Our Plumbing Services in Ontario
Drain Cleaning and Clog Removal
Nothing ruins a morning faster than a kitchen sink that will not drain or a toilet that keeps backing up. In Ontario family homes we see these issues every week because grease, hair, and hard water buildup take their toll on older pipes.
Common Problems We Fix
- Water standing in the sink after you run the faucet
- Slow draining bathtub even after you clean the strainer
- Toilet that gurgles or rises when you flush another fixture
- Kitchen sink drain that backs up when the dishwasher runs
- Multiple drains in the house slowing down at once
- Bad smells coming from the drain even when it is not in use
- Water pooling around the floor drain in the garage
- Shower that takes forever to empty after you turn it off
We start with a camera inspection to see exactly what is happening inside the line. Then we use the right tool, often hydro jetting, to clear the line completely and flush out the debris so the problem does not return quickly. In winter we pay extra attention to how cold nights affect older lines in Ontario neighborhoods.
Water Heater Repair and Installation
Running out of hot water in the middle of a shower or waking up to rust colored water from the taps is frustrating for any Ontario household. We repair and install every type of water heater including tankless systems that many local families are choosing for better efficiency.
Common Problems We Fix
- No hot water even though the unit is running
- Water heater leaking from the bottom onto the floor
- Loud popping or rumbling sounds when the tank heats
- Rusty or discolored water coming from hot taps
- Pilot light that keeps going out on gas models
- Tankless unit that suddenly stops heating water
- Pressure relief valve dripping steadily
- Unit that is more than fifteen years old and losing efficiency
We diagnose the exact issue, whether it is sediment buildup from our hard water or a failing element, then decide the smartest long term fix. Many older Ontario homes benefit from switching to a tankless water heater that handles the demands of busy families better.
Pipe Repair and Repiping Services
Pipes wear out over decades, especially in Ontario homes built decades ago. Small leaks turn into big water damage if they stay hidden behind walls or under slabs.
Common Problems We Fix
- Low water pressure throughout the house
- Water stains on ceilings or walls that keep coming back
- Pipes that make banging noises when the water turns on
- Rusty water that stains fixtures and laundry
- Visible corrosion on exposed pipes in the garage
- Sudden wet spots in the yard with no obvious source
- Multiple small leaks appearing in different rooms
- Pipes that feel soft or flexible when you touch them
We use modern materials like PEX to repipe when the existing lines are too far gone. The process is designed to keep disruption to your daily life as low as possible while making sure the new lines will last.
Water Line Repair and Replacement
The main water line from the street to your home takes a beating from soil movement and age. When it fails you notice low pressure or wet spots in the front yard fast.
Common Problems We Fix
- Sudden drop in water pressure at all fixtures
- Water bill higher than usual with no indoor leaks
- Wet or soggy area in the front yard near the meter
- Water that tastes or smells different than normal
- Visible rust or leaks at the point where the line enters the house
- Line that was installed decades ago and is now failing
- Repeated small leaks at outdoor spigots
- Line damaged by tree roots pushing against it
We locate the exact problem, then replace only what needs replacing or the whole service line depending on the condition. Modern materials handle our local soil conditions better than the old galvanized pipe ever did.
Toilet, Faucet and Fixture Repair and Installation
Running toilets, dripping faucets, and outdated fixtures waste water and add to your frustration in a busy Ontario household.
Common Problems We Fix
- Toilet that keeps running after you flush
- Faucet that drips constantly even when turned off tight
- Shower head with uneven spray or low pressure
- Sink that rocks or leaks at the base
- Old fixtures that no longer match the rest of the bathroom
- Handle that is hard to turn or feels loose
- Fixture that is cracked or chipped from age
- Outdoor hose bibb that leaks when the hose is attached
We bring fixtures that fit your existing plumbing and style. Installation is clean and tested so everything works the first time you use it.

