Review of C & O Masonry Contractor (Manu) - Driveway Replacement, August 2025 After receiving several proposals for replacing my badly cracked asphalt driveway, I selected C & O Masonry Contractor. Their quote was competitive--not the highest, not the lowest--but what really set them apart was their professionalism. I had been warned by several of my local advisors that many concrete contractors in the area are known for demanding large sums upfront, only to delay work or disappear entirely. Thankfully, C & O proved to be the complete opposite. Initial Impressions:The owner, Manu, first contacted me via text and promptly scheduled a site visit for 2 PM the following day. True to his word, he arrived a few minutes early, presented his business card, and reviewed the project scope, which included removing the existing asphalt and installing a new 4-inch-thick concrete driveway with a border around my carport. One of my first impressions was the respectful and collaborative relationship between Manu and his son, who accompanied him. It was clear this was a man teaching his son the value of honest work--a detail that really resonated with me. Work Process & Execution:On August 20, Manu and his son arrived at 8 AM to begin work. (Unbeknownst to me, the excavator had already arrived the previous evening.) Over the course of three days, the crew removed the old asphalt, hauled it away in a dumpster, formed the new layout, and laid wire mesh. I later requested a minor upgrade to fiberglass rebar, which Manu handled with professionalism and ease--listening carefully and making the change without issue. On August 26, a full crew of at least 12 workers arrived along with a pump truck and two loads of concrete. In less than four hours, they poured over 22 yards of concrete, completing the job efficiently and with great attention to detail. While work was underway, three men dressed in casual business attire appeared and introduced themselves as union representatives or inspectors. They stood on my lawn and observed the project for about an hour, which only further reassured me that everything was being done to standard. Results:The finished product--driveway and walkway--is clean, precise, and has a beautifully sealed "wet look." I contracted Manu to seal the concrete right after the pour, and I'm very happy with that decision. My neighbors have since commented on how great it looks and how professional the crew was throughout the process. Final Thoughts:If you're wondering whether I would recommend C & O Masonry Contractor, the answer is a firm yes. In fact, more than just a recommendation, they will be my first call for any future concrete work. -- Louis from Kaneohe, August 2025 read more

C&O Masonry Contractor - Masonry/Concrete Near Me - Waianae, Hawaii

Our project consisted of removing an old asphalt driveway that was installed almost 60 years ago and replace it with a concrete driveway. This was roughly 500 square feet. Manu did an excellent job. My co-worker had referred him to us. Compared with other people on our street who have had similar work done, ours is really nice. He took the time to carefully remove the old asphalt and level the area. The following weekend, they poured and shaped the concrete. Note: Lopey's Welding built and installed our metal gate. read more

Good family business that will go out their way to achieve what you want. Very professional and friendly at the same time. We have him cement 2 driveways and a lanai area. My family is really enjoying the cemented space that use to be gravel. Thanks, Manu. read more

I used several concrete companies over a decade and Manu and his guys are the best. They added a slab and a long walkway on the side of our house and it turned out great. They are fast, professional, reliable, and left the place clean which was important to me. Several of my neighbors are already asking for an estimate from Manu when he was done with our project. i'm using them again to do add more steps and a long walkway to the other side of the house, and i would highly recommend them to all my friend. read more

Manu and his workers did an excellent job on my concrete slab and also cleaning up the unfinished work of another mason. I highly recommend him. Thank you Manu for everything! read more

C&O did an amazing job on my new 350 foot patio slab. I decided to go with stamping and staining instead of flagstone after I saw several of his projects and talked with the owners who were thrilled with the work from MANU. I called several concrete guys and he was the most reasonable and retuned my call immediately and came over to see the project. I have an existing concrete slab that I wanted to tie in with the new slab. He was able to lay new concrete over the existing slab and stained and stamped it perfectly. I love the look and have received so many complements. He is honest, hard-working and very reasonable. Highly recommend his work. they also built me a lava rock border for my garden. read more

