How to Reduce RV Condensation and Prevent Mold

The formation of condensation can occur when camping in cold temperatures or in areas where there is a high level of humidity in the air. These water droplets will form on a variety of surfaces inside the RV, including the windows, walls, and counter-tops. It is important to keep RV condensation under control; otherwise your RV may be at risk of developing a mold problem. In addition to mold growth and its health issues, a buildup of condensation can also cause wood rot and corrosion. All of these can affect the overall look, performance, and value of your RV.

There are many tips we have learned from seasoned RVers when it comes to the formation of condensation. Here are some of the ones we have discovered work best:

Eliminate the RV Condensation Source

There are many different moisture sources inside your RV that you can control, which will help reduce the formation of RV condensation. For example, heating up food releases water vapors into the air and increases humidity levels. When cooking, make sure to cover all pots and pans to reduce water vapors escaping. Also, hang wet clothes outside to dry vs. inside. This way the water vapors from the fabric do not get caught inside your RV.

Increasing Inside Temperature

The formation of RV condensation increases at a lower temperature. If possible, run the thermostat a little warmer in your RV. This will help reduce the levels of condensation inside the unit. A programmable RV digital thermostat can assist with climate control.

Installing Window Insulation

Do-it-yourself window insulator kits are available at home improvement and RV supply stores. Once installed there will be a barrier between the window and the humid air, reducing the formation of condensation.

Using a Dehumidifier

Regularly using a dehumidifier inside your RV unit will help rapidly reduce the levels of humidity without increasing the temperature. There are small, compact dehumidifiers that are designed specifically for camping.

Ventilating the Unit

Properly ventilate your RV. This ensures water vapors in the bathroom after showering and in the kitchen when cooking get released outside. Some RV goers suggest cracking a window for a few minutes to help even out the moisture content in the air inside the unit.

Wiping Surfaces

When you see RV condensation starting to form on windows and counter-tops, take the time to wipe it away immediately.

Preventing Mold Growth

To prevent mold from growing inside your RV, it’s best to keep the humidity levels between 30 and 50 percent. Humidity meters, also known as a hygrometer, are available to purchase and install inside your RV to help keep track of moisture levels in the air. Some dehumidifiers are equipped with meters to help monitor humidity levels.

By using any of the above listed tips, or all of them combined together, you will be able to keep RV condensation formation down to a minimum and reduce your chances of having mold grow and causing damage to your unit. No condensation or mold will increase the amount of fun you have on the road.

    We have a 31′ C-Class and live in S. Florida where the humidity is always high. During our storage periods we keep 2 dehumidifiers running all the time (one in the rear and one forward) and keep the AC on 90 degrees. This increases our electric bill about $75-85 monthly but gives us peace of mind that we are mildew and mold free. And it always smells fresh inside.

    This is a topic I have never hear of in over 40 years of RVing. It reminds me of the old saying “An ounce of prevention, is worth a pound of cure.” Think I’ll at least get some desiccant dishes, like people use in boats!

      Hi Wayne. Thanks for visiting the RV Repair site and the opportunity
      to assist with your condensation problem. This is a
      common occurrence in units that are sealed up and running
      a roof AC and even sometimes with a furnace. The easiest
      way to reduce the moisture is open a vent slightly and let
      the moist air escape out the vent. You might also try a
      product called Damp-rid. I used it in a closet that was
      getting moisture and mold and it worked well.

      I unfortunately do no own a RV but I have a pop up and just opened it up to completely ensure that it was winterized as the temperature in SE NC where I live is finally getting well below freezing at night. When I opened it up I noticed that the canopy tope as well as the inside of the door that is attached to the top has started to mildew. Is there a way in which to prevent this is a popup camper? Damp-rid – does that work? Or do I need to keep it raised up and put a dehumidifier inside? Thanks for any help

        Hi Glenn. Thanks for visiting the RV Repair Club site. The first step in reducing the potential for mold and mildew is to make sure all materials are completely dry before storing them! Then I would suggest Damp Rid inside the unit.

