What Our Clients Say

Antonio Greco

We hired Lenny from DEMCON to repave the parking lot for our business, and we are impressed with him and his team. The new asphalt surface looks fantastic and has significantly improved the appearance of our property. Not only did they complete the job ahead of schedule, but they also ensured minimal disruption to our operations. We highly recommend this paving company. We have another location we are getting a quote for concrete walkways.
Justin Jin

As homeowners with specific tastes, my partner and I conducted extensive research before selecting a contractor for our concrete pool deck renovation project. DEMCON Design & Build emerged as the clear choice, and we couldn't be happier with the outcome. From start to the final sealant application, their attention to detail and commitment to quality were evident at every stage. The design phase was collaborative and insightful, with the team offering valuable recommendations based on our preferences and budget. The installation process was executed with precision and efficiency, resulting in a flawless pool deck that exceeds our expectations.
George K.

I had Lenny install 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 needs concrete, asphalt, or interlock construction services.
