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.

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.

It was very easy to schedule the free inspection and got the quote. The price was competitive and Andres was thorough in explaining the work which was required for the fix. Will definitely recommend and will be using them in future for all plumbing needs.

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!

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.

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.

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!

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.

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.
