    Patio
    Don M.

    We needed a patio equal to ground level in our backyard so our special needs daughter could walk safely. They built it perfectly and we're easy to work with.

    Sergio created a beautiful step-down backyard patio space for us that we can't wait to use this summer. He's very responsive, and went the extra mile helping us with the details and taking care of things that came up during the process to make sure we were happy with the finished product. Both him and his team were easy to work with, and I'll definitely use Allison for future projects.

    In their website they state that they do residencial jobs. Very disappointed of this company.

    This what they sent me after a estimate request. I attached a picture of a patio for the estimate.

We also had a backyard with a 40 degree slope and was difficult to access and navigate. Both owners Malika & Alex came out and listened to our concerns and shared their vision on how to transform our side yard and backyard slope into something that addressed all our concerns. They even provided one the spot renderings so we could envision what the final outcome would be. I can't begin to explain how they turned our project into something that is showcase quality. Their attention to detail and professionalism is of the highest standards. The crew were respectful of property, genuinely professional and they completed our project in record time. I think this company from the top, down to the crew are hands down the best company in the area.

    I highly recommend using this company for your backyard pavers project. I called Alex out for 3…read moreseparate estimates before we landed on a final design. His pricing was upfront and very reasonable. We had to end up building a retaining wall that we didn't originally plan for, but every project has its unknowns. Alex and his team were able to pivot quickly and get the job done with great attention to detail. I'm going to call him back this fall to get some trees as well. Highly recommend giving them a call.

It just about looks like where the concrete is going to eventually crack? It's been a couple months now but maybe it takes longer for that to go away? The patio roof is fine on the straight part, other than the sections are not even - couldn't put the skylight where we wanted because it wasn't 24 inches wide so the skylight wouldn't fit there. all of their crew did not know how to properly fit the 90 degree angle side to the straight side. one side of the angle was not attached properly, but the other side was done correctly. Looks like one of their guys knew what he was doing and how to use the connecting metal brackets but the guy on working the other side of the beam did not. Even though that section will eventually be covered up/closed off with a ceiling it looks unprofessional. Also, on the front facing side of the roof there was a board that stood up in the inside corner that would not allow the roof flashing to lay flat in the inside corner that would hinder the water flow that would be draining to the gutters that we had to fix.

    We had a very broken 1910 sidewalk that needed replacement…read more H20regon Concrete offered us everything we hope for in contractors: a fair price, great communication, on-time arrival, a strong work ethic, and quality workmanship. (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.

Vai came out and we decided to fill the cracks with epoxy, I mentioned at that time we'll see how it looks in a few months. Now I have more cracks on almost every square and steps. Emailed video, texted and tried calling 3 times and no call back or reply to email or reply to text. Would I use them again, No. Would I recommend them, No. Actually had a person walk by and asked who did the concrete and I didn't say who. Terrible customer service.

I called 3 references and talked to two, including the church mentioned in another review. All said their work was satisfactory. This business does not have an Oregon CCB license. When I asked about that I was told by Jacob that they were working on it. That should have been my first red flag. The price they quoted seemed reasonable based on a previous quote I had been given a few years before. When they came the next day they did a good job of power washing, although we had to expressly ask them to clean up the dirty overspray mess they made of our back porch. Neno made a lot of promises about how he would come back if there was something we were not satisfied with and they even wrote on the invoice that they were giving a 3 year warranty. At the time I questioned why the cracks didn't really look like they had been filled. They told me to wait until it dried and it would plump up. The next day I sent them a few pictures of areas that hadn't been sealcoated at all. I have given up on expecting the cracks to have been filled. They responded once saying they would call me when they finished the current job they were on. I never heard back from them. A few days later I called from a different phone and Neno answered. I explained that I was trying to reach them to have them sealcoat the areas they had missed. He set up an appointment for 11:00 am the next day. They never showed. I am sure their 3 year warranty isn't worth the paper it is printed on. In general, their work was substandard and their business practices were dishonest. I hope this review will save someone else from making the mistake of hiring Neno and Son Sealcoating and Asphalt 1738 SE 32nd Ave Hillsboro, OR 97123 Business Phone= 971-440-7682
