Here's a Tip for Validating Moisture Within Walls

[@kimbecker1225]

Wish you made a couple dozen videos where you bring us along on inspections. That was really helpful.

[@IAQJosh]

Working on it! I have some first person POV videos that I have planned coming up.

[@TimKaseyMythHealer]

Great time to use a moisture meter is after a heavy rain. Sometimes the ceiling only gets a few drops per 5 minute period, and its not enough to make any visible damage. Check ceiling just below roof vent areas! Also, I just learned that sheetrock corners where the install corner bead (metal strips installed on wall edges to make a strait edge) will give false moisture readings. If you know that a drip has been occurring for 24 hours, get a space heater on a speaker stand, and heat up the ceiling or wall surface to around 120 degrees. Attic side, pull back insulation to expose ceiling sheet rock, and place a fan up in attic to blow across. It will take about 5 days to dry out the back side of sheet rock with a space heater. Oh, yeah, don't forget to repair the roof leak.

[@IAQJosh]

Yessir! Metal corner beads are one element that I need always remind people of - especially those new to moisture meter use. As to your mention of utilizing heat to dry building materials, this certainly works well. 120 degrees is a bit up there, for my liking, but I’m sure you’ll achieving some rapid drying!

[@sparksmcgee6641]

Only 24 hours of material being wet it has mold and should be replaced.

Hi. Do you have a specific products to recommend for testing moisture.? Thank you

[@essentialhandyman]

Interesting to see how you approach damp diagnosis in USA. As a building surveyor in cold and wet England, we get lots of damp and mould issues for me to survey. I personally always also check the exterior of the building for leaks, cracks, drainage issues etc., before recommending you need to remove the drywall (we call it plasterboard). Is it common practice over there to not check the exterior of a building?

[@IAQJosh]

While I cannot speak for others, I can share that I will always check the exterior of a property. Especially as you said, I constantly find cracks, inadequately sealed openings for plumbing and electrical, etc. Paying close attention to the height of the landscaping, in reference to the height of the slab, is especially important in some areas here.

[@lt8710]

I'm not a professional, but checking exterior without removing siding for example would be hard. When it comes to windows, there are many ways to mess up the install. There should be cauking and duck/insulation tape used. Also, depends how the channels were installed around the window. Remember in US. Can be moved in a day, and you would not be able to tell that they were. Quick process.

[@sitori2509]

In my state 99% of inspectors especially "mold inspectors" are lazy and incompetent. They don't inspect the outside and barely inside. I just had an IICRC certified water intrusion inspector and certified in "microbial application" - some nonsense like that. He literally waived his moisture meter over the wall. He never placed the pad on the wall, thinking I as a woman wouldn't know better. It wasn't a Flir camera. He also kept saying repeatedly "mold is ubiquitous" - like he was so proud of himself for learning a "big" word. smh I enjoyed letting him know after he was done with his nonstop BS mansplaining that I am a Certified Mold Inspector. I took a 24 course and got certified after educating myself first enough to realize how ignorant and incompetent the mold inspectors Iwas hiring were. The companies/ inspectors that seem to actually know what they are doing charge insanely high fees. There truly is a crisis in the US when it comes to mold and moisture problems in homes and the lack of true understanding of the danger and professionals qualified to inspect and address it. Licensing and continued education should be mandatory.

[@heatherrhodge2588]

​@sitori2509 doesn't surprise me. Even doctors are too incompetent to actually help patients. There are loads of diff "professionals " these days who know much less than your common hobbyist!! It drives me up the freakn wall!! I've wanted to have a mold inspector come check my house, but I don't trust any of them to do a decent job! I've had HVAC professionals come here the past 3 or 4yrs when my AC refused to cool. It's still not fixed!! When the weather gets close to 90° outside, the AC stops cooling. It's been doing the same thing all these yrs & despite paying them 100s$ every visit, they never fix it.