          We camped with pop-up campers for years and never had a mildew problem, BUT we were diligent about not folding up the camper wet. If we had to move after a rain (or snow) we always got it up as soon as possible, and totally dry before putting it away for long term storage.

    I live in Wisconsin and the trailer gets stored for about 7 months. My ceiling vent is covered with a max air, so when open things will stay dry. Should I leave this open all winter to keep some air movement in the trailer?

      Hi, John. Thanks for visiting the RV Repair Club site. I know dozens of people that leave the vent open a couple of inches in the winter, dozens that leave them open 1/2 way, and dozens more that keep them shut so there isn’t any set answer to this question. We’ve always left ours shut because we did not have a Max Air cover but we did put a few Damp Rid containers inside and had to issues with moisture. Keep in mind the system has vents to the back of the cover to you can go down the road and not get rain or wind into the vent as well as reduce rain if camped. However, during storage, you could get a hard wind (especially in WI) from the back that could blow snow in through the vents into your open roof vent? Hope this helps.

      Thanks for visiting the RV Repair Club site. This has been a topic for argument since the first units became available in the late 1980’s! The earlier models that were single units vented inside the coach and it took for ever to dry cloths and the inside of the RV became a sauna! Today’s single units are vent outside so the moist air leave the rig and they do dry faster, however I find they still take longer than a conventional dryer and are much smaller. Their advantage is size, it only takes up half the storage space so you still get a shirt closet. The stackable seem to be more residential functioning, but take up more room.

        Our friends have the single unit. They hang everything after washing because the clothes get too wrinkled. We have separates and they function like home. You just need to dry out the door of the front load washer or you will get mold just like at home.

        I would not own the single unit. Losing the space is worth it so I can do other things while I do laundry and I know my machine.

      Hi Gary. Thanks for visiting the RV Repair Club site and the suggestion for video content. This has become a popular topic and has been added to the production schedule for future shoots. It’s a good topic as most people do not realize the issues with wood, tile, and laminate planking floors in an RV. As you drive down the road, the chassis will twist with road surface fluctuations as well as vibration. This will cause stress to the floor of the unit and ultimately the new flooring and buckle or even pop most bargain brand floors. Then add the temperature changes as the unit sits without climate control and the expansion and contraction creates another disaster! The best flooring is something that creates a “floating” floor when applied and created out of better base materials that won’t expand and contract as much as $0.49 cent per square foot bargain brands. Thanks again for the input.

    We have been RVing for about 10 years now. We were large vessel power boarded for 25 years prior to that. We used to live in Chicago but moved to South Florida 5 years ago. We put 2 five gallon buckets, with vented lids, filled about half full with regular charcoal. One in the front of the coach (36′ class A) and one in the back. I change the charcoal every 4 to 6 weeks. I also run an Evadry Petite dehumidifier on the galley counter and a small electric fan on the floor of the bedroom pointed forward town the hallway. The Evadry pulls about 2 pints of water per week here in South Florida and the charcoal will get mushy if you don’t change ut often enough. In all the years of boating and RVing I have never had sn issue but have had neighbors in the storage lots that have.

    We have a 29ft travel trailer and some how water got underneath our floor and rotted out the underlayment. Is this a fix we can do ourselves or would it be best to take somewhere to have it fixed? Who would fix something like this a RV dealer or Bodyshop?

    Reply
    • jean.wozniak

      Hi Cindi. Thanks for visiting the RV Repair Club site. The underlayment of your unit is more than likely 1/2” plywood. Most floors are made of a thin luaun material on the bottom, block foam or loose fill insulation filled in between either metal or wood framework, and 1/2” upper material and all sandwiched together with adhesive by either pinch roller or vacubond. It’s not an extremely technical repair, just labor intensive as you might have to remove lower cabinetry and furniture. I’d start by tearing back the carpeting or vinyl and seeing how extensive the damage is. You might be able to get by with just a sectional repair? Otherwise I would take it to an RV dealer or RV Service Center as they would be familiar with the construction and have access to the correct materials and adhesive.

