Food and surfaces like paper, carpets, and walls are all places where mold can grow. Mold in a mobile home can’t be completely eradicated, but there are steps you can take to minimize its growth.

How To Kill Mold In A Mobile Home

Step #1. Prevent mold growth in your portable house

A 24- to 48-hour response time is required for leaky faucet repairs, as well as for water spill cleanup and object drying. Make sure your clothes doesn’t get wet to avoid the growth of mold.

Step #2. Make sure to keep the humidity levels low

It is possible to measure the relative humidity with a humidity meter, which can be purchased at most hardware stores.

Vents for clothes dryers, dishwashers, and other moisture-producing equipment could be included. A dehumidifier can assist lower the relative humidity in your home.

A free mold examination is also available as a resource.

Step #3. Make sure your mobile home isn’t prone to condensation

Controlling humidity levels is a good technique for avoiding wetness, as stated in the preceding step. When possible, open the doors and windows of the mobile home to allow fresh air in.

When it comes to mobile houses, there isn’t a lot of room for air movement. Because of their modest power, exhaust blowers may not provide adequate ventilation.

Step #4. Turn up heat

Turning up the heat and opening windows in rooms with air conditioning or heating systems will keep moisture in the air and keep it from collecting on surfaces like windows.

Step #5. Check insulation walls

If there is excessive dampness in the walls of the mobile home, you should inspect the insulation. Compression of the wall insulation can lead to cold spots forming.

Air pockets form as a result of equipment in the interior wall pushing against insulation.

For a wall outlet box, you might press it against the insulation itself rather than removing any. Make use of the contractor’s services to get rid of the old insulation and install fresh, properly cut material in its place.

Step #6. Prevent the collection of moisture underneath

The potential for mold growth can be enhanced if this area of the house is not properly sealed off.

Use skirting vents to prevent water from accumulating around the perimeter of your home. Laying down a plastic ground cover will help keep your lawn dry and free of soil moisture.

Step #7. Eliminate extra moisture by installing a dehumidifier

Using a dehumidifier removes excess moisture from the air and saves it in a reservoir for use when needed. According to your space and humidity levels, you require a dehumidifier of a specific type.

Dehumidifiers can remove 30-40 pints of moisture from the air each day if you reside in a high-humidity environment.

What Can I Do To Keep My Mobile Home Dry And Mold-Free?

In addition to roof leaks, there are other potential sources of moisture in the home. Moisture can seep through a mobile home’s floors, walls, and ceilings.

Absorbent materials like insulation and drywall accumulate water over time. Cooking and bathing in the home might lead to the accumulation of moisture.

Repairing water damage that has already occurred, such as mold development under a window sill or a soft area in the floor due to wood rot, is more expensive, so don’t put it off. Renovations and lifestyle adjustments can be used to reduce the amount of moist air in a home, which can help avoid mold and mildew.

What To Wear During Mold Removal?

Mold and its spores provide a health danger to everyone who comes into contact with them. Make sure you have the proper clothing to prevent mold infestation.

Mold removal requires the use of an N-95 respirator, safety eyewear with no vent holes, protective gloves, long-sleeve shirts, pants, and work boots. If you’re removing mold from your home, you’ll need to wear a respirator.

Use a dehumidifier to keep mold at bay and keep the air fresh and dry. Using a dehumidifier, you may reduce the humidity in the air. Indoor humidity levels should be between 30 and 50 percent, according to guidelines.

Tips to Reduce Moisture Problems in Manufactured Homes

Everyday Activities Creates Moisture that Can Damage your Home

Cooking, bathing, heating, and even mopping all release excessive amounts of water into the air, which can lead to moisture problems in manufactured houses. As a result, everything we do harms our houses. Nice.

Fortunately, employing ventilation fans while engaging in these enjoyable everyday activities can be really beneficial; however, be sure to leave the fans on for a short period of time after you have finished your activity so that the fan can remove as much moisture from the air as possible.

Bigger is Not Always Better (when choosing the right air conditioner or furnace for your home)

A sincere apology is owed to my 9th grade algebra teacher, who I’ve had to use more times than I can count. Construction and blogging both utilize a lot of math. Who would have guessed?

