"We asked Sam to meet us with very little notice, and he was able to accommodate our schedule. He came on time, inspected the property in question, and two days later we had a very thorough written report which documented his observations , recommendations and conclusions. He also provided a diagram of the suggested repair for the problem area. We were very happy with his services."

"Had the pleasure of working with Miri (project manager) and Zion (owner) for this project, both of whom I highly recommend working with. My project with them was a 800sqft garage conversion ADU, which turned out beautifully as shown in the pictures below. Miri was a very pleasant and responsible PM, very easy to talk to and always on top of scheduling. She would frequently stop by the site to make sure work was going as expected, and would brief me on things such as what work needed to be done next and what needed to be bought. For owners that are doing this for the first time, she is the kind of PM you'd want. I also have the utmost respect for Zion, who was the reason I decided to go with B&B in the first place. He was easygoing, an efficient PM that kept work on track, and overall an extremely dependable individual you'd want to entrust your project to. Working with Miri and Zion felt like working with friends and that's exactly what you want with a construction project spanning months. A heartfelt thank you to both of them and all the workers at Brother & Brother for a job well done on my ADU."

"The Job went perfectly.
 Beau did an impeccable job attaching the conservatory to the main house without any dust or  construction debri entering the home.  He cleaned up every day after work. He kept the exact hours he said he would work. He kept the job on schedule.
He worked with the city on all the permitting and inspections.
The quality of workmanship was well beyond my expectations and became the envy of everyone who saw the finished room.
Beau came in right on bid. NO COST OVER RUNS!

I would highly recommend him for any job from building an entire home to remodeling that garage you have been putting off for a while."

"Mine being a small job I was pleasantly surprised when my first meeting was with Mark Pasquini, owner of the company. He was great and I felt good about his company. Mark assigned my plans to Ashley Hotchkiss who took me through the whole project. I was kept up to date on everything and my questions were answered quickly. I would recommend giving Pasquini Engineering a call whether your project is big or small. Thanks to all."

"John and his crew at Momentum AE were wonderful from start to finish. John helped me design my first residential home and ADU (accessory dwelling unit) in Santa Cruz. His knowledge of architecture and engineering made the design portion of the home a breeze. 

I would recommend Momentum AE to anyone that is looking for an Architect/Engineer/Real Estate Brokerage in Santa Cruz. I can officially say Momentum AE is a one stop shop when it comes to residential or commercial development 

Thanks again John!!!!!"

Structural Engineering questions, answered by experts

A construction manager is particularly useful in the case of a large-scale build with custom design elements, so it’s usually worth it to hire one. They can help manage your budget, maintain quality control, oversee timelines, and navigate unexpected hurdles. While construction managers are pricey, they can actually save money in the long run by identifying cost-saving opportunities and ensuring the project stays within budget.

No, squeaky floors do not always mean there is structural damage. The noise is often caused by friction from issues like loose floorboards, gaps between the subfloor and joists, or loose subflooring. While many squeaks are harmless, persistent or worsening noise could indicate a more severe problem. If you notice other signs of structural damage—such as soft or sagging floors, cracks running from the wall to the ceiling, or horizontal cracks in your foundation—it's best to have a professional inspect your floor to determine the root cause.

The 10 10 rule describes the formula most contractors use to determine how much to charge for a job. Allowing for 10% overhead above the total projected cost to do the work and 10% profit sets a contractor up for success, even if there are delays or other problems on the project. This formula isn’t a hard-and-fast rule, but it is a ballpark figure to begin with when estimating your expenses on a job.

Yes, professionals reinforce the foundation with additional supports or piers to prevent future sinking.

The process involves initial consultation, concept development, detailed planning, regulatory approvals, and integration of contractor work for project execution.
