FAQs
What are the most common warning signs of a mystery blockage in my main sewer line?
Slow-draining fixtures throughout the house, recurring backups in toilets or floor drains, gurgling sounds from sinks or tubs, foul odours near drains, and water pooling around basement floor drains are all red flags. Because every fixture ultimately ties into the main line, simultaneous problems in multiple locations almost always point to a main line obstruction rather than an isolated clog.
What typically causes a main line blockage in Thorn Hill?
In our area, the leading causes are tree-root intrusion (especially from mature maples and willows), accumulation of grease and food waste from kitchen sinks, collapsed or bellied clay pipes in older homes, foreign objects flushed down toilets, and heavy scale build-up in cast-iron lines. Seasonal freeze–thaw cycles in Thorn Hill’s clay soil can also shift pipes and create weak spots where debris collects.
How do you pinpoint the exact location of the blockage?
Our plumbers start with a high-pressure auger or hydro-jet to see if the obstruction clears. If it doesn’t, we feed a colour HD sewer camera through the clean-out. The camera transmits a live video feed and depth reading so we can see the blockage, measure its distance from the house, and map its position relative to surface landmarks. This non-invasive method lets us recommend the most cost-effective repair—whether spot repair, pipe-bursting, or a full replacement.
Is a camera inspection really necessary if I just want the line cleared?
A simple power-snaking can give temporary relief, but it won’t reveal why the clog formed or whether the pipe is damaged. A camera inspection adds only about 30–45 minutes to the service call and saves money in the long run by preventing repeat blockages and unexpected sewer backups. It also produces a digital record for insurance or resale purposes.
What are my repair options if the main line is damaged?
Depending on the pipe’s condition and location, we offer trenchless pipe lining (cured-in-place epoxy), pipe-bursting to insert a new HDPE line, or traditional open-cut replacement. Trenchless methods require only one or two small access pits, preserve landscaping, and can usually be completed in a single day. During your consultation we’ll explain the pros, cons, life expectancy, and cost of each solution.
