Homes in O Fallon, MO span a wide range of construction eras - and the plumbing inside them reflects that history. Older properties in established neighborhoods often have galvanized steel supply lines or cast iron drain systems that have reached or exceeded their expected service life. These aging systems develop corrosion-related pressure loss, chronic leaks, and drainage problems that require either targeted repairs or full re-pipe to resolve permanently.
Tree canopy is a part of what makes many O Fallon, MO neighborhoods desirable - but mature trees mean mature root systems, and root intrusion into older clay or cast iron sewer lines is among the most common and recurring drain problems our O Fallon, MO teams encounter. Hydro-jetting with camera inspection is the most effective way to clear it, understand the extent of the intrusion, and plan for long-term management.
Not every plumbing job in O Fallon, MO requires a permit - but many do, and it matters. Water heater replacements, re-pipe projects, sewer line replacements, and new fixture additions typically require permits in most O Fallon, MO jurisdictions. Pulling the proper permits isn't just a legal formality - it creates a documented record that the work was done correctly, which matters for insurance claims and for buyers during a real estate transaction.

Where pipe bursting is appropriate, we can replace the old line entirely while pulling the new one into place through the same path.
