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.

I just told them I needed to wait for The City's approval prior to moving forward. Well in that timeframe they decided they didn't want the job and haven't answered calls, texts, or emails since.

So yes it looks like they do good work, but they might also leave you high and dry, so avoid them if you value peace of mind and reliability.

(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.

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!