My 14 yr old custom house had water coming through in master bathroom roof. I have a pass through fireplace in master bedrm/master bath. Last January. I had roofing company come and see - they said I needed ‘debris’ cleaned and some flashings replaced. And some tiles near both chimneys were cut. Cost was $3,200. They cleaned all the debris from the valleys and cut some of the tiles back away from chimneys.This was Jan 2023. Here is what they wrote on my invoice: “ An inspection of the roof was undergone to determine what maintenance was required.
We found the tiles behind the two chimneys to be too close to the chimneys allowing debris to build-up which caused the water to overflow. This was repaired by cutting the tiles by 6" to allow the water to properly flow.
Secondly, we found the valley metal ends were on top of the tile and this causes the water to spill over the valley and run allow the underlayment, which can cause the underlayment to prematurely deteriorate. This issue was repaired by cutting back the valley metal ends and installing a lead extension on the five valleys.
Lastly, we found the valleys and cricket to have debris. We underwent a clean-up, which will allow the water to properly flow…” We had a lot of rain in Feb and March and even some in August. All seemed, but to my shock, last week, I noticed a stain on ceiling of a bedroom not anywhere near where the January leak was. But this bedroom backs up to living room in area where there is another fireplace/chimney. I don't know when this happened. I seldom go in that bedroom and I seldom look at my ceilings. But water must have gotten in somehow. . I called the roofing company and left a message. Waiting for them to call me back. I got a ladder and went up to feel the stain and there is no wetness or puffiness on the ceiling. November is a month we often get rain. Of course if we get rain before the roofer calls me back I will be sure at watch the ceiling where that stain is. Is it possible that there was an unnoticed issue in this room but no problem NOW since the roofer worked on BOTH chimneys? Should I get a moisture meter?

[@IAQJosh]

A moisture meter is certainly something that most people should own. It also fits nicely inside of a kitchen drawer. 😉 When stains are found, it can be helpful to utilize a moisture meter to determine if these spots are active water intrusion or prior damage - especially when it’s a stain that one doesn’t recall seeing within their home.

[@1234tellmewhatyourlookingfor]

I use a Flir camera. Protimiders will reflect off metal and give you a false positive. The Flir can read electrical outlets and main electrical panels. You check for hot spots.

[@IAQJosh]

I love using my Flir camera to quickly scan building materials for thermal anomalies. Definitely cuts down on the “guess and check” game, when it comes to searching for moisture across large areas. Also great for locating overheating electrical components - as you mentioned. As you may know, all moisture meters will detect a false positive when they come in contact with meter. It’s not just Protimeter meters. Every tool has its limitations.

[@TeeTeeBanks]

Thanks for the video. Can moisture readers read btw plaster walls??

[@IAQJosh]

In general, moisture meters can read moisture content within many plaster walls. Some plaster walls, which are primarily composed of wire and lathe, may provide a false positive to non-penetrating/ pinless moisture meters. These false readings may indicate elevated moisture, when in fact you’re merely reading the metal wire within the wall. I find that it’s best to have a penetrating and non-penetrating moisture meter when evaluating plaster walls. This will allow you to collect varying readings from both meters across multiple areas, ultimately to determine if a wall has water damage.

[@AiBilly]

I don`t have any of those gloves, will i still get the proper reading ? ?

[@liverpix]

Do you know what was the cause of the wet wall and how it was remedied ? Thanks.

[@karabathesorceress6923]

So what if you are aware of water damage is there guaranteed mold? My roof has leaked throughout a few widely spaced storms and in those 3 or 4 occasions I had water leaking into the house along a couple parts of the walls where there are exposed beams. Each time it dried the landlord came and recaulked and puttied the inside leak stains. After the most recent leak they tarped the roof and I haven’t seen any sign of water coming in since. However this time there was the most amount of water for a longer period of time and there is still a discolored stain where the biggest leak was. I bought a moisture meter to test these areas and most of the readings along these two walls were around 8-10% and in two small areas the highest was about 17%. Does this indicate a mold problem?

[@duane6950]

Thanks for sharing. As for measuring drywall - those pins actually puncture the drywall yes? in other words, not suitable for taking around on a house viewing, better to take the non invasive one and skip the pin readings

[@IAQJosh]

The best process that I’ve found is using a thermal camera as the initial screening - looking for anomalies that may be related to elevated moisture. I’ll then use a non-penetrating moisture meter to confirm if the anomalies are indeed elevated moisture concentrations. In addition, I’ll use this meter throughout the area below windows, as thermal cameras do not always highlight problems. Lastly, I’ll use a penetrating (pin) meter on the drywall scale to confirm that I’m not picking up any false readings with the non-penetrating meter. Following this process, I’ve been able to greatly limit the amount of damage left behind on walls. Arguably, you can use a non-penetrating meter like the Tramex on different depth settings to ascertain more reliable information, without having to place pins in the walls - assuming pin usage is a no-go in your situation. While not a guarantee, using different depth settings will allow you limit the potential for false readings by limiting the influence of objects behind the drywall - such as metal strike plates, etc.

