The contractor was professional, showed up on time, and completed the work quickly. The patched areas look clean and well-blended. Would recommend for basic wall repairs and patch jobs

Carlos fixed a rotten floor joist problem in two days that I was struggling with for a month! Great guy who explained what he was going to do and then got it done. We will be going back to him for bigger projects.
