    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.

    Neno and Son Seal Coating and Asphalt were going door to door in my neighborhood. I agreed to have…read morethem power wash, crack fill, gator patch and reseal my driveway. 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

    Be aware: Your estimate may be nowhere near your final cost…read more We purchased a house that had a shop with squirrel burrows under it. I called TerraFirma and a couple other companies to get quotes. RJ arrived and I explained the issue. He took about 45 minutes to inspect and gave me an estimate for under $4,000. I was happy with that, signed the agreement, and cancelled the other companies' visits. A date was scheduled for a month later (just before Christmas). The technician Jeremy arrived on time and prepared. He was easy to get along with. A few hours after he informed me that he finished about 1/3 of the shop and that was all the foam in the estimate. He told me that he could stop or continue, but there is an extra cost. I felt like I really had no other option but continue. Jeremy seemed to empathize with the situation I was in and did what he could to keep the cost down. After all was set and done, my $4,000 estimate had turned into almost $10,000. I was unable to get in touch with RJ to talk about it at the time. He left a voicemail stating he was on vacation, but would elevate it with the team. After the new year I left voicemails with Victoria, the project manager, several times over a week and a half with no return call, even though being told she was in the office. I finally explained my issue with the person who answered the company's main line and that I had left several messages with no response. She advised that she would send an urgent note to Victoria and her boss. The next day I received an email from Victoria simply stating the technician had already given me a break and that I signed the authorization for additional work. I understand overages and that estimates are just a best guess, but my final cost was way over twice the original estimate, my calls were ignored, and the company does not seem to be concerned that my project was $6,000 over the estimate. Needless to say, I will not be doing business with them again.

    Living in a 30-year-old home for the past two decades we've had several phases of upgrades, but one…read morething has always been absent from a 10x10 slab on our back porch: a hot tub. So, this summer, we decided to move forward with the plan to be "soakin' for the holidays" three months away. The only thing standing in the way of that dream: the slab and its neighbor had sunk a few extra degrees, roughly three inches, at the far edge. We were going to need to shore up and permanently stabilize this slab if our hopes of the (3-ton when filled) tub were going to materialize. I made a quick call to Terra Firma and they had an estimator out within a few days. The pricing was reasonable and had the standard 50% up front 50% when complete-type contract. Casey arrived spot-on at 8:00am yesterday morning and began doing his magic (the process involves boring 1/2" holes through the slab, then using high pressure and heat to inject a molten expanding foam under the slab.) The foam is rated to support about 5 tons (10,000 pounds) per pound of foam material, and....100 pounds later that whole slab is back to following the prescribed slope perfectly, raising almost three inches on the sunken side. He did a great job and was a great rep for the company, explaining what little was left to explain. He kept me up on the status of the (4-hour) job as he went along--because our slabs had previously cracked, he had to gently lift it up in small sections so as to not have the sections separate further. Perfect job. 24 hours later and the patched holes have dried to almost-invisible (see photos). Unless you know what you're looking for, you can't even really see that repairs were made. Now I just need to fill in the pre-existing cracks with concrete patching caulk and we're ready to schedule the hot tub delivery! Yippee! Thanks Terra Firma!
