  1. I recently bought a 1981 manufactured home Can I ad insulation and foam boards with out removing the original belly wrap,as an extra insulation.

  2. First of all, thank you for your work on this site, I really appreciate all the helpful articles and the candor. My question is about the term belly ;oarc. I have a 1976 single wide BUDDY and live in Northern Nevada. My belly board is actually a board. It’s like a pressed board. It seems to serve as a vapor barrier and rodent barrier, although I’m not sure how effectively. I have all kinds of openings which I’m working on depending on where it is. But the one problem I have is all along the perimeter the board has pulled away from the outside joist. Its been attached with large staples most of which were just improperly installed, meaning the staples didn’t make contact with the wood. Supposedly this place was made after the 1st HUD guidelines, but I really wonder
    The workmanship is shoddy to say the least, on top of the plethora of prior owners doing really weird things, I’m dealing with one problem after another. Any ideas? Oh and the space between the ductwork and the bellyboard essentially there is no space so the insulation is smushed in there which reduces the r factor. So I’m not sure what to about that . The prior owners put 3 inch screws to attach new flooring and went right through the heating duct. They also moved the toilet and placed it right in the middle of the duct. They never even sealed the holes so the first year I was hear I was freezing but it was warm down below. I sealed it up and the next year my pipes froze! And only then did I realize the shutoff valve is under the house. Yes, the main is down there too, but so is an additional shut off valve next to the toilet. But no valve above the floor, thank God the toilet doesn’t overflow.
    I really had to laugh. What an idiot! Yes! I am a perfect example of what not to do when buying a mobile home for the first time and never having lived in one. I had no idea what to expect and what to look for. I didn’t even know how to get under the trailer, let alone look under it prior to purchasing it.
    But it is a roof over my head. And it is mine. And affordable. I’ll never be able to afford owning a house, let alone market rent, so I really don’t have any regrets.
    Any information would be appreciated

  3. Thanks for the article. This site has helped me so much. I jumped the gun, buying our first (mobile) home. I didn’t realize how much work I was in store for lol… I have a question: My mobile homes is from The 80’s. The belly board is good until you get to one side of the mobile home. It is torn and hanging down the side of the home. I bought some tape-like material made for it. Are there any other steps I need to take, besides just pulling up that sagging/hanging side and attaching it again?

  4. Thank you, I’m really learning some great information from fine folks like you!! I recently purchased an older 14X48 mobile on its own land that needs a lot of work before I can move into it. I’m doing most of the work myself and all of this info is invaluable!!

  5. I’ve been dreaming of mobile home living for a very long time and enjoy your website soooo much! Thank you for providing such useful information, well thought-out and thorough articles. Because of southern California park prices, I know what I buy will be older and possibly need repairs. Hopefully, not too extensive, but I understand things don’t always present themselves during inspection. I first got hooked on your site because of the makeovers, but found you provide so much more – things like this subject of belly boards! LOL, I know me, and I know I won’t be underneath doing the work.

    Thank you so much for everything!

  6. Please help, we recently had a water pipe burst and run into the belly board and soak the insulation. what are the steps to remedy correctly.

    1. Hi Rhonda,

      It really depends on how wet the insulation got. If it’s salvageable you should be able to use large fans to dry it out and then seal the belly board back up. However, if it was already old and then got soaked it may be easier to just replace the insulation. You’d certainly get better r-value with new insulation and probably lower your heating and cooling costs in the process.

      I’d take this opportunity to go ahead and replace the insulation if it were me (assuming I had the money to spend). Best of luck!

  7. I desperately need help in Northeast Oklahoma with a Solitaire doublewide that had the roof completely ripped off my straight line winds – long story but I have a new roof but it is like my home is splitting down the middle along the marriage seam. I can’t find anyone to help with re-leveling or whatever it is that I need. Has anyone else had this problem and if so can you give me any advice?

  8. Had a flood in our mobile home and the underbelly was sliced to let the water out and the insulation got wet.
    Can you recommend someone in the Middle River, Maryland 21220 area that are experienced to do this type of repair work. Insurance has given us an estimate and is paying for the repairs. Just don’t know where to start finding a professional experienced person to do the work. Thanks so much for any help you can give.

    1. Hi David,

      I cannot personally recommend anyone but maybe a reader will see your comment and help. I am working on getting a national directory/review site for professionals that will work on mobile homes but it’s not ready yet.

      I would call your local mobile home supply store or even local dealerships for recommendations. Best of luck!

  9. Hi Crystal, I have enjoyed reading your articles! Today belly board repair suggestion, blue tarps…..thanks much and more. That is better than nothing.

    1. Hello Ms. Daryl,

      Ideally, you need to use the black polyethylene sheeting but if you don’t have anything else, use what you can. Polyethylene sheeting can be expensive so it will work till you can save up. Thanks!

  10. Thank you so much for this article. We desperately need repairs on our ductwork, insulation and belly board. We have basically gutted and rebuilt most of the inside of an older mobile home and are over budget. Since day one I have been saying that we absolutely need these repairs but no one who has worked on our place seems to understand. Even a contractor who regularly works on mobile homes in our area seems baffled as to what needs to be done. I love what we have done inside and want to protect it. Thank you. Any suggestions on finding someone who can do this work?

    1. Hi Kim!
      Glad it was helpful for you. I wasn’t really aware of the importance until I kept reading all the manuals and books. Every one of them stressed the importance and it makes sense, you don’t want moisture or critters to reach the insulation and all the other stuff under there.
      Unfortunately, it’s really hard to find anyone that is willing to work on mobile homes and especially if it’s a job that requires going under a mobile home. A handyman or a manufactured home installation company are probably your best bet.

      Best of luck! Let me know how it goes!
