I wish I could give Oscar 10 stars. I can’t say enough about how amazing my experience was. Having an issue you weren’t expecting happen is stressful. But, Oscar made this experience easier and less stressful. He explained everything to us and gave us options. I didn’t feel obligated to choose him. He let his knowledge speak for itself. His work was amazing and he fixed everything the same day. We spoke with a few plumbers and Oscar was and is the best choice. I will be recommending him to everyone that asks for recommendations for a plumber.

Oscar came out to replace my kitchen faucet and did an excellent job from start to finish—he arrived on time, worked efficiently, and installed the new faucet perfectly with no leaks or issues. He was professional, respectful of my home, and left the workspace clean when he was done.

My wife called Oscar on a Saturday (3/21/26) around noon. She requested an estimate for a drinking water filter system and faucet installation. After she sent him pictures of the kitchen sink and underneath, he gave a quote within 10 minutes. We approved and he came down to install it same day, around 1:30 PM. He finished the job in about 2 hours; he even quoted and replaced our old angle stops in that timeframe. Overall, we're very satisfied with his work. Positives: -Provides high quality materials and top notch work. -Leaves work area very neat and clean. -Very approachable, answers all questions amicably. -Pricing is reasonable. -Offers multiple payment options; cash, check, credit card, Venmo, Zelle. Negatives: -None.

I had an outstanding experience with Oscar from OA Plumbing LLC. From the very beginning, he was incredibly responsive, professional, and thorough. What really stood out was how clearly he explained everything—he walked me through all possible scenarios and was completely upfront about pricing, which I really appreciated. What makes this experience even more meaningful is that I had earlier in the day dealt with another company that was clearly trying to upsell and take advantage of the situation tripling original quote in a matter of 30seconds, I didn’t share any of that with Oscar, yet he still approached everything with complete honesty and integrity. That alone says a lot about his character and the way he runs his business. He went above and beyond by doing a full video inspection of the plumbing system at no charge, checking all faucets, drains, and toilets to make sure everything was functioning properly. He was extremely thorough and communicated with me every step of the way. Yes, it may have cost me more bringing in two companies vs calling OA from the beginning but when you know something isn’t right, it’s worth it to stand on integrity. Oscar proved that there are still honest professionals out there. Because of this experience, he’s earned a repeat customer for as long as I’m in Vegas, and I’ll be referring him every chance I get. Truly grateful for his time, his honesty, and the way he does business. 5 stars all the way.

Our garbage disposal went out and Oscar came in installed a new one. He provided information to maintain it in good condition for a long period.