      Thanks for visiting the RV Repair Club site. In my opinion, 2 pound block foam is the best as it provides insulation and also structural integrity to the panel. Make sure you use an adhesive that will not “melt” or eat away the foam. Test it on a scrap piece and let it sit for a couple days. (ZD: 2999)

    Hi. We bought a 1996 5th wheel for $4000 and the previous owner said he resealed it and it had no leaks. After a bad rain storm, the rv leaked and we found out it has rotten wood, mold and alot of water damage. We have only had it for almost 2 months and we never got it inspected. We don’t know much about rv’s either. We aren’t sure if we can get our money back at this point and the rv is not liveable in this condition. We need a place to stay big time and this was our only means. Can you tell me how much it might cost to replace the roof, floor and some walls? The water is everywhere it’s not good. I feel duped by these people. Would they not have seen the mold or water damage if they resealed it? Thanks!

      Thanks for visiting the RV Repair Club site. Without being able to inspect your rig to see how extensive the damage is and what needs to be replaced, it’s impossible to provide an estimate for repairs. However, just replacing a roof could exceed the cost you paid for the entire rig! I can’t vouch for the previous owner’s integrity, however if the damage is as extensive as you indicate I don’t see how they would not know it leaked. Plus you don’t reseal a rig if it’s not leaking in the first place? You might not have to replace all the wet and moldy areas as there are several products on the market that will help including bleach. I would suggest checking into your rights as a buyer to get my money back as it sounds like the repairs needed are far more than the rig is worth! (ZD: 3565)

    We have been working on renovating our 35″ dutchman RV for 3 years. We thought the dampness in the ceiling and rot in the walls was due to leaks so we have worked on addressing all the roof leaks, coated, replaced or added butyl tape etc. However the ceiling is still damp along one half, closest to the door. We doubted this could be a leak, because that section is running up hill a bit. Could it be ceiling condensation since the rv has been closed up with no ventilation for so long? I was in the process of replacing the ceiling when I found part of it was damp so I stopped. If it is condensation what can be done to address it. If it is a leak, I am not sure what else to do. Thanks.

      Hi, Andy. Thanks for visiting the RV Repair Club site and the opportunity to assist with your ceiling issue. I doubt it’s condensation as that might cause some staining of the ceiling material, but not as much damage as you have indicated. You could try cracking a vent slightly and putting in some DampRid but I think it’s probably a leak? Moisture leaks are what we call “gremlins” in the RV industry. They are deceiving as the point of entry may be a long way from the point of departure or damage! For example, moisture leaks in the front cap may travel all the way to the bedroom through the hollow frame rails of the upper sidewall and come out the bedroom. Resealing the entire bedroom area does not stop the leak just creates a lot of extra work and more frustration! I believe it’s well worth the money to find a repair center that uses Seal Tek a pressurizing method of finding leaks. This device sits inside the unit with a hose that is connected to a roof vent and draws air inside the RV pressurizing it. A technician sprays a soap and water solution outside and it’s the absolute best method for finding a leak! Yours could be the front cap, AC gasket not tight, roof vent, dozens of things and maybe a combination of things?

      Hi Gordon. Thank you for visiting the RV Repair Club site and the opportunity to assist with your AC leak issue. To provide more specific troubleshooting information we need to know the make, model, and year of your rig as some have traditional roof AC units, others have roof AC units that are ducted in the roof to vents, and others have basement mounted AC units with ductwork up to the roof to vents. If your rig is actually leaking water from the roof AC into the rig it could be you have not checked the torque of the tension mounting bolts. There are four bolts that need to be tightened periodically according to the type of AC unit you have. Check out the videos for the proper procedure.

      Hi Gordon. Thanks for visiting the RV Repair Club site and the opportunity to assist with your AC Humidity issue. To provide more specific troubleshooting information we need to know the make, model, and year of your rig and the type of AC unit would be beneficial as well. What typically happens in a two AC system is the front AC is larger and has a better cold air return design which circulates the air and the evaporator dryer removes the moisture. The bedroom AC is often times just a direct vent like a window AC in a house and dumps moist air in. If your system is ducted, I suggest running the front AC at night and shutting all the vents in the front and let the cool, conditioned air flow to the bedroom which is quieter as well.

