Jony did an earthquake retrofit for me through the state's EBB program. He had a great (the best) price, handled all the EBB paperwork, and the crew completed all the work and had the inspection/permitting done right on time as expected. I had some paperwork issues with insurance (unrelated to his work) and Jony helped me deal with those as well. read more

Jony and his team were amazing. Professional, communicative and thorough. I've recommended JM Building to all my neighbors.

The recent experience I've had with JM Building & Construction Inc. retrofitting my home (through the State of California's Earthquake Brace + Bolt program) has proved to be 100% positive. It's been everything I'd hoped for. From submitting a fair and reasonable bid at the outset and communicating with me on a timely basis... to the actual foundation seismic retrofitting/bolting work itself, inspection, and completion of all relevant forms: at every step along the way this company has done exactly what they said they would do. They have gone about their work in an extremely professional manner. Among the reasons I selected them for the job in the first place was the experience they had in doing this kind of work and their consistently positive reviews. This experience showed throughout the process, and in my case they definitely did NOT disappoint. For anyone looking for a truly first-rate company to provide retrofitting services, I would enthusiastically recommend JM Building & Construction Inc. without the slightest hesitation. read more

This could be a daunting process especially since it is not something most home owners know anything about, but Jony was good at keeping me up to date on each step of the process. It takes longer than one would think with permits and approvals, but he was on top of it and got back to me when things were ready to proceed to the next step. The work was done quickly and seemingly with efficiency. I would certainly recommend him for any retrofit projects. read more

Jony and team were such a pleasure to work with! They did earthquake retrofit work on my home and took a lot of great care in doing the work. From beginning to end, they were upfront, clear, and thorough and provided great perspective.

The heavy winter rains finally did in a portion of my basement wall that had been cracked and leaking for several years. My house is a 1910 Craftsman and the foundation walls are unreinforced concrete. I got 3 wildly different bids. One company wanted to lift the whole house for $80k and the low bid just wanted to inject epoxy into the cracks. Jony, the owner of JM suggested that the existing wall should be demolished and a new one constructed. A deal was made and the work began a week later. JM is a small family business and so Jony, Ion and Manuel worked on it together. Ion ended up being the main guy throughout the job, excavating, shaping the rebar and building the forms for the new wall. On the day of the pour all three of them mixed 50 bags of cement and got it into place. The new wall is more than twice as thick as the old one and I'm confident that the leaking problem is solved. Communication with Jony was a breeze throughout this job. If he didn't pick up immediately he always called me back within minutes and he took care of any details that i asked about. When the job was done all dirt and wood debris was removed and my property was left looking good. Based on my experience I cannot recommend JM more highly. They did a great job for me. read more

Ever find yourself short on time, but feel so strongly about a business that you need to leave a five star review? That's where we're at with JM Building & Construction. Let's do bullet points: * Jony was the only foundation expert available for an inspection during the weekend. After I had called him Friday night, he was onsite for the inspection Saturday morning. His price for the inspection was very reasonable too. * Jony's inspection report was well written, highly detailed and contained helpful pictures snapped under the house. * Price quoted for the foundation repairs looked good. * I told Jony we planned on contacting him a few months later to schedule repairs, "after taxes." He was fine with that. No pressure, very flexible with scheduling. * Now Jony and team have completed the repairs and they look fantastic. We feel a lot better about the house. * Bonus: Jony was able to provide guidance relating to expansive soil. We put in rain gutters (from a different local business we found on Yelp, Edgeline Rain Gutters, thumbs up there as well btw... sigh I need to set aside time to write another 5 star review) after discussing the issue with Jony and are glad we did so. Thanks Jony! The next time we need a periodic foundation inspection we are definitely calling you. read more

Jony & his team retrofit my house (on a hill). He had a reasonable price, did all the ppw for me, and had quick answers to all my questions. He made all adjustments I asked. He did not pressure me to make any payments until the work was done & completely signed off on which I really appreciated. Thanks again! read more

Jony was very knowledgeable regarding foundations. He took his time inspecting my foundation and gave me a reasonable estimate. He showed me pictures of the issues I had, and provided me with images to back what he was saying. I had one issue that is going to need to be addressed, but he said I have a few years left to address it. We scheduled a month after the inspection, and he and his worker showed up and finished the job after a couple of days. read more

Great service above & beyond will highly recommend jm building &construction to family & friends for retrofitting.....

John is very knowledgeable about his field and construction in general. He helped me determine what the issue was with a badly cracked corner of my house that was gradually being crushed by a adjacent retaining wall. He helped me determine that I actually didn't need an expensive repair. I appreciated his honesty and candor on the matter, thus saving me the hundreds or thousands of dollars. I would trust him completely, an honest person. read more

I am really happy with the results of the project, the quality of the work was excellent and there was no problem passing the final inspection, and the quote that I received was one of best for the project. read more

Great job and fast responds! Jony is professional and reliable! I would Recommend them to others ! !

I needed a retrofit done and found Jony through the EBB site. He came over to do an estimate and explain what he needed to do. His price was reasonable, and he was easy to work with. His crew was punctual every day, cleaned up everyday and focused on their work. JM building and construction is an honest, hard-working company - I would recommend them to everyone. read more

If everything in my life went as smooth, efficient and just plan amazing as the interactions with Jony and his crew at JM Building & Construction for the EBB program project it would be a game changer!

