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.

I booked an online appointment with In Demand Plumbing to check out an outdoor pipe that was leaking. I was able to get same day appointment and have it fixed right then. Our service technician was Vince, who was very knowledgeable, friendly, and professional. He called to let me know he was on his way, once he was here, he assessed the problem and explained what was going on. He answered all my questions and then got to work. Vince kept my husband informed throughout the process of fixing the issue. Him and his team member Gio did an excellent job! We will definitely call In Demand Plumbing for any future plumbing work/repairs needed. I highly recommend Vince and In Demand Plumbing for any plumbing work you need!

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.

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!

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.

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.
