Drain Cleaning in Quebec

Kitchen lines: grease and food solids. Bathrooms: hair and soap scum. Toilets: wipes (including 'flushable' ones) and sanitary products. Outside: tree roots entering pipe joints and silt. Knowing the likely cause helps the plumber bring the right machine first visit.

Caustic supermarket products sometimes clear light soap/hair partial blocks, but they don't touch grease plugs or roots, they damage older pipes and seals, and they make the drain hazardous for the plumber who eventually opens it. For a fully blocked drain, go mechanical.

Generally you own the pipes within your property boundary, while shared or public sewers are the utility's (or body corporate's) problem. If sewage backs up from a shared line, report it to the utility before paying a private contractor — it may be cleared free.

Keep fats and oils out of the kitchen sink (bin them cooled), fit hair catchers in showers, flush only the 3 Ps, and jet lines with known root intrusion every 12-18 months until the pipe is repaired or relined. Recurring blocks always have a physical cause worth diagnosing.

Relining inserts a resin-saturated liner into the damaged pipe and cures it in place — a new pipe inside the old one, with no excavation. It usually beats dig-and-replace where the pipe runs under driveways, slabs or landscaping, and most liners carry multi-decade warranties.

Yes — shallow or poorly insulated lines can freeze solid, presenting like a blockage. Clearing means thawing (hot-water jetter or steam), not snaking. If it recurs, the fix is insulation or re-grading the line below frost depth.
