Don Allen Plumbing is the most professional and ethical company in the world. I had a leaky facet and called for companies for quotes thinking I would need elaborate amount of work done. Justin was able to come over the same day while other companies give availability with the soonest days later! He took a look and was able to tighten some of the facet and stoped the leak and he didn't even charge me! What an amazing company if you ever need any plumbing contact Don Allen! read more

I just had Don Allen plumbing out to my 95 year old mother-in-laws home for a heater that would not come on. Turned out to be a fuse and some wires touching that needed to be cleaned up. While he was there she had him do a repair on a toilet the had been running. He was on time and very professional. I has shocked when he said that he was giving he a senior discount and that there would be no charge. Even if he had charged her I was impressed with them and I will be calling them for all of my plumbing and heating needs from now on. read more

Needed a plumber to consult on a bathroom project and this company really came through, above and beyond. Very fast at getting back to you and squeezing you into their schedule. Had an old PFister shower knob that needed replacing and they gave me the expensive and cheaper options. Really came through when I ordered the wrong part and got the job done after making an extra stop with one of their suppliers. I would give them ten stars if that was an option. Definitely would call them again for help with other plumbing issues. read more

Justin from Don Allen Plumbing came by today on short notice. He replaced the 30+ year old shut off valve on our main line, all of the old compression angle stops in the bathrooms, connected and preemptively fixed a bathroom sink (he volunteered to this extra bit). Additionally, he gave us some sound advice on not connecting some cheap hardware that was likely going to fail in the near future, and noted what to look out for next with our house's aging plumbing. He was great to work with, fast, didn't try to upsell anything, went beyond the initial job scope and, most importantly for us, was very reasonably priced. Other bigger plumbing outfits had bid well over 2x the price for the work Don Allen did and I'm sure they would have added on the additional expenses for the unforeseen stuff that came up. I'll be giving Don Allen a call for whatever our next plumbing need happens to be and we're very happy to have found our go-to plumber! read more

Like another reviewer mentioned, this business has been sold to South Bay Plumbing and Heating. I had a great experience with the original company, but not after the sell. I actually wasn't told the company had been sold and I wasn't dealing with the same team anymore when I called them again. It's hard to schedule work and they don't show up when they say they will for consultations. read more

Kim Allen has sold the business to Jay at So Bay Plumbing and Heating. Jay serviced an old floor heater professionally. It was very difficult to schedule the work, and he preferred to come at the last minute when he had time. Eventually, this pattern did not work for me, and we parted ways. read more

Kim and Roberto were a phenomenal team! We had a clogged kitchen sink and it took less than 15 minutes to unclog and he provided me with tips on how to avoid clogs. Definitely adding this to our service providers favorites for all our friends here in the south bay. It's so hard to find good trusting service providers. read more

After a number of plumbers come by and failed to fix my main line, Kim came by and provided a honest quote and actually fixed the problem. Highly recommended. read more

We have used Don Allen Plumbing for almost twenty years. First as renters, our landlord used them, and now as home owners we've continued to use their service. Kim always does professional work at a reasonable price. I see Yelp is stating that the business is "closed". I sure hope that's not true! read more

I have to echo another reviewer who commented that this was the most professional plumbing service in the world. I agree. Kim, the owner, came over and fixed a leaking pipe that another company had charged me for "repairing" when in fact it was still leaking. And he did it super quick. He gave me great advice on what to look for. This is a small local company, and they will give you the personalized service you won't easily find elsewhere. read more

This is the place! Call Kim and his crew for your next project or service needs.I had him do a complete copper re-pipe, relocation of laundry and bathroom drains, and a new natural gas service to my existing 3 bed/ 2 bath.Work was finished in a neat workman like manner that you would typically pay twice the amount for.Very competent and efficient company that only comes from generations of skilled plumbers! read more

I found Don Allen Plumbing today through a referral from some neighbors on the Nextdoor app. I called (our water heater had shut down over the weekend), and they called me back within two hours, came by, fixed what was wrong in less than 30min and our hot water was up and running again. It's this kind of promptness and kindness that creates customer loyalty, so I definitely recommend them. read more

Justin came by to replace an ordinary toilet flange. What should have been an easy fix, ended up being a complication due to the prior plumbing installation (not by Don Allen). The proper fix would cost me thousands that I was not willing to spend. Justin refused to install the new toilet flange because it would not be a proper fix. After doing my research Justin was correct. Although we didn't follow through with the fix, I appreciate the honesty. He didnt even take my 20 bucks for coming out. I hope this review brings you good karma. By the way, their quote was $100 cheaper than other well rated companies. read more

