I found Plumbing 101 on the Nextdoor app. Nathan Corona had the most reviews out of all the plumber recommendations and is highly rated. He also has 5 star reviews on Yelp. I had to use his services on several occasions in 2023. Each time he responded promptly and was able to give me a quote over the phone when I provided a video of the situation. It's good to know the cost in advance so there's no surprises. He said he doesn't advertise because he has a lot of business through word of mouth, which is a very good sign.
The first call was regarding the on/off handle in the guest shower, which he promptly replaced, as it was the original handle when this house was built. While he was here, I showed him my bathroom faucet had a slight leak. He told me that Moen has a lifetime guarantee, which I wasn't aware of. Since I had the receipt and took a video of the leak, Moen sent me a brand new faucet. I haven't had to use the new one yet because he fixed it, but I'm glad he told me about the lifetime guarantee. Also, my kitchen faucet was losing water pressure, so I sent him the video. He told me it probably just needs the faucet head cleaning due to sediment build up, so I cleaned it and it worked. That saved me the cost of having him come out to clean it.
Nathan is very personable, knowledgeable, trustworthy and I can say he definitely stands behind his work.

We had a sink leak. We hired one plumber who wanted to charge us $2k, but my husband threw him out without negotiating the price.

Nathan, is very kind, helpful, respectful, professional. His work is literally like an In-n-Out Burger service. Nathan; was in and then out, very quickly.

Nathan at Plumbing 101 did a great job, and I am pleased with his work. We have them on speed dial for any issues.

Called Nathan, explained that I needed my water heater replaced. He gave me some tips on buying a new one. I bought a new one, had it delivered and texted him afterwards. He was able to come out at 8am the next morning and had the new one in and running quickly. He also took the old one away for a nominal fee. He is super nice, professional, and affordable. Very happy with his work and would recommend him to anyone!

I gave Nathan a call about a rental with a leak and he responded quickly. Actually, he answered the call and had someone out there the next day and took care of the situation quickly! I will definitely be going to him for all our plumbing needs. Thank you Nathan!

Have used Nathan for plumbing for about 2 years now and have always been very happy with his work. Always clear as to the work that he's going to do and why. Have used him multiple times in two different properties to replace shut off valves, new water spigots, sink repairs, repairing pinhole leaks etc. Always been reliable and fair with his pricing. Well, after a second pinhole leak at our primary home we went with Nathan's recommendation to repipe the house with PEX. He brought an entire crew and did our almost 3000 square foot home with two stories and 3 full bathrooms, and an island with a sink in about 5-6 hours. Yes, they have to open up holes in the drywall, and quite a bit to make sure it's done right, but I am very happy with the outcome and will have peace of mind as once they opened up walls, some pipes looked like they were about to go at any time! We have a rental property that already has had one leak and we're going to schedule Nathan to do the PEX repiping at that property as well. Do not hesitate to call Nathan. He seems to do it all and do it right.

Nathan came by to fix my toilet, he was recommended and I can see why. He's very friendly, professional and knowledgeable. I felt at ease knowing he was honest about the work that would be needed, and his prices are reasonable. I highly recommend him.

We called Nathan on a Sunday with our washing machine's hot and cold valves corroded. This was discovered when trying to install a new washer. Unfortunately, Nathan was out sick and was unable to come fix the problem, as he didn't want transmit his illness. So, he sent one of his trusted colleagues, Ignacio, and was able to remove and solder in new valves successfully. Ignacio was professional, efficient and tidy. Nathan called after the job was completed to make sure all was satisfactory and thanked us for reaching out to him. We appreciate him and Ignacio for helping us out last minute on a Sunday. We wouldn't hesitate to call him for future plumbing issues/needs.

After seeing so many great reviews and comments about Nathan from Nextdoor app surrounding neighborhood. Nathan availability, knowledge and fees are reasonable. He repaired my toliet and replaced garbage disposal. He found a water leak under my sink and was quick to repair and referred me to another great company Out Dry Medics. Nathan and Out Dry Medics will definitely get referred to family and friends.
