We have used Dallman plumbing for several projects over the last 4 years. They have been responsive and helpful. Three projects went perfectly. The most recent project had problem that led to some leaking when a valve was turned on about 8 months later. They came back and fixed the problem right away for no charge and told me they stood by their work. We have had Rick and Curtis both come out and both were professional and great.

Dallman Plumbing (Curtis) recently installed a new water heater in our home. Communication and service was excellent. Will certainly be calling them for any plumbing needs.

My sump pump stopped working, leading to my basement starting to flood (old, leaky basement). I called Dallman and somebody came to fix the problem in just a few hours. I appreciated the quick response, and the people were friendly and professional. I highly recommend Dallman Plumbing. Service: Sump pump installation

I asked for a quote for a fix of a toilet installation gone awry. Mike, the owner got back to me very quickly and set some realistic expectations. He sent Curtis in to do the job and Curtis was a pleasure to have in my house, very professional, and did the job well and thoroughly. I will be going to these folks for all of my future plumbing needs.

DP completed my master bath addition project several years ago (which we were very pleased with). I recently contacted DP to obtain an estimate for installing a utility sink in my basement. Mike W. (a/k/a Big Mike) came out the same day that I called to take a look at the scope of the job. He explained what needed to be done, provided an estimate of the cost and even offered to start the work that day!

The next day, Curtis arrived to complete the job that Mike started the day before. Both Mike W. and Curtis were friendly, efficient and they do great work at an affordable price. I will definitely be using them again for any future plumbing projects.

My outside faucet was broken, perpetually leaking. I reached out to Dallman Plumbing and they replied right away. We scheduled a technician to come out within a day and my problem was solved. Efficient. Professional. Personable. Knowledgeable. I will recommend them to all in need of excellent service. And, oh by the way, they actually follow up to check if things are going ok. Awesome Service!

It was such a pleasure doing business with a company like this one where they are professional but friendly as well. prices are very good they are not out to rob you and they do great work. Curtis came to our home to uninstall and get all our plumbing ready for our new Countertops being installed then came back to hook everything up with the Countertop Installers. he was friendly down to earth and knew what he was doing. I would highly recommend this business.

I called Dallman Plumbing for a quote on a kitchen remodel. Instead of sending someone over, I was asked to take pictures of the plumbing under the sink and email them. After 2 weeks with no response, I went with a plumber who came to the house to do the quote. The project is complete now, and I never did receive a response from Dallman by email or phone.

Dallman has become my go-to plumber. They truly put the customer first, right from the start. They don't hesitate to recommend other options if they can't meet your timeline. Very professional and courteous group.

Dallman plumbing helped us install our new dishwasher. Service from start to finish was outstanding! They talked to us about what we needed done and viewed pictures of our unique situation. Rick was professional, through, and got our dishwasher in! Very satisfied customer we know who to call for future plumbing needs.

I don't know a thing about plumbing. The guys at Dallman were wonderful to work with, helping explain things to me. It's nice to know who to call for plumbing work for now on.

We've had Dallman out twice in the last month, once to install a faucet and plumb a new sink and then again to address some defects they noticed with our dishwasher install (no air gap.) Easy to schedule and communicate with, and both times the final bill was right in line with what had been discussed. Fast and friendly as well when in our home. Highly recommended.

I recently needed to have two new faucets replaced in my vanity. I had previous experience with Dallman Plumbing. They replaced my water softener. My experience with getting the faucets replaced could not have gone smoother. The staff at Dallman worked with me online to select the new faucets. This made it very convenient for my schedule. On the day of the installation, the Plumber arrived on-time.

During the procedure he was always respectful of the space and careful not to create a mess. The expense met my budget guidelines. I would highly recommend this company for any plumbing needs.

Dallman Plumbing did the plumbing for a bathroom remodel and replaced our water heater. They were great all around. They showed up early, finished on time and were kind and courteous. A+ all around.
