"We've partnered with Jimmy and the Orr Constructions & Basement Systems team on several projects, and they consistently deliver great work. They've repaired our front steps, relocated a shed in our backyard, and most recently completed a deck extension for us — which turned out beautifully. Highly recommend them for any home improvement project, inside or outside the house!"

"Vincent did an absolutely beautiful job on my cement and asphalt driveway. Their craftsmanship was top-notch. They finished the job quickly, and left the work area clean when they were not there. They stayed in touch throughout the process, and they take tremendous pride in their work. I have worked with hundreds of contractors over the years and these folks are among the very best and most reliable. Cannot say enough good things, also the prices were competitive, and they delivered a better quality of work than I would expect for a similar price."
