A standard home inspection does not include the sewer line. A camera scope is the only way to know what you're buying. Book before your inspection contingency expires.
A standard home inspection covers the visible, accessible systems of a house — roof, electrical, HVAC, plumbing fixtures, foundation. The sewer lateral — the underground pipe running from the house to the city main — is almost never part of a standard inspection. It is also one of the most expensive systems to repair or replace, with full replacement costs in Denver ranging from $4,000 to $18,000.
Denver and its surrounding cities have significant concentrations of older housing stock. Neighborhoods like Edgewater, Wheat Ridge, Englewood, Sheridan, Arvada's Olde Town area, and Original Northglenn have homes built in the 1940s through 1970s where original clay or cast-iron sewer laterals are still in service. These pipes were designed for a 50–70 year service life. Many are at or past that point.
A sewer camera inspection before closing takes the guesswork out of one of the biggest unknowns in a home purchase. The camera travels the full length of the lateral from the cleanout to the city main, producing live video of the pipe's interior. You see exactly what's there before you own it.
Root intrusion is the most common finding in Denver's established neighborhoods. Cottonwood, elm, and ash trees — common throughout the metro — have aggressive root systems that enter pipe joints and grow inside the line over years. Left unaddressed, roots cause backups and eventually collapse the pipe.
Pipe bellies are another frequent finding: low spots in the lateral where the pipe has settled, allowing waste to pool and solids to accumulate rather than flow freely to the main. Bellies are caused by soil movement — a particular concern in the clay-heavy soils common across the Front Range.
Offset or separated joints occur when sections of clay or cast-iron pipe shift apart due to ground movement, freeze-thaw cycling, or soil erosion around the pipe. A camera shows the gap, the direction of offset, and whether tree roots have entered through the opening.
Corrosion and cracks are visible on aging cast-iron or clay lines. The camera also confirms pipe material — important because Orangeburg pipe (a tar-paper composite used from the 1940s to 1970s) is notoriously fragile and is not a candidate for trenchless lining.
A camera report is a professional document with video footage and a written summary of findings and estimated repair costs. This is a credible basis for seller negotiation. Common outcomes include: seller agrees to repair before closing; seller agrees to a price reduction covering estimated repair cost; a credit is structured at closing; or the buyer decides the condition of the pipe — and the required repair budget — changes their offer calculus entirely.
The key is timing. The sewer scope must happen before your inspection contingency period ends. In most Denver-area contracts that is 10–14 days from acceptance. Schedule as soon as possible after going under contract.
A pre-purchase scope is the same camera inspection used for diagnostic purposes, but the focus is condition assessment and buyer documentation rather than emergency response. The written report is formatted for use by real estate agents, transaction coordinators, and attorneys if needed. The $19 consultation is credited toward the inspection cost.
Prioritize a sewer scope if the home you're buying is any of the following:
