Drain lines can change direction under slabs, patios, and landscaping. Older homes may have undocumented tie-ins, abandoned runs, or mixed pipe materials, which complicate repairs. Without a verified map, projects take longer, demolition spreads, and the risk of damaging utilities or hardscapes increases.
Our process starts with verification. Licensed technicians use cameras, electronic tracers, and beacon sondes to confirm the location, route, and depth of your drains. With accurate data, we provide a safe, direct path for cleaning, repairs, or replacements.

If you experience any of these issues, it’s a good idea to schedule a professional drain location:
