    Granted that you had a ” tight fit ” there amigo. Try crawling a double wide and come face to face with a Western Diamondback. I’ve caught 2 of them under my house while doing repair work. Where I live you have to watch out for the Critters. Scorpions are not fun to lay on while working either. Nice video, thanks for posting.

    I live in north west AZ and I’m stressing the fact of our Diamondback issue. We are infested with coon tails and Mohave greens. They slither on a bed of scorpion around here.

    Thanks for posting! Any thoughts on properly installing bellypan insulation for the sake of moisture control? I could get the batts/plastic up there, but I’m worried about moisture buildup inside the insulation. I also feel like my place is so poorly insulated anything I invest in insulation I’d be getting a better payback for increasing my heat production instead, especially since I can’t insulate the ceiling (the most important high-R value area).

    the area “above” the insulation i installed under the floor is heated. The moisture problem the home owner had was from leaky plumbing in the floor, not condensation. The area “under” a mobile home is cold and protected from the weather by a skirt and un insulated to prevent this.

    very dangerous blocking to hold up the trailer(mobile home).. cement blocks have no strength when placed with the holes on their sides, all their strength in when they are place with the holes verticle

    i did not build the trailer, nor was a contracted to fix anything but the floor insulation, and water damage, but the trailer has been on these mounting points for 30 years, mr home owner neither warranted replacement or afford to do so. i did the floor insulation as requested. thnx

    lol, everything about the crawl space under a mobile home or trailer says work, Never have i been under one of these floor repair projects, especially an insulation job and had so much fun ;P I swear they all look the same once you get past the skirt ing.

    You are correct, but this was done before a lot of laws went into effect. You can tell that because there not double blocked all the way up to the frame. We just went through all of this a few years go in WI. Also note though, 20,000 pounds with 28 piers, then each pier is only holding just over 700 pounds. Im guessing in weight and number of piers but you get the idea.

    Yeah I know what you mean..I used to do House Leveling ;/ But I would prefer working under a mobile home any day than a pier and beam home.

    A million thanks! Your video is great and has been of tremendous help to me. I had a broken drain pipe ruin a ton of insulation under my trailer. Of course the plastic sheeting had been ruined also. Repair estimates from the big local insulation company were astronomical. Three kids and my not working is making $ tight. Thanks to you, I’m doing the repair myself and the “insulation blanket” technique is genius.

    Unemployed? Looks like you can go to work for your self and make some dough by doing it your self :). All you need to do is scrounge up the $ for the insulation and plastic. Probably $300.00 or so.

    I love the “lacing” technique! A critter is living under my mobile home in NJ .Any ideas on keeping the skirting opossum proof?

  22. ROCKNTV1 June 15, 2013 at 11:23 am #

    you could try crushed stone as a perimeter to deter them from digging under,maybe..

    great Idea! nice job

    @ROCKNTV1, Along the metal beams, how did you seal that up? Your method is great, but I cannot figure that last part out. (this being to keep out the critters and such.)

    hi, most MOBILE HOME FLOOR INSULATION of this vintage was called an insulation blanket, layed down during construction, and was NOT at all protection from animals, you need to keep those out from under with a good trailer skirt. There is a diagram i made during the how to, i did it video of FIXing MOBILE HOME FLOOR INSULATION. This i realy just how to insulate a mobile home, other issue must be delt with accordingly. )
