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!

Needed a low water pressure bathroom faucet checked out. Made a appointment In-Demand. The service tech Zeek Salazar called me this morning stating he had earlier time available. I was thrilled to have it bumped up a few hours earlier. Zeek texted me when he was a few minutes away. Arrived and was courteous and very professional! We went over what was wrong and initially tried to troubleshoot the issue. After that didnt work he did a quick work order/estimate. Got the right part in a few minutes. Installed everything, cleaned up the work area before checking if any leaks and water was flowing smooth. Over-all another great expierance with In-Demand Plumbing as I have used there services before when I've had plumbing issues. Thank you to Zeek who came out today and made this a simple process!

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.

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.

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.

Jose showed right at noon as per the appointment. He was explaining what would be involved in the repair. After seeing the swollen hose bib pipe he continue to provide info on what could be a problem down the line. Fortunately there was only a need for a hose bib tower and he went to the van to put the estimate together. After a half hour we agreed to the repair price and within the hour Jose finished the job. The job was done well, quick and on time.

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.
