safety information and training is used in conjunction with our standard safety training to create a program tailored for your facility.


Standard Safety Program consists of:

Safety Overview
On site and/or Safety Training Video
Online Blood-Borne Pathogen Training
MSDS/Right to Know Training
Emergency Procedures Training (site specific)
Full Compliance with all OSHA Guidelines
Our supervisors are all OSHA 30 certified



Security is a very serious matter. With that in mind, Diversified Building Services, LLC takes the necessary measures to assure our customers peace of mind while our staff cleans their facilities. The backbone of this program is employee screening. We utilize a third party firm to provide a seven-year criminal background check for all new employees.

Diversified Building Services, LLC will work closely with your personnel to make certain we are in compliance with all lockdown and alarming procedures. Our employees are instructed in the proper use of keys, locked and/or secured areas, and any special alarm systems or procedures used in your facility.
