  I had a fantastic experience with CASI! I called them in need of urgent work and Drew came to my site in a few hours and was extremely helpful and able to get ~2200 square feet paved bright and early the next morning with no issues. It was all extremely smooth and fast and Drew and Jesus and CASI solved my problem immediately. Lifesavers!! Would love to work with them again

  Everyone we've worked with in their asphalt department was polite and pleasant to deal with. Everyone in their crushing yard has a major attitude. We brought this issue to the president of the company with no response so unfortunately we decided to stop doing business with CASI until their management starts to address the poor customer service.

  Mr. Mohatt and his team at CASI are extremely, professional and knowledgeable about Asphalt and Asphalt repairs. We had several pot holes coming into the driveways and they cleaned those up in a matter of 30 minutes. SUPER NICE now!!! The Product they used was EZ Street Asphalt mix. Very nice product. Thanks again for a quality job done

  CASI did amazing work and were very professional the whole time they were on sight. I would love to work with them again with any asphalt or concrete job that comes up!

  DO NOT DO BUSINESS WITH THIS COMPANY! I have had my driveway, which is under warranty for a year, with them since September, nothing but issues since. They are not registered with BBB however there is now a complaint there for them. The owner is rude and they think they go 'out of their way' to help you by fixing their crappy job (that's the caulking you see in photos), but they don't fix anything, I have cracks all over my driveway. I paid almost $9k for something that will need to be redone. DO NOT USE THEM. I've posted photos, of a less than 1 year old driveway. Find a legit company if you want good work done.
