Concrete Contractor reviews across the US

Had Gio and his crew build a sloped concrete slab in my backyard as the foundation for a new deck. They did an excellent job and it was a pleasure working with Gio from getting the estimate to all the way thru the build.
Would definitely recommend them for any concrete type work!

Ultra quickly and efficiently repaired our sidewalk.

Del and his crew did a foundation and concrete work at my home and it came out better than I ever imagined! 5 stars!!

These guys are always on top of their work! Always an excellent job

Professional, reasonable and or competitive pricing, great workers and completed on time.

They did great work in a timely manner. They were professional and I was very happy with the result.

Very sloppy. Many inexperienced workers left alone with little support. Buyer beware. Owner, Delfino Alvarado, GC, is never around at job site and always makes excuses for the poor work quality his company puts out. Check with the CSLB for customer complaints and license currency. Never again.👎🏼👎🏼👎🏼👎🏼

They came in with a good bid and did the job fast and efficiently all in one day. They had the right equipment and staff to knock out the job and do it right.

the team did an incredible job for my project, all the crew members were hardworking people , fast and professional highly recommend ! Thank you

Julian Came out and replace NTR sidewalk repair in San Francisco, Took care of everything including permits. For a great price

Del and his guys did a great job with our driveway and curb in San Francisco. They were on time and finished the work sooner than expected.

Worked with Giovanni to develop a plan and contract for the installation of a stamped concrete patio. Installation was started and finished on schedule. We have a beautiful patio surface that we enjoy and often receive positive comments from guests. A 10+ experience with Ultra Construction.

Ultra Construction did a great job on my concrete driveway in South San Francisco. The crew was professional, on time, and delivered a smooth, durable finish at a fair price. Highly recommend them for any concrete work.

Ultra did an excellent job repaving my damaged driveway. I discussed and negotiated the project with Giovanni. He and his crew were professional and timely in starting and completing the project. I recommend you consider Ultra and Giovanni for your next repaving project.

Was looking for someone to re-do my driveway as it was time for a new look. I was interested in a specific design and color combination. Ultra and the crew were a 10/10 from beginning to start. They gave me multiple different options and ideas. They never made me felt rushed or pressured to make a decision I was not ready to make. Definitely recommend Ultra to anyone wether it be a driveway, concrete, foundation, or any other type of service Ultra offers. 10/10 Highly Recommend.

Ultra did an outstanding job installing and stamping a new backyard patio slab. Their communication with us, resolution of small issues, and quality of work was exemplary. Their construction crew worked in sync to get the job done in a first-rate and timely manner. We’re very happy with our new patio.

Julian and his crews did awesome job finishing my driveway that was abandoned for more than a month by previous contractor. You can tell how professionals and experts they are because the project was completed with quality and for around 5 hours only. Neighbors, friends and my family are very happy of the results. Thank you Julian and crews for giving our family and neighborhood the peace of mind. Thank you Ultra Construction. Keep it up!

Great service and quality work at a good price! Ultra Construction did all the excavation work for my PGE panel upgrade with over 100 feet of trenching. They coordinated with the PGE inspector and my electrician to get the job done in time & budget. They even fixed my neighbor's sprinkler system that wasn't their fault, free of charge. The owner and employees are hard working people, whom I saw several times on Saturdays and Sundays. Will recommend them to anyone needing similar services!

Great job! Giovanni reach out to me quickly after submitting an online quote form. He was thorough looking over the City plans for our business. I was especially impressed when he found required items on the plans that other companies failed to add on the proposals. Any items missing from the punch-list would have cost us money, time, and headaches. Good communication as he kept in touch with us throughout the whole process. Thank you, Giovanni! Anna D.

I want to thank this team; they were very efficient, it was very easy, communication was excellent, they had no problems with the city, and the work turned out spectacular. I recommend them for any job; they are very responsible. Thank you very much ultra Constrution

Giovanni, Delfino, Julian, and the rest of their dedicated crew (including the cement truck operator) did a thorough, highly organized job at replacing and enlarging a concrete driveway and walkway at our home. Giovanni was very professional in estimating the work, going over the contract, and then arriving with the crew to demo and pour it. I am into professional, small details, and the vehicles they utilized all matched and were clean and modern. They even wore uniforms. They were not the least expensive of the bids, but were by far the most professional. Made us feel like we made the right choice which is important with jobs of this magnitude. We used a dark black graphite color for the concrete and as it cures it changes colors and can look a little weird, but I'm sure it will look perfect when done curing. They are also hired to seal it when it does cure. Highly recommended.
