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!

Woke up Monday morning to a broken water main with a river going down my driveway. I reached out to In Demand, Jeff immediately responded and got me scheduled for that day. Andre came out (arriving early), quickly diagnosed the problem and fixed the break in the main. It was a deep break that took a while to get to, but they stayed late and finished the work in the dark, got our water back on same day. Great customer service, great communication, and great work. Highly recommend.

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.

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.

Elijah did a wonderful job installing our new beverage faucet to our RO. We had a primary room faucet that needed replacing an it was very tough to get out. Elijah kept all the areas he was working in very neat a tidy. He also took a look at our shower that wasnt producing enough hot water. He walked through our needs and gave us a price that was reasonable. I would recommend Elijah an In Demand Plumbing to all my friends 100%. They will be my first call for all my future plumbing needs.

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!

Vince and Julio were totally professional, courteous, and fast! I also really appreciated Vince's willingness to thoroughly explain every step of the process as well as having no problem answering any of my questions throughout the repair process. I really couldn't ask for a better repair experience.

I had a great experience with Jos and Martin today installing my Moen, Pressure Regulator, Earthquake Valve, and flushed my water heater. I would recommend them to anyone who needs work done. They were very professional and took the time to explain to me how everything worked so I could understand. It was extremely helpful and I'm thankful for their great service!

Service was exceptional, the problems got resolved fast and the advice was good. I had my own preconceived ideas but once the technician got working on the problem and showed me what was happening, it made sense. I was so pleased how patient the technician was and how professional he was in explaining.
