I was reviewing the estimate from my pool installer, and he added $50 for installing my steps (The Step II by Access). It seems to me that this should be an easy install, and shouldn't take much longer that the ladder install (that he wouldn't have charged for if we had gone that way). Am I missing something? For $50, I am thinking I will tell him to just leave the steps in the box and I will do it after he is done with the rest. Is this install really as easy as I am imagining?
