RM1 Construction - Retrofit and Foundation Repair

I recently worked with Monnix on a retrofit and RM1 construction project, and the experience was outstanding from start to finish. Their team was organized, professional, and extremely knowledgeable about the entire process — from engineering, permitting, and city compliance to the actual execution of the work on-site. They communicated clearly at every step, handled all inspections smoothly, and delivered high-quality workmanship. The project stayed on schedule, the job site was kept clean, and their crew showed real attention to detail. As a contractor working alongside them, I truly appreciated the level of coordination, teamwork, and reliability they brought to the table. If you’re looking for a company that knows what they’re doing when it comes to retrofit or RM1 work, Monnix is on

Fantastic! From the super friendly manager, Monnix, to their hard working amazing crew. They all delivered a high quality of work at a very fair price! And most importantly, they all did it with integrity!! If you need any foundation work then don't hesitate to use them. Highly recommend!

Monnix and his team provided excellent service from the moment we inquired about the EBB earthquake bolt program until the moment we signed off on the final inspection. Their team is one of only two I have ever worked with (and I have worked with many) who fulfilled all of their obligations on time and on budget. Highly recommended!

RM1 did a terrific job on our Earthquake Retrofit, including all of the filings with the California Earthquake Brace & Bolt organization. Their work people were extraordinarily gracious, and the work was performed in a very timely manner. I recommend them highly

I'm a home owner in the Los Angeles area specifically the San Fernando Valley and these guys helped me by seismically retrofitting my home. They were super quick and they beat every other contractor's price. If you need any foundation upgrade or repair like seismic retrofit, they're the best guys to go to.
