Concrete Foundation Repair, Earthquake Protection Service,

About us

Avant-Garde Construction Enterprise is a family-owned Bay Area general contractor specializing in seismic retrofits, foundation repair and replacement, crawl-space work, and drainage solutions for older homes and small multifamily buildings. We are licensed, insured, and have completed thousands of structural and seismic projects throughout the Bay Area. We begin with a thorough evaluation, not a quick "free estimate." A typical visit includes a complete crawl-space inspection, to-scale sketches, photos, and a detailed written report with clear recommendations, itemized options, and pricing. We can coordinate structural engineering, permitting, construction, and finish work, providing a single point of contact from start to finish. Our services include brace-and-bolt retrofits, soft-story upgrades, foundation stabilization and replacement, drainage and moisture control, and correction of defective prior retrofit work.

Was awarded by county for Earthquake Brace and Bolt (EBB) program through Alameda. I've called a few contractors but only requested 1 inspection and it was with these folks because they've provided confidence from initial contact. Extremely patient, answered all of my questions and thorough at every step of the process. Timeline for scope of work was accurate. Price felt fair for the work, thoroughness, and confidence. Highly recommend.

this is the second home we have had a seismic in the past 10 years and both were done by Matthew Gatterman and Avant Garde, he has done over 3000 of these retrofit upgrades since we first used his service extremely professionally and knowledgeable and the only contractor that took the time in the crawl space to do a complete assessment, his crew, David, Josh,Jose and Matthew were prompt and took the time to prepare a dust tunnel and the process was both clean to code, The building inspector even commented about how thorough and complete the job was done! Highly recommend this company!

I used this company for EBB grant based on a thorough search, for an honestly reviewed contractor, through multiple forums. I usually do not make positive reviews unless service excels. In this case, service expectations were exceeded. Matthew was responsive to emails, thoroughly informative about processes, and his crew was professional during work performed. The process with EBB can be a little much and Matthew pretty much connected the pieces. Thank you Matthew and crew!

It is with great enthusiasm that I write this review for Avant-Garde Construction. They performed a seismic retrofit to our home. Their customer service and responsiveness was fantastic. The crew arrived on time, finished early and cleaned up when the job was finished. I would highly recommend Avant-Garde.
