I had spoken to Jerome early in the process for an estimate, and he came prepared with all sorts of literature about what brace and bolt consists of, the soup-to-nuts process and general earthquake preparedness. We had to get multiple quotes, but other contractors were either dismissive or way more expensive. Once we decided on Quakebusters, Francisco was tremendously patient with us and guided us through the entire process and helped with advice about how to gather the information we needed. The crew took exactly as long as they anticipated, arranged their own porta-potty facilities, were punctual, arranged for the special and city inspections, worked with our schedule and cleaned our crawlspace nearly better than they found it! Quakebusters were also transparent that there were cheaper options than to go through the official EBB grant process, but we decided spending the extra money for peace of mind and to have permits was out best option. Thank you guys so much! Who you gonna call? Quakebusters!

Review of my retrofitting project…read more by Montclair Construction C.Z. Nie 1/6/2026 We owe a house in El Cerrito about 800+ sq. Ft. We noticed the floor was slightly sloping towards the SW corner. We decided to ask Montclair Construction to take a look of the problems and provide us some correction advices. We made an appointment and Mr. Justin Caddy showed up right on time. After he checked out the house, he suggested to do a floor height level survey to quantify how bad the problem was. Mr. Justin Caddy and Mr. Nirmal came and did the survey. Luckily, the sloping was within the tolerance, but there definitely needed some work to stop it from getting worse. Mr. Justin Caddy proposed to do the following jobs : 1. Retrofitting by install more girder beams under the floor as well as piers. This would support the floor much better. 2. Install a French Drain, which would guide the water away from the foundation so the rain water would not affect the soil under the foundation. 3. Since the house was only bolted down on the foundation but did not have shear wall installed, might as well to get the shear wall installed included in the project. Because the crew would be working in the crawl space anyway. We thought these suggestions made great sense, so we asked them to do the project. The whole project started on 12/22/2025 and completed on 1/29/2026, which was not including the time engineers working on the plan and applying for the permit form the city. We are very happy with the results for the flowering reasons : The whole project was conducted by Montclair Construction in a smooth effective way. We did not have to deal with the engineering company, Upright Engineering, and the city. All of the paper work was handled by Montclair Construction in a proper professional manner. After the project we received a copy of the permit and the plan with no cost. During the construction period, my tenants were not disturbed (except some dust and noise), only once the crew asked for resetting a tripped breaker. Montclair Construction provided a portable potty at job site for their crew. During the whole process, Montclair maintained a superb communication. They promptly addressed all of my concerns and answered all of our questions ( since we know very little about construction works, we had tones of questions). We had used emails , text messages, and made many phone calls. We always got connected quickly. We had called Mr. Justin Caddy, Mr. Nirmal, Mr. Miguel, Mr. Javier, and office manager Ms. Diana Connolly many times, and anyone of them was always courteous and easy to discuss whatever the subject was. We had spoken with superintendent Tom while we were waiting for the city inspector to come. We must say that one hour wait did not seemed to me was too long, because we learned so much from Tom. We must say that everyone of the Montclair Construction employees we met was very professional and helpful. The project passed many inspections at different stage of the construction by the engineering company, Upright Engineering, and from the city of El Cerrito. Montclair Construction handled all of the inspections, so we did not need to be at the scene. During the construction We requested some favors from Montclair Construction, which was not foresaw at begging of the project. We asked Montclair to replace the small entrance door to the crawl space, because the old door was in bad shape. Montclair Construction ( Mr. Miguel's crew) replaced it with a new one, not just looks great, but also much stronger. Montclair did not charge for this job. At the end of the job, Miguel's crew pulled out some junks form the crawl space as city directed. We asked Montclair to haul them away, and they did at no additional cost. We appreciate very much! After the job, Miguel's crew did a good job to clean up the job site. We called for a few little things, and they all got addressed promptly. All in all, the experiences are all positive. We are very happy about the results. We made the right decision to ask Montclair Construction to do the job. We are very appreciative and thankful for Montclair Construction's professional help.

It was a big project involving drainage and a complete rebuild, and they handled every part of it flawlessly. The crew was fantastic--courteous, kind, and incredibly diligent. Even my next-door neighbor commented on how impressed he was with their professionalism. No litter, no loud music, no parking issues--just a great construction team doing excellent work. A special shoutout to Robert and Diana, who guided me through the entire process and answered every question along the way. Orlando, who oversaw the project, was also a pleasure to work with. Their communication was excellent, and they kept everything on schedule. I wish I remembered the names of the two main guys on the crew, because they absolutely deserve recognition--they were A+ workers, always hardworking and always smiling. I highly recommend Montclair Construction. They get a 10/10 from me--an A+ rating. This is one very happy customer, and I'll definitely use them again for my next construction project. C.
