Sewer Scope Inspection – Welland, Niagara Region

See What a Standard Home Inspection Cannot

The main sewer lateral is one of the most important parts of a home that cannot normally be seen during a standard home inspection.

A home may have an updated roof, furnace, electrical system and interior while still having an original clay, cast iron or Orangeburg sewer line underground.

A sewer scope inspection uses a specialized camera to visually inspect the interior of the main sewer line and identify conditions that could otherwise remain hidden until a blockage, sewer backup or major repair occurs.

True Inspection provides sewer scope inspections throughout Welland, Niagara Falls, St. Catharines, Thorold, Pelham, Port Colborne, Fort Erie, Niagara-on-the-Lake, Grimsby and surrounding areas.

Why Have a Sewer Scope Inspection?

Running water at sinks and flushing toilets tells us whether the plumbing is draining at that moment.

It does not tell us what condition the underground sewer lateral is in.

A sewer camera inspection can identify:

Tree-root intrusion
Cracked or fractured piping
Offset or separated joints
Broken or collapsed sections
Standing water or low areas
Heavy buildup or restrictions
Deteriorated clay piping
Corroded cast iron
Orangeburg or bituminized-fibre piping
Damaged ABS or PVC
Previous repairs or improper connections

Some of these conditions can be present even when the drains inside the home appear to be working normally.

Older Sewer Lines in Welland and Niagara Region

Niagara has a large inventory of older homes, and many properties still contain older underground drainage materials.

It is also common to find more than one pipe material in the same sewer lateral where sections have been repaired or replaced over the years.

The age of the home may give us clues, but it does not tell us the actual condition of the sewer.

The camera does.

Vitrified Clay Sewer Pipe

Clay sewer pipe is commonly encountered in older homes throughout Niagara.

Clay itself can remain serviceable for many years, but the line consists of numerous individual sections and joints.

Over time, joints can deteriorate, move or separate. Openings can allow tree roots to enter the sewer.

During an inspection I look for root intrusion, cracking, displaced joints, settlement, standing water and other visible deterioration.

Clay piping does not automatically require replacement simply because it is old.

Its actual condition is more important than the material alone.

Cast Iron Sewer Pipe

Cast iron is also commonly found in older drainage systems.

As cast iron ages, corrosion and scaling can develop along the inside of the pipe.

More advanced deterioration can reduce the internal diameter of the pipe or damage the bottom of the piping.

A sewer camera allows the visible condition to be evaluated rather than making assumptions based on age alone.

What Is Orangeburg Sewer Pipe?

Orangeburg, also known as bituminized-fibre pipe, became commonly used for sewer laterals during and after World War II.

During the war and post-war construction boom, cast iron and other metals were in short supply or subject to rationing. This created demand for alternative building materials, and Orangeburg became an economical substitute for traditional metal sewer piping.

The pipe was manufactured primarily from compressed fibre impregnated with bituminous material. Unlike clay, cast iron or modern plastic sewer pipe, Orangeburg is not rigid.

As it deteriorates, it can:

Soften or distort
Flatten and lose its round shape
Delaminate internally
Become restricted
Allow root intrusion
Lose structural strength
Partially or completely collapse

Orangeburg was commonly installed from approximately the late 1940s through the early 1970s, although the exact period varies by location.

Orangeburg can still be encountered in some older homes in Niagara.

Because the material is now well beyond its expected service life and is prone to progressive internal deterioration and structural failure, when Orangeburg sewer piping is identified, I recommend replacement rather than relying on continued maintenance or monitoring.

The sewer may still be functioning at the time of inspection, but continued operation does not mean the material is in good condition or that failure can be predicted.

For a homebuyer, the presence of Orangeburg should therefore be treated as a significant condition and the cost of replacement should be investigated before purchase.

What About Newer ABS and PVC/SDR-35 Sewer Lines?

Newer homes are much less likely to have the deterioration problems associated with older clay, cast iron or Orangeburg piping. Modern ABS and PVC/SDR-35 sewer piping should provide many years of service when properly installed.

However, new does not necessarily mean defect-free. Problems can occasionally occur during construction, including improper connections, settlement, construction debris or damage to the sewer pipe during backfilling. A rock or other material placed against the pipe during backfilling, for example, can damage the line without producing an obvious problem inside the home immediately.

This is one reason some homeowners choose to have a sewer scope performed on a newly constructed home. The likelihood of finding a significant defect is relatively low, but identifying a construction-related problem while the home is still within its Tarion warranty periods can be important.

