I called In Demand to repair a water pipe leaking inside the walls. Zek contacted me via text to let me know about his arrival, showed up as promised and fixed the problem very promptly and professionally. He also had very helpful advice on what to do about water damage to the affected area. Overall a very pleasant experience and reasonable price. Thank you Zek!

Easy to make an appointment, office staff friendly. Got a text with a pic of who was coming before arrival. Technician showed up on time, was efficient, explained everything in easy to understand terms, respectful and friendly.
Replaced my sump pump same day, done quickly, reasonable price. Reviewed work with us and showed us it was working before he left. New pump works great, just in time for the rain.
Will definitely be my new go-to plumber.

Great experience with In Demand Plumbing. Reached out to them for an issue i had late at night and they fit me in the next morning and promptly repaired my sink and toilet. Andre was professional and friendly and so was his working partner the second day. Highly recommend.

I was so grateful that the technician, Elijah was able to come today to make the adjustments to the piping under my kitchen sink especially being that I just called requesting service yesterday!

Jesse was great. He replaced supply hoses and angle stops. He also troubleshooted another issue that came up with a bathtub valve, replacing it the same day. I've used In Demand multiple times and the interactions have always been great. Honestly though, Jesse is the best plumber from there that I've interacted with.

Thank you Elijah!

In demand plumbing, always amazes me with having knowledgeable, courteous, and friendly experts. I believe being a member has wonderful perks. I was able to get an appointment within one day. Elijah our technician was amazing. Elijah focused on resolving our issue and finding our leak. Once he found our leak, he took his time and made sure everything was working properly when he finished. Elijah offered affordable estimates to choose from and pricing that showed our discounts for being a member. Thank you, Elijah for doing a wonderful job!

Zeek arrived on schedule, quickly worked up an acceptable quote, removed the old water heater, and installed the new one with a minimum of noise, debris, or inconvenience. Really just a seamless and trouble-free experience. We have used In Demand for many years, and they always know what they're doing.

We had an emergency leak coming from
our attic causing damage to our ceiling. Our appointment was scheduled within couple of hours of calling and Elijah not only arrived on time but was also very professional and fixed everything for us within the same day. We would only recommend In Demand Plumbing!

Service was great. Beto was very attentive and was prompt to get the job done. Although I can't recall the name of second person who came with him, (Jay?) he was also very polite and did a great job installing my kitchen faucet. They both ensured all was cleaned up after the work was complete. Thank you both!

Ive had two great experiences with In-Demand Plumbing, first with Russell and more recently with Jesus.

Russell fixed a drainage issue quickly and explained everything clearly, while also being one of the most personable and professional service providers Ive ever met. Jesus impressed me just as muchhe immediately diagnosed my concern, took the time to walk me through it, and even offered helpful advice on other areas of my home.

Both were smart, kind, and thorough, showing that this company hires true professionals who care about their customers. In-Demand Plumbing has earned my trust and highest recommendation.

Andre was exceptional and thorough. What the insurance thought was a pipe leak, Andre ensured me it was not a plumbing issue. Definitely will hire again (Andre) on my upcoming remodel projects.

We had a bush removed in front of our house and saw the water shutoff valve was rusted and leaking. Russel arrived on time, gave us the quote and explained the scope of work to be done. Completed everything quickly and it looks and functions great!
