Plumbing reviews in Thornton, Colorado

Always friendly and professional. I have been using them for over a decade and wouldn't suggest any other plumber.

I had work done including hot water heater replacement, they were a pleasure to deal with - reasonably priced, professional, experienced, nice, everything!

When they say fast they mean fast, wow I was really impressed start to finish. Professional and curtuous, they just dove right in fixing my problem in less that 30 minutes and they charged less than half of what another plumber quoted me. I would highly recommend these guys to anyone.

Seriously impressed! From start to finish, Kevin, Tonya, and Gavin were a pleasure to work with. Fixed our leaky tub spout in a matter of minutes and for a reasonable price. I will absolutely have them back for other plumbing work.

Excellent plumbing company. Replaced 2 sump pumps and several other plumbing jobs. Very friendly! Highly recommend.

I googled a plumber near my house and found this company. They were actually just across the street from me and I liked that they were home based. I called asking for help with a new dishwasher install and the woman was so so helpful! She didn't try to sell me any services and suggested things I should try myself before they came out. I did end up having to call them out anyway to reroute the copper piping from the wall because I couldn't do that part myself. They didn't over charge, came out immediately and did an amazing job. Steadfast is my new go-to plumber!

As a single woman getting any sort of service provider in my home is a bit nerve wracking. Kevin and Tonya were fantastic, immediately putting me at ease and getting right to work. They were early, did the work fast, and provided a quote on future work that is very reasonable. So happy to have a trusted plumber in my contact list now!

Steadfast Plumbing installed my new hot water heater quickly and efficiently! They were on time, very friendly and neat. Tonya completed all of my Xcel Energy paperwork so I could receive my rebates quickly and explained everything to me, including the new settings on the hot water heater. Would definitely recommend Steadfast to anyone!

I used Steadfast Plumbing to find a leak, install a sink and faucet (which required some new plumbing) and to install a water hammer arrestor on an outside irrigation system. They arrived the first day to look at the leak and figure out what would be needed for the other jobs. They were prompt, quickly figured out the source of the leak, and looked at the other jobs. They came back a second time to do the sink install and the irrigation system, again arriving on time, and finishing the work quickly and professionally. The cost was more than reasonable. I would not hesitate for a second to use Steadfast again, and would highly recommend them to anyone else looking for a plumber.

After dealing with other plumbing companies around Denver, whom drive around in their fleet of trucks. I have found out who is paying for those trucks and advertising. The person paying for those things is the customer. I had a drain trap replaced by Brothers Plumbing and the charged me $180 for a small piece of pipe and installation. With Steadfast, they don't charge crazy rates and it doesn't take a two week appointment before they come out to complete the job. Steadfast is my go to plumbing company everytime!

Steadfast Plumbing arrived on time, did an excellent job replacing our water tank within 1.5 hours, cleaned up, explained the permit paperwork and heater operations. We highly recommend them for any issues you need.

Kevin and Tonya do excellent work at reasonable prices! It can be hard to let any contractor in your home and trust that they are charging you appropriately, however I feel very comfortable with Steadfast, their assessments and their pricing. They're also very nice and professional, they arrive on time and leave your home clean.

I was very impressed when I left them a message after 8pm on a Thursday night and they called me back within minutes. I told them I didn't expect a call back until at least the next day but Tonya assured me that whenever someone has a leak, they take it very seriously and want to help! They came out to take a look, found that the leak was a manufacturer defect in the faucet (not their fault in any way), and graciously walked me through how to handle the return/exchange with the retailer as well as set up a time to come back and install it for us.

After working down the list of plumbers on NextDoor, after a pipe burst today, with no luck, I called Steadfast who were able to schedule us the same day. Pipe repaired inside of 40 minutes! You have no idea how thankful we were, even more so with the price! I was expecting well over $600 but it surprisingly affordable. Wonderfully kind folks. They will be our go to company.

We have been using Steadfast Plumbing for years and will continue to do so! They are such nice, professional people. Our latest issue was that our shower stopped working yesterday just before 5 pm. I called and spoke with Tonya, texted her pictures of the shower, and Kevin was at our house and fixed the problem today by 1:30 pm. Such amazing service! Thank you!

Steadfast installed my new water heater back in 2019 and they also repaired a leaky ABS drain pipe for me. They are professional, courteous, and their prices are reasonable. I had the pleasure of meeting both Tonya and Kevin and they are the nicest folks. This is the type of "local business" that people should support, and they have earned a lifelong customer in me.

I hope you won't need them for anything emergent, but if you find yourself needing an excellent plumbing company, I want to give a full endorsement of Steadfast Plumbing. We've used them for a few jobs, the most recent being today. We returned home from vacation yesterday to find our hot water tank had been leaking for days. I called at 4:15 pm, Tanya got back to me that evening, and this morning, she had a quote ready. She and Kevin were at our house with a new tank at noon and done at 1pm. (They also moved some things around to make everything more accessible). They are lovely folks and do an excellent job.

I called Steadfast Plumbing yesterday for a slow leak, not an emergency. They were able to get me in today, and came right on schedule. They were kind and professional, reasonably priced, and very fast. I have copper pipes and will definitely need a plumber again. When I do, I will be calling these nice folks.

I had a cracked pipe that needed replaced. I shopped some larger plumbing companies who wanted to tear out and redo everything for thousands of dollars. I called Steadfast Plumbing and Tonya listened to what I needed, I sent photos, and she was able to give me a guesstimate on the repair. Kevin came out a week later and fixed what needed to be fixed in under an hour and at an incredibly reasonable price. Very nice people, good mom and pop business. I’ll be keeping them in my Rolodex.

Steadfast Plumbing replaced our water softener in Oct 2023 and replaced our water heater in June 2024. Professional, experienced, courteous local business that provides high quality work at a reasonable price. Great communication. We appreciated the same-day response to evaluate our leaking water heater and discuss our options. Highly recommend!!

Called steadfast after trying and failing to install a new sink and disposal. (Rough drain line in wall was higher than the disposal outlet, did not allow gravity flow) Steadfast came out one day after calling them at 7:00 on the dot as scheduled. Technician was pleasant and understood the problem after asking several questions. Price was reasonable and not a money grab, standard time and material charge. Kept area clean and got me a working sink and dishwasher, extremely pleased with the company, highly recommend.

Awesome service and David is reasonable and knowledgeable. Highly impressed!!