I called Don Allen Plumbing, because my sister recommended them and left a voice message as it was 6PM. Kim from Don Allen returned my call within 15 minutes and we scheduled an appointment for the next day. He came within the 2 hour window and quickly installed a new waste disposal. He was courteous, professional, and left our place clean. I'll gladly call him again with our next plumbing problem. read more

Needed urgent help with the shower tube leaking on 12/11 and called Don to make a reservation. On the next morning, Justin showed up on time and got on fixing it immediately. Experienced and efficient, Justin changed the old parts to stop leaking and cleaned the shower head to make the water flow powerfully and smoothly. After that, I told him that I also need to replace the food trash disposer in the kitchen. He checked his watch and said that he will hurry up and hope to finish everything in one hour to save labor fee for me. As he promised, he replaced a new disposer very fast and fix the hot water issue. He moved in and out within one hour and offered me a good discount. I would definitely call them in the future in case of any other plumbing issues. read more

Don Allen was referred by a friend...I Came Home from work today, the day before thanksgiving and my daughter informed me that our kitchen sink was backed up. My friend told me that Don Allen was always his first choice to call. He said that they were professional and fair priced. So I called right away, lucky me Kim just had finished a call near by and he was on his way. Talk about amazing timing for us. Any how Kim showed up in 10 mins and diagnosed the problem and had it fixed and finished in no time. We never had a preferred plumber before but now we will recommend Don Allen Plumbing to anyone! read more

Came on time , fixed the thermopile as per yelp quote , quick and professional . Provided 90 day warranty for the service and 1 year warranty for parts. What more can I ask . next time any plumbing, water heater issues Iam calling Kim. read more

We cannot say enough about this company! Our water heater burst and needed to be replaced ASAP. Roberto responded quickly and we had a new water heater less than 24 hours after discovering the leak. We highly recommend them! read more

I highly recommend Don Allen Plumbing and Heating. Kim and Roberto are knowledgeable, efficient and pleasant.

So glad we called Kim when our garbage disposal abruptly stopped working. He and his team came over right away and replaced it super quick! We've used them before, but I always forget to write reviews. They're so professional, affordable, and most of all, honest. I will never call another plumber aga read more

Professional, very responsive, super courteous, and willing to work with our schedule. For the service we received, price is very reasonable. We had them replace our faucets and shower hardware. They also came out to repair a gas line to our dryer same morning that we called. We will continue to use them and will recommend them to anyone who needs a plumber in the South Bay. read more

I highly recommend Don Allen Plumbing. Kim runs his business with a very high level of integrity and quality. Kim and his team did an amazing job transforming my existing worn bathroom with a broken jacuzzi tub starting to ooze mold to an amazing newly remodeled bathroom with a custom voice controlled capable walk-in shower. Kim let me know up front that this would be the first U by Moen Shower he's installed and there were no issues with the install and it works great. Kim and his team were professional during the entire project and were a pleasure to work with. Kim was thorough in his testing to ensure there were no leaks. When I had a leak coming from the attic the only thing I thought it could be was a leak from the shower. I called Kim and he mentioned the more likely culprit was the AC but he would come over and take a look just to make sure. Kim confirmed it was the AC and did not charge for the visit. The bathroom came out better than imagined. The reason I went with Don Allen Plumbing was because of their Yelp reviews and am glad I did. read more

See all

I had a major leak under my kitchen sink and was working with a different plumbing company than Don Allen Plumbing to fix the leak. The first company literally came out three times, had me replace the entire faucet and other items and still, the leak continued. I called Don Allen Plumbing and they came out in a few hours (Kim Allen). They immediately identified the problem that the other company had repeatedly missed and fixed it quickly. I am very happy with their expertise, professionalism and prompt respond and will for sure use them again. read more

I am so impressed with Don Allen Plumbing!!! My water heater broke and I contacted the original installation company to get it fixed. 3 days later the water heater was till not functioning, the part had not been located, and I was stuck taking freezing cold showers. I reached out to Don Allen Plumbing (my sister's recommendation) and within 12 hours - - - Kim helped me locate the part, get it delivered, and installed the new burner assembly. My water heater is good as new! Plus the bill was 25% of what the other company was charging! Professional, prompt, efficient. Great Plumbers!! read more
