Both. Pipe relining works on sanitary sewer laterals and on interior or exterior water supply lines, as long as the existing pipe can hold a liner and cure it in place. St. John's has plenty of older homes in neighbourhoods like Rabbittown and the Battery where the original clay or cast iron lines are still in the ground, and those are usually the best relining candidates.

For sewer laterals, we follow ASTM F1216, the standard that governs cured-in-place pipe rehabilitation across North America and typically extends service life by decades. Water lines need a liner rated for potable use and pressure, so not every damaged line qualifies. A camera inspection tells us within the hour whether your specific pipe is a fit, or whether a section needs to be replaced instead.

Root intrusion, hairline cracks, and minor offset joints are usually good candidates for relining. A collapsed pipe, a severe belly where the line has sunk, or a section crushed under a driveway usually isn't, since the liner needs a mostly intact host pipe to bond to.

St. John's sits on shallow bedrock in many areas, so ground movement and frost heave can shift older lines more than homeowners expect, especially on properties near Bannerman Park or in the older downtown core. A sewer camera inspection is the only reliable way to tell the difference, and it usually takes less than an hour.

As a rule of thumb, if less than 25 to 30 percent of the pipe run shows structural damage, relining is often the more cost-effective fix. Beyond that, a full section replacement usually makes more sense.

Yes. The City of St. John's requires plumbing permits and inspections for repair and renovation work on existing plumbing systems, and trenchless sewer rehabilitation falls under that requirement even though no trench gets dug. Our licensed plumbers handle the permit application and schedule the required inspection so you don't have to track down City Hall paperwork yourself.

Skipping the permit step can create real problems later. If a home inspector or the City flags unpermitted plumbing work during a future sale, you could be asked to expose the line and redo it. We've seen that happen to a few sellers in Mount Pearl trying to close a deal quickly, and it always costs more time than pulling the permit up front.

Yes, mostly because of the freeze-thaw cycle rather than deep cold alone. St. John's gets roughly 1,268 millimetres of precipitation a year, much of it as rain, sleet, and wet snow that soaks the ground and then refreezes repeatedly through the winter. That constant expansion and contraction stresses aging clay and cast iron pipes at their joints, which is exactly where root intrusion and small cracks tend to start.

Homes built before the 1980s in areas like the Southside Hills or older parts of downtown are the ones we see most often for this kind of seasonal damage. If your line backs up every year around the same time, especially after a wet fall followed by a hard freeze, that pattern alone is worth a camera inspection before it turns into a full blockage.

The liner itself typically carries a manufacturer warranty backed by decades of independent testing, since ASTM F1216 requires cured-in-place liners to meet minimum flexural strength and chemical resistance benchmarks before approval. On top of that, our workmanship is covered under the Neighbourly Done Right Promise®, so if something about the installation itself isn't right, we come back and fix it.

What the warranty won't cover is new damage from an unrelated cause, like a fresh root intrusion three metres downstream of the relined section, or a separate line that was never part of the original job. During your camera inspection, we'll walk you through exactly which sections we're relining and why, so there's no confusion later about what's under warranty and what isn't.
