What is Radon?

According to the CDC, breathing in high levels of radon over time can cause lung cancer. Radon is the second most common cause of lung cancer, behind smoking. Radon is a naturally occurring gas formed by the breakdown of uranium in rock and soil. It seeps in underneath structures through tiny holes or cracks in the foundation where it becomes trapped inside. Because it is odorless and colorless, it isn’t easily detected by smell or look, making it impossible to know if it’s rising to dangerous levels in the home.  Protect Your Family From Radon today by having one of our certified Radon technicians test your home.



The national indoor Radon level is 1.3 pCi/L. Over 50% of homes in St. Charles test higher for the level of Radon in the home.


Within just 48 hours, our tech’s can get you a full report on the Radon levels currently within your home and a plan of action if need to correct them.


Just like annual maintenance on your homes systems, testing your home for radon can have a big impact on your family’s overall health and comfort.

How People are Exposed to Radon

People are most commonly exposed to radon indoors. Radon gas enters a home through cracks in the floors or walls, construction joints, gaps in the foundation, around pipes, wires or pumps. Radon levels are typically the highest in the lowest level of your home since it is the closest to soil and rocks.

How Radon Testing Works

With radon being the #2 cause of lung cancer, behind cigarettes, it’s incredibly important to know if your family is being exposed to high levels of radon gas. Proactively testing for radon at least once per year can give you peace of mind. Here’s the process:

  • Place test kit in the basement at least 20 inches off the ground and at least 3 inches from any windows, exterior walls, or entryways, avoiding drafts
  • Let the device run for 48 hours unplugged
  • The device will read the current radon level as well as record the highest levels that it detects over the course of the testing period

When to Test Your Home

  • If it’s never been tested or radon levels are unknown
  • When preparing to buy or sell a home
  • Before and after any renovations, especially after making any repairs to reduce radon levels
  • Before making any lifestyle changes in the home that would cause someone to spend more time in the basement or lower level (like converting a basement to a bedroom)

Radon concentration in air is measured in units of picoCuries per Liter (pCi/L) or Becquerels per cubic meter (Bq/m3). The Missouri Department of Health and the EPA use 4 pCi/L as a recommended action level. When testing indicates that the radon level in the lowest primary living area of the home is at or above this action level, they recommend that the homeowner take corrective action.

The Solution

To alleviate higher levels of radon from entering the home, a radon mitigation kit can be installed. A hole is drilled through the concrete slab where the radon sits in the dirt and gravel underneath the home. A PVC vent pipe is placed over the hole and runs through the foundation to the outside where a fan pulls the gas from under the home to be vented outside, above the roof. After the mitigation device has been installed, the home must be re-tested to ensure that radon levels have dropped.

Here at Budget, we are certified through Spruce Environmental Technologies for both radon testing and mitigation. Don’t leave your family’s safety up to chance and give us a call today at 636.887.2800 to set up your home’s radon measurement test.

Always love using Budget. We used them in the past around Christmas time and they ensured we didn’t go without hot water. This week our Furnace went out ( it was 31 years old) and they were here the same day to assess what needed done. Then returned the next day to install our new Furnace. Everyone there is so easy to work with. They are professional, their techs are professional, knowledgeable and only have good things to say about the company they work for. We worked with Gabe and Mike. They were both excellent! Kaitlin in the office only made our experience even better! Thank you!

- Heather S.

Contacted the office requesting a quote for a new Furnace and AC unit and they sent out Keith the following day! He was very kind and willing to answer all of our questions and even provided a quote the same day with a cash discount! It took about a week for our parts to come in, the installers arrived on time and were quick to get things rolling. They completed the job quickly and cleaned up after themselves when they were done. Would definitely recommend to anyone needing a new AC unit or furnace to use this company they were wonderful to work with!

Budget is the ONLY company that I trust for plumbing repairs and maintaining my heating/cooling systems. They have done work that others couldn't handle and at a decent price. I will continue to use them for whatever services they offer. I appreciate everything they have done for me so far.

We purchased our HVAC system from Budget in 2019 and have been very pleased with it overall, except recently the AC unit was making a strange noise. The unit sits on an elevated pad which I wanted it to be out on the ground at install but the tech did not have time to change that out. He told me that he would do it at a later date if it bothered us. Budget was quick to fulfill this request and Justin came out to put the unit on the ground. It looks so much better now, but the best part is it is now so quiet when it runs!  Beyond happy with the 5-star service the team at Budget provided. Thanks so much Cassidy and Justin!

Our Hot Water Heater just went out on us unexpectedly and Budget was able to come out the same day, assess everything and lock me down for a time, early next week. The customer service from Jennifer was above and beyond. She was so nice and helped my family. Isiah was very smart and knowledgeable and took the time to explain what was needed and the process. Would definitely use them again.

- Joseph C.

The technician showed up early and solved the issue right away. He was happy to address my questions and concerns regarding my aging HVAC. I was impressed with how knowledgeable he was. Per my request, he sent replacement estimates ranging from good to premier. This is the second time I’ve had great service from Budget.

- Amanda K.

I had a Water Heater installed today. Not only was it quality work, but the installers were professional and courteous. My house poses some unique problems as far as plumbing goes, but the installers handled it with ease. 10/10, will definitely use Budget again.

- Kelly G.

The Faucet in my condo was not working properly, the water flow on the hot water side was very small. Budget sent technician Tim to solve the problem and he replaced the Faucet in an amazingly short amount of time and patiently walked me through the Drainage System. He was highly skilled and efficient! Strongly recommend Budget!

- Tricia G.

We have had Budget out a couple times and they are always very professional, quick to come out once called and helpful! This past time it was Mike and he was great! Every time we need service on our HVAC we will continue to use them. Thank you for all you do!
