DRAIN SERVICE
Rock Basements can inspect your drain with camera and suggest further action.
Our team can replace interior drain under basement slab as well as outside connection to city line.
DRAIN SERVICE

Entire house drain replacement costs $2000 - 12000 with excavation, drain replacement, backfill and finishing concrete inside the house.
Call for camera inspection at $500 for detailed examination of sewer line.

Types of Drain Services
Interior
Sewer lines that are blocked or damaged inside the house under slab are replaced with performance of trench excavation and finishing concrete slab after the work is completed.
Exterior
If the problem goes outside of the house and sewer line is damaged past the house boundaries, deeper trench needs to be excavated in order to replace it. Our team backfills it later and protects lawn in the process.
Requirements
by Rock Basements
1. Permit: Replacement of drains in Toronto requires permit. After new sewer lines are installed, inspector checks the slope and connections.
2. Drawings: If drains are being replaced as part of larger renovation process, we need a set of drawings to know where stacks and lines need to come out.
3. Basic Details: Most of the time sewer lines are being replaced on same location, but sometimes clients may want to implement changes.
4. Access: Once we have arrangement for work, we need to confirm access to property and parking.

Steps in Drain Replacement
Inspection
Before doing any work it is logical to fully inspect the problem of drain pipes.
We always recommend camera inspection. This will allow us to look inside the drain and go further towards city line.
There could be several issues with the line and solving one problem may not be enough.
Demolition
Prior to excavation Rock Basements needs to demolish literally everything that is on the way.
Inside the house, floor may need to be taken apart with demolition of concrete slab where digging will take place.
Outside work may require some parts of deck/porch to be taken out
Excavation
Next we need to dig a trench, expose existing drain pipe with space to work around it.
Interior work is always done by hand, unless entire basement is fully excavated and we need to place new pipes.
If there is space outside, we may use small excavator for this stage.
Replacement
New drain pipe is placed in trench and connected from both sides.
Inspection is called for interior work with what we call "Ball Test" to make sure there is enough slope for natural downward drainage.
Old pipe is taken out and disposed with broken concrete and leftover soil.
Backfill
Now that new pipe is in and fully inspected we can start put dirt back in trench.
Gravel is placed all around drain pipe to make sure it does not move later on and slope is not disturbed when backfilling.
Typically there is soil left to take out due to new gravel and layer of concrete.
Finish
When working inside we always finish with layer of concrete to match existing slab.
Clean up is done during outside and inside drain replacement. Tarps are washed and floor is swept with all bits and pieces going to garbage.
We want to leave the job site as clean as it was before we showed up.
How Drains Get Blocked/Damaged
Most Popular Reasons
1. Old Pipes: With age older pipes wear out and can collapse. even small cracks can lead to full blockage within few month.
2. Toilet Blockage: Flushing larger items into toilet can get it blocked. Luckily it does not always mean entire pipe needs replacement.
3. Kitchen Blockage: Similar to previous point, flushing parts of food and paper towels can lead to blockage of sewer pipes. Can be solved with Snaking.
4. Roots: Nearby tree and large bushes roots can get inside older clay or iron pipes. This will cause collapse of pipe with full blockage.
5. Soil Pressure: Sewer pipe outside of the house sits 6-8 feet below ground. Clay pipes can collapse under pressure after being there for decades.

When To Replace Sewer Line - Drain
Finishing Basement
Rock Basements strongly recommends replacing old drain pipe before refinishing or renovating basement.
This ensures extra protection for newly renovation basement and you wont have to completely take apart flooring with baseboards to replace clogged drain.
Underpinning
Another time when sewer lines are replaced is lowering the basement floor with excavating deeper than existing drain.
Honestly, there is no option to leave existing drain lines as they were. We need to replace drain simply because excavation is going below and we just need to lay new pipes.
Home Addition
Often enough we install new sewer liens during home addition. It may be rear addition or second floor top up with gut renovation.
During rear addition, new stack or washroom may need sewer extension, while second floor addition simply makes sense to add drain replacement into scope while its gutted.
Full Blockage
While previous examples were simply options that clients can choose to do as part of the project, blockage means at least snaking or fully replacing drain pipe.
With age, pipes tend to accumulate small debris and it just adds up to become complete blockage of sewer pipe.
Damaged Pipe
As previously stated, we recommend full investigation and camera inspection of entre length of drain pipe to see if it is damaged or cracked in some places.
If collapsed, damaged or cracked you need to replace it immediately to avoid blockage and backup to toilet and flood in your home.
Upgrade
Each part of the house should be inspected every 5 or so years. Clay drain pipes serve up to 30-50 years and it may be time to upgrade it even before it shows signs of damage.
Proactive measures are less expensive and can prevent additional costs of mandatory demolition in route of pipe.

