Standards: Old World Building Services maintains CSLB, ISSA, GREEN CLEAN and OSHA best practices on all their work sites.

Systems: Every work site has its own unique problems and challenges. Old World Building Services will develop and implement the right system plan for each and every work site. By combining old world craftsmanship with new age technology, we use the best of both worlds to produce superior results. Feeling a little sick at work?  It could be how your facility is being cleaned. Smelly chemicals and dirty rags can hurt you. Old World Building Services uses a colored code system: blue, green, red and white for different surfaces. The system uses matching spray bottles, microfiber cloths, mop buckets and mop heads. This method eliminates possible cross contamination of surfaces, misuse of chemicals, and possible causing damage to surfaces. Old World Building Services only uses low odor cleaning chemicals or 250-degree steam to clean germs rather than using harsh and foul smelly chemicals.
