For most Denver-area homes, a sewer camera inspection every three to five years is a reasonable baseline — but the right interval depends on your home’s age, pipe material, tree coverage, and whether you’ve had drain problems in the past. Older homes and those with mature trees overhead often benefit from annual or biennial inspections to catch root intrusion before it becomes a backup.

Why Denver Homes Need More Frequent Inspections Than Average

The Front Range has a few characteristics that accelerate sewer line wear. Denver’s expansive clay soils move seasonally — swelling when wet, contracting when dry — which causes pipes to shift, crack, and offset at joints over time. Many neighborhoods in Denver, Aurora, Lakewood, and surrounding areas still have original clay tile or cast-iron drain lines from homes built in the 1950s through the 1970s. These materials are well past their design life in many cases. Add to that the large, established trees common in older Denver neighborhoods — cottonwoods and silver maples in particular send roots aggressively into sewer lines in search of water — and you have conditions where problems can develop faster than homeowners expect.

Situations That Should Trigger an Inspection Now

Even if it hasn’t been three years since your last inspection, certain conditions warrant scheduling one right away. Slow drains throughout the house — not just one fixture — often point to a partial blockage or root mass in the main sewer line. A gurgling toilet, especially when water drains elsewhere in the house, is a pressure warning sign. If you’ve had a sewer backup or noticed sewage odors in the basement or yard, don’t wait. Similarly, if you’re purchasing a home and the inspection report didn’t include a dedicated sewer scope, ordering one before closing is one of the best investments you can make — sewer line replacement is one of the most expensive surprises a new homeowner can face.

What the Camera Inspection Shows

A sewer camera inspection sends a waterproof camera on a flexible cable through your cleanout and down the main sewer line to the city connection. The technician watches a live feed and records the footage, logging the location, type, and severity of any issues found. Common findings in Denver homes include root intrusion at clay tile joints, scale buildup from the area’s notoriously hard water, cracked or offset sections caused by soil movement, and grease accumulation in the line from the kitchen. You receive a clear explanation of what was found, what it means, and what — if anything — needs to be done about it.

Preventive Cleaning Paired With Inspection

Many homeowners pair the camera inspection with a professional drain cleaning — specifically hydrojetting, which uses high-pressure water to clear roots, scale, and grease buildup before they cause a backup. This combination gives you both a clear view of the pipe’s condition and a clean starting point. For lines that have had recurring root problems, hydrojetting on a regular schedule is one of the most effective ways to extend the life of an aging sewer line without full replacement.

How Inspections Factor Into Maintenance Planning

A sewer camera inspection isn’t just about finding problems — it’s about planning. If the camera shows a pipe in manageable condition with minor root intrusion, you can budget for cleaning rather than replacement. If it reveals significant cracking or offset joints, you have time to plan for pipe lining or replacement on your schedule rather than responding to an emergency backup. That planning window is valuable, especially when financing for larger repairs is part of the equation.

  • Every 3–5 years for homes with newer plastic pipe and no tree coverage
  • Every 1–2 years for homes with clay or cast-iron pipe and mature trees
  • Before closing on a home purchase — always
  • Immediately if you have slow drains throughout the house, gurgling toilets, or sewage odors
  • After any sewer backup, to understand the cause before it recurs
  • When a large tree near the sewer line dies or is removed — roots don’t stop seeking water immediately
