“Had a great experience with justo . He gave me a fair estimate for the work, (roof leak) was on time for estimate and the job . And was very detailed in his work. Will definitely call again ! Thank you !”

“Professional licensed construction company. They were prompt both in their initial estimate process and their completion of the job in hand. They worked nonstop to meet their deadline with cleanliness and accuracy in regards to the job that they did. Highly recommended.”

“I highly recommend Diamond Construction. The owner, Justo, immediately responded to my request to have my roof inspected after discovering the paint bubbling in my master bath, during heavy rainfall. Justo came over the next morning (Sunday), discovering two roof leaks. He showed me the photos and thoroughly explained what the process would entail. The following day, I received the estimate for the roof and drywall repair in my bathroom. I was very pleased with the price. Justo wasted no time, repairing the leaks, with a short window before the next rainfall. Justo also repaired the bathroom drywall and painted the wall and ceiling affected, in a timely manner. I was appreciative of Justo’s reliability. promptness, professionalism, kindness and for cleaning up after the job was completed.”

“I'm so glad we found Diamond Construction. After a long search for a trustworthy general contractor and being extremely selective about who we work with, finding Justo truly felt like hitting the jackpot. 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 ”

“Diamond Construction is the diamond in a coal mine of contractors! The owner, Justo Revolorio, is everything you’re looking for in a contractor: honest, reliable, skilled and his prices are very fair. In addition, today I was also very impressed with Justo’s contentiousness. He had quoted putting in a new wall heater but the price of the wall heater had changed since quoting the job last week. As he was about to purchase the heater Justo saw that it was no longer on sale and he called me to verify that I still wanted to do the job. I was very impressed with this thoughtfulness since I had clearly agreed to pay Home Depot’s price for the heater (whatever that was) and then his fee, so it was very kind to double check before moving forward. This is the third or fourth time that Justo has done jobs for me and each time I’ve been equally impressed and happy. Justo is a great find!!”
