Education, one of the key and most important ingrediants to quality. View the pic posted. Even if a homeowner wanted us to do this we would not, because we know what the outcome would be. This is what you can see. I wonder how the inside of the attic and the bottom of the roof are fairing.

What you see on the soffit is what is coming from under the basement slab. Moisture, Dirt and everything else that is in the soil. Besides that it looks horrible. Yuck.

Our installers are all highly trained and educated. This helps them to maintain their certification. Have we ever installed a system below the roof for aesthetics? Yes, with a signed waiver from the owner. And, we make sure the cone of air coming out of the pipe would not be able to blow moist air onto any surfaces.



Mold, Dirt and Everything Else that is under the slab in basement.



But it’s a Moisture System

A great side benefit to getting a Radon system is that it can help reduce moisture in the basement, which in turn will effect the whole house. If you have gravel as a sub slab material or capillary break under the basement slab it will have the best effect, just as it will also get you the lowest Radon levels vs. just having sand or clay under the slab. If a Moisture system is installed just to reduce moisture it still has to be installed properly.

What I have seen the past few years is companies going into a home that has a Radon issue and installing a system incorrectly and then calling it a “Moisture” system. Thinking they don’t have to install it up to standards because they labeled it by another name. I cant name names but the certified company that did this a few months ago has a a location in North Appleton and Green Bay.

No matter what you call the system, when you are venting soil gases, which you will be doing with a Moisture system, the same standards have to be met/kept. The fan cannot be in livable space, including the basement. And, the vent has to be a minimum of ten feet above grade and two feet above any openings that are within ten feet of the vent. These standards are in place to protect the occupants from any high exposures to any soil gases. Even if you have not tested high for Radon, and you get a Moisture system high levels of Radon will be coming out of that vent.

Lets say you tested at 2.0 for Radon, which is well below the 3.9 or below threshold for a pass. Well, that is what made it into the basement, moving through the concrete slab. What is under the slab could be 200, and that is what will be coming out of that vent and fan if it leaks while inside the home or basement. Not to mention whatever other gases may be present.  The standards are in place to protect you. So, if you are venting soil gases make sure the system meets standards for your protection.


Vent Cannot be at ground level

Always Check Your Sump Pump

Always check your sump pump for proper function. Especially when snow starts to melt and the spring rains come. This is why we install clear lids.

Here are some very important reminders when it comes to sump pumps. 1, always remove your small extension hose in the late fall. If you do not any water in the hose can quickly freeze and block any more water that may need to be pumped out. Even though we may have a thaw period or some rain. Many pumps will activate in the winter and if the hose is froze you will get water in your basement. The rubber coupler, or check valve can come off because of the back pressure created with the frozen hose. Just leave the hose off or put on a minimum 3 inch solid pipe for winter months.  2, make sure you have a way of checking the water level in your pit. We use clear lids so you can see in the pit. I don’t mean lift up the float and activate the pump, but just be able to check the water level in the pump. Especially when there is rain, or a winter thaw.  If the water rose enough to activate the pump and it is running without water being taken out you probably have a frozen pipe outside.


Hire a Radon Company that knows the Codes

Hire a Radon company that knows the codes.

Just saw this system. Look at the two pics. The installing company did not know what the building codes are. We are not allowed to cut out the bottom of a joist. It takes away the structural integrity of the joist. The way it has to be repaired is to place a steel plate on both sides of the joist and then bolt them onto it. The will no longer allow space for the Radon vent. The owners, who are selling the home found this out upon the home inspection. The piping on the other side is now behind finished space, which means they have to cut that apart and repair it also to remove the piping. Then a new Radon vent has to be installed from scratch. All because the other company did not know what the codes were. This comes down to proper training when getting certified to install Radon systems. That is the beginning. From there one has to be trained on what they can and can not cut through. Do your research. Hire a company that has proper training. We at Radon Specialists of Wisconsin have. In addition to being certified for Radon I am also a licensed builder. We know the codes.


Home buyers Beware of What Radon System You are Getting

Home buyer’s Beware!

This has happened more that past month or so, so I thought I should address it. The Realty market is hot, and contingencies are being thrown out the window, Radon testing being one of them. For those buyers that do get a test please, please stipulate in the offer what Radon company you want to install the system if the Radon test should come in elevated. And just a side note, my wife is a Realty Agent. Like all agents she works on commission. Most agents out there I believe do a good job. What the listing agent is dealing with, and they work for the seller, is someone who doesn’t want to have to pay for any repairs, especially a Radon system. They are getting no benefit out of it, except they will be able to sell the home. I have always told sellers to get a good system so the buyer is happy with what they end up with. Most sellers don’t do that. We lost a job recently, well it happens all the time, based strictly on price. The other company gave a very low price, which means corners will be cut as much as possible. To do it right and make a profit you can’t possibly offer the cheapest price. I wish I could. A good, fair price can be offered based on volume. Anyway, a few weeks ago a seller hired a company who offered a much lower price. Once the buyer saw what was done, they told their agent I am not going to buy the house with the way the Radon system was installed. Long story short we were called to rip out the first system and install a new one from scratch. We were able to use the existing fan though. I guess I should have titled this differently because the seller had to pay for a Radon System twice, and almost lost the sale of the home. Ask your agent to be able to chose the Radon Company, and don’t let the sellers counter out of it. If they counter and you accept be prepared to get the lowest quality system money can buy.


