I just reviewed my invoice and found out I was being charged $287 for a sink strainer from their company but I provided the sink strainer in purchased to the plumber and all the additional drain tubing and P trap using none of In Demand plumbing parts prior to the installation. My drain strainer was around $20 stainless steel from Home Depot that the plumber installed. I'm requesting a refund on the strainer that has already been charged on my credit card.

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!

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.

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.

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.
