Along with earthquake retrofit (strengthening a structure’s understructure), A-FFIX offers numerous other services to help prepare homes and businesses for earthquakes:

  • Securing home, office, and industrial interiors with straps, fasteners and mats
  • Applying protective window film to prevent shattering glass
  • Providing emergency supplies and preparation advice, and
  • Restoring failing understructures beyond conventional retrofit.

Our experience securing old houses with unconventional foundations, including foundations made of brick and cracked or deteriorating foundations, makes us a leading area specialist in foundation repair. We also do all types of general structural repair, including the restoration of beams and joists, pilings, and shoring and footing systems.


We’re happy to say that our customers have been very pleased with the quality of our service and the thoroughness with which we handle our work. Read some excerpts from past letters of recommendation below, or read the full references:

“Your unswerving commitment to honesty and fairness personally and professionally were deeply appreciated. It quickly became clear that you were sincerely committed to the very highest standards of business ethics and performance. All this, and you even came in under budget!”

“We are very pleased with the earthquake retrofit done for us by A-FFIX. The construction crew was professional in every aspect and did a good job in coping with the unexpected problems that come up when working on an old (1927) house. The work site was kept very tidy throughout the job and the clean-up afterwards was excellent.”

“Bruce is very meticulous and the work he did was first rate.”

About the Products We Use

A-FFIX LLC handles many forms of earthquake preparation besides retrofit and structural repair. We secure the interiors of houses and businesses — using straps and mats to stabilize furniture, appliances and other objects that become hazardous during an earthquake — apply window film to glass to prevent shattering, and provide emergency supplies to ensure that your basic needs are provided for following a disaster.

Our company has thoroughly researched all of the products we offer to our customers, and we are confident that they are the highest quality, most reasonably priced on the market. We’ve found that Worksafe Technologies produces the most effective, most comprehensive array of seismic fasteners for both the home and office. Worksafe products are widely used by corporations around the world, and have consistently tested excellently. Our company also manages Worksafe’s online store, EQHomesafety.com (visit to purchase earthquake safety items directly).

3-M, better known for its everyday office supplies, is the industry leader in protective windowfilm. Their Scotchshield film keeps glass securely in place even after it has been shattered, and is used around the world to secure airports, highrises, office buildings, and homes.

We’ve met with the heads of Seismic Safety Products, the local company that manufactures the Northridge 2000 Automatic Gas Shut-Off Valve, and have been impressed with the superior design of their product and their commitment to customer safety.

A-FFIX has also personally interviewed the Emergency Lifeline, based in Southern California, and is confident that their supply kits, which we recommend and provide to our customers, are the best on the market.

Because we value our customers’ safety and satisfaction, we have taken care in choosing the products we use. We will go the extra mile to ensure that our customers are as safe and well prepared as they can be.
