Starting this game back in 2007, I would have said that there were too many Junk Removal businesses. However, I never viewed traditional Junk Removal as a viable business model. I considered Junk Removal as a way to sell unwanted items.
So, pricing for junk removal becomes an entirely different animal. That is if the resale is your focus. I had them send me pictures, and I asked if they had things that were worth money. I asked for pictures that showed all the defects.
It was effective, and we still do this today; all of our businesses are equally focused on acquiring new business (demo, junk removal, flooring removal, concrete cutting) and repurposing. Pricing the job aggressively to get it more if there is stuff we can sell!!
Unwanted items that are in the way enough that they just want them gone. That's the focus!