Test for Radon Gas with New Home Purchase

Buying a new home? Make sure to test for Radon. Don’t get stuck with a home that has high Radon and then end up paying for the whole system.

With the hot realty market it has really been a sellers advantage. Multiple offers come in on new home, some higher than asking price and contingencies are being tossed out the window. Radon testing being one of them. Buyers don’t want to lose out on a home where there are competing offers. This last year we have seen Radon testing go down quite a bit because of this. I get this, but if you have recently purchased a home and didn’t ask for a Radon test remember to get one after you move in. It is easy to forget to test for Radon Gas after you move in. Unpacking, decorating the home. It’s all busy work and then your beat at the end of the day. Once your settled in get a Radon test. Don’t be the one to find out you have high Radon Gas ten years from now when you go to sell your home. Once the damage is done from Radon Gas it is irreversible. Radon Gas has causes Lung Cancer, Leukemia and has been linked to Skin Cancer. If people could see or smell Radon Gas it would be easy to remember. But we humans cannot sense it. Put a post it on your fridge to remind yourself to get the Radon test. It could save a life.


Great Team for Wisconsin Radon

This is our great team.

2017 is almost at an end. We celebrated last night with our employees and a few friends. I don’t feel we have the best employees who work in Radon, I know we do. Every single one always wants to do the right thing, be upfront and keep our name spotless. Not one of them would ever do anything to compromise that. From our team to all our past, and current customers we want to thank you for supporting our business. And we hope that the upcoming year will be a great one for all of us!

Great Team


Army Reserve Radon Systems

This is the Army reserve center in Neenah. Just down the street from our shop/office.

When the Army comes calling, you say “yes sir!”.  We recently had the pleasure of working for the Army and installed five active radon systems at the Army Reserve Center in Neenah. After coring through 3 ft. thick walls my guys were tired. But we finished the job. We are letting the active radon systems work for a few days then performing post mitigation Radon tests to confirm new levels. These pictures just show the dedication and skill that my installers have. I truly believe that we are the best Radon company in the country.

Radon Fans Have to be Mounted Vertically

Just wanted to share a picture of a radon system installed in our area, by a certified radon company. Radon fans have to be mounted vertically. Otherwise, the inside fills up with water, which will end the Radon fans life early. Piping on the outside also needs to be vertical on a Radon system. A foot or two or horizontal piping is OK if really needed, but for the most part, it should go vertically up the side of the home. If the Radon vent pipe is run horizontally outside for a long run it too will fill up with water and become ice in the winter. By looking at the picture you can see that the area in the basement had to be finished off where they wanted to run the pipe. I get running it next to the chimney for aesthetics, but the method is incorrect. Sometimes tough choices have to be made. They could have run it vertically, then painted it to match. Once a Radon system is painted to match siding they blend in very well.

A Bigger Radon Fan? Bigger is Better Right?

A gimmick that has gone around for a while with Radon systems and companies trying to convince you to go with them is to up-sell you a bigger Radon fan. In our society bigger seems to always be better or the thing to do. Well, with Radon systems there is only a few cases when a bigger radon fan is the right move. First, if there is very tight soil under a basement slab such as sand and or clay then a larger vacuum fan can be needed. Extra vacuum power can move air in a tight soil condition whereas a high air volume fan, that is made for low resistance is not the best fan to use. Second, when there is a very large square footage slab, and I mean large like more than 4000 square feet it might be a good idea to use a higher air volume fan. This is mostly in commercial applications. So, if you are a homeowner and you have a 1000 to 3000 square foot slab in the basement and a Radon company is trying to sell you a bigger radon fan to give you lower Radon levels you are being scammed. Radon does not work that way. You actually don’t need to move much air to lower Radon. You just need it to move from footing to footing. A regular air volume fan will more than do the job if installed properly. Think about it. If the Radon company really cared about you, wouldn’t they install the right fan to get you the best results right away? It’s easy for them to scare you to get a “lower Radon guarantee” when it is not necessary. We offer a guarantee of 1.0 or lower for a little more money, but it does not involve a bigger radon fan, and to be honest, in most homes it’s not needed. It includes more diagnostic testing should the first post-test come in above 1.  And I tell customers that. Most homes with the right fan and piping, and gravel and or drain tile system will get below 1 Pico curie right away. Instead of offering you a fan upgrade, why not ask that they just quote you the best system with the right fan in the first place.
