Craftsmanship for Castle Pines Custom Homes

Mike quickly got to the problem and started work. He explained ever thoroughly and was fair and honest when discussing choices and costs. We will definitely be requesting Mime's services in the future.

I highly recommend Southside Plumbing. They are so professional and experts at what they do. Trevor was amazing to work with and fixed many plumbing issues that we had. His attention to every detail was amazing. I am so glad I found them and I will use them again in the future.

UPDATE 3/26: I needed the hose bibs (faucets) on the outside of my house replaced. Called Southside again and they were out in 2 days…Kyle and Adam had both bibs replaced and working again in less than 2 hours for a fair price. I will continue using Southside for all my plumbing issues!
I've needed Southside three times in the past two years...for a new water heater (they had the best price), a new shut off valve for my sprinklers, and most recently to fix a phantom noise in one of my toilets. After nearly three hours of troubleshooting, Kyle was able to find a small plastic/ceramic thing was stuck in the water line and remove it. Problem solved. Would use these guys again in a heartbeat.

Trevor and Zach were so friendly, patient and transparent about everything they did to help us with our gas leak situation. Safety was their priority and we appreciate them going the extra mile, even returning to our house when Xcel showed up and had questions about what was done. Thank you so much guys!

Adam and Kyle were great! They worked to identify the problem, gave a clear estimate at a reasonable price, and completed the work expertly. Southside was also easy and professional to deal with. Highly recommend this company in the Denver metro area!

Michael, Gabriel and Micha did a great job. We’re able to diagnose the problem quickly and get it taken care of. Communicated well throughout the entire process. Was glad to have the option to have them come on a weekend, even though I didn’t use that option. Were able to come the next business day, which is very much appreciated.

Mark was great! Easy to set up the appointment, Mark arrived in the window I was given and took care of everything in my concern. I will use Southside in the future!

Chris and Southside went above and beyond to source the necessary piece for repair and then ensured the job was done quickly and fully.

The Southside team was great. We discovered a leak under our kitchen sink leading to the dishwasher and Southside was able to fit us in same day. Trevor was great. After having some issues in the past with, less than qualified, techs we’d just find online…I would recommend the Southside team if you want it fixed right.

Trevor and Gabriel were very quick in answering our request on having our toilets. After examining all three of them, we were advised that they could be repaired but replacement was the better option . After Trevor patiently answered all our questions, we agreed and Heather called us later to make our appointment. Trevor and Adam came out on time and were very professional in their demeanors and finished the installations very effectively. There was no mess left and they carted off the old toilets. We are very happy with the work they performed. And we especially like the soft close lids and seats. We would highly recommend Southside Plumbing.

Mike was right on time for our service call. Very thorough and efficient. Kept a clean and organized work area. Kept us informed as he worked to solve our somewhat complicated plumbing problem. He was friendly and respectful in all of our conversations. We will definitely request Mike if we have any future plumbing problems.

We have used Southside Plumbing in the past with very good results. This experience was just as good if not better. We had a toilet replaced. Chris was very knowledgeable, honest, professional and efficient. He informed us of the different options and did a great job installing the toilet. We felt like we were in very good hands and would definitely use Chris and Southside Plumbing for future repairs and projects.

Southside plumbing has over the years proven to be the most reliable, professional experts who treated us with incredible care. Trevor, Adam, and Gabriel were absolutely fantastic. They brought our stress level down and our confidence level up. So grateful for this company. Heather took fantastic care and got us scheduled in minutes. From beginning to end this experience was seamless and felt like family!! Thank you

Really professional, Mike was awesome. He did a great job. He gave me his honest opinion of what he thought the problem was and he was bag on. They also offered us a 20$ off promotion discount if we donated food for the food bank. Clever marketing and it’s always nice to work with a company that wants to give back to the community. Will def be using them again next time we need plumbing services.

I had a great experience with Southside Plumbing! It began with Mark assessing my failing tank water heater and providing me options to prolong its life and options for replacement.
My wife and I decided on moving forward with a new Navien tankless water heater and a Halo whole house water filtration system.
Mark, Adam, Trevor, and Isaiah performed with excellence to remove the old tank and install the new systems all within a day.
We have been enjoying the improved water quality and endless hot water with the new systems.
I highly recommend trusting Southside Plumbing with all of your plumbing needs!
