man, upselling on flooring jobs is tough, especially when you're knee deep in a luxury vinyl plank install and the customer starts second guessing their choice. i always carry samples of that Coretec or Shaw Resilience stuff to show how adding underlayment can cut down on noise and make the floor last longer. but half the time they think you're just trying to pad the bill, even if it really does prevent cupping over time. saw a thread on r/Flooring where a guy lost a repeat customer over pushing too hard on trim upgrades. anyone got tips on phrasing it so it feels like you're solving their problem, not selling? i've been using the 'what if we added this for better stability' line but it only lands about 60% of the time. oh and that Malco underlayment roller makes demoing old stuff way easier, but that's not helping my close rate lol.