    We are brand new to RVing. My 5th wheel has 3 slides. The bedroom slide has 3 rollers, the kitchen slide has 4 rollers, but the largest living room slide only has 2 rollers and after only a few uses the center of this large slide is damaging the floor. The underside luaun material is being peeled back exposing the block insulation. How many rollers should this slide have and is this something I can fix myself?

      Hi, Ken. Thank you for visiting the RV Repair Club site and the opportunity to assist with your slide room issue. To provide more specific information on the number of rollers the room should have, we need to know the make, model, and year of your RV. There are three major manufacturers of the larger mechanism, Lippert Components Inc, Power Gear which is now owned by LCI, and HWH. If the floor is getting torn up, it’s more likely the pad the room slides on is the problem? Most rooms have rollers at the sidewall and some type of plastic strip or pad out on the end of the room that slides in and out. Run your room 1/2 way in/out, get a good light and place it on the floor, put a piece of wood on the floor and use a pry bar to lift the room and look underneath. I believe you’ll see a very worn runner?

          Sorry for the delay in my response, however I have had no luck getting any information from Open Range, aka Highland Ridge RV as of March 2014, aka Jayco who was recently purchased by Thor Industries! I did stop by the Open Range display at the RVIA National Trade Show in Louisville KY last week to look at what a typical 29’ unit had for slide mechanism and did not see anything in the center underneath from the inside. You can’t really see much from the outside as the weatherstrip flap covers up most of it. And of course there were only “sales representatives” there and nobody with any technical or engineering knowledge. I did find an Open Range owner’s forum that might be of assistance. You could post your question here at: http://www.openrangeowners.com In the mean time, what is actually happening as you bring the slide in and out? If you believe there is something missing in the middle, is it scraping the floor or some other type of damage?

      Hi, Mary. The first thing you need to do is identify if the white substance is actually white mold or efflorescence which forms on more hard surfaces. Spray water on the substance, if it disappears, it’s not white mold. There are several products on the market to treat and remove mold, my favorite is simple bleach. Take 1/4 cup bleach in 1 gallon of water and treat the area with the mold and then put DampRid in your rig to reduce condensation that helps cultivate mold.

      You will need to start by pulling off the ceiling material whether it’s fabric, padded vinyl, or paneling. Fabric and padded vinyl will also have a luaun panel underneath. Look to see what type of damage and rot there is in the wood and insulation. Start with just the area the is blistered so if it’s not to extensive, you can replace the rotten material and possibly piece a new panel and material in that area. You will want to replace the panel or material across the entire coach rather than just a square patch which would look bad. We have done this several times by loosening the overhead cabinets to tuck in underneath, replaced a section about 3’ wide side to side, and attached a molding to the seams. In the case of paneling, you can just glue a seam tape, with the other material we used wood strips stained to match the cabinets and added more to the ceiling at 3’ intervals to make it look decorative and not a single section replaced. Turned out nice.

      It all depends on the condition of the existing sealant.  If it’s brittle with cracks and separation in several areas, I would use a heat gun and remove it.  Also, if you have a leak and can not seem to find it, remove it and start over.  This is a large project, so most owners just want to do a quick “over-seal” which will be a problem if you have some of the major issues.  Clean the sealant thoroughly with Dawn (Blue) dishsoap or denatured alcohol if it’s really bad.  Then inspect the sealant to determine the level of deterioration.  If it is minor, make sure you use a sealant that is compatible with what is on
      your rig!  Silicone is not good for everything and there are dozens of types of silicone, just walk through a home improvement store and see the choices!  Find out what type of roof material you have and that should tell you the correct sealant.  Check with Dicor and even EternaBond for the best sealant for your application.

      Hope this helps!

