Concrete Contractor reviews across the US

G-Cat was amazing! When i first met Vito, he was polite, professional and he really provided great advice. For me that goes a long way during the selection process. The work they did for creating our new backyard patio was fast and high quality. We are really pleased with the new cement patio and have received a lot of compliments even from the other contractors. I would recommend and work with them in the future.

G-CAT was a referral from a neighbor & they were really awesome to work with. I’m very happy with the outcome of my new concrete driveway, garage floor, patio and service door stoop. The office staff communicated effectively & efficiently throughout the process. They were on site on the day and time promised - sometimes earlier/sooner which was great. A few small situations came up during excavation but they explained everything clearly and made recommendations to ensure I was happy with the results and most importantly, there wouldn’t be any issues down the road. They went above and beyond all my expectations and really restored my faith in contractors after experiencing nothing short of a nightmare contractor a few years back.
It’s really awesome to see a local, family owned company that still makes it a point to connect with their clients with the grace and patience that they do. I highly recommend G-CAT for your next project!

It was such a great experience all around. The company helped with colors and patterns which ended up matching beautifully. The crew were so professional. From laying the concrete to cleaning up after. Could not have been happier. Thank you so much we are truly happy and love are new patio and driveway.

We interviewed a number of contractors but G-CAT who was referred to us by a friend was our final choice.

They did a great job removing our asphalt driveway, porch and large cracked concrete patio and replaced it with concrete. We also had a sidewalk added connecting the driveway to the backyard patio.

Vito helped make design recommendations when we asked and the design is perfect. Michael , his father also was part of the team and he helped us understand some of our current village code standards for our safety which we didn't have in our prior porch and steps.

We looked forward to hearing the workers arriving at our house by 615a with large equipment and they worked wonderfully as a hard working team to get the job done.

We love our concrete work and our neighbors keep stopping by admiring it and making alot of positive comments to how it help enhance our home and street appeal.

Thanks G-CAT!

Replacing a driveway with cement is a BIG, expensive job - G-Cat makes it easy. I really appreciate the efficient, professional service and fantastic new look of my home. Curb-appeal is everything in real estate, having G-Cat recreate my drive and front walkway makes me happy every time I return home!

Oney rules lf the road

They need to hire some better people. Guy pulls out of a construction site, and goes the wrong way down a divided road, nearly hits me head on. I swerve around him and jump over the curb, the guy honks the horn and gives me the middle finger. Absolutely ridiculous.

Their team is very productive and professional. They have large capacities on construction sites, yet treat their customers like it is a family-run business! Highly recommend for excavating, concrete and snow removal.

I recently hired Coronet Construction to dig out and underpin my basement, and I couldn’t be happier with the results. From start to finish, the team was professional, efficient, and incredibly knowledgeable.

Sam, the lead sales associate, was a standout—always courteous and well-informed. Anytime an issue came up, he didn’t just bring it to my attention—he came prepared with two solid solutions. That kind of proactive communication made the entire process smooth and stress-free.

Martin, the lead foreman, and his crew handled all the digging and concrete work with precision and care. Their work ethic was impressive, and they kept the site clean and organized throughout the project. You could tell they took pride in their craftsmanship.

If you’re considering a major basement renovation or structural work, I highly recommend Coronet Construction. They deliver quality, transparency, and peace of mind.

Reached out about concrete for expanding a front porch, new stoop and driveway. Responded back quickly and came out to quote us right away. Was the best price form the other quotes we got. Explained the process and helped with getting a permit for it. Would use again for other concrete needs.

Tom was outstanding and helpful. We had a narrow window of time and needed a professional quote. He was able to accommodate our schedule and provide a comprehensive solution. I would definitely recommend his services to others.

Tom and his crew were awesome. We needed our stoop and sidewalk to the driveway replaced. They did a terrific job. It looks fabulous, and they had competitive pricing.

Had Sennstrom install a stamped concrete patio in 2012. It still looks brand new in 2024. I hired them to install a new concrete driveway this year. Great experience both times.

The team at Sennstrom did an incredible job of replacing my concrete driveway. They were professional and would recommend them to anyone. I’m so pleased with their work, would hire them again in a heartbeat! The absolute best people who did the best work.

We had a large front porch stoop (with a roof overhang) replaced by Concrete by Sennstrom. They did an excellent high quality job. Everything from the estimation and communication to the work crew was very professional. They are very experienced with skilled workers who really know what they are doing. We are very happy with the results and would definitely use them again.

Such a great experience working with Jonathan and his team. He was quick to respond, talked through the entire process step-by-step and even visited my home multiple times. We replaced and leveled 6 slabs of sidewalk and part of our driveway. Workers showed up on-time, very professional and did great quality work. Overall, I am very impressed and will definitely use them again. Highly, highly recommend!!!

I hired Sennstrom to replace my driveway that slanted towards the house while also replacing a set of old front entry steps that had sunk into a slant a, turning them 90 degrees and building a walkway adjacent to the driveway to the sidewalk. Once scheduled, the project took about 3 days from tear out to completion. They crew was easy to work with, clear about what they were doing and why. The new driveway is beautiful with the correct grading away from the house. Totally professional workmanship. Could not be happier.

Leaving a review for a relative:

Work completed: Partial garage floor and complete walkway and porch.

Many thanks to Jonathan, Santiago and the entire Sennstrom crew. High quality work done efficiently. The crew was polite, friendly and proudly paid attention to detail. We would highly recommend!

I must say, this company is one of the most professional and attention detail companies I have ever subcontracted. Not only that, Jonathan, the lead foreman and his team were always on time and kept us informed on process. When the job was complete, he also informed us on the curing process and what to expect. We went with a California finish on the driveway and the front walk ways with a pebbled colored stained finish which looks amazing! My driveway, apron, and walkways are absolute flawless. If you want quality, commitment, honesty, experience and to know the job will get done with no headaches, I would highly recommend this 5 star company. Thanks again Jonathan and team for a great experience!!!!!

We had our front stoop, steps and sidewalk replaced by Concrete by Sennstrom in October of 2025.

From the moment I met Jonathan we had a great experience, he was flexible and answered any text promptly. The communication was excellent throughout the project and their foreman, Santiago was knowledgeable, accommodating and professional as was their entire team. They worked fast, but made sure we knew what was being done every step of the way. We are very pleased with the experience as well as the end result.

I would definitely recommend Concrete by Sennstrom. Thank you Jonathan, Santiago and team!

Great work. Patio looks excellent.