[@peterloichtl4512]

Only a snowflake would worry about 2 needlepricks in the wall, the are so small the only way u would know where the are there is if someone that made them pointed them out to u. If you are really worried about a couple of needlepricks in your walls you have bigger problems then wet sheetrock.

[@vaxmax8620]

Very helpful video! My renovated shower smells like mold. Room is more ventilated than before as an exhaust fan was added. Is there a way I can measure moisture in the tiled walls and tiled shower pan floor?

[@IAQJosh]

Thank you for the feedback! As far as measuring moisture concentrations within tiled walls, you’d ideally want to use a professional meter, such as a Tramex Moisture Encounter. If you use another type of non-penetrating moisture meter (meaning one without pins), you’ll want to collect a number of reference readings on tiled walls that you presume to be dry and free from water damage. Then you would collect readings from areas of concern and compare. With the above said, you will typically find greater moisture concentrations within tiled walls toward the base of the walls. This can be for a number of reasons, but don’t let consistently high readings through the base of the walls lead you to believe there’s water damage. If the numbers are all high and around the same levels, you’re likely dealing with a false-positive. Lastly, a tile shower floor atop a shower pan can be extremely difficult to measure for moisture concentrations. My best hit of advice would be to rely more on concentrations that you collect from the surrounding walls and other immediate areas adjoining to the shower. Lots of potential for false-positives when readings tiled floors. If you have a meter like the Tramex, you can use the shallow depth setting, which is often your best bet in instances like this.

Great video. Will a moisture meter also work on vinyl plank flooring? I have vinyl plank over a slab and my tenant thinks its getting wet between the slab and the flooring.

[@IAQJosh]

Excellent question! Yes, a non-invasive moisture meter will work for detecting areas of greater moisture concentrations beneath the vinyl planks - when they are glued directly to a slab. Given the varying results when collecting moisture readings from concrete, it’s best to collect a number of dry area readings (comparative) and then a number of suspected wet area readings and then separately average them out. This will provide you with a better idea of the suspected wet area as a whole.

[@Shenanigans000]

I just noticed the same issue right near my outlet (wall was wet and dripping) but the moisture detector only picked up one specific small spot of moisture right near the outlet..... Everything else on the wall and ceiling is completely dry, Does it still mean the whole wall has to come out or maybe just a small hole cut right where the moisture is?

[@IAQJosh]

Great question! I personally performed an assessment sometime last year, where I was asked to evaluate perimeter walls within a few different condos - with the primary concern being the presence of mold growth within these walls. In the past, a contractor cut out only the wet areas, which essentially involved numerous random cutouts on some of these walls. Flash forward to me coming in and setting up a sampling pump alongside a few outlet covers as part of my assessment. I found there to be some pretty large quantities of mold spores present. Moral of the story - it’s often better to simply remove a larger portion of wallboard during remediation. This will ensure that you remove both the moisture-impacted materials, as well as the presence of mold growth. You may want to start with removing the drywall from the floor up to the base of the window sill. If there’s no evidence of moisture or mold, that should be sufficient.

Hello Josh. What's normal moisture for plastered walls? On my walls it looks like the paint it's starting to look like it's not spread evenly and it wasn't like that before. And what type of company would I call to test the walls?

