$100.00 doesn't get me in the door but if I was there already doing something else, probably gets a half hour to 45 minutes. I expect the carpets to be dirty, (that's why they called us) a lot of carpets are white or off white, we go to every job prepared for the worst. It takes a lot to throw us off our game but it does happen. In those situations, we raise our prices or don't do the job. I have one customer right now that I am trying to talk her in to replacement but she just doesn't have the money so we'll do our best and maybe next year, she will throw them out. Over 30 year old sculptured nylon carpet. I'll take som pics when I do the job