Tarion provides one-year warranty protection for defects in work and materials, and its Construction Performance Guidelines also identify certain sanitary drainage conditions under the two-year delivery and distribution system warranty. Actual coverage depends on the nature and cause of the defect.

For a new home, I recommend considering the sewer scope before the end of the first year, so that any construction-related concerns discovered can be documented and reported while the first-year warranty period is still open.

I have encountered this situation during an inspection: damage to a relatively new sewer line that was not apparent from normal operation inside the home but was visible with the sewer camera.

Tree Roots and Sewer Lines

Tree-root intrusion is a common concern with older sewer laterals, particularly clay piping with numerous joints.

A common misconception is that root intrusion is only a concern when there is a large tree on the property directly above or beside the sewer line.

The tree does not necessarily have to be on your property — or even still be there.

Tree root systems can extend well beyond the visible canopy. Depending on the species, soil conditions and surrounding environment, roots may spread a considerable distance from the trunk. Roots from neighbouring properties, boulevard trees and other nearby mature trees can therefore reach a sewer lateral.

It is also possible that a large tree previously existed on or near the property and was removed. The absence of a mature tree today does not tell us what vegetation may have been present several years ago. Existing underground roots can remain after a tree has been removed, and root intrusion that already developed inside a sewer line does not disappear simply because the tree is gone.

Roots generally require an existing opening before entering a sewer pipe. This may be a deteriorated joint, crack, separation or other defect. Once roots reach the moist, nutrient-rich environment inside the sewer, they can grow through the opening and gradually restrict drainage.

A small amount of root intrusion does not necessarily mean the sewer needs immediate replacement. Some lines may simply require periodic cleaning and monitoring.

More significant root intrusion, repeated blockage or evidence of damaged piping may indicate that repair should be considered.

For these reasons, the absence of a large tree in the front yard does not eliminate the possibility of root intrusion in an older sewer lateral.

What Is a Sewer Belly?

A sewer “belly” is an area where part of the sewer has settled and water remains standing in the pipe.

Some standing water does not automatically mean that the sewer needs replacement.

Its significance depends on the depth and length of the affected area, whether waste is accumulating and whether drainage is being restricted.

The camera allows the condition to be observed and documented so an appropriate recommendation can be made.

Sewer Scope Inspections for Homebuyers

A sewer scope is particularly useful during a real-estate inspection.

Most buyers concentrate on visible components such as the roof, foundation, furnace and electrical system.

The sewer is easy to overlook because it is underground.

Unfortunately, repairing a damaged sewer lateral can involve excavation through lawns, landscaping, walkways, driveways or finished basement floors.

Identifying a significant concern before purchasing the property gives you an opportunity to understand the problem and obtain additional information or repair estimates before taking ownership.

An Independent Sewer Condition Assessment

True Inspection does not clean sewer lines, excavate sewer laterals, install sewer liners or sell sewer replacements.

My job is to inspect the visible condition of the line, document what I find and explain the significance of the findings.

I have no financial interest in whether your sewer requires cleaning or repair.

If further work is needed, I will recommend the appropriate next step.

This gives the buyer or homeowner an independent assessment before deciding whether additional sewer work is necessary.

What Happens During a Sewer Scope Inspection?

The sewer camera is introduced through an accessible main cleanout or another suitable access point.

The camera is advanced through the sewer lateral while the interior of the piping is observed.

Where visible, I evaluate the pipe material and condition, joints and connections, root intrusion, cracking, deterioration, obstructions, standing water and evidence of previous repairs.

Significant findings are documented with photographs and included in the inspection report.

Where appropriate, recommendations are provided for monitoring, cleaning, further investigation or repair.

Can the Entire Sewer Always Be Inspected?

No.

The goal is to inspect as much of the sewer lateral as is reasonably accessible, but several conditions can prevent the camera from reaching the municipal sewer.

These can include:

No accessible cleanout
Tight or unusual plumbing configurations
Heavy root intrusion
Significant buildup
Standing water
A blockage
A collapsed or damaged section

I do not force the camera through an obstruction where doing so could damage the equipment or the drainage system.

If the inspection cannot be completed, the limitation and recommended next step will be documented.

Sometimes the line needs to be professionally cleaned before the remaining section can be inspected.

What If There Is No Accessible Cleanout?