Jony was great to work with- he handled all the ebb paperwork, got the job done, was on time and professional. Wish more contractors were like him. read more

We just bought a new home and choosing to work with Jony has been our best decision yet. During our escrow period, we scrambled to find foundation companies to come out and give us an estimate so that we could put together a proposal to our seller. JM Building was one of the very few companies that didn't charge for a complimentary consultation. (Other companies charged $250). We had 2 other companies, beside Jony's, come out to take a look at our home. The other 2 companies barely peeked their heads under our crawlspace and wrote us an estimate off of "what they could see". Jony is the only one who got into his gear and spent 30 minutes crawling around under our home taking photos of problematic areas and making sure that he covered every inch. The thing we enjoyed most was that Jony never once tried to upsell us. Because the foundation of homes are hidden and we will never be able to see what's going on under, it was important to us to find a company that could be honest and transparent with us. From a sales rep's perspective, in a situation like this, it would be really easy to upsell the customer and add on things they don't necessarily need. Not with Jony. We went over main areas of concern, and which parts of the home were an absolute necessity to fix and which were just recommendations on his behalf. The quote came within 24h after our consultation and he listed out a few options that we could look into. Option A consisted of the necessary fixes that we were already aware of and Option B were his added on recommendations - but entirely up to us on whether or not we wanted to do now or later. Jony never gave us any pressure and didn't make us feel bad for not picking the more expensive and unnecessary option (which, most companies do). Jony and his guys completed the work on our home in 2 days, during the time frame which they promised. They showed up on time each morning and worked diligently. Not to mention, his guys were respectful of our property and CLEAN from beginning to end. After they were done, Jony showed us photos of all the work they had done under the house. This was so important to us since we will never be able to see this for ourselves. It was refreshing to work with someone so honest and someone who clearly has his customers' best interest at heart from beginning to end. Not to mention that his pricing was by FAR the most competitive. I'm recommending JM Building to anyone I know who needs a foundation expert to come and assess their home. Our foundation is literally what holds us up everyday and we want to feel safe in our home. With Jony, we were able to do just that and we are so thankful to have had the opportunity to work with him! read more

You can never get a hold of anyone. You call talk to people and they don't know anything. It feels like the owner is completely unaware what customer service. read more

JM Building & Construction did some excellent foundation work on my house built in the 50's. The house's foundation had several cracks and multiple posts had shifted. They corrected the cracks and retrofitted the foundation with seismic braces. While foundation work is never "cheap," JM Building & Construction was competitive with other quotes we received. I really appreciated Jony, the owner, being on site to review and go over the work with me. Would definitely recommend. read more

Jony and his crew did a great job with our earthquake retrofit/brace and bolt project. His initial quote was very competitive, the work team was punctual and everything was completed within the promised timeframe. Most importantly, the work passed inspection with the city official had to sign off on the project. We will use him again without hesitation for our next home improvement project. read more

These guys were outstanding from beginning to end. Jony really could not have been more responsive, helpful, or generally pleasant to work with. He communicated openly about different options and their costs, and really never seemed to be trying to up-sell us. The estimate was thorough, the work itself was done as painlessly as one could ask, and the cleanup and paperwork were smooth. If only all contractors were half this good. read more

Jony was great to work with. Never felt the pressure from him compared to other contractors who try to up-sell work. Easy to get a hold of with questions. He first came by for inspection in March and was flexible for a later date in July for the repair. I liked to get to know my property better and requested to have him show me the repairs through a walk-through in addition to the phones. Jony happily guided me through the crawl space and explained the repair done. I would recommend and call again if any other work is needed! read more

After weeks of searching for help to fix an access issue in the crawlspace under my hundred-year-old home, I'm so grateful to have found Jony and JM Building. When others consistently presented me with their problems, excuses, and the dollars associated, Jony came in with integrity and expertise. His team was fast, effective, and 100% professional--and they got the job done beautifully. I would hire JM Building again in a heartbeat. read more

We asked four companies to give us an estimation. Jony gave us the most reasonable price. It is very easy and comfortable to work with him. He always listens our opinion patiently. He also suggests us how to prevent further damage our foundation. His cute uncle tried his best ( I wish I know more Spanish) to guide us how to reset our rain gutter to let rain flow further away from foundation. He even tried face time with his friend, and asked suggestions how to make surrounding areas of foundation easy to flow rains. I feel his our friend, not a contractor. For all contractor we worked with, he is the best. we just want to say Thank you Jony. You are a nice man. read more

Jony and his crew are Rockstars in my opinion. Professional, on time and just gentlemen. JM Building did my inspection and now that I moved into the home, Foundation work was top of mind. I looked no further than sticking to Jony! I reached out two weeks ago and they completed the work over this past weekend. The prices quoted during the inspection remained exactly the same. Probably one of the very few companies out there with integrity. I HIGHLY recommend! read more

Jony did a great job adding support beams under our house! The tv would shake whenever I'd walk past it and now our floors are solid as a rock! No more shakey tv! Jony gave me a good price, a realistic estimate of how long the job would take, and before & after photos showing the professional workmanship he and his crew did. He's a man of his word and I wholeheartedly recommend him! Thanks Jony! read more
