I had my water and ggas lines replaced on a historical house in downtown Concord. I found the workers to be pleasant, and professional at their tasks. They communicated their plan for repairs and stayed to the agreement. I will use them again for future jobs.

What a surprise and blessing. Two days after the job was completed, I received a call from the project manager, who explained he spoke with his team and decided that a larger gauged piping should have been used on the project and that the company would be replacing it at no cost. Wow. On Monday they came and dug out the entire length of the original work and replaced the perfectly good piping and replaced it with what he described as the best piping for the project.

One word describes the men of this company, integrity. Thank you for your honesty and great work. I 100 percent recommend them and will use them again.

They did an excellent job on a new tankless system. I used them again to install new traps to my new vanity top. Daniel did both jobs. Very nice and knowledgeable employee. Definitely will use them again because of Daniel.

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!

It was a weird problem. In the end, the water meter was lying. Although the tech did not find the issue, not his fault, he was very thorough. I knew what wasn't wrong, which was extremely helpful. No problems recommending this company.

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!

Elijah our technician was amazing. Elijah focused on resolving our issue and finding our leak. Once he found our leak, he took his time and made sure everything was working properly when he finished.

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!
