Recommended Customer Reviews

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.

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.

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.

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!!

Don Allen Plumbing Is excellent.. He knows his business, came over very quick and fixed our water heater and also put everything up to code! big bonus. He is reasonable priced and we will call him for all our plumbing needs..

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!

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.

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.

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!

Courteous, very kind, and helpful on the phone. Bent over backwards with my schedule to schedule appointment.