Frequently Asked Questions
Interior drain installation or replacement requires city permit. Inspectors want to check if it is properly installed with correct slope towards city main line.
Exterior drain repair and replacement does not require permit and even inspection when renovating the house. However, during new construction, both interior and exterior lines and connections are inspected.
Always take pictures of your work before backfilling.
The lasting of drain pipe depends on proper installation technique and material the pipe is made of.
Although cast iron pipes are not recommended for installation anymore, their lifespan is higher than currently popular PVC pipes. Cast Iron Drain pipe lifespan is on average 80 years.
PVC are belived to have slightly shorter lifespan with approximately 60 years, but are recommended by most building associations and local building codes due to safety of use.
Another type of drain pipes are Clay. They are no longer being installed but were serving on average 50-70 years.
Lifespan can be significantly shortened by damage from roots and cave ins.
No, drain and plumbing contractors are not allowed to touch or replace drain that is on city property. We can replace or install new drains inside the house (under the slab) and underground up to city property.
City drain is replaced by their own crew. We can help contact and submit required forms for sewer replacement on sity property. If you are caught digging a trench and working on drains at city property, investigation will begin with further fines.
When building a new homes, old sewer pipes are demolished with existing house in the first stage of construction.
As per building code, new lines are required from city. We need to submit a form and schedule installation that typically takes two month. Further we proceed with excavating a trench, connecting drain pipe to where city has installed their line and dragging it inside the house, where underground lines are installed for bathrooms, laundry and stacks.
All this work has to be performed in sequence prior to installing heated floor and finishing basement slab.
In Toronto there are 5 main reasons for sewer drain blockage that Rock Basements comes across while performing replacement.
5 Drain Blockage Reasons:
- Food Remains – After cooking, cutting vegetables or washing dishes, food remains are often flushed down the drain from kitchen sink. Grease and cooking oil is added to the mix that potentially can block sewer system.
- Tree Roots – Neighboring trees spread the roots deep enough to penetrate old drain pipe. Sewer system has lots of water that goes through and roots expend inside pipe to completely block it.
- Pipe Collapse – old pipes can crack and collapse under weight of soil. Sand and dirt is pushed inside sewer drain and it gets fully blocked.
- Foreign Object – unfortunately many objects are being flushed down the drain and get stuck inside on connections. This typically happens with kids and rental properties that are not being thoughtful.
- Outdoor Debris – walkout floor drain is connected to sewer system that travels to city. Leaves and dirt always get inside and can potentially create a blockage that will lead to snaking or pipe replacement.
Rock Basements responds to all emergency calls regarding drain blockage and potential flood of the house. If we serve your area, one of our crews can attend job site within hours to inspect and start fixing the issue. Drain blockage is a huge problem that can lead to flooding the house, electrical and fishing damages that are extremely expensive to fix. Call us as soon as you find out about such problems.
One of the most common questions we hear from clients when trying to save money on sewer fix is if only parts of the drain can be replaced instead of changing entire line.
If drain pipes are relatively new, locating and fixing the issue can be with partial drain repair.
If drain pipes are old, than removing blockage and fixing parts of sewer system would be a temporary fix. Old pipes are better to replace completely while excavation starts.
We strongly recommend calling professionals to replace or install new drain. Although it may look as easy weekend project, there are many technical details that installers need to know. Sloping, connection and venting are just the beginning of proper workmanship. Improperly installed drain pipes will lead to further problems.
Instead of doing it several times, call Rock Basements right away and receive warranty for our work.
Yes, drain replacement is complicated part of home construction that is strongly regulated and requires city inspection.
Upon completion of excavation, gravel pad and pipe installation with ongoing connections, city inspector is called to approve work with “ball test”. They typically ask to put billiard ball that will roll on itself to end point due to created slope.
Clients don’t have to do anything as Rock Basements takes care of scheduling and attending inspection for drain installation.
There are many methods to prevent basement from floods and some of the do connect to main drain system. We are not talking about waterproofing with delta membrane and installing weeping tile around perimeter of exterior walls.
Backwater valve is a system that connects to drain and prevents everything from the city to back up and overflow toilets or floor drains.
This valve detects flow backwards and stops it completely. City of Toronto has rebates for such installation and requires it in multi units.
