What people are saying about us

Paul & Earline, Los Osos

We want to thank you for doing such a great job. John and the people working with him are great people and outstanding workers.

Crysty — most people don’t take time to say thank you as you have done. I truly appreciate your thank you.

Paris & Annette, Shell Beach

Please accept this gift to say a very big thank you! We appreciate the great job you and your crew did. We know this was a stressful job at times and you probably took that stress home — so please take your family out for a nice dinner on us…

Rick & Sandy, Atascadero

Thanks for the work you did out here. You and your men are hard working and professional. It’s nice to find someone that I don’t have to keep an eye on. I trust you and your guys and would not hesitate to hire you again or recommend you to anyone. The bridge came out great!

Kim, Cambria

They are top notch. They do excellent work and are very dependable.


Thank you so much for an outstanding job on my new septic tank and leach field. Throughout the job, you gave excellent customer service by giving thorough explanations to me and my brother, who was advising me. Your bid was fair and the job itself was done quickly and efficiently. Great care was taken to leave my already hilly yard in good shape, with a gradual slope near the septic, as requested. You and your crew clearly take great pride in your work and do a very thorough and professional job.

Doug & Debbie

Many, many thanks for a job well done. The news of the need to replace the septic tank and leach lines was devastating for us, but we’re so grateful that someone of your caliber and expertise was sent in to “save the day.” We appreciate the hard work and professionalism of you and your crew.


The guys just installed my lateral sewer connection. They did a great job at a fair price. I would highly recommend them. Thanks John, Jarrett and Dave.

Greg & Lisa

John has done multiple projects for us through the years and we couldn’t be happier. Years ago he did a sewer hookup when the septic tank failed. He was a life saver. At the same time he did a concrete patio slab in the backyard and a new front walkway with some fun challenges. It came out great. The latest project was ripping out our old asphalt driveway and putting in a beautiful concrete driveway. It turned out to be quite a challenge since our property is on a nice slope with nothing but shale. John and Jarrett rose to the challenge and delivered exactly what we were hoping for. We highly recommend JB’s General Engineering for all your projects.

Jerry, Atascadero

JB’s General Engineering did an outstanding job in assisting me in putting in a new leach field for our home. Due to our limited space, there was a lot of creative analysis put into design, location, and allocating the type of experts needed to get the job done. With their years of experience they were able to get a civil and soil engineer, a seasoned driller and a permit from the city of Atascadero to quickly move ahead with the project. JB Engineering then organized the work flow and my new leach field was completed in a short time span and certified by the city. Needless to say I was a happy home owner.

Holly & Dave

JB’s General Engineering is the place to go for excavation and retaining work! John, Jarett and the crew completed a challenging job on our site, efficiently and neatly. With his years of experience, John attained a successful outcome and the team even helped with some extra materials placement steps at the end of the project. We recommend John Brunz!

Mark & Gayle

We just got connected to city sewer in Atascadero and couldn’t be happier with the job. John Brunz and his crew at J.B.’s General Engineering has done. They were promptly at work in the mornings, answered our many questions and performed a rather difficult hook up through an easement on our neighbor’s property. We highly recommend this business.


I would highly recommend JB’s General Engineering for work you need done on your home. I needed to decommission my septic tank and hook up to a new sewer line, but I also needed other work done to my driveway and yard. I got estimates from several companies and JB’s was among the lowest. JB’s offered a discount to do all the work, which was a draw, and they were able to schedule me quickly, which was also a draw. The work was done with care, but efficiently, and things were kept neat during the process, which I know does not always happen and is important to me. Either John or his son was on site to lead the work, so I felt I was in good hands, and I appreciated being able to talk with them as the work went along so that I knew what was happening. I was very pleased with the quality of the result, and would definitely call on JB’s again.

Mary & Clay

A friend recommended that we call John Brunz of J.B.’s General Engineering. We called John, he returned our call and came to look at the job the next day. Within four hours he had a bid for us that was reasonably priced and started the job two days later. Now two weeks after we first heard of John I am looking at a complete and beautiful job. J. B.’s General Engineering worked tirelessly. They were respectful of our property, had good ideas when questions arose and cleaned up their jobsite each day before leaving. Thank you J.B.’s General Engineering for all your hard work and a job well done. If you ever need any concrete work done, I highly recommend this seasoned professional.


I desperately needed some work done on my property but after receiving a few referrals from friends, I found that most contractors I spoke with were too busy or did not get my vision. I then decided that I needed to look up contractors using the Internet. Luckily, I found JB’s General Engineering and gave you a call. You were quick in your response to my phone call and came to give me a quote almost immediately. After speaking with you, I got a sense that you understood my vision and were open to accomplishing just that. You were also able to offer your expert advice, which was much appreciated.

