"This is our fourth time using Diaz for our home renovations. He refinished and stained floors and painted several rooms. He also rebuilt an upstairs deck. In addition, he took care of about 10 other little things that needed fixing. As always, Diaz was the best contractor we’ve ever encountered. He came right out for a free estimate. He gave us constructive advice on the proposed work. His crew got started right away - they were reliable, on time, courteous, and cleaned up impeccably each day. Diaz stuck to his estimate. In addition to all these positive traits, one of the best things is that Diaz and his team can literally take care of anything. You will not have to rely on a subcontractor or having to call somebody else - he does painting, flooring, kitchens, doors/windows, drywall work, tiling, bathrooms, etc. He even has his own tree guy and electrician for when those things come up. He doesn’t just do everything, but everything is done to perfection. Highly recommended!"

"This was the second time we hired ROI Construction LLC to work on our home and they did an excellent job both times. Originally our roof was replaced and ROI did a fantastic job, going above and beyond in making sure every detail was perfect. Recently we had the roof and skylights of an addition replaced. In both instances ROI charged less than the competitors and the workmanship was high grade. I highly recommend this company."
