Although it doesn’t have a tremendous range, it was incredibly accurate and consistent. Truth be told, we used this model as the baseline for accuracy in our test. The moisture meter should include the features a DIYer wants but also have a reputation for durability and long life. Consider options that have a rubberized casing, a heavy-duty design, or shock resistance built in. These moisture meters will survive a few falls without damage and make a great investment because they’ll need to be replaced less frequently.
Many sources inside the home increase the relative humidity of the home. Condensation can cause staining, deformed or decaying wood, paint damage, and powdery concrete. The owner or principal of each business in HomeAdvisor's network must pass a background check. Unfortunately, we cannot perform a background check on every employee of a business—the background checks are performed only on the owner or principal. As always, we recommend that you conduct your own research on the businesses you hire, including making inquiries directly with the businesses regarding their employee background check policies. The HomeAdvisor Community Rating is an overall rating based on verified reviews and feedback from our community of homeowners that have been connected with service professionals.

An inspector can use a moisture meter to locate moisture that would not otherwise be apparent. The pin moisture meter settings can switch between four different wood groups containing 50 wood species for precision measurement. The large LCD screen is easy to read, and the body of the device comes in sturdy ABS plastic for superior durability. This moisture meter won’t work with concrete, gypsum, drywall, or other nonwood building materials, but DIYers with wood-based projects have an affordable specialty pick. You can use this moisture meter for plaster walls, drywall, carpeting, flooring, brick, grout, soil, paper, or powders, and it shows readings on two bright displays. Pinless moisture meters make it easy to test for moisture in walls without so much as a scratch.
Pin moisture meters get their name from the two metal prongs, or pins, that emerge from the top of the meter like antennae. Using a pin moisture meter requires aligning the pins with a spot on the material, and then pushing them so they penetrate the material. If you own inexpensive moisture meters, you may think it isn’t worth carrying equipment coverage for them. However, for any items worth less than $1,000, our equipment coverage allows you to cover the property as miscellaneous tools. What’s more, through InspectorPro with the ASHI Advantage, ASHI members can get up to $20,000 in equipment coverage for just $200 per year.
Common Outdoor Sources of Moisture
You can check the moisture levels on and within walls using a pinless digital moisture meter . They don’t require you to cut holes in the walls – they are completely non-destructive tools for measuring moisture. Certain accessories for pin-type meters do leave holes that’ll require repairs. Attachments like hammer probes and deep wall probes are designed to take moisture readings far beyond surface level.
If you do collect a high moisture reading somewhere on the property, don’t stop there. Take multiple measurements of the same area to ensure that it is, in fact, damp. Some sources of moisture originate outside and require regular maintenance and/or repairs to stop water from penetrating the building envelope. If you have noticed moisture on your interior walls, then the level of moisture in your home has probably surpassed the recommended levels. Dry rot happens when water vapor penetrates into wood causing decay.

DIYers and pros looking for a moisture meter place accuracy as one of the most important factors in deciding which one to buy. A unit lacking in accuracy is essentially useless for measuring moisture. Professional-level meters usually cost around $60, and a product warranty should be considered with your purchase to protect your investment. If the meter’s case is cracked or broken, the tool should be replaced. Pins and electronics can be safely cleaned with isopropyl alcohol and a soft rag.
Mold in a household is unfortunately very common, when ignored or left alone it can lead to migranes, nausea, respiratory issues, and more. Moisture meters, like most electronic devices, can pack plenty of additional features to make the task easier. One of these features is a temperature display that can track a hot or cold water leak. Finding excess moisture in a structure should be reported, with recommendations for the appropriate contractor to correct the situation, if warranted.
The #1 Place to Take Water Damage Moisture Readings After a Flood
Lastly, your clients may not have an accurate understanding of what moisture and dampness might mean. Explain how excess moisture can affect the home, but don’t make conclusions without substantial evidence. However, since high moisture can promote mold growth, high readings may indicate the potential for mold. In such cases, it’s appropriate to recommend further evaluation through mold sampling. Fill the test holes if visual and mechanical readings indicate normal moisture levels inside your wall. Outside, squirt colored or clear silicone caulk into the hole to fill it and render it waterproof.
For example, if the temperature in the room is around 80 degrees Fahrenheit, and the RH is 50%, then a “safe” level of moisture in the wall would be about 9.1% MC. What constitutes a “safe” level of moisture in a wall will change depending on what the wall is made of. However, older buildings may use other interior wall surfaces, such as wooden paneling or plaster.
Typically, a moisture meter is calibrated for use with wood and has a scale between 5 percent and 40 percent . Measuring nonwood materials like concrete uses a relative scale from 0 to 100 . Moisture meters for use with gypsum or drywall offer a third scale that ranges from 0.2 percent to 50 percent . Before deciding on a moisture meter, determine the accuracy levels you need and the materials you will want to check. In summary, moisture meters are capable of detecting moisture levels in most building materials. They are useful tools to have during home inspections because they can calculate the properties of inaccessible locations without causing them any damage.
As a home inspector, you can use the same principle with your moisture meter. Take multiple measurements—including measurements of dry materials. What if adding exterior insulation just isn’t an option for your newer home? Then run exhaust fans frequently, while also opening a window at the opposite end of the house. By allowing air to flow through your home, the colder, drier air from outside will pick up moisture and help it flow out of the home. By properly sealing any chases that enter your home through the walls or basement, you can significantly reduce the risk of moisture.
Finally, we went through all the settings, modes, and extra features . At this point, we had a solid grasp on which models were worth the money and which we needed to discard from the test. Readings typically take five to 10 seconds and should be done at least twice to ensure accuracy. If an area is found to have moisture, the edges of the problem area should be located, if possible. Join over 30,000 home inspectors who receive risk management tips twice a month from the InspectorPro newsletter. These sources can often be mitigated by using exhaust fans that are vented to the outside.
Inserting the pins into the material sends a current down one pin to flow into the second. The meter then measures the resistance the current met traveling through the material between the pins to generate a moisture reading. This multifunctional moisture meter helps DIYers test for moisture using pinless, flat sensors without damaging the material. This method of measurement is considered invasive because it requires puncturing the material to obtain a result. However, pin moisture meters are the only type that can help identify the exact location of moisture.
Home Inspections: Testing for Moisture in Walls Damage-Free
Wood can typically hold up to 25% without showing signs of deterioration. Moisture meters work well with concrete, wood, tile, vinyl, gypsum/drywall, plaster, and many other building materials. Furthermore, knowing what your moisture meter can do and how to interpret its findings can prevent claims. Hurtado says inspectors who are new to using a particular meter or meters generally can make mistakes if they aren’t careful. For example, they could attribute high levels of moisture to a concrete wall with a normal level of moisture for such a porous building material. Or an inspector may hit a metal corner bead at the corner of a window and say it’s a leak.