Quality Services
Plumbing Services
A functional plumbing system is the backbone of any comfortable home or efficient business. From the clean water that flows from your tap to the waste that is safely carried away, every component plays a vital role in your daily life.
Pipe Repair
Water damage from a leaking or burst pipe can be devastating to a property. It can ruin drywall, warp flooring, and encourage the growth of mold. That is why we take every call seriously.
Drain Cleaning
A clogged drain is one of the most common and frustrating issues a homeowner or business owner can face. It starts as a minor annoyance water draining a little slower than usual in the shower or the kitchen sink.
Fixture Install
Updating your plumbing fixtures is one of the most effective ways to refresh the look of your home without committing to a full scale renovation. A modern kitchen faucet or a sleek new bathroom vanity can transform a space instantly.
Garbage Disposal Repair
It works tirelessly to grind up food scraps, making cleanup after meals fast and sanitary. When this appliance fails, however, it becomes immediately obvious. A jammed garbage disposal or a clogged kitchen sink can bring your household routine to a grinding halt.
Water Heaters
Hot water is an essential part of modern living. From a warm shower in the morning to running the dishwasher after dinner, your water heater works silently in the background to provide comfort and sanitation. When this system fails, it is immediately noticeable.
Emergency Plumbing
When a plumbing disaster strikes your home or business, time is the most critical factor. Water damage spreads quickly, and a functional plumbing system is essential for safety and sanitation.
Garbage Disposal Repair and Installation
A jammed or leaking garbage disposal turns a simple kitchen cleanup into a mess. We repair or replace units in homes all over Ontario.
Common Problems We Fix
- Disposal that hums but will not spin
- Unit that leaks from the bottom onto the cabinet floor
- Bad smell coming from the sink even after cleaning
- Disposal that keeps tripping the reset button
- Blades that no longer grind food effectively
- Water that backs up into the sink when the disposal runs
- Unit that is more than ten years old and struggling
- New installation needed after an old one finally failed
We clear jams safely, replace worn parts, or install a new continuous feed unit that matches your sink and daily routine.
Gas Line Services
Gas lines need careful attention because safety comes first. We repair and install lines for stoves, water heaters, and fireplaces in Ontario homes.
Common Problems We Fix
- Gas smell near the meter or appliance
- Stove burner that will not light or stays low
- Pilot light that keeps going out
- Line that was damaged during yard work
- Older flexible line that needs replacement
- New gas line for a new appliance installation
- Corroded pipe connections that leak
- Line that needs rerouting for a kitchen remodel
If you smell gas or suspect a gas leak, go outside immediately and call 911 – this is a serious emergency that needs urgent attention from the gas company.

Slab Leak Detection and Repair
Slab leaks hide under concrete and cause expensive damage if ignored. We find them fast and repair them with minimal disruption in Ontario homes.
Common Problems We Fix
- Unexplained increase in water bill
- Warm spot on the concrete floor
- Soft or spongy area in the slab
- Water stains on baseboards with no visible source
- Low water pressure that started suddenly
- Cracks in tile or flooring that appeared recently

Why Ontario Homeowners Choose Ontario Plumbing Pros
Local focus in Ontario and nearby areas
We live and work right here in Ontario. When a homeowner in Rancho Cucamonga calls about a water heater issue or a family in Upland needs drain cleaning, we know the local water conditions and the common pipe problems in these neighborhoods.
Meticulous diagnostics and fixing the root cause
We never just patch the symptom. In one older home in Chino we traced repeated clogs to a tree root intrusion and cleared the entire line so the problem stayed fixed.
Respect for your home, clean work habits, clear communication
We cover floors, wipe up every drop, and explain exactly what we found and why we chose that repair. Families in Montclair tell us they appreciate knowing what is happening under their floors.
Skilled with modern plumbing systems and tankless water heaters
Many Ontario families are upgrading to tankless systems. We handle the installation and any future service so the unit performs the way it should year after year.
Dependable scheduling and fast emergency response
Whether you book a regular service or call at midnight with a burst pipe, we show up when we say we will. A Fontana homeowner once told us we saved their hardwood floors by arriving within the hour.

Professional Plumbing Repair vs DIY Attempts
Many homeowners try to fix a leaking pipe or clogged drain themselves to save time. In older Ontario homes that approach can lead to bigger problems fast. Water damage spreads quickly behind walls or under slabs, and misdiagnosing a gas line issue creates serious safety risks. Electricity and water do not mix well when you are working on a fixture or water heater. Modern systems have sensitive controls that a homeowner tool kit rarely handles correctly. A small mistake with a drain snake can push debris farther into the line and cause a full backup. Calling a pro early prevents repeated visits, extra damage, and higher long term costs. We have seen too many situations where a simple repair turned into a whole house repipe because the first attempt missed the real cause.
