Alex had his guys out to replace my concrete driveway in no time, and got the entire project done…read morein less than a day, with high quality materials. Alex is one of the most professional contractors I've ever worked with -- very kind and courteous, prices work fairly, and is willing to negotiate if push comes to shove. During the install, his team accidentally screwed up a couple sprinklers that are right next to the driveway, but once I let Alex know, he and another employee came out and fixed it right away, free of charge. They do irrigation too, so it was an easy decision. A few weeks later, I had him come out and apply a clear seal to the driveway to prep for winter. The entire process was painless and it looks great! Hopefully this will hold up for many years and winters to come! Thanks for everything, and looking forward to working with you again.

I hired YLN Construction LLC (owner: Edgar Anaya) to replace my front porch and steps. He admitted…read morethe finished job was poor quality and promised to redo it. That never happened. He has ignored all of my calls, texts, and emails despite many attempts to work with him. I work in the building supply business and even referred him to a client, who gave him a patio job and was ready to give him a much larger slab fora new building job. Unfortunately, my trust in Edgar was broken. The concrete is separating from the porch and looks terrible. He admitted it "flashed" because it was poured late in the day in extreme heat. Beware -- he said the work was bad, he offered to replace it and I agreed. He talks about being "a man of his word," and "I would never put my name and reputation this but my experience was the opposite.

I hired this company to install a new concrete sidewalk in front of my home (completed May 26)…read more Upon returning from vacation, I discovered that my irrigation system -- directly adjacent to the new sidewalk -- had a punctured pipe and a missing sprinkler head. A certified irrigation specialist documented in writing that the damage was caused by the sidewalk construction. What troubles me most is not the damage itself -- accidents happen in construction. What is unacceptable is what happened next: I made repeated attempts to contact this company via text, phone, email, and certified mail. I received zero response. Complete silence. I have now filed a formal complaint with the Colorado Attorney General's office. If you are considering hiring this company, please know that once they are paid and the job is done, you may be entirely on your own if anything goes wrong. A contractor's integrity is not measured only by the work they do -- it's measured by how they respond when something goes wrong. This company failed that test completely.

Overall, I would definitely recommend them and would consider using them again for future projects.

My search for a business to do a concrete retaining wall project last year led me to JXB via Yelp…read more I needed to get it moving quickly and Bryan came out right away to take a look and understood everything I wanted to do. He got started on the job quickly and unlike many other crews, he was out here regularly to get it finished without schedule gaps or delays. There were some tricky slopes and existing conditions to coordinate and while I was traveling, we corresponded via text. He'd send photos and I'd respond with sketches to get the details figured out. He's very communicative and collaborative, if you need it, which I do. This year the project was to scrape half the backyard and redo everything. We took down the old fence, removed a big concrete slab, and got rid of all the old sod and walkway. He regraded the entire area with a keen eye towards drainage and matching existing elements. I was looking at pavers but his recommendation for stamped concrete was right on target. I'm a designer and technical guy in large scale commercial architecture. Details more than matter to me and I'm picky. Bryan knows that and worked with me every step of the way so everything I designed was built correctly and accurately. We went to the concrete supply shop and looked at concrete stamps, colors, and finishes so I would be confident in satisfying my picky taste. I really like the finished surface. It turned out so good. He knows what he's doing and is very good at it. Since I'm inquisitive, he explained everything I wanted to know about the process and execution. He got the new, uniquely designed property line fence built with minimal infringement on my neighbors side, taking care of the garden on their side, and kept the overall aesthetic and alignments in mind throughout the build. His preparation with the concrete form work and matching existing conditions is well thought out. The concrete pour was on time and was amazing to watch. Very professional and moved like a fine tuned clock. I don't like projects with hurdles and headaches. This project was fun all the way through. No hurdles, no headaches. Once again, the schedule flowed and he was on-site reliably to get it done. Bryan and the crew are excellent. Don't just consider JXB, move forward with confidence and hire them.
