Our Service Offerings

We provide professional excavation, repair, and replacement services for sanitary and storm sewer lines, French drains, and water mains throughout the Greater Montreal area, including Ville Saint-Laurent.

Post-Work Camera Inspection

Precise Break Detection: After replacing sewer lines, we offer a camera inspection service. This technology allows us to:

  • Verify the integrity of the new installation

  • Detect potential damage on the public side of the line

  • Provide visual evidence to notify the municipality, if needed

Water Line Replacement: Lead or Steel Pipes

Some older properties are still equipped with lead or steel water lines, which can pose health risks or reduce the performance of the water system. We offer water main replacement using trenchless pulling methods or traditional excavation, installing Type K copper pipes that meet current standards.

  • Lead: Health authorities recommend replacing lead pipes, as they deteriorate over time and can contaminate drinking water.

  • Steel: With a lifespan of around 40 years, steel pipes become brittle, prone to rust, and susceptible to leaks.

Why Do Your Sewer Lines Get Clogged?

Sewer blockages often occur due to old concrete, clay, or cement pipes that are no longer watertight. Over time, these materials can deteriorate, collapse, or allow tree roots to infiltrate—leading to major obstructions and, in some cases, sewer backups inside the home.

  • Eliminates the risk of root infiltration

  • Prevents future blockages and backups

  • Ensures reliable, long-lasting drainage for your property
