I highly recommend OT Concrete. They completed concrete work at my home and the quality was excellent from start to finish. They were responsive, fair on pricing, and professional throughout the job. I would absolutely hire them again and recommend them to anyone needing concrete work.
OT Concrete, did a concrete slab, resurface retaining wall and built a lean to shed build. They were friendly, very professional, cleaned up everything after completion. If I had any questions they were quick to respond. We are very pleased with their work. I would highly recommend them for your building project!

OT is great to work with. He provided accurate estimates of the concrete demo and repair. We did have to make changes to the estimates as we discovered additional scope however he was upfront and clear about why that needed to happen. He coordinated regularly with me and HOA to ensure everything was going on track. With him leading, i didn't have to chase him down as he kept to the schedule and did a great job of the concrete demo & repair for 2 garage driveway repairs in our community. I would highly recommend OT for similar jobs.
The entry portion of my driveway needed to be lowered. Cars would hit the concrete upon entering because it was too high. Ongolea did a great job in correcting this problem for me. He has many years of experience and offered ideas to make the project look more complete. He is professional, hard working and fairly priced. My driveway looks great! Thank you Lea
