I’ve worked with A1 Master Pro Construction twice now, and both times the experience has been very good. Oscar responded quickly when I reached out and came the same day to give an estimate. What started as a step repair turned into gutter tightening/cleaning and some roof shingle repairs as well, and he offered a fair price for everything.
The team showed up on time, worked steadily, and handled the job professionally from start to finish. They repaired my step, cleaned and secured the gutters, and reattached several shingles on my older roof. They worked efficiently, the results look good, and they cleaned up when they were done.
This is my second time hiring them, and they’ve been consistent both times. I’m happy with the work and would definitely consider them again for future projects. I appreciate their reliability and the quality of their service.

Oscar and his crew were great. They did an excellent job on my front and side steps. They were punctual and the job only took one week to complete. I already have them booked for the next project.

I needed to hire a reliable contractor to repair and complete my front concrete steps, which had been incorrectly measured by a previous contractor. Some of the step heights were off by more than an inch, and the landing was tilted toward the house. Fortunately, the foundational work was still usable. The new contractor did an excellent job correcting the issues, and the finished result brought real peace of mind. I’m very satisfied with the work and would definitely rehire in the future.

Oscar and his team did an excellent job to repair our old chimney at a very fair price! They replaced all broken and missing parts and even brought the new siding to wrap the chimney like we had before. Can’t expect more than what they did! We will definitely hire Oscar again for any future projects.
