I find that internachi education is by far superior to all of the other online education platforms that are available. I study and educate myself on an ongoing basis to improve my ability to educate my clients and their realtors about the importance of a through and in-depth inspection. The ability to perform a detailed inspection with a detailed inspection report should be at the top of all inspectors list of credentials.
The continuous radon monitor CRM is a very effective and accurate tool used to measure radon for home inspectors. This model by Sun Nuclear is a typical CRM. It provides the ability to perform 48 hour radon measurements which is necessary for home inspections done for real estate transactions.
Toilet inspections are very important and also very easy. Some key areas to look at with toilets are leaking on and around the floor and toilets that are loose. The toilet can be loose due to the bolts on the base needing to be tightened. It also can be caused by a poor wax ring seal. Toilet inspections are a great area to use a thermal imaging camera and moisture meter to ensure that there are no moisture issues.
Radon is a colorless, odorless radioactive gas thats produced by decaying uranium. Its present in nearly all soils, and very low levels of radon are found in the air we breathe every day.The problem occurs when radon gas enters your home and gets trapped. Long-term exposure to high levels of radon can cause lung cancer.
The most common radon mitigation technique is called either soil depressurization, or active subslab depressurization (ASD), or subslab suction (SSD). This is by far the most common type of radon reduction system installed today. Generally, a hole is drilled through the basement slab, a cavity is excavated beneath the slab, and 3" or 4" diameter PVC pipe is run up from the slab, out through the basement wall, where it connects to an exterior mounted exhaust fan. From the fan, an exhaust pipe runs up at least 10 feet above ground level, and 10 feet from any windows.
Pictured is a FEMTOTech Continuous Radon Monitor (CRM-510). This machine runs 48 consecutive hours and takes a measurement each hour; at the end of the 48-hours it calculates the average reading. If this reading is 4.0 pCi/L, it is recommended that the residence be mitigated. We also have to have these monitors calibrated annually. It is important to have the machines calibrated to ensure the most accurate readings.
The article I chose was simply titled “Radon”. It was a very informational article regarding radon gas. Radon is an odorless, tasteless and essentially invisible gas that may be a problem in your home. Radon gas is the second-leading cause of cancer (after smoking). When a radon problem is discovered it is important to mitigate the problem. There are several different methods of measuring radon gas - my person preference is to measure radon with a CRM-510 machine. Honestly, I had never heard of radon until I started in the inspection field. It is a silent killer.
This continuous radon monitor was installed in the lowest livable level of the home. It is at least twenty inches from the floor. The wall behind it is an interior wall. It has been set up for a 48 hour test. Closed house conditions were preserved for at least twelve hours before testing.
I am using the imaged titled Sealing Radon Pipe Through Plastic Sheeting. It shows how two roof vent flashings are used to seal the vent stack for a radon mitigation system to the plastic sheeting in a crawlspace. One is placed under the plastic sheeting. The other is placed over the plastic sheeting. They are screwed together with sheet metal screws, and the top flashing is sealed to the plastic sheeting.
When ice damming is present you have to take in consideration how the attic is doing its not just about the condition of the roof you have to make sure that the attic ventilation is not cover by snow because if the water gets under the shingles and start to leak into the roof on top of it also not being ventilated correctly you are going to have some mold in the attic.

I found this photo to be a simple diagram to help explain the breakdown process of how radon is created, and to show how it makes its way to the home. Should be helpful as an addition to reports when recommending testing to clients.
I chose to read the consumer targeted radon article. It is a good brief overview with an emphasis on the health related risks associated to radon exposure. The article is a good quick read and could be useful to help clients decide whether a radon test is appropriate for their home.
Image is of an open, uncapped and unused well located in a basement built in 1920 that is on the same level as a portion of the home with living areas in a daylight basement. Due to the possibility of Radon coming up and into the basement through the open well casing it would be prudent to test the water for Radon as well as the basement if levels were above 4 pCi/L in other areas of the home.
Doing Damage During an Inspection: It’s your job. Very well written! When I first read that title I thought “What?”. But if you break something by normal procedures or operating controls then you’ve just discovered a defect, which is your job and you may have saved your client from future grief and/or harm.
This 4 inch pvc pipe in the attic is part of a passive radon system that the owner had installed. The system is about 10 years old according to the property disclosure forms. The problem is that the installer never finished the job by punching the pipe through the roof and flashing it in to prevent leaking.
Abrasive blasting versus the traditional scrubbing and sanding for mold remediation. Mold removal was a laborious and time consuming chore before the use of baking soda or dry ice combined with the proper air pressure and nozzles to blast mold away. Using dry ice as the blasting medium means less clean up because the dry ice evaporates as it warms.
When setting up a Radon test you have to make sure that it is being set up where it will be undisturbed for forty-eight hours. The conditions in the home must be this way twelve hours before testing and through out the duration of the test.
There is a crack in the slab documented in this picture which can serve as an entry point for radon gas. This crack should be sealed to reduce the risk of radon gas entering the living space of this home.
