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 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!

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.

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.

Service excellent but should have a senior discount to help those living on a fixed income. Price was higher then I expected for a job took a little over an hour.

Eli did a great job! Showed up right on time to give me a quote on a couple of different service options. Once I decided which option he was able to get the job done the same day. I was impressed with the fast professional service.

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.

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.

Great communication from start to finish. Technicians had the parts needed in their truck, worked quickly, and cleaned up after they completed the work. Will be asking them back to install a water purifier!

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!

Jared and Andrew were awesome. They explained in detailed what the process would be. Very attentive to detail. They cleaned up after themselves and worked non stop until the job was completed.

Matt and Randy were great. They finished replacing the hot water heater in record time. Matt and possibly Randy successfully completed an apprenticeship program through the plumber's union.
