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!

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.

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.
