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.

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!

Seemed confident they could finish in one day. Matthew was very accommodating in meeting with the neighbors to assure them there would be minimal impact/disruption to their properties. There was a mixup in the lift provided and they needed a bigger lift. Matthew assured me it would be fixed at no additional costs to us. Thank you Matthew. Justus, Loa, Kaipo and Karl, were on site early to start on the project. Once the machinery issues with the lift were solved, they had the project done in a couple of hours. Took me up close to inspect the work and fixed another spot that was bothering me. So good to have this done. Want our building to last another 20 years and I feel this repair will insure this doesn't happen again. The crew had a lot of pride in their work. I totally recommend these guys to do a great job to your satisfaction.

The sellers remodeled the 1930's home and did a great job solidifying the foundation. Because the home was built long ago, we needed an expert 2nd opinion. Will took off of his busy schedule to do a walkthrough with my buyers and I. He did not just say, "looks good to me." He took the time to look at the pictures that I sent to him prior, then come and walk outside the home to look for an structural issues. Then when we viewed underneath the home, he gave us a detailed opinion. My buyers were extremely happy to get Will's opinion and they now have a peace of mind that their "Forever Home" is safe. Thank you Will! And by the way, he did not charge any type of fee. As a realtor, I need awesome people to refer to other people and I will be referring Will and Gundaker Works to anyone who needs his company's service.

They were always open to our suggestions and worked collaboratively with us whenever the job scope shifted to ensure the best results.