The job was started the following day and you and your crew were vigilant in taking care of my needs. I found your crew to be hard working, courteous, knowledgeable of the job and skilled in the use of equipment. I was impressed with the job that was done and was grateful for your patience and understanding when I asked for add-ons.

At completion of the project, I am a “Happy Camper!” I found immense satisfaction in that JB’s Engineering is a “do it all” company. The work included: property grading; delivery and installation of several tons of decomposed granite; installation of electrical conduit; and extensive plumbing to include four faucets. What a relief to accomplish so much at one time.

Thank you for your kindness, understanding, and a job well done. I would recommend your company to my friends and family without any hesitation or reservation.

Bill, Atascadero

The latest storm created a mini Grand Canyon on a hillside in my back yard. Sand and dirt poured/washed onto my back lawn. Run off from my neighbor’s property and more heavy rain predictions created an emergency. One call to JBs General Engineering solved the problem. John came out the same day, assessed the situation and developed a plan to deal with several issues. He prepared a VERY reasonable bid and work began right away. He and his crew completed all the work, including a few extras, in very short order. He even worked with my neighbor and they came up with a solution to prevent runoff in the future. Remarkable to me was his reasonable bid, his experience to identify potential unseen problems, speed of job completion and, he and his crew stayed on the job until it was done right. There were several heavy rains since he completed the job and there are NO problems. If you need a “local” contractor to do any job, JBs Engineering is the place to go. John, thank you!

Shane, Atascadero

John and his crew have successfully completed several projects for me, from full civil and concrete package for a new residence, to miscellaneous grading and additional concrete driveway and patio. JB’s pricing is competitive, service is prompt, the quality is excellent, and the crew is a pleasure to have working around our home. We have referred JB’s to several friends and will continue to work with John and his crew on future projects.

Jim & Katty

I wanted to say thank you for the excellent job you have done on the various jobs you’ve done for Jim and I over the years. We both appreciate that you’ve done great work and you’ve always stood behind your work. In addition, your prices are fair. Thanks for the latest work on our driveway!

12 years of service

Over the past 12 years we have had JB’s General Engineering Company do five jobs for us, including a concrete driveway, concrete walkway, a DG pathway, and dirt hauling to level our batting cage and install a level DG pad for the pitching machine and batter’s box.

We couldn’t be happier with the quality of work done by this company, the work ethic of the owners, John & Crysty Brunz and all their workers, and their professionalism. They met with us first to determine what job we’d like to have done, and also provided many suggestions that we hadn’t thought of to make our job better and accomplish our goals in a manner that was even better than our original ideas.

This company keeps their word on what they say they’ll do and when they say they’ll do it.

One of the things that is most impressive about this company and their employees is they don’t consider their job finished until they have cleaned up the job site so that you can’t tell they have been there. For example, for the most recent job they completed for us (i.e., a concrete pathway) in 2022, they not only cleaned up the job site itself, but even power-washed our driveway to remove the dirty tire tracks left by the cement mixer truck and their work trucks! I’ve never had any other company clean up after themselves like they did. They spent an entire half day cleaning up after our most recent job.

My wife and I highly recommend this company!!

Ken, Atascadero

I recently had the pleasure of hiring JB Engineering for a septic tank replacement project, and I must say that I am extremely satisfied with their services. They completed the job in record time and showcased a high level of professionalism throughout the process.

One of the standout aspects of my experience with JB Engineering was their exceptional communication skills. From the initial consultation to the completion of the project, they kept me well-informed at every stage. John took the time to explain the entire process, answered all my questions, and ensured that I had a clear understanding of what was happening.

The team from JB Engineering demonstrated great expertise and efficiency in replacing my septic tank. They arrived on time, had all the necessary equipment, and worked diligently to complete the project promptly. The quality of their workmanship was top-notch, and I had no issues or concerns with the installation.

Moreover, the entire team was courteous, respectful, and easy to work with. They were attentive to my needs and preferences, and they took the time to address any additional concerns I had. I truly appreciated their friendly and professional approach, which made the entire experience stress-free and enjoyable.

Overall, I highly recommend JB Engineering for septic tank services or other engineering projects. Their ability to complete the replacement in record time, coupled with their excellent communication skills and professional demeanor, sets them apart from the rest. I would not hesitate to hire them again for any future septic-related needs.

Rob & Renee, Atascadero

My wife Renee and I just had JB’s General Engineering remove and replace our half asphalt and half concrete broken up driveway with a new all concrete driveway and approach.

The owner Mr. John Brunz was very prompt in getting us an estimate (which was appropriate) and getting the job started even though they were very busy with other work at the time.

His son Jarrett is one of the hardest workers I’ve ever been around and his crew Justin and Conner followed his lead; once they hit the job site they worked hard until the end of the day and until the job was completed.

Their work was excellent and very professional, and I will recommend them to all my friends and family.

Thank you, John and Jarrett.
