The main sewer line is one of the most expensive components in a home to replace. Costs can range in excess of $10,000.00. Pro Spex has inspected well over 10,000 homes since 2003, in that time less than 0.1% have requested a sewer inspection, however several homes have gone on to experience sewer backups after purchase. Backups that have result in inconvenience and costs 10 times the cost of a sewer inspection.

Reasons to Inspect the Sewer Line

Standard home inspections do not cover the structural integrity or condition of sewer or septic lines. A sewer scope provides an innovative approach to make an educated buying decision, plan for upcoming maintenance, budget for necessary repairs, or gain valuable purchase price negotiation. The following videos is a discovery we made on a $1,8M custom home. Imagine if we had not discovered this and the buyer had moved in.


This customer was fortunate we discovered this in the basement, what was happening underground was anyone’s guess.

A home inspection, cannot detect what we cannot see. Nobody knows what may be stuck in that line, whether or not it is damaged or even if settlement has changed the slope making it difficult to drain.

For your protection, get a sewer scope inspection.
