This porch was built next to my house, but they never put walls on the crawl space (of the house itself), behind that porch.
The crawl space on the rest of the house is made from 2x6s nailed to the posts which support the house. The 2x6s run horizontal, and are covered with metal siding (pole barn metal), which goes 6 to 8 inches into the soil. Apparently they built this porch before they put the siding on the house crawl space, so that portion of the house is wide open.
Ok, it's not "Wide open", because they built this porch from treated framing, put deck boards on top, but also put these deck boards on the sides, down to the soil. However, they left an opening to get under this porch, which I temporarily covered with plywood, using a few screws so I could remove it easily.
While this partly closes things up, there are the gaps between the deck boards, Plus they did not put backs on the steps, so if I look between the steps, I can see right under the house. Besides letting cold aur under the house in winter, it lets critters get under the house, and whatever rain and snow that can get down there.
The plan is to move the porch about 3 feet away from the house, put the metal siding against the crawl space wall, and move the porch back where it was.
This should be fairly easy, because the porch is free standing and not attached to the house at all. The porch just sits on some solid concrete blocks, an it's only 7x11 feet. (steps included). But that small porch is built so well, that it must weigh close to a ton. Last weekend I had a friend over and we were going to lift it. We could not even lift it a quarter inch.
Normally, I'd get my tractor over there and easily move it, but because of the lay of the land, a retaining wall, a fence and other stuff in the way, that is not possible at all. I cant even get the tractor on the other side of that fence and use a chain, because there is no way to get any machinery over there. There are no trees or solid objects to connect a come-a-long to either.
So, it all comes down to muscle power, or some sort of jacking method. But jacking it up means another problem. Since the sidewalls go to the ground, there is no way to get a jack under the sides. The only place to jack it, is under it from that opening and that would mean the jack would only be in the center of the deck. Plus the deck floor is close to 4ft off the ground and my floor jack dont go that high. Of course I could pile wood blocks on top of the jack, but I dont want to be under there if the blocks tip over, which is very likely with that many blocks.
So, I'm at a total loss how to go about this.....
Yes, I did have one thought, and that was to see if I could find someone with a pulling horse. (Around here there are guys that have them). A horse could get in there, by going thru the woods, whereas a tractor cant. The horse could probably move that porch easily AWAY from the house, but the horse cant PUSH it back when I finish my work. So, that would not work.
Then there was the thought of finding about 6 guys to lift the thing. I'm sure 6 guys could, but because those side walls go to the ground, there is not enough space for that many guys to grab it. Another NO....
So, I'm back to square one ????????
