Not too far back, I needed to hire a cleaning service company to clean up a stores interior when all the work was competed. Upon the contractors finishing their work the service techs came in and took over the cleaning and service aspect of what my company was incharge of completing. When my work was finished they made the job completion easy and worry free. To me this is VERY important, because how I leave a job site is a major contributing factor in me getting yet another job from the chain stores main office.
