5.0 Douglas T. Aurora, CO

They show up on time and do what they say they will do. The completed work exceeded my expectations.

5.0 Joe R.

Eliseo was on time and professional:

5.0 Maureen K. Westminster, CO

Eli Castonon and his crew were wonderful., very professional and experienced. They al worked very hard and did an awesome job. I really appreciated Eliâ s expertise and strong customer service. They replaced the front sidewalk and the carport floor plus a section of the driveway with great attention and care.

5.0 Amy V. Westminster, CO

I am absolutely delighted with the quality of work, professionalism, integrity, communication and value. This was a major project on a mid-century modern home, needing demo of old driveway and carport, re-grading, concrete pouring and finishing. Eli was a pleasure to work with and his team was great. They also kept the site pretty clean, given all that was happening, and my neighbors really appreciated that. I had a structural engineer involved in the project and Eli worked so well with the engineer. Big corporate folks can become difficult when an expert is hired to oversee and consult on the project, but Eli was great. He viewed the engineer as even more to ensure the work would be done without issue, and that was certainly the case. My driveway and carport are gorgeous! What a find Eli and his company are. I would hire them again in a heartbeat. Eli, thank you!

4.5 Ralph M. Aurora, CO

Eli is very professional and accomodatig. He understood what I wanted and was able to make suggestions to improve on my project.

5.0 Steve P. Englewood, CO

He did everything that I wanted and also replaced the gutter drains at the ground level with pipe that went under the sidewalks so that they all drained under the sidewalks into the lawn. He even added (after his quote) a small square pad on the inside of our back fence so that we had a place to put our two trash cans. And with the new sidewalk, it makes it easier to haul the trash cans out to the street, and now it is easier to move the lawnmower into the back instead of hauling it over rock. He also replaced the steps going up to the porch and made the steps to not only go down to the sidewalk to the front, but he also added steps off to the side to go to the back yard. He did the job in just two days and the crew cleaned everything up nicely. Very friendly crew. I would highly recommend them for any concrete work that you may need.

5.0 Ed H. Broomfield, CO

Eli and his crew did excellent work replacing and pouring a new 3-car driveway and portions of two sidewalks at our home. At our request, Castanon Concrete replaced a 4-inch driveway slab (with nonstructural concrete) with a 6-inch pour using structural concrete. Our old driveway was poorly prepared, causing the old, non-compacted subsoil to be very muddy. Eli removed more soil, added more than the expected amount of road base, laid a grid using a ½ inch rebar, and also tied it into the foundation. They invested significant time to properly compact the subsoil and road base before the new pour. One portion of the sidewalk needed special care and skill to replace. The old walk was pitched incorrectly, and it also was located about 1 inch away from our A/C unit. The crew was especially careful to not disturb the A/C during removal and create a new pitch to drain moisture away from our foundation. At our request, the crew did an exceptional job with clean-up. The muddy worksite was a challenge. Eli and his crew power-washed the entire area (curbs, gutters, sidewalk, and a significant portion of the street). And to finish up, the crew invested a lot of time picking up even small debris, and they reinstalled the 1 ½ inch crushed granite rock bordering our new driveway. Eli said his goal was to install a new, high-quality driveway without people even knowing it was a construction zone hours earlier. Castanon Concrete did precisely that. I highly recommend Eli and Castanon Concrete; they went out of their way to meet and surpass our needs.

5.0 Dilip C. Aurora, CO

Smooth execution by this company. Very professional, easy to deal with people. Everything was done as expected. We hired them to do another project after they installed a new 3-car driveway for us. Highly recommend this company.

5.0 Elizabeth G. Aurora, CO

I had a pool pad installed in my backyard. They arrived on time and did quality work. They charged exactly what I was quoted. I would definitely hire them again.

5.0 Bob C. Denver, CO

They were professional quick and inexpensive.

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.

  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