Manu and his crew did a fantastic job on our project. We removed a few hundred square feet of concrete, installed a set of stairs out of rock, added veneer to a cinderblock wall, ripped out a concrete dog kennel, and poured a few hundred square feet of concrete. We do have additional concrete work in the near future and fully intend on having C&O Masonry take care of us! Thanks Manu! read more

We needed our concrete patio leveled out and some more drainage added to correct flooding issues. I called C&O Construction, they got back to me right away and came out same day to give me an estimate. They were very knowledgeable and professional and gave us such a great price that we hired them on the spot. If you can believe it, theey were able to start the work the next day!! Never had I had such amazing, swift service from any type of contractor!! The whole project was done in the 1.5 days they quoted me and the price never changed. We couldn't be happier with the level of service and quality of work that we received. If we EVER have more concrete projects, we are going straight to C&O Construction no doubt! read more

Absolutely wonderful experience working with Manu and his crew from C&O Masonry. I spoke to Manu on a Friday and explained to him what I wanted done for our extended driveway and for the sides of our house. He was able to set up an appointment the next day so he could evaluate the area and take measurements. Within a few days he give me a quote, his price was competitive and lower than other companies that I had previously contacted. Knowing that I needed to get the job done in a timely manner, we were able to set up a day and time. A week later Manu and his crew arrived on a Sunday and started the job. They arrived on time, were very respectful, knowledgeable, and was always available to answer any questions. They did a wonderful job and I highly recommend them for all your concrete needs! read more

We contacted C&O masonry to do a driveway, slab and repair to previous contractors slab at our residence. C&O owner Manu showed up the same day to give us a very reasonable quote. he understood what we wanted and even added his own professional opinions to make the project better. On the day of the pour Manu made sure everything went smooth and he made sure the work site was clean and safe. I'm a very picky person and expect the absolute best when paying someone my hard earned money and I gotta say it was worth every penny for a job well done and very professional. I will be contacting C&O in the future for sure. Mahalo C&O read more

I'm very happy with the work Manu provided. He worked with me on the project I have been wanting to get done (remove gravel and replace with concrete). I totally recommend Manu. Great service, price, and his professionalism. Mahalo! read more

so i needed their services for some improvements to my yard; i called them and scheduled an appointment. Waited all day for them but they didn't show up; not even the decency to call to cancel. Highly unprofessional. Hate people like that read more

Very very disappointed...called Manu from outer island a week before flying into Oahu to schedule an appointment for an estimate. The day before the appointment, I text him a reminder and he responded, ok. The day of the appointment, "no show ". I called him about thirty minutes after the appointment time, his reply, he forgot. Ok that happens, so being the patient person that I am I offered him if he wanted to reschedule. Yes Manu said so rescheduled for the next day at 9:30am. AND again "no show" AND no phone call. So I had no choice but to move on . Shame on you Manu and a businessman! read more

We were very pleased with the fare pricing and great quality of work Manu performed at our house. It started with trying to find a concrete worker that could fix a job that a previous contractor had done wrong. I was impressed from the beginning when I called C&O after reading a review on yelp. So many contractors do not return calls or if they come to your home to give a quote the say they will have it ready in a few days and either don't call back or you have to call them. When I called Manu he was very professional he came to the property within 1 day and was able to get us a bid within a day. He explained why he would need to redo the work the other contractor performed in order to make it right and have the water flow away from our home. He completed the job pretty fast considering rain was an issue due to several hurricanes that were coming to Hawaii. His pricing was very fare and he communicated when there was any weather factors that could affect the timing of the job. We were so pleased with the patio work that we then hired him to come back and resurface a cracking moss rock wall install a walkway behind our shed that he stamped and stained and also had him build a moss rock veneer base that would support our 8ft. Coconut tiki statue in our yard. We would highly recommend Manu for any concrete stone work . All the best Manu for a successful business! Jerry & Byron read more
