MG Remediation, Inc., has been in business for over 25 years performing Vapor Intrusion and Extraction for VOC's along with Radon Mitigation. We are a full service environmental contracting and construction company. We offer radon mitigation throughout all of the Western Regions of the United States. All of our systems are guaranteed to lower you radon levels. To date, our thousands of installation have lowered the levels from a high of 219 Pico curies Pico curies/liter to .4 Pico curie/liter. Furthermore, our post mitigations system radon levels have never gone above 1.9 Pico curies/liter!!! If you need any radon mitigation done give us a call today!

"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."

Experts with water, mold and fire restoration services. Our team has over 10+ years of experience and is certified with IICRC which is the firm that sets the standards for remediation. Every team member must pass a background check and a drug test prior to employment. Our goal is to ensure our customers are completely satisfied and we leave their home cleaner than when we started the job.

"Who would think that having mold removed from my crawl space would be such a positive experience. I contacted Restoration 1 through Angi's list and they were prompt in coming to my house to assess the damage . They provided pictures and videos of the damage. All the way through the remediation and eventual clearance of the mold was done with the upmost professionalism. I was updated daily by Janny Ferrer (CEO) and there were no surprises awaiting me when I return to the residence. The quality of work and reasonable price was way above my expectations. The three technicians I would like to personally thank are Jose, Bryan and Jake. They did an awesome job. I would recommend this company hands down to anyone having water damage to their home. What a pleasure working with such a professional and caring company as Restoration 1. Thank you!"

All Clear Environmental is Southern California's one-stop solution for asbestos removal, lead abatement and mold remediation. Our team of licensed professionals has over 100 years of combined experience in the thorough, discrete and environmentally responsible removal of hazardous materials. If you think that your property may be at risk for containing asbestos, lead or mold, we can provide you with the most cost-effective solution. And you can be sure that when we're finished, it will be All Clear.

"Abatement and Remediation are not for the weak or weary - whether managing a personal or professional project, proper containment practices and efforts are essential. I will forever recommend and promote All Clear Environmental - a family-run business with hands-on customer relations. Larry Enos and his son, Beckett, put forth great effort to communicate, assess, and manage the process in good faith. All Clear's team of Rigo et al, handled the physical abatement and remediation, in our home. Rigo and his team made us feel 100% safe, confident, and secure throughout each stage - which was no easy feat with children and pets, in a home. And while there are no accolades for being second-round mold recipients, we hit the jackpot in working with All Clear. We have worked with other companies only to be left with poor communication, a tendency to be overcharged, and dishonesty. Beckett was available almost 24/7 to answer questions via text and live calls. When I felt doubt, Beckett made time to discuss alternative avenues and ensure our best interests were at the forefront of every decision. I recommend All Clear Environmental to friends, neighbors, and strangers with 6/5 stars. Your house is your home - and mold is personal. A company that recognizes the need to love your home well, is a gem beyond measure. Thank you, All Clear Environmental - good people attract good people! Gratefully, Jackie"

FAQs for radon gas abatement projects in San Francisco, 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.
