A job I will never forget

Before we arrived
A family’s kitchen sink had caved in after long-term water damage.

What I found
The sink was literally hanging into the cabinet. The countertop support had rotted out, so the basin had nothing solid to sit on.

What I did
I built a new wooden countertop support frame the same day to carry the weight. The next day, after the support cured and settled, I installed and sealed the sink, set the clips, rebuilt the drain, and tested everything.

Outcome
They got their kitchen back with a solid, sealed sink that would not leak or shift. No more water damage risk, and no surprise failures under the counter.

Toronto specifics we see often

• Older homes in Mississauga
  We often find water-softened particleboard vanities and improvised supports. If the rim is not sealed or the clips are loose, a sink can slowly pull away and start leaking. Reinforcement and a proper seal stop the cycle.

• Condos and multi-unit buildings
  Access and shutoffs can be tricky. We coordinate with building management, book elevator times when needed, protect corridors, and work clean so neighbours stay happy.

How we install your sink, start to finish

1. Quick call to understand your sink type and goal

2. On-site assessment and flat-rate quote before any work

3. Protect floors and vanity, shut off water, verify shutoff valves

4. Remove old sink and faucet, cap lines, inspect cabinet and counter

5. Reinforce or rebuild support if needed so the basin is rock solid

6. Bench-mount faucet and drain where possible for a cleaner install

7. Set the sink, level it, apply the right sealant, attach clips or brackets

8. Connect braided supply lines and quarter-turn angle stops if required

9. Rebuild the drain and P-trap with correct slope and alignment

10. Pressure and leak test, fill-and-drain test, and pop-up function test

11. Final seal, cleanup, and haul-away of the old fixture

12. Walkthrough of care tips and what to watch for

Checks we never skip before we leave

• No drips at supply lines, shutoffs, faucet base, or drain joints

• Fast, quiet drainage with a full-sink dump test

• Pop-up opens and closes smoothly and seals fully

• Silicone bead is continuous and clean

• Sink does not flex, rack, or shift when pressed

Parts and methods we trust

• Supply lines: braided stainless with proper length and ferrules

• Traps and tailpieces: solid 1¼-inch or 1½-inch components with tight unions

• Sealants: 100 percent silicone where called for, plumber’s putty where appropriate

• Valves: quarter-turn shutoffs so future maintenance is simple

What we avoid: accordion traps that collect debris, mixed-metal stacks that corrode, off-size fittings that never seal quite right.

Pricing and what changes it

We price flat rate after an on-site look, so there are no surprises. Like-for-like swaps are the fastest and most affordable. Costs increase when we need to install an undermount that requires curing time, add blocking for a wall-mount, rebuild a drain and P-trap, or reinforce damaged cabinetry. If extra work is needed, we explain why, show you the issue, and give you the new price before we continue.

Common mistakes we fix in GTA homes

1. No or wrong sealant around the rim, leading to rot and sink movement

2. Reusing brittle traps and old supply lines that start dripping days later

3. No shutoff valves at the sink, turning small repairs into big jobs

4. Drains set at the wrong height, causing standing water and slow flow

5. Wet countertops never dried before resealing, so the bond fails

Frequently Asked Questions

What are the signs of a clogged residential sewer drain?

Slow drains in multiple fixtures, gurgling, sewage odours, water pooling outside, or recurring toilet backups are red flags. Damp spots along the basement floor count too. Call for clogged drain service before it becomes a full backup.

How do you unclog drains in a sewer system?

We diagnose first, then choose the right method.

• Video camera inspection to locate blockages or damage without digging

• Hydro jetting to clear grease, sludge, and roots

• Mechanical augering and snaking for minor clogs

• Trenchless spot repair or pipe lining when the pipe itself is damaged

Why is regular drain cleaning important for my home?

It keeps wastewater moving, prevents backups and odours, and catches small issues early. Clean drains also protect new fixtures, including anything our bathroom sink installers put in for you.

What types of commercial drains can Drain Rooter Plumbing repair?

All of them. Washrooms, commercial kitchens, prep areas, manufacturing floors, hospitals, warehouses, parking garages, and multi-unit buildings. From floor drains to grease lines, we keep your business compliant and running.

How can regular commercial drain cleaning help my business?

You avoid downtime, pass inspections, reduce odours and bacteria risks, and extend pipe life. Scheduled hydro jetting and targeted snaking keep lines clear so your team can focus on customers, not clogs.

Do you offer financing for plumbing repairs?

We provide written estimates and accept major payment methods. For larger projects, ask about current payment options and we will walk you through what is available.

Why choose Drain Rooter Plumbing over other companies?

Licensed and insured plumbers, flat-rate pricing before any work, on-time uniformed techs, clear communication, and workmanship we stand behind.

How do you handle emergency plumbing?

Call us and we will prioritize your job. Same-day and after-hours help is often available. We stabilize the issue fast and complete a lasting repair.

What is your workmanship guarantee?

We back our labour with a written guarantee and honour manufacturer warranties on parts. Your quote lists what is covered.

Do you install customer-supplied bathroom sinks and faucets?

Yes. We install pedestal, undermount, vessel, drop-in, wall-mount, and vanity sinks. We confirm compatibility, add shutoff valves if needed, seal and level the basin, connect the drain and P-trap, and test for leaks.

How long does a bathroom sink installation take?

Most installs take 1 to 2 hours. Add time if we are modifying the vanity, moving plumbing, or replacing the faucet and drain assembly.

We also install and service kitchen and laundry sinks

Although you found us searching for bathroom sink installers, our team also handles kitchen sinks, laundry tubs, dishwasher drain hookups, and garburator/garbage disposal installs or removals.
