Some plumbing problems wait until the weekend. Some cannot wait an hour. A pipe bursts behind a wall. A house loses all its water. Sewage pushes back up through a floor drain. These are the second kind. That is the moment you want an emergency plumber in Markham who can come out fast. Water does not sit still. The longer it runs, the more drywall and flooring it wrecks. It ruins whatever sits in the basement, too. You call us with an emergency, and we treat it like one. We keep someone on call 24 hours a day, every day of the year. That includes holidays and the small hours. The first job is to shut the water off. Then we find the source and put your home back to normal.
A drain clogs once. That usually just needs a cleaning. A drain clogs again and again. That points to something bigger down the line. You hear gurgling. The water drains slowly. The floor drain keeps backing up. These signs point to a problem deeper in the system. The cause is often roots or grease in the main sewer. So we do not guess at it. We send a camera down the pipe and look at the blockage. Then we clear it with the right tool. A stubborn kitchen line takes an auger. A packed main drain takes a high-pressure flush. Sometimes the camera shows a cracked or collapsing sewer line. We tell you straight and lay out the options. We do not push you at the most expensive one. We take these calls evenings and weekends too, not just nine to five.
A plumbing problem in a commercial space costs more than the repair bill. A blocked washroom or a leaking supply line shuts a storefront for the day. Every hour it stays closed, businesses walk past the door. We work across these properties: the retail units, the restaurants, the offices, and the property managers who run them. Most of these clients want Markham plumbers who stop the small stuff from turning into big stuff. So we set them up on scheduled maintenance. We catch a slow drain or a tired water heater early. That keeps a closed sign off the door. Bigger problems still happen. A sewer line fails. A backflow problem shows up. We have the equipment and the crew for the larger repair. We get it done without dragging it out for days.
Your water heater quits. A faucet leaks. You do not want to wait a week for the fix. We handle most installs and swaps the same day. We need the part on hand, and the job has to allow it. We install and replace faucets, toilets, sinks, and shower valves. We change out water heaters on both tank and tankless systems. Maybe you are upgrading an old fixture. Maybe one just broke. We bring the new unit, and the old one leaves with us. We make sure the new unit is sealed and running. Then we clean up the bathroom or kitchen. We leave it the way we found it.

Proudly serving Markham with reliable plumbing solutions.
Markham is a mix of old homes and new builds. The plumbing under each one is different. In Unionville, Markham Village, and Thornhill, we mostly see aging water lines and old clay drains. Tree roots get into those drains. In Cornell, Wismer, Greensborough, and Berczy Village, the problems flip. There we see sump pumps and backwater valves that quit early. We see builder-grade parts that do not last.
In the older homes, the trouble hides inside the wall. You do not see it at first. We still find copper and galvanized steel supply lines here. These lines corrode from the inside, and the signs come on slowly. The pressure drops off. The water runs rusty some mornings. Then a stain shows up on the ceiling. That stain is often a pinhole leak behind the drywall. We fix the leaks and cut out the bad sections. Some lines are too far gone to patch, so we repipe those. The drains can be just as old. Many of these lawns have clay sewer laterals underneath. Tree roots work into any crack, and the line backs up. We send a camera down the line first. Then we clear the roots with a flex shaft snake, so the pipe does not collapse.
Newer Markham homes bring their own problems. Many in Cornell, Wismer, and Greensborough went in with basic sump pumps and backwater valves. These have worked for years. Then a spring melt or a bad storm fills the basement. We replace the weak builder-grade pumps and service the backwater valves. We get to them early, not after the flood. In the flood-prone parts of Markham, the City helps with the cost. Markham’s Private Plumbing Protection Rebate Program puts up to $1,750 toward a backwater valve. It puts up to $5,000 toward disconnecting your weeping tiles and adding a sump pump. The rebate is not automatic. The City approves the plan and issues a permit first. Then it inspects the finished work. Thornhill, Unionville, and Markham Village carry the most flood risk.
Hard water is normal in Markham. York Region water carries a heavy mineral load. Scale builds up inside water heaters and fixtures. The tank then works harder than it should, and the bill creeps up. We work on tank and tankless heaters and flush the scale out. Some tanks are past saving, so we size you a new one. We handle the everyday calls too. A kitchen sink backs up. A leak hides behind a bathroom wall. A pipe bursts at 2 a.m. in January. That one cannot wait. We keep an emergency crew on call every day of the year. You reach a local plumber who knows how Markham homes are built.
The price of a repair should be clear before a single tool leaves the truck. You deserve to know where your money is going, not find out once the invoice arrives. That is how we handle pricing across Markham.
Hourly billing rewards slow work and leaves you doing math in your head. Everest Drain & Plumbing charges flat rates instead. A drain cleaning in Markham typically costs $250.00 to $600.00. Leak detection and repair runs $300.00 to $1,200.00, and a tank water heater swap falls between $1,200.00 and $2,000.00 before HST. The number is locked in before we begin.
Markham properties change block to block, from older Thornhill and Unionville homes to newer builds out in Cornell and Wismer. A price quoted over the phone would only be a guess, so we do not give one. A licensed plumber comes to your door, inspects the real problem, and hands you a firm number on the spot. No guesswork, no hidden charges, just a fair upfront price so you can decide what is right for your home.

