From our very first inquiry, Justo has been incredibly responsive and reliable. He's clearly a busy man, but he makes the time and actually shows up. If you've dealt with contractors before, you know how rare that is. He follows through and does exactly what he says he's going to do. He stands confidently behind his work, which immediately gave us peace of mind. I'm very particular. It's simply in my nature. I ask detailed questions, I research everything, and I pay attention to the smallest things. Justo has been nothing but accommodating every step of the way. He answered every question thoroughly, never rushed the process, and never made us feel like we were asking too much. His knowledge and professionalism genuinely stood out, and you can tell he takes pride in delivering quality work. We initially reached out because we had a leak in our garage and needed our roof repaired and had contacted several other companies. What really set Justo apart was the balance. His pricing is fair and reasonable, yet you can clearly see the confidence he has in his craftsmanship. There's no pressure or gimmicks, just honesty and solid work. One quick tip: the phone number listed on Yelp is a Yelp-generated number. If you want to connect quickly, use the "Request Consultation" option on Yelp or visit their website for their direct contact information. Give Justo a chance to earn your business. We genuinely feel lucky to have found him, and we won't be going anywhere else. Thank you Justo and team! :)
