When a townhouse drain backs up, the first useful question is whether the water is yours. If nobody in your home was running a tap when the tub filled, the blockage is probably in a line you share. For drain cleaning in Sunrise, phone One Call Home Pros and describe what happened and where. One Call finds a vetted local drain professional, licensed and insured for the work, who knows common-wall construction, and keeps an eye on the job until it is done.


Why Sunrise townhouses need drain work done with the neighbours in mind
Sunrise is large and suburban, and most of it went up between the 1970s and the 1990s. It holds a big share of the county’s townhouse stock, and that shapes drain work more than anything else in the city.
In a townhouse row, units are built against one another with common walls. To save space and pipe, builders often ran a single vertical drain stack inside a shared wall, with the kitchens or bathrooms on both sides connecting into it. Lower down, units may share a branch or a main line that runs behind the row before it reaches the street.
That has real consequences. A blockage in a shared stack affects both homes. A repair to a pipe inside a common wall means opening a wall that belongs, at least in part, to someone else. And the drains themselves, now decades old, carry buildup from more than one household. A pro who has worked in common-wall buildings knows how to find the problem without opening more than necessary.
Drain issues common in Sunrise homes
Slow on one side of the wall
A sink or tub that drains slowly while your neighbour’s is fine. Usually your own branch before it meets the stack.
Slow on both sides
Both homes backing up. The shared stack or shared line is the likely cause.
Backups into the lowest drain
A downstairs shower or tub filling with water that came from somewhere else. A blockage further down the line.
Roots in the line behind the row
Landscaping between rows and along the back of units reaching older pipe.
Camera inspection
A look inside the stack or line to find the blockage without opening walls.
Jetting or the cable
The pro picks the method that suits the pipe and the shared layout.
Working out whose drain it is
In a common-wall home, the answer to “whose drain is it” decides who arranges and often who pays for the work. A simple test helps.
- Run water at the slow fixture on its own. If it drains slowly and nothing happens elsewhere, the problem is in that fixture’s branch.
- Ask your neighbour to run water in the room that backs onto yours. If water rises in your fixture when they do, you share a line and the blockage is past the junction.
- Check whether downstairs fixtures fill when upstairs ones drain. If so, the stack or the line below it is restricted.
- Ask whether anyone else in the row has had trouble recently.
If the blockage is in your own branch, you can arrange the work. If it is in a shared stack or line, check your association’s documents. In many townhouse communities, shared lines are the association’s responsibility; in others, the owners who share them split it.
What a shared stack means for the work
A stack in a common wall is reached in one of a few ways: through a cleanout on the stack itself, through the roof vent at the top, or through a fixture connected to it. Most of the time a pro can clear a shared stack without opening the wall at all.
Problems come when the pipe inside the wall needs repair. Then the choices are harder:
- Opening from your side. The pro cuts drywall on your side of the common wall to reach the pipe.
- Opening from the neighbour’s side. Sometimes the pipe is easier to reach from next door, which means your neighbour’s agreement and access.
- Working from above or below. In some layouts the pipe can be reached from a ceiling or floor rather than the wall.
Any of these needs a conversation with your neighbour and usually your association. A pro will want that settled before cutting anything.

Decades of buildup
The drains in a Sunrise townhouse from the 1970s, 1980s or 1990s have had a long time to collect. Depending on the community and its age, the pipe may be cast iron, plastic, or a combination where sections have been replaced.
In metal pipe, the inside rusts and scales, narrowing the bore and roughening the surface. In plastic pipe, grease and soap still form a coating, and joints can shift. In both, a shared stack carries the waste of two households, so it fills with buildup faster than a single home’s drain would.
Kitchen stacks are often the worst. Grease from two kitchens cools and hardens on the walls of the same vertical pipe, and over the years it builds into a thick lining. A kitchen sink that drains slowly on both sides of a wall is often a sign of exactly that.
Upstairs and downstairs
Most Sunrise townhouses are two storeys, which adds a second dimension to drain trouble. Upstairs bathrooms drain down through the stack, past the ground floor, to the line below the slab.
If an upstairs drain is slow but nothing downstairs is affected, the problem is likely in the upstairs branch. If downstairs drains back up when upstairs fixtures are used, the problem is below the point where they meet, often in the stack’s lower section or the line under the slab. If a downstairs toilet bubbles when an upstairs shower runs, air is being pushed through a partial blockage further down.
Telling One Call which floor shows the problem, and whether the other floor is involved, saves time on the day.
Detached houses in Sunrise
Not every home in the city shares a wall. The detached suburban houses built across the same decades have simpler drain systems: every line, from the fixtures down to the connection at the street, belongs to the house. Drain cleaning in Sunrise for a detached home therefore skips the neighbour conversation, but the age of the pipe is the same.
These houses are on slabs, with branches under the floor feeding a main that runs out through the yard. The main is where most serious trouble starts, because it carries everything and it is the line closest to the trees. If several drains slow at once, or the lowest shower takes on water, the main is the likely suspect, and the outdoor cleanout is where the pro will begin.
A smell that will not leave
A sewer smell in a townhouse bathroom has several possible sources. A trap that has dried out in a little-used fixture is the simplest, and running water for a short while fixes it. A vent that has become blocked, so gases cannot escape through the roof, is another. In a shared stack, a partial blockage can push air, and odour, back up through the fixtures on both sides of the wall.
If the smell stays after you have run every fixture, or it comes with gurgling, mention both when you call. The pro may check the vent as well as the line.
When water rises through the floor
The worst case in a townhouse is a backup into the lowest fixture: a ground-floor shower, tub or toilet filling with dirty water. In a shared system, that water may come from your neighbour’s home as much as yours.
If this happens:
- Stop using water in your home and ask your neighbour to stop too.
- Keep children and pets away from the water.
- Move rugs and furniture away from the affected area.
- Tell your association if the line is shared.
- Do not pour chemicals into the drain. They will not reach the blockage and they make the line hazardous to open.
Then call One Call. Tell us the water is rising and that the line may be shared.

