Recommended Customer Reviews

IPlumb arrived quickly, and figured out the right parts to fix my misstated u-tube underneath a sink.
The fix was awesome and my washbasin never clogged again (now over 2 years out).

Highly recommend! I plumb was prompt and professional. The price was fair, and I really appreciated Steve's quick responses and great work!

I can't even being to express how thankful we are for Steve and Spencer. We had a slow leak in a 2nd floor interior wall plumbing pipe that was running down to our wet bar below. After we ripped out our tile & dry wall, Steve and Spencer came out and fixed the botched plumbing job an inferior plumber had done a dozen years ago. We couldn't be happier. Steve did extensive plumbing work at our 2nd home a couple years back so when we knew we had big trouble, we called him because we trust him. He also recommend an amazing tile contractor to completely retile our bathroom after their repair. They are the real deal and take great pride in their work. If you want something done the right way, call iPlumb. Don't give it a second thought. Thanks Steve and Spencer!

They fixed the shower head in my bathroom and were very helpful and friendly I recommend calling them anytime you have any issues. My showers are so much better quality of life improvement

When shit goes down (or rather, when it doesn't) don't throw a shit fit. Call I Plumb! Look, shit happens. We all need someone to rely on when we find ourselves in a shitty situation. You should NOT have to deal with your shit alone. With a toilet on the fritz and a clogged sink, I was swimming in shit; it was a shit storm at my house, category 5. I tried to fix it myself but was clearly out of my element like Donny; shit out of luck. Then, my dad recommended I Plumb and they responded to shit quickly! They got shit done. No cap, no crap. The plumber who helped me was amiable, transparent, and considerate as he went in and out of my home. I unfortunately got stuck on back-to-back bullshit business calls. While he worked, I had to listen to a client throw a shit fit However, with I Plumb, there was no crap to cut, and that was such a relief!
In short, I Plumb fixed both of my issues efficiently. They are THE shit. I would recommend them without hesitation and will certainly call on I Plumb again should I find myself ( not) in a shitload of trouble.

Great experience with I Plumb! Problem was addressed in 25 mins.
Very happy with their service.

I wanted my main water shut off valve moved to a different location along the pipe. I contacted them on their website and sent a photo to their phone number. Got a quote in 1-2 days. Steve recommended replacing the old pressure regulator, and 2 old valves at the same time and quoted around $700. That's a good quote. It was roughly the same quote I had received a few years ago (no inflation?!) from another small plumbing company that moved out of the area. They had time the next day. Quality of work was very good. I think the name of the person who did the work was Spencer.
At the start of the job Steve came and observed that there were some challenges that he did not see in the photos I had sent. The pipes were too close to the house wall. The stucco was added after the pipes were in place. They had use pipe elbows to route the section of the pipe away from the wall to accommodate the new pressure regulator. Another thing that Spencer later told me was that they had arrived with parts for 3/4"" pipe, but I had 1"" pipe. So Steve had to go to the store to get parts. These issues were mentioned to me only for my information. They did not whine about the extra work, bigger parts or ask to increase the cost.
A few things Spencer tried didn't work out due to the limited length of the pipe and the closeness to the stucco. The final solution he came up with looks very elegant. He took his time (almost 3 hours) to do it right and explain things to me. This was far from a rush job to get on to the next job.
He said it was a 4 person company.

Spencer came out to replace my kitchen faucet and it was really quick and he did a great job. I had gotten a quotes from others and I Plumb was reasonably priced. Would use them again!

Steve seems friendly and personable initially but his persistent refusals allowing his contractor's info mandated on many needed official docs and inflexibilities plus unwillingness to work with us did trouble us! We had a big project and needed much flexibility to meet our plans and project's goals per our intents properly. Sadly, Steve was not willing to support us.
We will not recommend Steve and there are many other better plumbers available out there, frankly, that's what we did and were happy we did not use Steve.

Perfect for small businesses. Swift services. Will use again!
I am building out a Coffee Cart, but the water lines I had weren't compatible with my equipment. I used I Plumb Inc's online booking services, and had an appointment booked and confirmed for the next day (I'd recommend uploading photos to their site and calling them when booking).
