The Structure Everything Else Depends On
Finishes can be changed. The foundation and the frame cannot. That is why we treat every layout line, every footing and every connector like it matters, because it does.
Foundation and framing in one crew
No finger pointing between trades. The team that pours the foundation knows exactly what the frame needs.
Built to plan, ready for inspection
We follow the drawings, the hardware schedule and the nailing pattern so inspections go smoothly.
Clear, written estimates
You get a detailed scope and price before work starts, with no surprise add-ons.
Clean, safe job sites
Organized crews, protected property and a site you are not embarrassed to show the neighbors.

What Our Clients Say
★★★★★ 5.0 average rating
Sample reviews for this demo. Replaced with real Google reviews."GTKN framed our two-story addition and passed framing inspection on the first try. The crew showed up on time every day and left the site clean. Could not ask for more."
Los Angeles
"They poured the foundation for our backyard ADU. Everything was square, the bolts were exactly where our framer needed them, and they explained each step."
Glendale
"Our 1920s bungalow needed a seismic retrofit. Fair price, quick work and they were respectful of our home. We feel a lot safer now."

Frequently Asked Questions
What areas do you serve?
We are based in Los Angeles and work throughout LA County, including Glendale, Pasadena and surrounding cities. Call us to confirm your location.
Do you offer free estimates?
Yes. Call (323) 253-4423 or send the estimate form with your project details and plans, and we will get back to you to schedule a visit.
Do you work with homeowners or only contractors?
Both. We work directly with homeowners on additions, ADUs and retrofits, and we partner with general contractors and developers on new construction.
Can you do both the foundation and the framing on my project?
Yes, and it is one of the best reasons to hire us. One crew handling both stages keeps dimensions, bolts and hardware coordinated and keeps the schedule moving.
Do I need plans and permits?
Most structural work in Los Angeles requires permits and approved plans. If you do not have plans yet, we can recommend designers and engineers.
