Addressing Common Utility Challenges in Decatur

Decatur’s infrastructure and environment present unique challenges for property owners. At TCI, we provide solutions tailored to these local issues.

  • Sewer Backups & Line Responsibility: Heavy rainfall can cause backups. While the city handles the main lines, property owners are responsible for their private laterals. We use video camera inspections to diagnose blockages from tree roots or debris on your line and provide expert repairs.
  • Lead Service Lines & Water Pressure: Older homes in Decatur may have lead service lines, which are slated for replacement under state law. We are experienced in working with older plumbing and can also address low water pressure issues caused by corrosion in aging galvanized pipes.
  • Water Conservation & Drought Awareness: With Lake Decatur’s water levels impacted by past droughts, water conservation is key. Our efficient irrigation systems are designed to minimize waste. We also perform required annual backflow preventer inspections to protect the municipal water supply.

Testimonials from Our Customers

TCI Companies is proud to say we have a list of happy customers who we’ve helped during our decades in business. Here’s what a couple of customers had to say about their experience with us:

“Upon Brett’s arrival he was very professional and courteous, cleaned up after his job was completed. I had a little clog issue in an old pipe that he was connecting new lines and faucets on that would not let water pressure out, and he went above and beyond to make sure I was satisfied with his service. When I need you folks again I will ask for Brett—it’s hard to find dedication these days. Thank you, Brett.”

— Mike Y.

“I had a main water line leak. I called TCI and they were at my house within 2 days (it would have been 1 day if not for heavy rains.) They worked for 6 hours locating my main water line, digging down to it, and replacing it with a new pipe. They came back the next morning and finished filling in the trench. I would highly recommend TCI to anyone needing any plumbing work. They were responsive, professional, courteous, and extremely knowledgeable. Great job!”

— Bill U.

That kind of workmanship and integrity is what we bring to every job in Decatur — regardless of scale.
