    I don't write many reviews anymore, and honestly, I haven't had many contractor experiences that…read morewould motivate me to change that. But Lassiter Excavation was so good that I couldn't continue to be lazy.  For context, I was replacing an old 35,000-gallon swimming pool with a skinnier lap pool. Lassiter started by completely removing the massive 1975 pool, including every scrap of concrete and piping.  Then they backfilled and compacted. Working to my soils engineer's specifications, they imported and compacted 18 truckloads of quarry fines in carefully controlled 8-inch lifts through the full 12-foot depth of the deep end, all the way to finished grade. They used multiple pieces of equipment, including jumping jacks, a Bobcat, and a vibratory sheepsfoot roller (which I had to look up), and they coordinated compaction testing throughout the process.  When they were done, it looked like a pool had never been there. The site was fully prepared for the new excavation, which Lassiter then completed flawlessly.  I measured their forms with a laser level and laser tape measure, and length, width, diagonals, position and elevations were all within 1/8 inch. That's impressive considering the new lap pool is nearly 60 feet long. When they were finished digging, the walls and floor were razor straight and right on their marks. The crews were outstanding -- friendly, hardworking, detail-oriented, and consistently professional. They maintained an exceptionally clean jobsite throughout the project and even helped me reclaim some old redwood decking.  Special thanks to Santana, Ricardo, Daniel, Jose and team for answering all my questions and caring so much about the end result. If you're considering any excavation work, I highly recommend reaching out to Lassiter Excavation and talking with Bob. They exceeded my expectations in every respect.

    Pat LaTray has teamed with a general contractor he's worked with as a sub-contractor in Marin Cunty…read morefor multiple construction projects that require hillside excavation, grading and trucking off-haul. In 2020 for my new Marin home in Fairfax, Pat used his 40+ years experience to excavate over 1,400 cubic yards for the home's concrete foundation. Wall cuts of over 22-feet high. He also drilled the hillside for over forty 12-foot tie-backs for the engineered hillside retention safety system. Pat's a resourceful, reliable team player, knowledgeable, and on-time with fair pricing. See photos of the project's excavation. The best there is. Highly recommended.

    Mr. La Tray of La Tray Engineering Construction Company came highly recommended to us by our soils…read moreEngineer of record for our home in Marin County in early February of 2023. We have over 3 acres that we required slope repair, extensive grading and trenching, rip rap, along with trenching and drilling for a190 lineal foot retaining wall. We also were required to install a 1K foot long fire line for a fire hydrant on our property. La Tray Engineering Construction passed ALL inspections by all county and private inspection agencies working for the County the first time every time. We were amazed at Mr. La Tray's coordination skills with these agencies and how smooth the inspection processes went without any disruption of work schedules. I will hire La Tray Engineering Construction again without a doubt and have recommended this company to my friends in Sleepy Hollow and Kentfield who have also used him for similar work and were very happy with his performance and proffessional approach to work. His years of Experience and unfailing integrity are everything. Mrs. Kathleen Y. Marin County property owner.
