I have had two service calls now from Southport. Both times the servicemen were prompt and knowledgeable. Last evening I had called because I had a backup with my basement drain. I thought I could wait until Monday but when it backed up again, Thursday night, I called and they rescheduled me for an early morning appointment. Blake arrived and kept me informed of everything he was doing and what he was finding. He made sure to speak with his superior Throughout his time here.Even though it appears the drain was clear they stayed and made sure that I had no issues with the basement drain. Anytime I have had any questions or concerns the owner, Jackson has always addressed them
Promptly and assures, his customers are satisfied! I have been very happy with Southport

After our home inspection flagged some plumbing issues, I contacted Southport Plumbing. From the very first phone call through the quote and final completion of the work, everything was handled professionally and smoothly.
Their customer service was fantastic — friendly, responsive, and helpful every step of the way. The plumber (Joe) who came out kept me fully informed throughout the process, which I really appreciated. There were no surprises or hidden costs; the final price matched the quote exactly.
They also left the worksite clean and tidy when they finished. Overall, a reliable, transparent, and high-quality service. I would definitely recommend Southport Plumbing and would use them again without hesitation

Southport Home Services is a great company and a great choice to take care of your HVAC needs. Although we have dealt with a couple of the other local service companies, we were lucky to come across Southport when we were ready to replace our furnace and AC. They made good, solid, recommendations, suggested going with a heat pump, and did NOT try to upsell us on more than we needed.
Jackson Barrow and the installation team were fantastic to work with; knowledgeable, patient, willing to explain and educate as they did their work. They fixed some issues with the previous system's infrastructure and made sure we were well taken care of. When we had a minor issue (no fault of Southport) Jackson and team came back out prompltly and took care of it, despite our request being a bit of extra work for them.
I really can't recommend them highly enough!

We had an excellent experience with Caleb. He was professional, knowledgeable, thorough, and extremely helpful from start to finish. He took the time to explain everything clearly, answered all of our questions, and made sure we understood what was going on, and what our options were.
What really stood out was Caleb’s attention to detail and the pride he takes in his work. He was friendly, respectful of our home, and never made us feel rushed or pressured. It’s refreshing to work with someone who generally cares about doing the job right and providing great customer service.
We couldn’t have been happier with the service Caleb provided, and would absolutely recommend him and Southport, plumbing, heating and cooling. Thank you, Caleb, for the outstanding service!
