Book a Consultation — Call Now for drain replacement in Ottawa and a fast, honest quote.
Call, text, or book a video pre-diagnosis to show the affected sink, tub, bathtub drain, shower drain, or main drain issue. This helps us understand the problem before the on-site visit.
We complete an on-site inspection and use a sewer camera as needed to inspect the drain pipe, main line, and the home’s plumbing system. This helps us find blockages, leaks, rust, or damaged pipes before recommending next steps.
You receive a clear, itemized quote with repair or replacement options. We explain the process, price, materials, access needs, and whether the drain can be fixed or should be replaced. No deposit is required for most jobs.
We schedule the work, order materials, and prepare access to the pipe, sink basin, tub, shower, underside area, or under-slab location if needed.
We remove the old drain, replace damaged pipes, or install the new drain. For visible sink and tub drains, this may include tightening slip nuts, replacing a rubber gasket, checking threads, using plumber’s putty where appropriate, and securing a watertight fit.
We test the plumbing system, check for leaks, inspect the basin, confirm the sink or tub drains properly, and make sure wastewater flows as it should.
We review the completed work, explain maintenance, share warranty details, and answer any questions about preventing future clogged drains or leaks.
Real feedback from our valued customers based on their genuine experience with Lister Plumbing.
Drain cleaning can solve many clogged drain issues, but it is not always enough. If blockages come back frequently, the pipe may be cracked, rusted, collapsed, or damaged underneath the fixture or inside the wall, floor, or main line.
Signs you may need drain replacement include:
A professional plumber can inspect the issue and determine whether a simple fix, a partial pipe replacement, or a full replacement is the right choice.
Bathroom sink drains and bathtub drains have several parts that must fit tightly to prevent leaks. Depending on the fixture, a replacement may involve a new drain, rubber gasket, slip nuts, stopper, drain body, plumber’s putty, threads, and proper tightening with pliers.
A leaking bathroom sink drain under the basin may not always require full replacement. Sometimes we can fix the issue by replacing the rubber gasket, tightening slip nuts, resealing with putty, or repairing a loose connection. If the drain is rusted, cracked, or poorly installed, replacing it may be the better long-term solution.
For tub or bathtub drain replacement, we inspect the visible drain, stopper, underside access if available, and connected pipes. We make sure the new drain is inserted properly, sealed correctly, and tested before the job is complete.
Larger drain replacement projects may involve pipes behind walls, below floors, under slabs, or running from the house toward the street. These projects require careful inspection, preparation, and professional plumbing experience.
We may recommend a sewer camera inspection if homeowners are dealing with repeated blockages, wastewater backups, or signs of a damaged main line. Camera inspection helps confirm whether the pipe is collapsed, rusted, clogged, or damaged before any replacement work begins.
If only one section is damaged, we may replace just that section. If there are multiple failures, widespread corrosion, or severe pipe trouble, a larger replacement may be more cost-effective.
If you are nearby and need drain replacement, contact Lister Plumbing to confirm availability.
When do I need a full drain replacement instead of drain cleaning?
If sewer camera inspection shows collapsed, rusted, or severely corroded drain pipe, or if blockages return shortly after cleaning, a full drain replacement is the right choice. We inspect first and recommend repair versus replacement based on condition.
Can you replace bathroom sink drains and bathtub drains?
Yes. We replace bathroom sink drains, tub and bathtub drain assemblies, and kitchen sink drain sections. We also reinstall slip nuts, rubber gasket seals, and use plumber’s putty where required for a watertight fit.
How long does drain replacement take in a typical house?
Most visible sink or tub drain replacements take a few hours. More extensive jobs, such as main line or under-slab drain replacement, can take one to several days depending on access and scope.
Do you inspect the main sewer line before replacing drains?
Yes. We recommend sewer camera inspections for suspected wastewater backups or repeated blockages. Camera footage helps pinpoint the damaged pipe and decide whether to replace or repair.
Will you need to tear up my floor or yard for an under-slab or main line replacement?
Sometimes. For under-slab or main line work, we always explore non-invasive options first. If excavation is required, we explain the process, access points, and restoration plan before starting.
Are you licensed and insured to replace drains in Ottawa and Gatineau?
Lister Plumbing operates as a licensed, experienced local plumbing company serving Ottawa and surrounding areas. We carry liability coverage and back work with a one-year workmanship warranty.
What causes recurring clogged drains after cleaning?
Recurring clogs usually mean an underlying issue, such as tree root intrusion in pipes, a broken or collapsed drain pipe, severe grease buildup, or a damaged washer like a failing rubber gasket. A camera inspection finds the cause so we can fix it correctly.
Can you replace only a section of pipe instead of the entire run?
Yes. If the damage is localized, we can cut out and replace the affected section of pipe. For widespread corrosion or multiple failures, full replacement is safer and more cost-effective long term.
Will replacing a drain fix leaks and water damage?
Replacing damaged drain pipes usually stops leaks and prevents further water damage. We inspect surrounding areas, replace compromised pipes, and advise on repairs to underside finishes where necessary.
Do you offer free quotes or promotional discounts?
We provide free quotes on larger jobs and can offer small booking incentives such as $20 off. We also offer video call pre-diagnosis to save you time before an on-site visit.
How do you handle payment and deposits?
We require no upfront deposits in most cases. Payment is simple and typically via e-transfer after job completion. Details appear on your itemized quote.
What materials do you use to replace drain pipes?
We use durable materials suited to the job, such as PVC or ABS for most interior drains and approved materials for main lines. We avoid short-term fixes and focus on long-lasting, quality replacements.
Can you fix a leaking sink drain under the basin without replacing the whole drain?
Often, a leak under the sink can be repaired by tightening threads, replacing slip nuts, replacing a rubber gasket, or applying plumber’s putty. We inspect and recommend the least invasive fix that solves the problem.
What signs should homeowners watch for that indicate a failing drain?
Signs include frequent clogged drains, slow sink or tub drainage, sewage odour, gurgling sounds, visible leaks or damp spots, and water pooling around fixtures. If you notice these, call to book an inspection.
Do you provide follow-up and warranty on drain replacement jobs?
Yes. Lister Plumbing offers a one-year workmanship warranty on our drain replacement work and follows up as needed to ensure your plumbing system performs reliably.
