"I do not recommend MG remediation to anyone looking for a reliable and conscionable contractor. Carlos and his team not only took about 3 additional weeks to complete ceiling paint, the paint they did was nowhere close to acceptable and they created damage to our house along the way. When confronted with the imperfect paint, they blamed the imperfections on the way our ceilings were built. When confronted about the extra delays (keeping in mind that the last week or so on the job they started coming only few hours to work as if our project was kind of a hobby of theirs that they show up to during their free time taking no consideration to the fact that we told them multiple times that we currently are homeless and they already exceeded the timeframe they provided us with), they blamed me and my husband for â rushingâ them which led to imperfect paint and delays. Due to the damages to the walls that they created, we had to hire other painters to paint the entire house. They also scratched and created dents in our new floors and in multiple rooms. Their excuse around that is that they usually come to a house and complete their work first which is bound to create damage and then the rest of the contractors come in. They basically take the contract signed as an excuse and cover to create all the damage they please in your house. On top of all that, the communication was very poor all along although we were promised daily updates and pictures. For all these reasons above, I cannot recommend MGM to anyone."

FAQs for radon gas abatement projects in San Jose, CA

The only way to know whether your home or water supply contains radon is to schedule a professional test. A qualified radon inspector will collect samples, deliver lab-verified results, and explain the findings for $150 to $800. Once you know your exact levels, you and your radon mitigation pro can choose the right system and tackle the problem before it affects your family’s health.

Both roles tackle radon, but they focus on different steps. Inspectors test your home, interpret the results, and determine whether levels exceed EPA guidelines. Mitigation pros design and install the system that lowers those levels. Some companies do both, but the skills and equipment differ, so always verify that the person you hire is properly certified for the specific service you need.

Installing a mitigation unit fixes radon problems by reducing indoor gas levels to established safe standards. A system designed and installed by a mitigation expert, tailored to your home's specific layout and foundation, guarantees effective radon reduction. This expert installation ensures consistent performance over time while safeguarding your indoor air quality.

Open windows and doors do not reduce radon levels because they trigger a pressure imbalance that draws radon-laden air into your home. This practice fails to control radon concentration and can even worsen the issue. An active suction mitigation system provides a proven, safe, and effective solution to reliably reduce radon levels.

Radon mitigation systems generally last between 10 and 30 years, depending on system type and maintenance. Passive systems endure the longest because they have no moving parts, whereas active systems, which use a fan, require fan replacement every 5 to 10 years. System components, such as PVC pipes, seals, and fittings, can remain effective for decades when paired with periodic inspections and proper maintenance.

Radon mitigation systems consume between 300 and 3,000 kWh of electricity per year, depending on fan size and system design. On average, an active radon fan draws 100 to 300 watts continuously, which translates to roughly 876 kWh annually, and adds $30 to $300 to your energy bill each year. Choosing a high-efficiency fan and ensuring tight sealing around pipes helps minimize these ongoing costs.
