Concrete Contractor reviews across the US

Alonzo and his crew did an excellent job on repairing my sidewalk and curb. They broke up all the old sidewalk and removed all existing roots and debris and did this all in one day.

Nice fast clean Job at a good price.

My wife shopped the Job and we got a good price and a good job.

5 star review.
Sidewalk looks brand new.

It was a pleasure working with this company. The sidewalk needed repair and they set up a day and completed the job promptly and professionally. The concrete work looks amazing. Pricing was reasonable. We didn’t need to get any other estimates

It was great working with Alonso Romero at Safer Sidewalks. We love the finished product and he helped guide us through the process with the city. Our sidewalk is now safe without trip hazards. We are truly grateful.

Dennis was extremely respectful and considerate. When I asked him if he needed help he said he could get it. He asked if I wanted him to move his car. Offered to help me with things. He explained his process to me along the way. He was very thorough and did a fantastic job!! I highly recommend this company.

If you want precision, responsiveness, and outstanding work for your sidewalk, parkway, curb, or driveway project, Alonso Romero and his team at Safer Sidewalks is the only contractor to call. He is licensed, insured, bonded, knowledgeable, and most importantly, EXTREMELY PROFESSIONAL and POLISHED. I hired Safer Sidewalks to repair a curb, parkway, and sidewalk that was destroyed by a prior unethical contractor. When I first called Safer Sidewalks, I was nervous. I have been in the residential rental rental and property management business for over seven years, and I have had my fair share of horror stories with deceptive, unresponsive, and unethical contractors. Having been jaded by such past experiences, I was not expecting to have such an exceptional experience that I ended up having. What a welcome surprise.
When I called Safer Sidewalks, it felt different. To my surprise, Alonso picked up my call on a weekend morning, when I called him extremely stressed out about the problem that I had with my sidewalk, parkway, and curb that was destroyed. He generously and graciously spent almost an hour on the phone explaining the process to fix my problem. Before the day was over, he sent me a follow up email with a detailed breakdown of the project. He answered more of my phone calls that I made to him for clarification, and that did it for me. Without hesitation, I immediately decided to hire him and met him a few days later to sign the contract to get the project started. He immediately got to work on getting the first city inspection scheduled for this permitted project.
Once the project was underway, I continued to be supremely impressed throughout multiple stages of the project. He immediately set up all requisite city inspections. Alonso regularly sent me updates either by email, text, or phone call. He answered my calls and texts. He sent photos and videos of the progress. He gave me a realistic timeline for the project, and he finished ahead of schedule. He did not do what most contractors do: add on surprise costs along the way because of "undiscovered" costs. The price he quoted me--the price on the contract--was what I paid.
One more note: Alonso has what most contractors do not have: extensive public works experience and regular contact with public works city inspectors and supervisors. He is fully licensed and well insured. He is bonded. He has an active Class B and Class C8 license from the California Contractors State License Board. Many contractors do not have the C8 license, which is a tough license to get for complex concrete work. So if you are shopping around, and you find a contractor that can "do it for less," you are not going to save any money. Most likely, that cheaper contractor will not do it right, and you will have to pay extra down the line to fix those mistakes. As I have learned through extensive experience, you pay for what you get. So if the price you are quoted by Safer Sidewalks is higher than other contractors, THERE IS A REASON. You pay for what you get. Pay it. You will pay for peace of mind and a job done right the first time.
Overall, my experience with Alonso Romero and his team at Safer Sidewalks was exceptional, outstanding, and beyond my expectations. From years of experience with numerous property projects in Los Angeles, Alonso Romero is the absolute best contractor that I have ever worked for.

Alonso Romero from Safer Sidewalks installed twin 6' permitted curb drain pipes under the sidewalk in front of my house and poured a new sidewalk panel above the pipes (curbolet installation). Alonso worked with City of Los Angeles Bureau of Engineering inspectors to ensure all was proper and to code. The pipes are for safely charging electric vehicles on the street, and both Alonso (and BOE) were supportive of this unique request. He worked patiently with me through the design process and provided balanced guidance on the pros/cons of various options I had to choose. Alonso is C8 certified and knew both of my BOE inspectors from previous work, so his knowledge and experience certainly showed. Would definitely recommend!

