From the very first meeting, they were organized, professional, and transparent about the entire process, from utility verification to permitting and final installation.
The drilling itself was executed flawlessly, and what stood out most was how smooth the whole project went. No delays, no hidden surprises, and everything wrapped up on schedule and within budget. You can tell they take pride in their work because the end result speaks for itself.
If you’re planning underground utility work or EV charging station installs in San Diego, Devco is the contractor you want on your side. I couldn’t be happier with the results and would gladly recommend them to anyone.

We brought Devco in for a turnkey underground project in Orange County, and they absolutely knocked it out of the park. Their crew began with careful potholing to verify utilities, then handled the concrete and asphalt excavation quickly and without any issues. From there, they completed the directional drilling and pulled multiple conduits right on target.
The part that really stood out was the restoration. Once the work was finished, the backfill and asphalt patching were so clean that you’d hardly know the site had been touched. Throughout the project, their communication was clear, safety was prioritized, and the schedule stayed on track.
For anyone in Orange County looking for dependable underground utility work, from directional boring to trenching and restoration, Devco is the team you want. We’re extremely happy with the results.

We recently hired Devco for an underground utility project in Orange County, and I have to say the experience was excellent from beginning to end. The scope covered directional drilling, trenching, and potholing, plus all of the restoration once the utilities were in place.
What impressed me most was how smooth they made the entire process. Their team stayed ahead of schedule, maintained a safe and tidy jobsite, and handled the unexpected without slowing things down. Communication was clear the whole way through, which made our job a lot easier.
Finding one contractor who can take on every aspect of underground utility work is rare, but Devco truly delivered a turnkey service. We couldn’t be happier with the final result and look forward to working with them again on future projects in Orange County.

Devco really impressed us on a recent project in Orange County. They started with hydro excavation to expose and confirm all existing utilities, using their hydrovac trucks to get everything located quickly and safely. Once that was complete, their crew handled a long directional drilling run with precision — the bore was clean, accurate, and ready for our pipe install without any issues.
What stood out was how seamlessly they combined both hydro excavation and directional drilling on the same job. The coordination between crews made the process efficient and stress-free for us.
If you’re taking on an underground utility project in Orange County, you won’t find a more capable and professional team than Devco.

We recently hired Devco for a full turnkey underground project at one of our commercial properties in Los Angeles, and I honestly couldn’t be happier with how it went. These guys handled everything — from trenching to directional boring and hydro vac services — and made the process smooth from start to finish.
If you’re looking for a solid directional boring company in Los Angeles, Devco is it. They showed up on time, communicated clearly, and knocked out a really complex job with no drama. The hydrovac team was super professional too, especially considering how tricky our site was with buried utilities.
It’s rare to find a crew that can manage all aspects of an underground utility project without needing a bunch of different subs, but Devco really is a one-stop shop. Highly recommend.

I just wanted to take a moment to express my appreciation for the outstanding work done by Devco's Directional Boring on the recent potholing project. From start to finish, their team was professional, efficient, and highly skilled.They showed up on time, communicated clearly every step of the way, and made sure the job was done right — and done safely. Their attention to detail was impressive, especially when working around existing underground utilities. What really stood out was how clean and organized the site was after they finished — something that doesn't always happen in this line of work.It's rare to come across a company that combines quality work with great service, but Devco definitely delivered on both fronts. I wouldn’t hesitate to work with them again or recommend them to others. Thank you, Devco, for a job well done.

We hired Devco for a full turn‑key project directional drilling in San Diego, and they absolutely delivered. The crew started with precise utility locating via potholing, then handled all the concrete and asphalt excavation without a hitch. Once everything was clear, they completed the directional drilling and smoothly pulled in both a 2‑inch and a 4‑inch conduit exactly where we needed them.
What really impressed us was the finish: they backfilled and restored the asphalt so cleanly you’d never guess the area had been opened up. Communication was solid the whole way, scheduling stayed on track, and every step felt safe and professional.

I recently hired Devco Development & Engineering for a challenging Directional Drilling project in Torrance. From the start, their crew impressed us with meticulous utility potholing and hydro excavation to safely expose every existing line. Once everything was verified, they smoothly drilled and pulled in two 4‑inch conduits exactly as specified.
Even when unexpected hurdles (completely outside of Devco’s control) popped up, the team stayed calm, communicated clearly, and kept the schedule on track. Their commitment to safety, clean work areas, and a flawless end result exceeded our expectations.

We recently hired Devco for a directional boring project that required hydro excavation and utility potholing to safely locate existing underground utilities in the bore path. As both a commercial real estate broker and active developer, I've worked with a lot of contractors—and I can confidently say Devco stands out.
They handled the entire scope full turn key, from planning and utility coordination to the actual boring and restoration. Their team was knowledgeable, professional, and efficient, and they kept us updated every step of the way. The hydro vac crew was especially impressive, working safely and precisely to expose critical lines without issue.

We had Devco handle a full turn-key underground job for us in San Diego, and they did an amazing job from start to finish. The project included utility trenching, directional boring, utility potholing in San Diego, and even building out some concrete pads.
The crew was professional, on time, and really easy to work with. They kept the site clean, worked safely, and stayed on schedule, even with a few unexpected things that popped up.
It’s not easy finding a company that can handle everything underground, but Devco took care of it all. We’re really happy with the results and would definitely use them again on future projects.

Devco did an amazing job on our project in San Diego! They did a directional drilling job and drilled over 1,000 feet. They also completed the utility potholing and found all the underground utilities, and even restored the asphalt and concrete after backfilling. They handled everything from start to finish, so we didn’t have to worry about a thing.
The team was friendly, professional, and really knew what they were doing. They finished the job on time and made sure everything was done the right way. If you need drilling or underground work, I highly recommend Devco. They made the whole process easy and stress-free!

I can’t say enough good things about the team at Devco Development & Engineering. They recently completed a turnkey directional drilling project for us in San Diego, installing underground infrastructure for our car charging stations. From day one, their team was friendly, organized, and really knew what they were doing. They walked us through every step—utility checks, permits AND executed the directional drilling flawlessly.
I really appreciated how smoothly everything went. There were no surprises or delays, and the entire project wrapped up right on schedule and within the budget we’d discussed. It was obvious they took pride in their work, and it showed!

Devco's Directional Boring services in Los Angeles were outstanding. Beyond just boring we also had them handle the entire project, full turnkey.

Devco did an outstanding job on our project in the Los Angeles area! They began with potholing using hydrovac trucks and hydro excavation to safely and accurately locate existing utilities, ensuring the job was done right. Once the utilities were verified, their team completed a flawless 300' directional drilling run, reaming the hole perfectly to fit our pipes. Their expertise in both hydro excavation and directional drilling made the entire process smooth and efficient.

I recently had the pleasure of working with Devco in Long Beach, CA, and I couldn't be happier with the results. They completed a directional boring project for us that required some utility potholing and hydro excavation along the way. Their team was incredibly professional and efficient, placing about 2,000 linear feet of 4" conduit with precision.
From start to finish, Devco ensured that the job was done safely and on time, all while keeping us informed throughout the process.

WOW…What can I say, the DEVCO team saved me thousands of dollars in my electrical panel upgrade at my home in Temecula, CA. I was informed about a process called horizontal direct drilling as an alternative to trenching up our yard, our landscape, pavers, and concrete. DEVCO explored all options with us, and with their expertise, we did the directional drilling, completing the project in 2 days, and saved thousands of dollars in labor, and repairs. Thank you DEVCO for taking your time with us, as this was our first time and only time doing a project like this for our home. You are the best!!
