Yea yea floormaven, I do those all the time. I guess it's great for the pocket book. But your missing the point.
The point is; If the Box stores and every stupid DIY site on the world stopped making it seem like the skill we have is "simple-ness" after years of learning all the different types of floors out there and what you can get away with and what you can't, that potential DIY'er might have hired you in the first place.
It's a damned shame Box stores and DIY sites make it seem so easy when in fact it is not, but could be for a 10 by 10 room as mostly depicted in a dumbass youtube video, but not an entire house with a hallway.
The one I am going to would have made me a couple grand. I am going into to put bandaids on it because now they can't afford to replace it all. The one I did last week, he had the money to pull it all up and reinstall with a vapor retarder as it should have been done.
Moral to the story is; stop trying to help DIY'ers. They just do not comprehend the complexities of flooring installation as much as we do. If you really truly wanted to help them, you would not help them think they can do it in the first place.
Essentially what you guys are doing would be the same as showing a noob green horn helper a youtube video and then letting him loose in someones house. I know for a fact none of you would want to be liable for that, but thats exactly what your doing.
