"I totally get that. Here's the thing β we use purified water, not tap water. That means no streaks and no white spots. Your windows stay clean 3x longer, so you actually clean less often. Most customers tell us it's cheaper per year than cleaning every month with a regular company."
"What if we start with just the front-facing windows? We can do those for around $[lower price] and you can see the difference yourself."
"Well, you get what you pay for" or "Other companies cut corners."
If they mention a specific competitor price, don't match it. Instead: "Yeah, we're not the cheapest β but we're the only company in Scarborough using purified water. That's why we can guarantee no streaks."
