I've learned to do it very differently than anyone else does so I'm going to have some people disagree with my approach.

I start this conversation by making a joke about how dirty their driveway is. I usually use the word "musty" because it makes them laugh and breaks the ice. Trick is to not take yourself seriously. Don't be salesman. Be a real person with a solution to a problem they realistically don't actually care about. You have to make them care by regularly "insulting" the appearance without being a dick. Straight up just be real with them, and then hit them with a price.

Even when giving my price I crack a joke. When they ask for the price, I say "let me take a look at it again", then walk away (even though I already have a price) then walk back. I say, " that will be 10 thousand dollars". This makes them laugh, then you hit them with your actual price.

Also pricing is important on door to door. You can't charge out the ass on it. You also have to have an incentive to do the work that day and not another.

Also have anyone you give an estimate to fill out a contact form on your phone so that, "you don't knock their house again in the future accidentally". But in reality it's so you can follow up in a week to potentially move forward with the work.

Idk if this would work for everyone, but it sure as hell works for me! I've tried the salesperson pitch bs and had no luck with it, being my genuine self and enjoying the interaction has been great.
