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.

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.

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.

Great experience with In Demand Plumbing. Reached out to them for an issue i had late at night and they fit me in the next morning and promptly repaired my sink and toilet. Andre was professional and friendly and so was his working partner the second day. 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.

Thank you Elijah!

In demand plumbing, always amazes me with having knowledgeable, courteous, and friendly experts. I believe being a member has wonderful perks. I was able to get an appointment within one day. 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. Elijah offered affordable estimates to choose from and pricing that showed our discounts for being a member. Thank you, Elijah for doing a wonderful job!

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.

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!

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.
