Exceptional Service - Professional, Efficient, and Highly Skilled!…read more I cannot recommend Cosmin enough! From the very beginning, he demonstrated a high level of professionalism and expertise. I needed a land survey done quickly for my Adu addition in San Jose, and Cosmin was incredibly responsive to my request. He listened carefully to my needs, provided clear explanations, and delivered results faster than I expected. What stood out most was his attention to detail and willingness to answer all my questions. Cosmin made the entire process seamless and stress-free. If you're looking for a land surveyor who is not only highly skilled but also acts quickly and values customer feedback, look no further. Five stars without a doubt - I'll definitely be using his services again in the future!

He was also able to help me figure out (based upon my project) what I would need for my location and building department. Up until the day of the survey he kept me up to date with his scheduling by the hour, through email and phone call (which I appreciate these days). On site he was efficient with his time and very friendly. I was able to receive the survey within the next few days. Definitely would recommend!

Greg was instrumental in guiding us through a 2 yr, 5 unit condo conversion in San Francisco…read more From start to finish Greg was thorough, communicative, and generally delightful to work with. What sets Greg apart from other professionals is his ability to work within the complexities of our individual building and owner group. No matter the issue we faced, I always felt comfortable contacting Greg with questions and he always came through with thoughtful answers to put my mind at ease. This along with his high quality work made him an invaluable partner throughout the process. Greg is a shining star in a cottage industry full of indifference and incompetence. I could not have done this without Greg!

We had a great experience working with BALS. Keith did a boundary survey of our property. We had…read morereached out to many surveyors in the area and BALS was definitely the most responsive, organized, and thorough in their response. They provided a reasonable quote, and provided a clear estimate of the timeline. The survey markers were placed relatively quickly. Alameda county took some time to record our survey, but once it was reviewed it was approved right away. I called the county for an update at some point and they actually pointed out that our survey was very well done! Sara was also very helpful and responsive to my numerous questions throughout the process. I would highly recommend!

Buyer Beware. It…read morehas been 2 1/2 years since we started the survey process with this company. They have around 5k of our cash money in their hands and they still have not completed the survey and filing with the county. I have been calling and emailing intermittently in good faith, but there's always an excuse as to why the work is not done. One is usually having boundaries marked and surveys done because there's another issue at hand or plan that comes next. I never imagined that we would be this far down the road and unable to start projects because the surveyors cannot complete the job that they have been paid 100% of the fee for. What will inspire them to get going? Legal action? Filing a complaint with the County? Fine, but what a pain. It may be tempting to use the company (BALS) that says they can come out and get started sooner than another company, but in the end, we've waited far, far too long. Their integrity is lacking, to say the least. They have taken advantage of us probably largely due to the Bay Area's insane real estate market and demand for their services being high. No one should have to spend their time chasing down the product they paid for outright as they demanded. I cannot recommend BALS and hope you find your surveyor elsewhere.

I did not know Pedro was to start digging at 8am on 12/13/2025 (Saturday) until PG&E came to mark the gas line around noon on 12/11/2025! Worse yet, my neighbor Pedro encroached on my property when marking the property line by himself! It was somewhat obvious because a few other neighbors noticed things did not look right, and brought the issue to my attention in time! Yet when I talked to Pedro, he brushed me aside and refused to pay for a survey! In a situation like this, Bob from Apex was an answer to my prayer. He was extremely professional, capable, and kind. He came out right away to check the property line w/o being paid, and advised my neighbor Pedro on where the correct property line should be. It turns out Pedro's marks were about 2 feet into my property ! Bob left my neighbor Pedro to mark the property line and the situation is still unresolved. Yet I'd like to thank Bob for his help. He is amazing and my hero!