    We are camping in the mountains for the winter. Experiencing condensation on the interior of the front cap where the head of the bed is located. How can I stop this?

    Got home from a trip and one of the scissor stabilizers in the front fell off…screws and all. The belly in the front needs to replaced so I can remount the stabilizer. Need some advice on how to proceed.

    We have lived in our rv for one year and seven months. We bought the rv new. I noted that there was condensation early on and got a small dehumidifier to help. We also vent when done with showers, use the stove fan, and open everything up as much as weather permits. This weekend I became tired of the constant wetness behind our “couch”. The walls are always wet despite efforts to keep them dry. I decided that because I couldn’t get behind the couch that I would remove it, clean behind it and get another seating arrangement that would allow air behind and around it. After removal, I took pictures. I pulled up the carpeting and there is black mold all over the subflooring plywood. I am sure it is inside the walls as well. I am unhappy with this situation. My spouse has COPD, which makes the mold a dangerous health issue for him. I do not know what to do about this event. I am also sure that there is mold under the table area. Why are these rv’s designed so that people cannot keep air circulating to prevent mold? Warranty was only for one year; Now what?

    I use “DampTraps” available for a buck or two at most dollar stores. They are very useful in the outside storage bins.

    We store our Coachman trailer for the winter inside a new indoor storage center for about 6 months each year
    It is 100% dry storage, non heated.
    Every time we get our camper out there is mold all over the cabinets, some on the windows some on the stove top some everywhere. It has done this since it was brand new four years ago.
    It has no water in it, it has no water anywhere near it.
    No one can seem to help with this, we do not have it plugged in, no heat is on, where does this come from???

    I keep finding a layer of water on my rear kitchen counter top and there are no leaks from windows or roof. Very carefully inspected. But at this last rain I opened the 2 windows there a little but to let air out and turned on a fan and placed a damprid unit right ther on the countertop and a towel underneath. And I still end up with a wet towel. And when I say I have inspected this thing I mean thoroughly and there are no leaks from windows, or roof in overhead cabinets. What do you think?

    We had 6 tubs of Damp Rid inside our closed and covered RV out in the Jacksonville Florida yard …. a month later, all 6 had water floating on top, and the white beads have become a solid mass. I’ ve poured off the inch of water and put the tubs back in their spots but it seems like they should have lasted for months, and absorbed any moisture that may have gotten inside. There are no bad odors, or any signs of moisture/rain leakage. The camper is brand new and sitting in storage until our upcoming periods of use. What can we do to insure that mold will not become a problem over the upcoming summer months when we’re not here to keep an eye on it, or to change chemicals ???

    Hi, I’m going to repair some rot in the walls of my unit requiring removal of some cabinets. I’m not able to see how they are secured to the wall. Any suggestions on removal techniques? Also, is there a source for wire diagrams for this unit? The squirrels got in and chewed through the running lights wiring in the floor and I would like to shorten the journey to locating the wire pathway for replacement. Thank you.

    We recently had left our kitchen faucet on causing most of the floor to get wet 2 days ago (Memorial Day). We cleaned up the water on the floor within about 4-6 hours of it happening. Now I’m doing my best to get as much moisture out as possible. The problem is its been raining off & on. And we live 20 min away from our camper. I did stsy in our camper on Mon night & kept the windows & all the doors open. On Tues I used a BIG fan in our camper thru the day, but had to leave & close it up tight for the night. I haven’t been back to our camper since late last night. Though I used a generator & our fan should have been running from Tues (6:30 pm- 6:30ish am w/ 3/4 of a tank of gas. Any suggestions on whether to keeping a window cracked or keeping it sealed? We’re supposed to get a thunderstorm tomorrow (Thurs). I’ll be able to have a full size dehumidifier in it by Friday morning.

    I flushed out my black water tank, some of the black water went on to the floor and in to the heater vent, now when I turn on the heater I get a real bad Oder coming from the vent. I have tried every thing to get rid of it. Wood it hurt to pour diluted bleach water or vinegar water down the vent to kill any thing that may be left in there, bad smell
