Why Reystone

Not Your Average Contractor

We built Reystone to be the opposite of every contractor horror story. Here's how the "new school" approach works compared to what most homeowners are used to.

"Old School" Contractor Reystone "New School"
Response Time Bids take 3+ weeks. Slow follow-up. Fast quoting. Defined multi-touch follow-up sequence.
Reliability Jobs abandoned. No-shows. Built by a Marine. Strict adherence to schedule.
Professionalism Poor site assessment. Hidden fees. Proper assessment. Technology-based project management.
Job Site Messy, unsafe work areas. Clean, organized, Marine-standard sites.
Project Control You manage the permits and city. A–Z management: plans, permits, and construction.

Jose Alfonzo Reyes, Owner of Reystone Construction

About Reystone

Built by a Marine. Run Like One.

Reystone Construction was founded by Jose Reyes, a Marine Corps Sergeant with a background in federal compliance and supply chain management. That same zero-defect standard applies to every residential project: verify before you build, document before you move on, close out before you leave.

The result is a contractor who doesn't disappear, doesn't cut corners, and doesn't leave you managing the process. One team, one standard, from first plan to final inspection.