Pump not working Protecting work area with dropsheets. Remove pump from mainhole and clear the blockage from grainder pump.test and checked working fine. General clean up work area. Disposed any debris. Service description
A main line backup affecting all three units in the building was successfully cleared after safeguarding the work area with protective drop sheets. To access the main drain system, the toilet was temporarily removed, and a heavy-duty drain auger was run forty-five feet through the line to break up and clear the severe blockage. A post-clearing video camera inspection was conducted, confirming that the main line is entirely open, undamaged, and draining freely across all units. The toilet was securely reinstalled, tested for leaks, and a thorough workspace cleanup was completed.

Those are Markham’s named high-risk flooding areas, and many older homes there had downspouts piped straight into the sanitary sewer. That sends roof water into a system never sized for it, helping overload the sewer and back it up into basements, so the City ran a multi-phase program to disconnect them.
For your home, roof water belongs on your property, directed well away from the foundation. If a downspout still drains toward the house, fixing it is one of the cheapest ways to cut your flood risk, and it pairs well with a sump pump.
The water is coming from outside the foundation, not a fixture. Markham’s clay-heavy soil drains slowly and holds moisture, so after rain or snowmelt the saturated ground presses against the walls and pushes water through small cracks, cold joints, and porous concrete.
That points to groundwater management, grading, sealing, weeping tile, and a sump pump, rather than a pipe repair. A water leak detection visit confirms it is groundwater and not a hidden line, and shows exactly where it is entering.
Yes. Markham sits largely on glacial till clay, which drains slowly and stays saturated, pressing against foundation walls and seeping through any weak point. The same clay swells and shrinks with the seasons, and that movement can crack, shift, or sag underground drain lines until flow drops and a backup develops.
It is why two homes on one street behave differently underground. A sewer line video inspection shows whether your line has shifted or cracked, so the repair matches the pipe’s actual condition.
Aware rather than worried. In the older cores of Unionville, Thornhill, and Markham Village, homes built before about 1970 often still run on clay or cast-iron laterals. Clay joints crack and let roots in; cast iron corrodes and scales, narrowing the pipe. Neither tends to fail overnight.
A camera inspection shows the real condition. If the pipe is cracked but intact, trenchless technology can often reline it without digging up a mature lot, and a collapsed section can be replaced before it becomes an emergency.
Usually yes, and many newer homes already have a sump pump because their weeping tile drains to a sump pit. The two devices solve different problems, so one does not replace the other. A sump pump moves groundwater away before it builds pressure.
A backwater valve closes to stop a surcharged city sewer from backing up into your basement. Both are worth having, and a sump pump is far more reliable with a battery backup, since the storms that overwhelm it tend to cut power too. Markham’s rebate can help offset the cost.
Winter snowpack melts faster than Markham’s clay can absorb, and meltwater often hits soil that is still partly frozen, so it has nowhere to go and collects against the foundation, especially on flat lots or ground sloping toward the house. Nearby Rouge River tributaries rising with the melt add to it.
The defences that matter are grading away from the house, clear window wells, downspouts discharging well clear of the foundation, and a sump pump that keeps up, ideally with a battery backup.
Newer does not mean problem-free, and this is common in Cornell, Cathedraltown, Wismer, and Greensborough. The ground keeps settling for years, which can sag or create low spots in drain lines, and the loose backfill against the foundation drains differently from the surrounding clay, so water collects there. Flat grading and leftover construction debris add to it.
A camera inspection shows whether it is a settled line, a partial blockage, or grading. If the home is still under builder warranty, check what that covers first.
