About Us
A San Diego drywall company
that actually shows up.
Diamond Drywall is a licensed C-9 contractor based in San Diego, California. We hang drywall, frame light-gauge steel, and finish to spec — for commercial GCs running buildouts and homeowners finishing custom homes.
Our Story
Built on the corner of "precision" and "show up on time."
Diamond Drywall was founded by David in San Diego with a simple goal: be the trade partner that GCs actually want on speed dial. Not the one with the cheapest bid — the one whose framing is plumb, whose drywall is hung clean, and whose finish doesn't need a callback two weeks later.
That principle has carried through every project. Whether it's a 12,000 sf medical TI in Mission Valley or a single popcorn-ceiling removal in La Mesa, we treat every job like it's going to be photographed.
Today, we work as a trade partner to general contractors across San Diego County for commercial buildouts, multi-family, and ADU production. We also work directly with homeowners on remodels, custom homes, and one-off repair work.

What We Stand On
San Diego · est. 2015
Four principles, no exceptions.
-
Show up on time, every time.
A schedule is a promise. We pull from it religiously.
-
Build to plan, finish to spec.
If the spec says Level 5, you get Level 5. No "close enough."
-
Communicate before you're asked.
Daily updates from the foreman. No silent crews.
-
Clean it up before you leave.
Daily site cleanup is non-negotiable. We leave it broom-clean.
By The Numbers
Reviews
From the people we work for.
"Diamond hung and finished a 12,000 sf medical TI for us on a tight schedule and never blinked. Their Level 5 finish under the new LED grids was clean — no callbacks."
M. Reyes
Project Manager · San Diego commercial GC
"We had a water-damaged ceiling in our master bedroom from a slab leak. They cut, patched, retextured, and matched the orange peel perfectly. You can't see where the repair was."
Jennifer L.
Homeowner · La Mesa
"Used Diamond for the framing and drywall on three of our ADU projects this year. They're on plan, on schedule, and they communicate with our supers daily."
R. Patel
Owner · North County ADU builder
"David and his crew came out for a small repair and treated it like a $50k job. That's why we keep calling them for everything."
Carlos M.
Property Manager · South Bay multi-family portfolio
"We needed metal framing for a complicated medical buildout — curved soffits, shaft walls, the works. Diamond came in under bid and three days ahead of schedule. Foreman ran his crew like a Swiss watch."
A. Nguyen
Senior PM · Mission Valley healthcare GC
"Our restaurant build needed Level 5 finish on every visible plane for the dining room. They were the only bidder who explained the difference between Level 4 and Level 5 without me having to ask. That confidence is why they got the job."
S. Hartman
Owner · North Park restaurant group
"I'm an interior designer, and Diamond is the only drywall crew I trust to match custom textures to existing walls in older homes. They bring sample boards. They test on cardboard. Nobody else does that."
Marisol C.
Principal Designer · La Jolla design studio
"Insurance claim job — flooded condo, three rooms gutted. Diamond handled the scope documentation with my adjuster directly. Reopened the unit two weeks faster than I expected. We use them on every claim now."
