"In the middle of having my flooring installed, we discovered that I had asbestos in my kitchen and bathroom- the flooring installers walked out of the job immediately. I had 3 companies come and give me bids. San Diego Abatement Services was the most professional and knowledgeable. They scheduled the job the day after I called. They were polite, efficient, and did exactly what they promised to do. They were not the least expensive- but my confidence in a perfect job and the safety of my home was more important. They sent me the certificate of a clean air test so I can now finish my floors!"

"My husband and I are over the moon with the work Krugh Custom Services preformed at our house. We needed dry wall and painting done. Every employee showed up on time and proceeded professionally. They went above and beyond to ensure our house stayed clean while they were performing their work. After the work was finished Dave the owner called to ensure we were pleased with the work of his team. We will be needing the outside of our house painted in the next few month and we will for sure being hiring Krugh Custom Services for that job as well. Couldn't recommend this company enough!"

Radon Detection and Reduction questions, answered by experts

The lifespan of a radon mitigation system depends on the type of system and its maintenance. With proper care, a system can last for many decades. Passive systems tend to last longer as they have fewer components that require replacement. Active systems, which have more moving parts like fans, generally have a shorter lifespan. For instance, water filtration devices and active pressurization systems require more frequent maintenance. While the system as a whole is durable, the radon fan in an active system typically has a lifespan of 5 to 10 years and will need to be replaced. As long as the fan is working, the mitigation system should function correctly.

A homeowner can install a radon mitigation system on their own. But it’s a challenging DIY that requires a lot of knowledge about radon mitigation as well as familiarity with local regulations. You do not want to risk an improper installation that leaves the system unable to detect radon or gives it a shortened life span. Relying on a professional is the surest way to guarantee a successful installation.

Radon is a cancer-causing radioactive gas that poses serious health risks, infiltrating homes through foundation cracks and unnoticed spaces.

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.
