You call for a bid from a company you've never dealt w/before. Say you've got X number of windows need replacing. Give them sizes, tell them EXACTLY which brand you want, all specs (triple pane, double, argon, krypton, wood, vinyl, screens, no screens, and whatever else you do and don't want, including all the extra bells and whistles.) The guy gives you a price on the phone w/o even offering to come to your home to see just what he'd be dealing with. Take it or leave it. Period. Only time he'll come out is when we're ready to sign contract - and THAT has to be assured beforehand. IOW, he doesn't come unless he KNOWS we're signing. And his price is fixed. No haggling. No leeway. "My way or the highway" so to speak. I don't know diddly about this guy. Did as much research on him as I could. Got reference names but no way to get in touch and he didn't offer any. Been in business for quite awhile. No complaints listed. BBB certified (big deal as I've found out in the past). But, heck, I'd like to see him in person and ask some (what I consider) pertinent questions that can only be addressed up close and personal in my home. He's never in his office. Always out on a job. Not that he works out of the back of a truck. He has a legitimate office & showroom. Only business manager was available to sit with - who readily admits is clueless about install, product and onsite operations. Would you do business w/an arrogant (IMO) guy like this? My past experience w/ contractors told me that this is not SOP. What's your take? Oh, and he want's 1/2 up front.
