Sewer camera inspections are needed because the inside of a buried pipe is completely invisible without them — and sewer line problems develop and worsen underground long before they produce symptoms inside the home. By the time a homeowner notices gurgling drains, repeated backups, or sewage odors, the underlying condition has usually been building for months or years. A camera inspection gives you an accurate picture of what is actually happening inside the pipe: root intrusion at specific joints, grease accumulation narrowing the diameter, cracked or offset sections caused by soil movement, or a pipe that is in excellent condition and needs no action at all. For most homeowners, an inspection every two to three years is a reasonable baseline — more frequent for older pipes or lines with a history of root problems.

Why Symptoms Alone Are Not Enough

A slow drain or occasional backup tells you something is wrong but not what. Clearing a line without a camera inspection first means treating a symptom without knowing the cause — which is why drain problems often recur after a standard snaking. A root mass that gets punched through with a cable auger will grow back. Grease coating that causes repeated sluggishness does not get addressed by a snake at all. A cracked section that allows soil infiltration will keep causing problems regardless of how many times the line is cleaned. The camera inspection is what turns a reactive repair into an informed one.

Situations That Specifically Call for a Camera Inspection

  • Buying a home — especially one built before 1980. Older homes may have clay tile, cast iron, or Orangeburg sewer lines that are near or past end of service life. A camera inspection before closing gives you a clear picture of what you are inheriting.
  • After a root clearing — to confirm the roots were fully removed and to document the pipe condition for comparison at the next inspection.
  • Before adding a bathroom or ADU — to confirm the existing lateral can handle the increased load and is in good enough condition to last the life of the addition.
  • Recurring slow drains or backups — when the problem keeps coming back after cleaning, a camera inspection finds the cause.
  • Wet or sunken areas in the yard above the sewer line — a potential sign of a leak or broken section that needs to be confirmed and located before repair.
  • Persistent sewer odors inside or outside the home when drains appear to be functioning.

How Often Should Inspections Be Scheduled?

Every two to three years is a reasonable starting point for most homes. The right interval depends on your specific situation. Homes with clay tile or cast iron laterals in established Front Range neighborhoods — where mature trees are common and expansive clay soil shifts every year — benefit from annual or biennial inspections, because root intrusion and joint movement are ongoing processes, not one-time events. Homes with newer PVC laterals and no history of root problems can generally stretch to every three to five years. If roots have been found and cleared before, annual inspections let you catch re-growth before it develops back into a full blockage.

Colorado Factors That Make Regular Inspection Worthwhile

The Denver Front Range has several conditions that make sewer line health worth monitoring proactively. Expansive clay soils shift with seasonal moisture changes, stressing pipe joints and causing gradual misalignment over time. Many established neighborhoods — Wash Park, Congress Park, Park Hill, Wheat Ridge, Littleton, and others — have homes with 50- to 80-year-old clay tile or cast iron laterals under mature trees whose roots have had decades to find pipe joints. Hard water deposits mineral scale inside pipes over time. And the combination of cold snap freeze risk and heavy spring snowmelt creates moisture extremes that affect soil stability around buried infrastructure. A regular inspection cadence catches developing problems in these conditions before they escalate.

Catching a developing sewer issue early is almost always less disruptive and less expensive than dealing with a full backup or line failure.
