They really did it. Prompt and clear communication, very responsive and helpful. Robert managed everything professionally and he was even friendly with our dog. The house needed a sister foundation, which they installed quickly and painlessly. Josue did fantastic as well and the project was a success.
We contracted Montclair Construction for a drainage/flooding remediation project. When all was said and done, we had major drainage/french drains installed around our entire house, some foundation work, retaining walls, etc.The project unfortunately expanded majorly in scope throughout. Robert our GC did an EXCELLENT job sitting down with us at each juncture (candidly - some scary/expensive stuff!) and laid everything out for us. He was clear and calm and welcomed all sorts of questions and really wanted us to understand all potential avenues and pros/cons with each decision we needed to make.The work went smoothly and even with the added project changes, the timeline held.The crew (headed up by Javier!) was incredibly diligent - cleaning the site every evening, and spent about a day cleaning at the end of the project as well. They really went above and beyond. We were so impressed. Highly reccommend.
We own a house in El Cerrito CA about 800 sq.ft. We noticed the floor was slightly sloping towards SW corner. We decided to ask Montclair Construction to check it out. Mr. Justin Caddy came and suggested to do a floor height level survey. After he and Mr. Nirmal came surveyed the floor, he advised us that three things need to be done. 1. Retrofitting by install more girder beams under the floor as well as piers. 2. Install a French Drain to guide the rain water away from the foundation. 3. Since the house was only bolted down on the foundation but with no shear wall, we better to have the shear wall installed, because the crew will be working in the crawl space anyway. We thought these suggestions make great sense, so we asked Montclair Construction to take on this project. They started on 12/22/25 and finished on 1/29/26. There was no interruption in between. We are very satisfied with the outcome of the project based on the following reasons :1. The whole project was conducted by Montclair in a smooth and effective way. We did not need to deal with the engineering company, Upright Engineering who provided all the plans( a free copy was provided to us). Nor did we need to deal with the permit part. Montclair handled all the paper work.2. During the construction period, my tenants were never disturbed ( except for some dust and noise). Only once, the crew asked to reset a tripped CB. They provided a portable potty at the job site for their crew.3. through out the whole work, Monticlair maintained a superb communication with us. They clearly answered all my questions ( a lot!). By phone or by text or by email, all channels were open, and there was no wait time. They explained my not so-professional questions by using the language that I can understand.4. Everyone of Montclair's employees conducted themselves professionally all the time. They were very courteous and helpful. Mr. Justine, Mr. Nirmal, Mr.Javier, Mr.Miguel, Mr. Sam, Mr.Tom, and Ms. Diana, all are very polite and helpful.5. The project passed many inspections, by Upright Engineering and by the city of El Cerrito. We. did not need to be there for the inspections, Montclair handled all of them.6. We requested some small things that were not included in the original contract, but they all got addressed properly without additional charges. One thing was the small entrance door to the crawl space was in bad shape, Montclair replaced it with a new one without additional charges. The other was Montclair hauled away the junks from the crawl space for us, also did not charge for that job. We do appreciate vey much for their generosity.7. Mr. Miguel's crew worked very hard on the job. We can see the progress they made clearly every day. After the job, Mr. Miguel's crew did a good job to clean up the scene. We asked for a few little things, and they all got taking care of.8. All in all, our experiences are all positive. We are very appreciative and thankful for Moniclair's professional help!C.Z.

I can’t say enough good things about my recent experience with Montclair Construction and the work they did on my backyard retaining wall. 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. BeamOakland Hills---
We had structural water damage on a outer wall of our home that required replacing a header and had concerns about more possible hidden damage. Office manager Diane was prompt at receiving my call and scheduling lead estimator Robert to come out the very same day. He was polite, competent and very experienced and scheduled exploratory work for the following week. Following that initial work, construction leader Carlos and crew were able to complete the job in less than a week and did a fabulous comprehensive job with minimal disruption to our home environment and our daily routines. And the job site was spotless when everything was finished. Finding the right construction company/contractor can be stressful, but not if you contact Montclair Construction & Structural. The whole experience went much easier than I expected and I would not hesitate to avail their services for any future jobs that are beyond my pay grade!
