On another note, it's A-M-A-Z-I-N-G how fast your dogs are growing. You will definitely need a bigger mat!
Looking forward to more updates.
If you are stripping up your decking, you REALLY should use either Rain Escape or DekDrain. Both of those systems go over the top of your joists, have the cheapest materials, and allow you to do any normal wiring, lighting, and ceiling underneath that you want. No question. Do that.
All of the other systems lower the bottom of your ceiling and usually ARE the ceiling. They also have restrictions on where you can put lights in, and any hole you put could be a possible leak. I really wish that stripping up my deck was an option. Due to my screened-in room above half of my deck, it would cost way too much for me to do that. It would be the nicest looking option but also the costliest. Other systems I looked at were ZipDeck, UnderDeck (or UnderDeck Oasis), DrySnap, DrySpace, and American DryDeck. If your deck is a standard square, and doesn't have any odd middle columns or beams, then most under-deck systems would have a straight forward install. American DryDeck was rated well for an underdeck system, while I've heard horror stories about ZipDeck. (And DrySnap) As far as the over-the-joist systems, they are both excellent.
I had a guy come yesterday and look at it, and he recommended:
1) I remove the back beam underneath the 1-level part of my deck, as well as the two inside columns. He said there appears to be no reason it is there, and some installers used to put them in no matter what.
(I had recently drilled a hole into my closet and he saw that the house had a 1 1/4" beam across the house to anchor the deck, as well as the 2" beam which the deck rests on on the outside. With that, he said there was no reason for any of the back beams and said if I really wanted to, I could remove them both, but there wasn't much of a reason to do so on the other side since it rested against the house)
2) Once that is removed, and I patch concrete as necessary, he says to just do DrySnap, and do it myself, since he said it appears I am handy enough to do so, though he recommended a 2nd set of hands since pieces are 14' long. But I've read bad things about DrySnap if the installation isn't perfect, and am Hesitant to use this product or do it myself.
Plus he said if I do it myself, he hinted that he wouldn't even bother pulling a permit for just the ceiling fan, but if HE did the work, he would have to, plus he would have to pull a permit for removing that beam since the guy inspecting the fan would probably complain. He also said since I am doing Low-Volt wiring for lights, an electrical inspector might complain about it, even though you don't need a permit for LV stuff.. not that he would, he just said he has seen it happen so it might save a headache if I did it on my own.
He also said if I really didn't want to do it, he could do it for about $15/sf for the ceiling work, but he told me where I could buy the materials for closer to like $5/sf if I wanted to do it myself. Where is BIG when I need him!!! I've never messed with things like flashing before.Edited by damelon - 5/29/13 at 7:55am
