Trusted Concrete Contractor in Firestone, CO, Serving Boulder County

Ricardo and his crew did a fantastic job and we are totally happy with the results. We felt the project was well worth the investment. From the very beginning thru the end Ricardo was responsive and availed himself to meet with us many times to brainstorm and answer our questions. The whole crew under Ricardo’s direction worked hard and efficiently with great camaraderie getting the driveway, the retaining wall, landscaping and backyard patio done in a few days. They also did a thorough cleaning at the end. We were lucky to have found a company which was responsible for all the different aspects of our project and got it all done at the same time at a highly professional level and for a fair price. We highly recommend Ricardo and the Black Widow Concrete team. We plan to hire them again for future projects.

Ricardo and his crew did a phenomenal job doing our sidewalk. We couldn’t be happier! They were very professional and always on time and delivered on everything that they promised. We’ll be using them again for other projects in the future.

Ricardo at Black Widow did a great job and was very professional to work with. Our job was about 800 sq. ft total with different pads, steps, walkways, and other obstacles.
He was very communicative throughout the entire process. Scheduling was fast & easy. The timeline was accurate and Ricardo was very punctual each day. His rates were reasonable and competitive against other quotes.
During the planning process, Ricardo had helpful suggestions on how to frame around tricky spots and change components in our original design to make the landscaping flow better once done. Ricardo was very respectful and gave specific reasons why we should/shouldn’t do something but always gave us the final say.
During the framing/pouring, he gave us every opportunity throughout the day to ask questions, inspect the work so far, and talk us through next steps so we felt comfortable with the work at each phase.
It’s been a month and it look great and I have had 0 complaints. I will definitely use Ricardo again.

All workers were polite and focused on the job. Ricardo is very knowledgeable and friendly. Came by a couple of times to make sure everything was good. Very happy with my driveway.

Ricardo and his team were great start to finish. The job was 17 x 40 driveway, 4x 27 walk and a 9 x 5 pad. Day 1 demo, haul away and prep 11 hrs. Day 2 pour and cleanup 7 hrs. All done outstanding. Couldn’t recommend anyone higher. They were true to the plan and communicated every step

Ricardo from Black Widow Concrete was kind and professional at evaluating the sealing of the driveway, first and then actually working on it for about 4 hours. He did a good job and I like how it turned out. I recommend this company.

The team at Black Widow Concrete showed exceptional professionalism and expertise in the completion of my concrete project. Very easily understood my design needs and provided excellent guidance through all steps of the process. Highly recommend.
