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.













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!
FAQs for Littleton, CO Homeowners
Galvanized pipes corrode from the inside out over time, leading to reduced water pressure, discolored water, and eventually leaks. If your home was built before the 1970s and still has galvanized plumbing, a whole-home repipe is often the best long-term investment. Our team can assess your pipes and recommend the most cost-effective approach.
Yes. We understand that unexpected plumbing repairs can strain your budget. We offer financing options to help you take care of your home without financial stress. Ask us about available plans when we provide your upfront price.
Hard water is common in the Denver metro area and can cause mineral buildup inside pipes, reduce the efficiency of your water heater, leave deposits on fixtures, and shorten the lifespan of appliances.
