Client Testimonials

“Lance, thank you for our beautiful new back and side yards. We're so excited to start planting, watering, and placing furniture out there. We are especially excited about not having a water problem.”

“Thank you for all your time, effort, energy, and attention to detail.”

"We chose Alameda Engineering to build an engineered retaining wall at our home. After speaking with reps from some of the large, big-name local companies, we decided to go with a smaller business that was responsive to all our inquiries and provided personalized service. Alameda Engineering did not disappoint. Owner Lance Capilla was involved in all aspects of the project from start to finish. He handled the permit and inspections. He provided referrals to civil and geotechnical engineering for the wall design. He had professionals at the ready for crane work and heavy equipment operators. Best of all, he personally was on-site at our project each and every day to provide oversight as well as to work alongside the crew when necessary. We were pleasantly surprised to have had direct daily access to the owner for any questions that came up. We were very impressed with Lance and his crew. Same guys every day and everyone speaks English so easy communication. Daily clean up was performed and job site was kept tidy. Lance has a very kind and patient demeanor and is willing to take the time to answer questions and explain the technical aspects of the project. Work was performed on consecutive weekdays until the project was completed. There were no gaps due to scheduling issues. The crew even worked during an entire week of a heat wave with 105-108 degree temperatures! Pricing was fair and competitive. All went smoothly and thanks to Lance and his meticulous planning our proposal was spot on without surprises or extra costs. Support a small business and hire Alameda Engineering. You’ll be glad you did".

I want to give a shout-out to Alameda Engineering. They did a great job in installing a subsurface sump pump and underground drainage pipe to the uphill street. I subsequently hired another contractor to install a french drain, which was connected to the sump pump vault. That contractor allowed concrete slurry to enter the vault (which messed up the vault area and interfered with the drainage system), which I later discovered. Lance with Alameda Engineering came out, and at no cost, fixed my issue. This is above and beyond service. I highly recommend him, both for his quality of work and his caring character.

Our experience with Alameda Engineering was first-rate from the outset. As the owner, Lance took a hands-on approach, making sure we understood each step and the rationale behind every decision of our retaining wall and fence project. His practical advice helped us tailor the project to our needs, considering structure, budget, and timing.

The team was efficient, professional, and quick without skimping on quality. They know their stuff, paying close attention to detail to ensure everything was done right the first time. Being based in Castro Valley and well-acquainted with the local area added an extra layer of trust and convenience.

What really made Alameda Engineering stand out was their exceptional customer service. The team was always respectful of our property, maintaining a clean and organized work site, as well a safe one for our family. They were incredibly easy to talk to, always ready to address our concerns or questions.

I highly recommend Alameda Engineering if you're looking for reliable, skilled, and thoughtful professionals in Castro Valley. They truly go above and beyond to deliver a great experience.

We had water intrusion in our basement after the October 2021 deluge. Two other contractors suggested a sump pump, French drains, and/or sealants at great expense and major property disturbance. Lance suggested a simple pipe to drain water away from the foundation. His solution was tested by the recent deluge: our basement is dry! Lance clearly seeks to solve the problem in the least costly way, unlike many other contractors out there. Thanks Lance! Your fix may not be as easy as ours, but with Lance you'll know your contractor is solving the problem in the most efficient way possible.

We needed a new retaining wall after our old one washed out in a rainstorm. Lance from Alameda Engineering came out soon after we called and made suggestions to prevent further damage before a new wall could be constructed. He installed a new wall that looks like it will last forever. When work started the crew from Alameda Engineering worked quickly without stopping until the project was completed. Our new wall looks great and everyone who has seen it agrees that Alameda Engineering did a great job. Five Stars!!

Lance is the best - period. Called Alameda Engineering after my entire downstairs flooded after the he New Years Eve rain. Lance picked up my call and even though he was over booked he came by the house and not only walked throughout the property to asses the damage - he helped me come up with a temporary solution to keep the rain water out of my house until the issue could be fixed. We ended up hiring Lance and his team and they did an amazing job. Walked us through every step of the way as his team put in new drainage on both sides of my house. If you even think you need updated drainage or if you have a drainage emergency like I did - Lance is 100% the guy to hire.

I've been shopping around for a retaining wall for my house for over 5 years, most companies either quoted me ridiculous prices or not even sent the estimate at all! Lance and he's crew literally saved my house! Price was very reasonable and quality of work was exceptional! It was truly a pleasure to see these guys are capable of! They sure don't make them like this anymore- very strong work ethic!
Thanks you Lance for an amazing work!