A central air conditioner that is too large for your house will actually cost more to cool and can produce a lot of moisture in the air, both of which can damage your wonderful home. I’m not sure why this is, but it makes sense.

When the HUD says that “Equipment that is too large will turn on and off frequently, allowing humidity to build up indoors,” we’ll take their word for it.

Always Vent Your Propane and Kerosene Heaters (and not just because it can kill you)

Carbon monoxide can kill you, so you should do everything you can to keep it away from you at all times. Your fossil fuel heaters can produce a lot of moisture in the air, which is another reason you need to vent them.

According to HUD, “for every gallon of fuel consumed, nearly a gallon of water vapor is emitted into the atmosphere. Water vapor is a major source of damage in this area.”

Do Not Cover your Floor Registers or Neglect your Unused Rooms and Closets (they miss you)

Ducts in the floor or ceiling distribute your heating and air conditioning in manufactured homes. An unbalanced system can lead to cold areas and moisture buildup if these registers are closed or covered. This is dangerous.

When warm air cannot enter a location (whether it be a room or closet), the air will become “cold enough to considerably raise the relative humidity level in the environment, encouraging mold growth.”

Your Filters Need More Love

Perhaps your HVAC filters do more than just keep cat hair out of the system? According to HUD, these devices can “impede with an air conditioner’s ability to remove moisture from the air, and in some circumstances interfere with condensate drainage.”

More often than we think, filters need be cleaned or replaced. For optimal dust management and dehumidification, HUD suggests utilizing pleated filters.

More Sources of Moisture Problems in Manufactured Homes

This is just the beginning. It’s unfortunate that there are numerous sources of moisture that can cause damage to your house:

Poor Site Drainage

A healthy and long-lasting manufactured home relies heavily on proper site preparation and grading. As a homeowner, you need to be on the watch for puddles, leaks, and other concerns that could cause damage to your home after the installation.

Your home should not be surrounded by or have any standing water. Depending on the situation, you may need to hire a plumber to install elaborate drain lines, or you may only need to dig a small ditch. At the very least, we can hope for the best.

Crawlspaces and Skirting

A concrete slab, gravel, or polyethylene sheeting should completely cover the ground beneath your beautiful manufactured home to prevent moisture from the ground from becoming condensation that reaches your home.

In addition to your prefabricated home’s siding, your home’s skirting can be a cause of water damage. Math is going to get a lot more complicated. What if I told you that there are specific formulas to follow when it comes to constructing and installing your home’s skirting? Every 150 square feet of skirting requires 1 square foot of ventilation. To avoid dead air pockets, you must have vents within three feet of each corner.

Moisture and fire might result from a clogged dryer vent. There are a number of dangers if it is not properly maintained. Isn’t that interesting? Ensure that it is well ventilated outside of the crawl space.

Naturally, you’ll want to check to see if any of your plumbing pipes are dripping. There can be a huge problem even with a small leak.

Keep the Thermostat Set Above 75°F in Hot, Humid Climates

According to this HUD PDF’s authors, they’ve never spent any time in Florida in August. A temperature of 75 degrees Fahrenheit in the air conditioner does not always suffice.

“In the summer, keep the thermostat at or above 75 degrees Fahrenheit. Water can accumulate inside wall cavities if the thermostat is set too low in humid conditions. Okay, HUD, I’ll go with anything you say…….

In the South, where temperatures rarely get beyond 75 degrees Fahrenheit in August, it’s probably a good idea to brush up on your knowledge of moisture concerns in mobile homes if you’re anything like me.

How to Recognize Signs of Moisture Problems in your Manufactured Home

Moisture problems of any size can be remedied more quickly if found in the early stages.

Moisture concerns can be spotted by looking for the following:

  • musty odors that linger
  • blemishes on the walls and ceilings
  • floor, wall, or ceiling swell
  • the sight of frost on a window
  • your house is flooded from below

When it comes to manufactured home moisture issues, these suggestions are actually only the tip of the iceberg. There are a number of things you should look at if you notice water dripping from the ceiling or flowing down the walls or windows of your home. It’s a good thing it’s not more serious.
