What Our Clients Say


  • Ethan Davis

    I recently had DEMCON Design & Build install a concrete driveway for my home, and I couldn't be happier with the results! From the initial consultation to the final finishing touches, their contractors exhibited professionalism, expertise, and a dedication to quality that truly impressed me. Not only is my new driveway beautifully crafted, but it also perfectly complements the aesthetic of my property. The attention to detail and craftsmanship are evident in every aspect of the project. I highly recommend DEMCON for anyone looking for top-notch concrete driveway services. Thank you for exceeding my expectations!

  • George K.

    I had Lenny installed a concrete walkway for our front yard a few weeks ago, and let me tell you, it's been a game-changer! The process was super straightforward - we had a chat with their contractors, they gave us some great design options, and boom, the next thing we knew, we had a brand-new concrete walkway! These guys are professional and hard-working to a fault. It's not only sturdy and practical but also adds a touch of style to our home's curb appeal. I have no problem recommending his company to anyone that need concrete, asphalt or interlock construction services.

  • David Lehmann

    So, we decided to level up our backyard game with an interlock patio from DEMCON Design & Build, and boy, are we glad we did! From the get-go, these guys were all about making our dreams a reality. We chatted about our ideas over coffee, and they totally got what we were going for. Fast forward to installation day, and let me tell you, their hard-working ethics and professionalism shined through. The contractors were super chill, but man, they knew their stuff! Now, every time we step onto our sleek new patio, it's like stepping into our own little slice of paradise. Huge shoutout to DEMCON for hooking us up with the coolest spot on the block. Thanks guys and we appreciate you very much.
