Los Angeles County · Licensed general contractor
The work holds up close.
Reystone is a Los Angeles general contractor building residential and commercial projects with careful execution, clear communication and attention to the details that remain long after construction is complete.
The company is owner-led. The person who walks your property and writes your estimate is the person who runs the job, holds the trades to that scope, and deals with you directly when something needs deciding.
About Reystone
Residential
Homes across Los Angeles County. Living space added where there wasn't any, and rooms rebuilt to work the way the house should have worked in the first place.
ADUs & garage conversions
Detached units and garage conversions, from plan check through final inspection.
Kitchens & bathrooms
Cabinetry, tile, plumbing and finish work, sequenced so the house stays livable.
Additions & renovations
Room additions, second stories, and houses taken down to the studs and rebuilt.
Selected work
Photographed as built, including the parts that end up behind drywall, so you can see how a job was put together and not just how it turned out.

How we build
Most of what goes wrong on a construction project goes wrong before anyone picks up a tool. These three things are how I keep that from happening on yours.
One point of accountability
No account manager, no handoff to someone who never saw your property. I price the job, I run it, and I answer for it. Qualified subcontractors and specialty trades do the work their licenses cover, coordinated by me and held to the scope I wrote. My dad works with me. I grew up on his job sites, which is where I learned the difference between done right and done fast.
Everything in writing
A written scope before we start and a written change order before anything moves. You will know what is happening this week, what is happening next, and what it costs, before the work is done rather than after.
Documented as built
Every job is photographed through framing, rough trades and finish. You get the record of what is inside your walls, and I get work I am willing to show people before the drywall goes on.
Owner
Jose Alfonzo Reyes
I grew up carrying material for my father on job sites around Southeast LA. I served in the Marine Corps, built a career outside construction, and earned a master's degree at USC before coming back to build. Reystone is my company, my license, and my name on the permit.
I keep the job list short on purpose. Fewer houses at once means I'm actually at yours.
The longer story →Commercial
Tenant improvements, renovations and specialty scopes for property owners and facility managers, including doors, frames and hardware. Occupied buildings, working schedules, and work coordinated for inspection.
