Water is one of the most damaging forces on earth and can destroy a home quickly or slowly. Repairing water damage in homes is a multimillion dollar industry in the US. Instead of having to repair water damage after it occurs, this article will help you understand moisture problems in manufactured homes.
HUD produces some extremely in-depth resources via PDF, bound book, pamphlets, and ebooks on a variety of housing and community topics. There are only a handful of resources for manufactured housing but what they have produced is very informative. One of their resources is a PDF called MOISTURE PROBLEMS IN MANUFACTURED HOMES: UNDERSTANDING THEIR CAUSES AND FINDING SOLUTIONS. We’re going to pull the most valuable information from it and try to make it easy to digest. Ready?
Moisture problems in manufactured homes can begin when excess amounts of water are dumped into the air by common household activities like cooking, bathing, heating, and even mopping. So everything we do damages our homes. Nice.
Luckily, using ventilation fans during these fun daily activities will help a ton but be sure you keep them on for a bit after you are finished with your activity so the fan can pull as much moisture from the air as possible.
I owe my algebra teacher in 9th grade an apology because I have had to use her fancy formulas in real life and way more than once. There is a LOT of math used in construction and blogging. Who knew?
I don’t quite understand it all but a central air unit that is too large for your home can actually cost a ton more to cool it, and it can create a lot of moisture in the air that can damage your lovely home.
HUD states that “Equipment that is too large will turn on and off frequently, allowing humidity to build up indoors” and they seem to know what they’re talking about most of the time so we’ll leave it at that.
Carbon monoxide will kill you so you really should reduce every chance it has to get to you. There’s another reason you need to vent your fossil fuel heaters: they can produce a lot of moisture into the air.
HUD writes that “about a gallon of water vapor is released into the air for every gallon of fuel consumed. This is a significant source of water vapor that can quickly cause damage.”
In manufactured homes, your heating and cooling are distributed through ducts in the floor or ceiling. Covering or closing these registers can create an imbalance in the system which, in turn, creates cold spots which increase the potential for moisture condensation.
In (some of) HUD’s words: if warm air cannot enter a space (whether it be a room or closet) the air will get “cold enough to significantly raise the relative humidity level in the room, supporting mold growth.”
Apparently, your heating and cooling filters do more than keep cat hair down? HUD says they can “interfere with an air conditioner’s ability to remove moisture from the air, and in some cases interfere with condensate drainage.”
Filters should be cleaned or replaced a bit more often than most of us realize. HUD recommends that we consider using pleated filters for better dust control and better dehumidification.
The list above is just a start. Unfortunately, there are many more sources of moisture that can damage your home:
Site prep and grading is so very important when it comes to a healthy and longlasting manufactured home. It doesn’t just stop at installation, as an owner you need to be on the lookout for puddles, leaks, and other issues that can damage your home.
To put it simply, there should be no standing water under or around your home. Sometimes, that means you need to install complex drain lines installed by professionals and sometimes that just means you need to dig a little ditch. Let’s always hope for the latter.
Under that gorgeous manufactured home of yours, there should be a cement slab, gravel, or polyethylene sheeting that completely covers the ground so that moisture from the ground can’t become condensation that reaches your home.
Your manufactured home’s skirting can also be the source of moisture issues in your home. Warning: more math stuff. Did you know that there are formulas that should be used when designing and installing skirting on your home? You need 1 square foot of ventilation for every 150 square feet of skirting. You also need to have vents within 3′ of every corner, so you don’t get dead air pockets.
Your dryer vent can cause moisture and fire. Without proper maintenance it could 1. catch fire, or 2. cause condensation. Crazy, huh? You want to make sure it is properly vented outside of the crawlspace.

Of course, you want to make sure your plumbing pipes aren’t leaking. Even a small leak can create a HUGE problem over time.
Apparently, the writers of this HUD PDF has never been to Florida in August. Setting the air conditioner below 75 just doesn’t cut it sometimes.
“Keep the thermostat set at or above 75°F in the summer. In high humidity climates, a lower setting could cause water to condense inside wall cavities.” Umm, OK, HUD, whatever you say…….
If you are like me and don’t see yourself keeping a thermostat above 75 during August in the South, it’s probably a good thing to learn how to recognize moisture problems in your manufactured homes.
Big moisture problems start as small ones, and any moisture problem is more easily cured if discovered early on.
The following are warning signs of possible moisture problems:

These tips are really just the tip of the iceberg when it comes to moisture problems in manufactured homes. If you are seeing drops of water dripping from your ceiling or running down your walls or windows, you want to start the hunt to see what is causing it and how it can be corrected. Hopefully, it isn’t too serious.