Martin and his crew worked on my driveway today. After 20 years the void below my driveway started to show. They pumped polly and stopped the driveway from sinking in the future. They did an amazing job and could not be happier. BELLO/GONZALEZ/MATEO! THANK YOU!!!!!

We had a foundation repair and couldn't have been happier. Best bid we received. Crew arrived right on time. Worked their tails off digging by hand in hard dry clay. Performed the work exactly as described. Kept us informed all the way. Gabriel the crew supervisor must have came up the stairs a dozen times checking on the cracks in the walls and the doors that didn't close. Now our doors close and latch. The cracks are nearly gone. Finally, the work area could not have been cleaner. Thanks so much Gabriel, Gerardo, Leo, Cordero Raul, Trujillo, Edition, Cody, and Matt.

From the beginning to the finish the whole team did a great job! Matt meeting me, designing and financing my project. Then Gabriel, Leo, Gerardo, Odilio, Trujillo and Raul showed up and did an amazing and efficient job. It looks great.

As a project manager in the construction industry I can tend to be a little overbearing when it comes to hiring contractors to work on my own home. During the discovery/bid process Cody was extremely knowledgeable and helpful with explaining the issue and the options we had to remedy my problem.
Their bid came in at a fair value and below what I was as expecting so we signed the contract to move forward with the work.
Olshan installed 8 cable lock st piers to lift and stabilize our foundation.
Alejandro was in charge of the actual work on our home and he is an absolute rock star. He was extremely knowledgeable and went above and beyond to ensure that the job was performed correctly. His crew was respectful of our home and got in and out as quickly and cleanly as they could. Alejandro answered all texts and phone calls in a reasonable amount of time and always kept me in the loop. Overall, foundation work is tough but Olshan made it look easy. Cody and Alejandro were exceptional throughout the process and I trust if I ever need anything in the future they will be there for me.

The crew that showed up today had a big job to do...indoors and outdoors on this feels like 107 degrees day! Basement walls were lined and a sump pump was installed to trap and expel water coming in during heavy rains. A beautiful finish! Loads of concrete and dirt cut out and carried out for the trench and then concrete work to complete. On the other end of the house they cut out more concrete and installed a drain to carry water away from the foundation and exterior door. They were friendly and willing to work around a water heater issue and I couldn't be happier!
Thank you to Gabriel Gerardo, the man in charge today, and his hard-working crew, Noe, David M, Antonio H, and Candelario. A fantastic team!
The process was great from the first appointment with Heath Merriman to quote the job, office contacts for scheduling, and most importantly, a well-completed job. Thank you, Olshan Foundation, I highly recommend you!

Great experience. Martin and his crew used their product to fill the void under my concrete front porch and to raise our driveway curb (something new for them). The curb had sunk, the cul-de-sac raised, and the drive collected water. They raised the curbing (long, thin pours) without cracking it! Now to regrade the drive and the water will drain - yeah! Very happy with the outcomes and have more work for them in the future.

We hired professionals from Olshan to replace concrete stairs from our house to an exterior concrete sidewalk. In addition, Olshan replaced the exterior concrete sidewalk. The front office was very professional and responsive. They checked in with us as the scheduled job start-date got closer. The concrete team, led by Jorge Aguirre arrived at our house on time on the scheduled day. They carefully extracted the old concrete steps and sidewalk around the adjacent flower beds and in-ground sprinkler system. They efficiently cleaned up at the end of day one. On day two, Jorge and his team arrived and installed the new concrete stairs and sidewalk. Jorge stayed on-site and supervised his team both days. They carefully smoothed and graded the newly-poured concrete and added feathering for a very professional finish. We would not hesitate to use Olshan and Jorge for any future concrete work. They did a fabulous job and charged exactly what they estimated the work to cost. Jorge even left us several bags of topsoil to grade our flowerbeds between the new sidewalk and garden surface.

