Re: Parts mark up
When i first started my then partner taught me why we always try to get the GC or homeowner to supply fixtures. doorchime,smokes.
This saved us from being the ones returning broken and defective items and replacing that chime that went bad 9 months later.Since it wasn't ours we could justify charging labor to replace.
More recent, a company i worked for supplied the outdoor ceiling fans on a country club screened in outside eating area.The FL heat proved to be too hard on the plastic blades.As they gradually bent they got out of balance.Now the fun begins.Trip #1 i run the service call and find 2 out of 4 are wabbling badly.Attempt to balance but they won't.Take blade off of worst fan ,as it is easy to see it was bent.Trip #2 return with what was supposed to be replacment blades.Find that the fit any fan blades wont fit this fan.Trip #3 return with 4 new fans same brand and almost same model number but enough differance that they won,t match the good 2.Thinking exchange blades,but that doesn't work as they changed them enough that they wont work.Now remove old fans and install new.The total hours now involved with travel is about 12 plus the time spent going to the big orange.How nice of the mfg.to replace the fan no charge.Labor not part of warranty.We had to eat the labor.
Point is if we supply we must have a markup to cover our butt.
