They are honest, open, communicative, and work like crazy to get the job done! Bill does really high quality work - he always explains in detail how he's tackling the job and sends a ton of photos so you can see what he and his team are doing at every step. One of my retaining walls (see photos) is in a really precarious location on a public sidewalk next to a busy street, but Bill and his team were able to handle it like true professionals. He estimated the work would take a few weeks, but after assessing the situation he decided that they needed to get the sidewalk cleared as quickly as possible so that people could walk by, so he brought in reinforcements and finished this wall in three days. Three days!!! No exaggeration - the "before" photo was taken on a Thursday, and the "after" photo was taken on Saturday! I have no idea how he pulled that off, but I so appreciate that he worked so hard to get the wall done quickly and cleaned up the area perfectly so that my neighbors wouldn't get mad at me :D Long story short, I feel really well taken care of by Bill and Sue - they treat you like family and I absolutely love my new "hawaiian style" wall :) Mahalo Bill and Sue!

Really poor communication! In March 2026, we signed a contract with 4-Belt to do some sidewalk…read morerepair mandated by the city. On the day Tulanga was supposed to start, no one showed up. I waited a few days and then contacted him. "Oh - family emergency, we will start next week." Next week comes by and still no one comes. I wait a few days again and contact him again. "Oh - I injured my foot - next week for sure." I wait for the next week and again no one shows up. I wait a few days and contact him. "Oh - my foot is still injured - but next week for sure." Guess what - he did not show up the next week and then just stopped responding to my texts. I understand that delays come up but why is it my responsibility to have to repeatedly contact him when no one shows up on the scheduled date again and again? If something comes up, LET ME KNOW! And if you don't want to do it, LET ME KNOW! After a month of having my texts ignored, we gave up on him and contracted with the city to do the repair.

These guys were super friendly and fast. I will definitely call them again for other concrete work.read more

(We've been getting a steady stream of compliments about the new sidewalk from passersby.) But what really made this company stand out was the people. Every one of the team members was genuine, thoughtful, kind, and friendly. We thoroughly enjoyed meeting them, and learning about each other. After they finished the job, we asked them if they might be willing to move a giant pile of sod that had been sitting in our back yard for two years. They came back out with the same great attitude, did the job at a fair price, and cleaned up the work site afterwards. We couldn't be happier. When it's time to replace our other old concrete, we won't hesitate to call them. If you're in need of concrete work, call these guys first. You won't be disappointed.

Tavake and his crew are absolutely amazing and I'm delighted to provide this review. This is the…read moresecond time we've called him and he just finished our beautiful new stamped concrete walkway, a stamped concrete pad off living room and kitchen, as well as a small grill pad for our new grill gazebo. We LOVED his work and the group was incredibly efficient. They cleared and poured on Day 1, and came back to seal and clean and pick-up bright and early on Day 2. Tavake and the crew are PROMPT and always arrive early. Tavake came right out to meet us, give us a bid, and got us on his schedule immediately. When we weren't sure what we wanted he offered some ideas and they turned out to be even better than expected. ALL of our neighbors and friends have complimented us on how the project turned out for us and have asked us to pass along Tavake's contact information (which we were happy to provide). We think the world of Tavake and he's again one of our preferred contractors. PS. He also poured our new driveway three years ago. After seeing how our driveway turned out, two of our neighbors just down the street from us snagged bids from him and then used him for their driveways as well so we were lucky to see him again for a few weeks on two other jobs in our neighborhood. We wish him THE best and highly recommend him!

I just want to praise Allison Concrete Construction and the ways in which they have improved our…read moreproperty and our lives. We hired Allison Concrete to build a retaining wall behind our barn in 2022. It was next to impossible to get a company out to our property at that time to build the wall, with different companies giving me a variety of excuses. And, then, I called Allison Concrete. Sergio came out and gave me a very reasonable bid and started the work in a timely fashion. We didn't have to wait 3 - 6 months as was the case with more than one company. This year, we had an immediate, and very urgent need, to have a rock retaining wall built due to a failure in the fall by another company. We, again, thought of Allison Concrete in hopes that they could correct the failed wall and my wife's broken heart! Sergio came out "same day" to assess the disaster and see if he could remedy the situation out front. We received Sergio's extremely reasonable bid within 48 hours and quickly hired him to get the job done. Much to our surprise, Sergio put us on his schedule the following week. Within 2 days, Sergio and a helper created the most beautiful wall to the point that we could hardly remember the muddy disaster that we had to look at all winter through our kitchen window!! Correcting the failed wall and building a new wall was a big job and took a large backhoe as well as artistic skills to construct, as some of the large rocks/boulders weighed about 2000 pounds. We are looking at hiring Allison Construction for another job that just came up; concrete footings for a gazebo that will be built above our hot tub. Not only is Sergio the epitome of a true professional, he has a heart of gold and has a sincere desire to see his customers satisfied and happy! My wife is extremely happy with her new retaining wall! Sergio is always on time, cleans up his work space at the end of each day and works hard with no breaks that we saw! In a world of questionable contractors, Allison has never let us down or ever leaves us with any questions, doubts or concerns. If you're looking to hire the best, then Sergio is who you need for your next job!

I shouldn't have. He kept delaying when he would do the job, finally just announcing they'd be there the next day. That wouldn't have been that much of a problem, even though it was sudden, except that I'd been asking him for a contract proposal for a week and he'd kept telling me he'd get to it but didn't. I finally told him that he couldn't come the next day (it was after 6pm by this point) because I still hadn't seen a proposal and wanted a chance to look it over before they started and wouldn't have a chance to do that due to his delays. All of a sudden, he texted me that I'd have to find another contractor because I was too difficult to work with. Because I'd asked for a contract for a $5000 project, to protect both of us, and wanted more than 12-14 hrs to read it over. I'm ultimately glad he showed his colors early, I have no confidence at all that he wouldn't have just stolen my money and vanished. Extremely unprofessional and very shady. Research other contractors, this is not normal behavior.
