    We really appreciated Derel's integrity and trustworthiness. Under his Leadership, this crack crew worked well together and in sync.
    Leitu K.

    I'm an assistant pastor at my church. Whenever I saw Derel with his men, I saw a respect and love for each other that can only come from integrity and trust over time spent with each other. I bought these men coffee and doughnuts but they had already eaten breakfast that Derel bought for them. Treating men that way brings a kind of love and caring we see in the Bible that comes from our Savior, Jesus Christ. That kind of kindness and compassion accomplishes much in how it translate's into a man doing the best he can for not only his superior, but for the customer especially.

    Awesome work from Derel and his team. Very reliable. From the first consultation/estimate they proved to be very knowledgeable and honest. Highly recommend for any Masonry work.

    Before and after.

    Laid some concrete for us. Was a great communicator. Was timely and left area clean. Was available within days of first contact. Even took away extra debris for us and stopped by a few days later to tidy up some edges. Prices were reasonable and in line with other quotes we received.

For this project we reached out to five companies and he was the most responsive. He gave us a quote right away and took the time to meet us for a relatively small job. We hope to use his masonary servies in the future and if you have a concrete project you've been wanting to complete, you should abosolutely include Maka's Akamai Masonary on the short list, and you are likely to choose him.

He lied about the progress of the work and asked for payment without completing the work under the agreement within the timeframe promised. Weeks and months have gone by and the work was still incomplete. Basically, this was a breach of contract and he failed to perform the agreed-upon work as outlined in the contract. For months, he was unresponsive despite multiple attempts to communicate to either finish the work or refund the payments made. After 5 months, he finally responded stating that he'll set up a repayment schedule to return the funds due to the breach of contract. Another 4 months have gone by and he has yet to repay any of the advance payments made. During those 4 months, multiple demands were made for the refund of payments made. He has been unresponsive. To date, 9 months later, he has failed to return the payments made. No effort at all to even set up a repayment schedule. His conduct has been unprofessional, unreliable, and has caused significant financial and personal inconvenience. I trusted him and paid him in advance when he asked for more money stating that he needed more funds to cover the rental equipment and pay his people. Never again with Maka. I plan to file a formal complaint with the appropriate licensing board and the BBB.

From the beginning, Leo always showed up when he said he would. First, to check the site and provide an estimate. Then second, to perform the demolition. They worked efficiently and finished the job earlier than expected. When I went in to inspect the demolition, I was pleased to see how neatly they did the job. They were careful not to damage the abutting walls and cleanly disconnected the plumbing. This will make it easier when the remodeling takes place. Overall, for the amount of work they did, manpower used and time it took, the price was right. Leo also gave me some suggestions on repairs around the house that were very helpful.

We had an idea on what we could do and got quotes with that in mind. We got several quotes regarding what we wanted to do (basically lots of concrete) prior to Leo coming, but once he did he suggested a better solution than the one my husband and I proposed! Other companies were professional with great quotes, but I like that Leo thought outside of the box and gave a great solution that actually was cheaper and less work. He was very professional with great communication. Things were delayed due to rain outs on another job of his, and the plan changed as we had another contractor come that was originally scheduled after him. It actually changed the scope of work slightly because, we wanted the drainage to work on tandem with new downspouts and where the spouts were placed wasn't where we thought they'd be! Leo was great and flexible, he even explained why the rain gutters guys suggestion wouldn't work with our property, when the worker suggested something else. He also worked around the changed downspout area, which I should've let them know beforehand, but slipped my mind till an hour in. Thankfully, Leo came up with a great idea again and worked around it. His crew was super fast and the job was done within a day. I'd totally recommend them to anyone.

    I've been trying to get my royal palm trees serviced since October 8, and this has been one of the…read moremost frustrating experiences I've ever had with a landscaping company. Communication is extremely poor. Responses regularly took up to a week, if I got one at all. This was not a small or inexpensive job -- I was charged $3,769 -- yet the level of professionalism was completely lacking. After the work was done, even the company acknowledged that the job was handled terribly and agreed a refund was appropriate. I was told a refund check had been sent, but no tracking number was ever provided, and I never received anything. At this point, they are now refusing to issue the refund altogether, despite previously admitting fault. What makes this even more concerning is that when looking at their Yelp reviews, one of the few positive reviews appears to be written by the same person I was communicating with directly "Kaili D.". That seriously calls into question the credibility of the reviews on this page. Overall, this company took a large payment, delivered poor service, communicated poorly throughout, and then failed to follow through on a promised refund. I am extremely disappointed and upset with how this was handled and would strongly caution others before hiring them.

I contacted Sione for a quote and he was quick to do an on site inspection. After getting the HOA approval, I scheduled the work.

But I like to know what's going on to schedule my day out and when the leave the side gate unlocked. Sione was able to schedule Randy to spray for underground termites prior to the pour. The work was completed in 3 days. There were some finishing touch issues with the completed work but Sione sent a couple guys out to fix the issue.
