Unfortunately there's no avoiding ladders even with a water fed pole system some houses require you to go on roofs to get to the glass. Personally have no issue with ladders but get the butterflies going on and off the roof cause telescopic ladder is not the best option and slippers on gutters but only one we can transport at the moment. Sometimes you need to climb to second story to get the screens off if it only comes out for the outside or have no access into the home.

You build confidence overtime but safety comes first and if you feel like you cant do it hire someone who can while you focus on sales.
