    Concrete retaining wall & chain link fencing for community garden and food distribution

    Will, Mark and the rest of the team from Gundaker Works has been incredible to work with! They have exceeded our expectations in every way and we can't recommend them enough for any job big or small you may have. Mahalo nui to the Gundaker crew!

    In February 2016, we lost our North shore seawall due to extremely high surf. Our beach home that our family had since the 50s was literally hanging by a thread. I contacted multiple companies and had them come and look at the house and the wall. No one wanted to take the job. Structural Systems Inc. recommended I call Will from Gundaker Works. I got a hold of Will and he was at our beach home at 6:30 AM the next morning. Will looked at the damage and told me that he and his team could help. I was in tears! He immediately mobilized a team and started bringing down equipment and supplies to help save our house. It was the day before the 2016 Eddie Aikau was held at Waimea Bay and we had a very short window to save our house and prepare for the high surf that was slated to hit the north shore that very night. With the leadership of Will, Mark, and the help of their team along with our neighbors, they saved our house that night! Gundaker Works repaired our wall and our home to make sure that this would never happen again. Will and his team are a class act. Very experienced and made it all easy for me. They constantly communicated with me and helped me navigate the permitting, regulations and the insurance claim process. They worked within my budget and always offered options for me to choose from. The Gundaker Works is like family to us and we will never go with anyone else. Not only are they extremely talented but they are overall great people to work with! We HIGHLY recommend them!

The other places wanted me to hire an engineer (over $6k) to diagnose the problem. But Jeremy did that at the beginning. I don't know anything about this process, but I trust these guys did a great job. The workers came in a timely manner, stayed working under my house for about 3 days. I could hear them laughing and enjoying their work. Great guys, good attitudes and worked hard. Took pictures, I forgot to save. But they drilled and put push piers in and used something to shoot into the cracks like a steel cement. They had affordable pricing and as far as I know did a great job to stabilize. I'm glad I went with them.

Our insurance did not cover the damages or cost to fix. We finally were able to get some financial help last year to address some major issues for our 1990 home. Foundation Support Of Hawaii, was a God sent! They literally came to our rescue! Jeremy did the initial walk through of our home, and worked out a plan & affordable cost. Renee was the next person to contact me & she had been a pleasure keeping me updated & informed of the cost & payment plan. Then came the hard workers/crew from Foreman, Raymond "Augie" Augustin, to the crew made up of Gabriel, Russell & "D" Duane! The crew was always on time and kept in touch with me. I most appreciated that "communication" was always there! They were very friendly to me and my whole family & very respectful, hard-working and fun! We appreciated all the work, skills, and expertise of their craftsmanship! They always explained what they were doing and asked if we had any questions or concerns. We have so much Aloha & Gratitude for them. Great work, guys! "Mahalo Plenty", from the Richards-Fung Ohana of Waimanalo.

He was incredibly friendly, approachable, and answered all of our questions with ease. Once we had the structural design upgrades, Damien and his team went above and beyond to find cost-saving solutions that maintained the home's integrity. The crew worked diligently--even through the rain--and left the site clean. They even used the displaced rocks to build us some beautiful rock planters! Thank you to Damien, Johnny, and the entire Structural Systems team for a job well done.

They were scheduled to complete the spall repairs, painting and tile in the lanais only, Is the work supposed to take this long?! We have 10 units on each floor and there are 22 floors. We were told to remove everything off our lanai in July 2024. They never got to my unit until right before Thanksgiving 2024. Mind you, I had lanai furnishings taking up space in my living room that entire time AND I was only able to put them back on the lanai after Christmas 2024, Didn't even have room for our Christmas tree. Additionally, they came back in July 2025 to paint the lanai. I had to call them to clean up the concrete left all over the lanai and it took them a couple weeks to send 2 guys. When they finally came back, these 2 guys didn't have the right "concrete cleaner" and had to come back another day. They took half a day and it still isn't as clean as it was before they started the spall work. The only saving grace is that the workers I've had contact with are friendly and respectful when interacting. Now we had to remove everything from our lanai again because they were going to redo / update the tiles. So many residents complained about the work, the cleanliness and the rate of completion it took! We had to have a special resident meeting about it. Hope they never call this company again!

Living on a hill, our house had been shifting dangerously over the years. When we chose to work with Anchor Systems Hawaii, Eric visited us several times to personally inspect the site and clearly explain the necessary process. Communication was seamless with Eric and his son, Tony, and the entire crew kept us informed every step of the way. They were always open to our suggestions and worked collaboratively with us whenever the job scope shifted to ensure the best results. The crew was a group of hardworking, considerate professionals who truly mastered their craft. Not only was the final product top-notch, but they even went above and beyond by power washing our driveway and finishing small tasks that weren't even in the original proposal. A few months after completion, Oahu was hit by the worst storm in decades. Everything held up outstandingly, providing us with immense relief. I cannot recommend them enough
