Room Additions and Crawl Space to Basement Conversion in Cook County

What our customers have to say about our work.


“I loved the neighborhood I lived in, but simply needed more space to stay there. Our options were to add on, add up, or add under. After assessing all possibilities, turning our crawlspace into a basement was the best option- the property tax consequences were minimal, and compared to the other options the total cost was much less. Aside from a day or two of rain at the outset, the project run by JD Concrete was seamless. They kept to their schedule, worked professionally, and delivered on all promises for the nal product.”

“We have known Jim Dahlborn for years, and have known that the success of his business was based on customer service, quality work, and homeowner satisfaction. When it came time to replace our driveway and sidewalks, we called JD Concrete. True to their word, the project was completed on time, on budget, and with our full approval. It was a pleasure to work with Jim and his crew.”
