We’ve compiled a list of the most frequently asked questions related to moisture testing. Click on any of the questions at the top to jump to the answer below.
No. Moisture testing involves drilling 3/16” holes and then patching the holes with caulk of a matching color. We bring along over 30 shades of caulk in order to find a good match. Once we’re done, the moisture testing holes are typically only visible to someone with a trained eye, or someone who is looking for the holes up close.
No. After testing thousands of stucco homes for over 20 years, we have never had a single case where water damage occurred as a result of moisture probe testing. Probe testing is the most reliable and least intrusive method available for testing stucco homes.
Moisture testing will puncture the moisture barrier, however, by injecting caulking all the way inside the hole, it will also be able to seal the penetration.
It is difficult to match the color of stucco, and to have stucco mixed and color-matched on site would be cost prohibitive. Caulk is a flexible material that can be injected deep in the openings, making it a much better solution.
Sure, but you’ll be bored. This isn’t like a home inspection where it’s a great learning experience; moisture testing involves setting up ladders, drilling holes, taking moisture readings, and then filling the holes. It gets pretty repetitive. If you plan to attend, bring a book along.
The home I’m buying has real stucco, not the synthetic stuff that has had all of the problems I’ve heard about… so I should be fine, right?
Quite the contrary. The “real” stucco is what we’ve had so many problems with here in Minnesota. Reuben blogged about this back in 2012: Problems with stucco houses in Minnesota.
Please call our main office number for the most current availability.
Our prices are based on the size of the home. For whole-house testing, our price starts at $545 for homes up to 3000 total square feet. For a single wall, the price is $395.
A warranty can be purchased through MoistureWarranty.com. Our moisture reports are accepted by this service as qualified moisture inspections.
Most reports are sent out within 48 hours of the moisture test.
No, we cannot perform exterior moisture testing in the rain. Our equipment will get wet, making an accurate moisture report impossible.
Yes, moisture testing can be done right after a recent rainfall. We’re probe testing the interior wall sheathing, which should always be dry.
What if it hasn’t rained outside for a month? Won’t the wall be dry, making a moisture test impossible or useless?
If it’s a home with stucco or stone siding, we can still provide accurate results. Stucco homes takes months to dry out, making it possible to perform moisture testing throughout the year.
No, we can always perform moisture testing from inside the house. For exterior moisture testing, it starts to become difficult once temperature drops below freezing. A sunny, calm day in the teens is probably fine, but once it gets colder than that we can’t do exterior testing.
Yes. Home inspectors and moisture testing techs will not get in each others way. If you’re using us for the home inspection, you can actually do this all with one call.