How One Call arranges drain cleaning in Sunrise
Drain and sewer work requires a licence, and that licence is held by the pro, not One Call. What One Call brings is the arranging: listening to what is happening, choosing the right professional and keeping track of the job.
For a common-wall home, our questions go a little further than usual. Is the problem on one side of the wall or both? Upstairs, downstairs or both? Has your neighbour noticed anything? Does the association handle shared lines? From those answers, we pick a vetted local pro who works in townhouse rows and send them with the right expectations.
At the visit, the pro finds and clears the blockage and tells you where it was and what caused it. That location matters, because it shows whose line it was. One Call handles the money side: you pay One Call, and One Call pays the pro. Ask before the work starts what the job covers. If the line stops again, let One Call know.
The visit, step by step
In a townhouse, the pro usually works in this order:
- They hear what you have noticed and check whether the problem is on one side of the wall or both.
- They look for the best way into the line, which may be a stack cleanout, a fixture, an outdoor cleanout behind the row or the roof vent.
- They tell you what they intend to do and what it covers before starting.
- They clear the blockage and run water on both floors to check flow.
- They explain where the blockage was, which matters for deciding whose line it sat in.
If your neighbour is affected, it helps if they are home or can be reached during the visit, so the pro can run their fixtures as well. Good drain cleaning in Sunrise townhouses often depends on checking both sides.
Seeing inside the stack
A camera inspection is especially useful in common-wall buildings, because it shows the pipe without opening the wall.
The pro feeds a small camera on a cable into the stack or line. On a screen, they see what is blocking it, how far along it is, and what condition the pipe is in. If the pipe needs repair, the camera can show exactly where, so only the smallest possible section of wall or floor needs to be opened. If the blockage is in a shared section, the camera record gives you and your association a clear picture of what was found.
The pros One Call works with offer camera inspection and hydro jetting. The pro decides when a camera look is needed, often after a line has blocked more than once, or before recommending any repair inside a wall.
Cable machine or hydro jetting
A cable machine, or snake, sends a rotating head through the pipe to break up the blockage. It is the usual first step, and on a single branch line it is often all that is needed.
Hydro jetting uses high-pressure water to scour the inside of the pipe. On a shared kitchen stack lined with grease from two households, it can clear the whole wall of the pipe rather than just making a hole through the buildup. On older metal pipe, the pro will usually check the condition first with a camera, because a weakened pipe inside a common wall is the last place anyone wants a leak.
The pro will explain the choice. If you are sharing the cost with a neighbour or the association, it helps if everyone understands why one method was picked.

Repairs inside a common wall
If the camera shows a cracked or broken section in a shared wall, drain cleaning in Sunrise turns into a repair job. Before it begins, a few things need to be agreed:
- Who is responsible for the pipe, under your association’s documents.
- Which side of the wall will be opened, and who restores the drywall and paint.
- Whether a permit is needed. Repairing or replacing drain pipe usually requires one, and the licensed pro applies for it.
- Whether the association needs to approve the work.
Financing is available for larger repairs. Ask about it when you call.
Talking to your neighbour first
Because so much of a townhouse’s drainage is shared, a short conversation next door can save a wasted visit. Ask whether their drains are slow, whether they have heard gurgling, and whether they have had a pro out recently. If they have, find out what was found and where. A stack that was cleared from their side last month and is blocked again now tells the next pro a lot.
If both homes are affected, consider booking one visit for both. The pro can work the shared line once, run fixtures on each side, and give you both the same account of what was in the pipe.

Roots behind the row
Townhouse communities from these decades planted trees and hedges between rows and along the backs of units. Those plants are now mature, and where a drain line runs behind the row, roots find their way into any gap at a joint. A shared line with roots in it slows for every unit upstream of the root mass.
Roots show up as drains that clear and then slow again within weeks, often with gurgling. The camera finds them, and cutting them out restores flow. Because they regrow, a shared line with roots usually needs a longer-term decision from the association: regular cleaning, a repair at the joint, or replacement.
Keeping a shared drain clear
In a shared system, everyone’s habits add up. A few that help:
- Keep grease out of the kitchen sink. Pour cooled fat into a container and bin it.
- Use strainers in sinks and hair catchers in showers.
- Flush only toilet paper.
- Run hot water after washing up.
- If you notice slow drains or gurgling, mention it to your neighbour. They may have noticed it too.
Before you book
A short checklist makes the first call faster:
- Which fixtures are affected, and on which floor.
- Whether your neighbour has the same problem.
- Whether water has risen anywhere, and where.
- Whether the association has been told.
- Where the cleanout is, if you know.
Leaks and drips are a separate job
A dripping tap, a running toilet, a leaking trap or a cracked fixture needs plumbing work, not drain clearing. Let One Call know what you see and we point it to the right trade.

Questions from Sunrise
My downstairs shower fills with water when my neighbour showers. Why?
You share a line, and it is blocked below the point where your drains join. Ask your neighbour to stop running water, tell your association, and call One Call.
Will the pro have to open my wall to clear a shared stack?
Usually not. Most stacks can be cleared through a cleanout, a roof vent or a fixture. Walls are opened only when the pipe itself needs repair.
Who pays to clear a shared line?
It depends on your association’s documents. Often the association covers shared lines; sometimes the owners who share them split the cost. Check before the work starts.
Can a camera show where the blockage is without cutting anything?
Yes. It shows what is in the pipe and how far along it sits, so any repair opens as little wall as possible.
Get the line cleared