[@IAQJosh]

Hey there! Unfortunately, there is no standard number or range when it comes to normal moisture content within your wallboard. Also, it depends on the type of meter you are using, as pin vs. pinless meters will typically yield different numbers. On a scale of 0-100 for the plaster scale, most commonly I find plaster to be in the 0-10 range. Very seldom does dry plasterboard show any noteworthy level of moisture concentration. With that said, the moisture levels within the indoor air quality will certainly influence the moisture content within building materials such as plaster. My best advice would be to collect moisture meter readings from similar walls in other areas of your home where you don’t believe there to be a problem. If you’re seeing these paint spread marks on a perimeter wall, check perimeter walls in other rooms. If this damage is on an interior wall, check interior walls in other rooms. Simply make sure you are comparing similar walls. Lastly, a company that can check moisture readings for you would be most professional assessment and remediation companies. If you want to put your worries to bed, or at least warrant the concerns, you may want to consider hiring one of these types of companies to perform a moisture survey. This will highlight areas of concern with respect to elevated moisture concentrations within your property.

Hi Uli. Sorry to hear about your situation, but there is some good news! More often than not, finding “elevated” moisture toward the base of a of a tile wall or floor is a false positive. Well, by false positive, I simply mean that it’s likely not actually wet (beyond normal moisture levels). Assuming you’re talking about the base of a wall, or even wood baseboard, there can be a number of reasons for findings abnormal moisture levels here as well. As I don’t have enough information to fully understand your situation, I would recommend shooting me an email and possibly attaching some photos of what you’re dealing with.

[@wexworld838]

What do you consider to be "normal moisture levels" in a wall. Thanks!

[@IAQJosh]

Well, given that each property will vary with its airborne humidity levels, it depends. In drier environments, I’ve seen moisture concentration levels (in drywall) lower than 7. In wetter environments, I’ve see levels (in drywall) as high as 40. Now, if you’re using Delmhorst’s drywall scale on their pin style meters, you should typically see moisture concentration levels above 0.3%. Their scale have proven to be extremely accurate and useful for verifying moisture content with drywall. Keep in mind that all of the above pertains solely to drywall. If you have plaster walls, the levels may very dramatically. One of the best things someone can do is to collect a few moisture readings from known dry areas (areas away from any plumbing, windows, doors, etc.). As long as there are no signs of water damage, you should be able to see some pretty consistent readings - which can be averaged out to find your “dry standard”. This same principle would need to be applied to an interior wall, if you were comparing walls separating rooms, as opposed to perimeter walls.

What is the acceptable moisture level in aà house

[@IAQJosh]

Hey there! The acceptable moisture levels within a home will vary, depending on numerous factors. Climate is one factor and indoor ambient conditions are another factor. If you're using a moisture meter with a drywall scale, similar to that of Delmhorst's scale, 0.3-0.5 tend to be average moisture concentration levels within your average home in South Florida. Using a relative (0-100) scale, you'll see varying results, which will make it more difficult to identify what's normal. My best bit of advice would be to collect background moisture points within your home, in similar construction materials. For example, if you're trying to figure out if a window is leaking, collect moisture concentration readings around windows that have an overhang. Then compare these readings to those that you collect from a suspected leaking window. The idea here is that the likelihood of a window with an overhand leaking, as compared to one without is much lower. Granted, other factors may come into play (e.g. sprinklers). Hope the above info helps!

Hi Demetrius! I’m so sorry to hear of that news. Depending on what you mean when you say the house is destroyed, you may want to consider speaking with a mechanical contractor - like a quality HVAC/ ventilation company. There are instances in which you can dilute or fight off indoor environmental hazards by creating a positive pressure environment. By bringing in outdoor, filtered and conditioned air, often times you can dilute or remove contaminates by pushing out outward on your building envelope. In layman’s terms, the outside air your are bringing in mechanically can push everything into the wall and ceiling cavities and keep those contaminates from impacting your indoor air quality. Just a thought, if that sounds like it would help.

And on the wall he should have used a pin type moisture meeter because the are more accurate. Its redicules to assert the tiny unnoticable pinholes a pin moisture meter leaves, warrant not using it. If i cant leave tiny pinholes in a wall that no one else will notice, i simply wont do the job. If presently everything is dry the suspected leak outside the home is fixed before the next rain and there is no mold now there never will be mold because mold wont grow on dry surfaces. So no reason to tear out the wall, change the outlet, fix the leak outside, spakle the small spot where your finget found a bubble. Done deal.

In most cases, we would just take it close to the adjacent walls, making the build-back Contractors life easier. When I say “entire wall”, this is what I’m referring to. Needless to say that there is no reason to remove any of the drywall above the window at this point.
