The Best Moisture Meters
Whether you're fixing drywall or building a shed, you'll need a moisture meter. That's because the moisture levels can affect things like mold and mildew growth, how well the paint sets, and even how your wood might warp. They can save you hundreds of dollars (or even thousands), and they can prevent the need for mold remediation down the line, which can be very costly. There are different types of moisture meters, and it can be hard to choose which one is best for your job. That's why we're here to help with this round-up of our absolute favorites.

Frequently Asked Questions
Should I choose a meter with or without pins?
Moisture meters are either pinless or use pins to detect moisture content. Neither is better and they both have their place. For example, the pinless meters aren’t always as accurate as the ones with pins, but you can slide them around the wall to find the problem spot, which you can’t do with pins. On the other hand, once you know where the moisture is, the pin meter will give you a more accurate reading.
Why would I need a moisture meter if I’m not a professional?
Whether you rent or own your own home, a moisture meter is a good tool to have in your toolbox. You never know when a leak or other problem can happen. If your walls seem to be bubbling or you’re starting to notice some mold in your home somewhere, a moisture meter can give you a clear idea of where the water is coming from so you can have it fixed as soon as possible.