I hired Olsham to level up my 38 year old home and I pointed out and marked every single crack and problem to the salesman Chris. My finished basement was noticeably dropping off in places and I emphasized I wanted it fixed.
I am a senior citizen and this was a lot of money. Several deep holes were dug on the outside and “ piers” installed.
I had spent an entire week moving everything out of the finished basement, today I was told by Chris that he never agreed to address the floor problem. I am very unhappy with the way I was treated and I asked the outside crew every single day when was the basement floors going to be addressed. I never got an answer and today I was told nothing could be done about it! Really!! Chris had a week to call me back but never did.
I feel like I got ripped off.

I'm so happy with the service that I received here in Basehor, Ks. My steps and sidewalk have been an eyesore for years and you guys fixed it within a week from my initial phone call to clean up. Robert explained everything to me at our appointment for an estimate for poly jacking and Martin and his crew (Raul, Jose, and Idayoel) did such a good job making my steps look nearly like new and did a bang up job with clean up. Thanks to you all!

Martin, Antonio, Carlos, Gorge, and Alex were great! Finished the concrete lift job quickly, cleaned up and the results are amazing! Thanks! Liberty MO.

Raul’s crew came out the next day and did 6 foundation piers, raised the house 1/2 inch, installed a sump pump, filled a large crack with epoxy, cleaned it all up and were finished in ONE DAY! Great job! Thanks.

We needed smart jacks installed in our crawl space to help with sagging in the center of our house in Clearwater outside of Wichita. Marty came out to do the estimate and quoted us MUCH lower than two other foundation repair companies. Financing was very simple, and Gabriel, Gerardo, Odilio, Leonardo, Trujillo, and Cordero Raul did a fantastic job on the work. Our house feels much more stable and doors open easier. We had a great experience with Olshan.

We hired Olshan for foundation work in December 2023. Since then, our home has developed serious structural problems that began shortly after their work was completed, and the process of getting them addressed has been slow and frustrating.

After the installation, large gaps—about 1 inch—opened between the floors and interior walls in several rooms, including the living room and two bedrooms. Not long after, the front stoop also sank. When Olshan returned in November 2024 to lift the stoop, that repair created another issue: a nearly 4-inch gap between the stoop and the sidewalk below.

Over the last two years, Olshan representatives and management have visited multiple times (January 2024, November 2024, and August 2025). At one point, we were told to water the foundation weekly—1 to 1.5 inches—even though this was never stated as part of the contract. This was done consistently for months, with no improvement.

Because of how concerned we became, we had other independent foundation professionals look at the situation. Several contractors, whose names we are not sharing for privacy, told us the work appears to have been done incorrectly and not in line with proper foundation repair standards.

As of now, the problems still remain:
•The interior structural gaps are still there
•The sidewalk and stoop are still separated
•The underlying foundation issues have not been fixed

This has been stressful, costly, and deeply disappointing. What has made it worse is not just the defective results, but the lack of urgency and accountability after repeated attempts to get this resolved over nearly two years.

We expected lasting stability and professionalism. None have been received.

Olshan-Kansas City completed a concrete leveling project at my home, and I couldn't be happier. The crew arrived exactly when promised, they carefully explained what they were going to do, did the work efficiently, and completely cleaned the work area. It looks SO much better, and I am 100% satisfied. Thanks to Martin Bello, Idaquel Gonzalez, and Gorge Muteo for a job well done!

Thank you to Olshan for leveling my house. My house was aggressively settling and my front door was pinched shut, wall cracks appearing, windows sticking. Olshan's process from start to finish exceeded my expectations. They were the company that had found the root cause of my settling compared to the two other companies I received bids from. Edgar and his crew Yovani, Wilmer, Nery, Edyson, and David did excellent work. They had to work on the outside and inside of my house. There was a area in my basement where they needed more room for digging. I had many storage bins that needed to be moved in order to make that space. The crew jumped right in and carried multiple storage bins up the stairs and out to my garage. I acknowledge they didn't have to do that in their scope of work and I appreciate their help. They did an incredible job cleaning up all the dirt in the basement and outside on the walkway. I highly recommend Olshan!
