What we run into most

Real-World Drain Trouble We Repair Fast

We've seen every type of clog a home's plumbing can develop. Here are the problems our clients call us about most often.
🍽️

Kitchen Sink Draining Slowly or Not at All

Grease and food particles build up along pipe walls over time, gradually narrowing the channel until water can barely pass. A snake alone often leaves the surrounding buildup intact. We use hydro jetting when needed to fully scour the pipe rather than just punch through the blockage.

🛁

Bathroom Sink or Tub Clogged With Hair

Hair combines with soap scum to form a dense clog just below the drain opening, usually within easy reach of a standard snake. Left alone, it traps more debris and worsens over time. We clear it quickly with the right tool for the job.

🚽

Toilet Won't Flush or Clogs Repeatedly

Excess toilet paper, wipes, or foreign objects are the most common causes of a stubborn toilet clog. A plunger resolves many, but a persistent clog sometimes means the toilet needs to be lifted to clear the trap directly. We handle removal and resetting when necessary.

⚠️

Multiple Drains Backing Up at the Same Time

When several fixtures are affected at once, the actual blockage usually sits in the main line rather than any single drain. Treating it as a simple fixture clog rarely solves the real problem. We diagnose and clear the main line directly.

🔁

Recurring Clog in the Same Drain

A clog that keeps coming back despite repeated snaking usually means the underlying buildup was never fully removed. Continuing to snake the same spot wastes money over time. We use hydro jetting to clear the full pipe interior, not just the immediate blockage.

🔊

Gurgling Sounds From Drains or Toilets

Gurgling usually means trapped air from a partial blockage further down the line, often signaling a developing main line issue. Ignoring it typically leads to a full backup. We locate the blockage and clear it before it worsens.

👃

Sewage Odor Near Floor Drains

A sewage smell near a floor drain usually points to standing wastewater or a blockage trapping gas that should be venting properly. This is both unpleasant and a sign of a real plumbing issue. We identify the source and clear it completely.

💧

Slow Drain That Never Fully Clears

A drain that empties slowly but never stops completely often has partial buildup that DIY methods only push around rather than remove. This gradually worsens until it becomes a full clog. We clear the full blockage so the drain actually returns to normal speed.

Unsure What a Clog Will Actually Cost to Fix

Homeowners often hesitate to call because they are unsure what a clogged drain will cost to resolve. Vague estimates over the phone rarely match the final bill. We give an honest cost range based on the symptoms described before any technician arrives.

Testimonials

Melinda R.

Gave us an honest price over the phone

I explained our kitchen sink had been slow for weeks and Core Ontario Plumbing Services gave me a realistic price range before anyone came out. The technician arrived, confirmed grease buildup, and used hydro jetting to actually clear it instead of just punching through.

Caught a main line issue we didn't expect

We called about one slow bathroom sink but the technician noticed our toilet was also gurgling and correctly diagnosed a main line clog instead of just snaking the one drain. Saved us from a bigger backup a week later.

Ashley N.

Fixed it right, took a bit longer than expected

The clog in our shower drain was more stubborn than the initial estimate suggested and took an extra half hour to fully clear. The price stayed close to what was quoted and the drain has been perfect since.

Corey B.

No callback needed, unlike our last plumber

We had used a different company before that just snaked the drain and it clogged again within a month. Core Ontario Plumbing Services used hydro jetting this time and explained why that would actually solve the recurring problem. No issues since.

Quick response for a bad backup

Multiple drains in our house started backing up at once on a weekend and Core Ontario Plumbing Services got someone out same day. Turned out to be a main line clog from tree roots and they explained the whole situation clearly before starting work.

Toilet clog handled without drama

Our toilet clog needed the fixture removed to clear properly and the technician walked me through why before doing it. Everything was reset and tested before he left, and the price matched the estimate exactly.
