Concrete Driveway & Floor Contractors in Northglenn, CO

"These guys are perfectionists and it shows in their work. I hired them to pour and finish a concrete drive, stairs, part of a drive and Iâ m glad I had them do it. They were very meticulous and installed rebar and electrical conduit within the walk I hadnâ t thought to ask for. I will be requesting them in the future and would recommend them to friends and family."

"Great Company to work with. Gave us a price we could work with replacing our 3 car driveway.. First rate materials, great cleanup and Always kept their word, they were on time, took only the number of days they said they would. They were professional and very friendly. I would highly recommend using them and I plan to do so again soon.! Clover and his team are great to work with."

"So happy we found High Altitude Flatwork. Isaac Luna s a hard working young man building his business the right way. Quality work at a fair price. Communication was timely and the price was the lowest of four bids. Work was done quickly and professionally and finished in three days. We are enjoying our walkways and the new patio has become the family gathering place. I canâ t recommend High Altitude Flatwork highly enough!"

"Ignacio asked to bring his truck onto the driveway which I thought was a huge courtesy. He was prompt to bid. Fast to schedule after I accepted the bid. Professional with a 30 minute call ahead and finished in an hour with a single break clearing cinder block, paver stones and mattresses. He will be called again when needed."

"Rep was on time. Very personable and completed the job sooner than origin schedule install date"

"Eli and his brother explained how they would perform every step of our project and submitted an immediate estimate. They sought our input and approval all throughout, and finished the project to specification and on time. Can't say enough good things about Eli and his crew. They completed the project for two-thirds the price of the next cheapest bid, while doing extra work that the others refused to do. And they do not require any payment until the job is done. We are already discussing our next concrete project. We highly recommend these guys!"

"I'm very happy with the job."

"Carl was great and was able to help out on my project quickly. Great experience!"

"From start to finish this process was professional! JNS is a family business and they took great pride in their work. We had a driveway replaced. We were not expecting concrete to look so nice! Our neighbors were so impressed that they hired JNS to complete an extended patio in their backyard. We plan on having a stamped patio poured at a later date and we would not consider any other company for our next job!"