Older homes do not always have a suitable accessible sewer cleanout.

The cleanout may also have been concealed behind finished walls, flooring or renovations.

True Inspection does not remove toilets to obtain sewer access.

If toilet removal or plumbing alterations are required, that work must be completed by a plumber.

If suitable access is not available during the inspection, I will explain the limitation and the available options.

No History of Sewer Backups Does Not Necessarily Mean the Line Is Good

Some sewer defects remain functional for years before producing an obvious backup.

Occupancy can also make a difference.

A sewer that appears to function adequately for one or two occupants may begin showing problems when a larger family moves into the home and places a greater load on the drainage system.

That is one reason a sewer scope can be useful even when the seller reports no history of sewer problems.

What If a Problem Is Found?

Finding a defect does not automatically mean the entire sewer lateral needs replacement.

Depending on the condition, recommendations may include:

Monitoring
Periodic sewer cleaning
Root cutting
Further camera investigation
Localized repair
Sewer lining
Replacement of a damaged section

More advanced deterioration may justify replacement of a larger portion of the sewer.

The important first step is determining what is actually there.

Welland Sewer Laterals and the SWAP Program

Welland homeowners should also be aware of the City’s Sewage Water Alleviation Program (SWAP).

Depending on the property and work required, eligible improvements may include items such as backwater valves, sump systems, drainage modifications, cleanout installation and certain sewer-lateral improvements.

Program requirements and available funding can change.

If significant sewer or basement-flooding work is being considered, homeowners should contact the City of Welland before beginning construction to determine current eligibility.

When Should You Consider a Sewer Scope?

A sewer scope is particularly worth considering when:

Purchasing an older home
The sewer material is unknown
Clay, cast iron or Orangeburg may be present
Mature trees are located near the sewer route
There is a history of backups
Drains are slow or occasionally gurgle
Previous sewer repairs are visible
Significant renovations are planned
You simply want to know the condition of the buried sewer before purchasing the property

A home does not need to have obvious drainage symptoms for a sewer scope to provide useful information.

Sewer Scope Inspection Pricing

Added to a Home Inspection

$200 + HST

Having the sewer scope completed during your home inspection allows the findings to be considered along with the rest of the property and avoids the need for a separate appointment.

Standalone Sewer Scope Inspection

Starting at $300 + HST

Pricing may vary where unusual access, property configuration or other conditions require additional inspection time.

Frequently Asked Questions

You Are Not a Plumber. Are You Qualified to Perform a Sewer Scope Inspection?

Yes.

A sewer scope inspection is a visual inspection of the accessible interior of the sewer lateral using specialized camera equipment. It does not involve installing, repairing or altering the plumbing system.

As a home inspector, my role is to identify and document visible conditions such as pipe material, root intrusion, cracked or displaced piping, deterioration, standing water, restrictions and evidence of previous repairs.

I do not perform plumbing repairs, clean sewer lines, remove toilets or alter the drainage system. When a condition requires repair, cleaning, plumbing alterations or further specialized work, I refer the client to a plumber or sewer contractor as appropriate.

I have completed sewer-scope inspection training through InterNACHI and use professional sewer-camera equipment as part of the inspection.

There is an important distinction between inspecting a sewer and repairing one. My service is an independent condition assessment. I do not benefit financially from recommending sewer cleaning, lining, excavation or replacement.

Will the Sewer Camera Damage the Pipe?

Under normal inspection conditions, no.

The camera is designed to travel through drainage piping without cutting or cleaning the line.

If a condition prevents the camera from advancing safely, I stop rather than forcing the equipment farther.

Do You Clean Blocked Sewer Lines?

No.

True Inspection provides sewer camera inspections but does not provide drain-cleaning services.

If cleaning or root cutting is required, I will recommend that the appropriate work be completed.

Do You Remove Toilets to Access the Sewer?

No.

The preferred access point is an existing sewer cleanout.

If a toilet needs to be removed, a plumber will need to perform that work.

Can You Identify the Sewer-Pipe Material?

In many cases, yes.

Clay, cast iron, Orangeburg, ABS and PVC have different visual characteristics that can normally be recognized with the camera.

It is also common to find several different materials in the same sewer lateral where previous repairs have been completed.

Is a Sewer Scope Worthwhile on a Newer Home?

It can be.

Newer homes are less likely to contain deteriorated clay, cast iron or Orangeburg piping, but settlement, damaged piping and installation defects can still occur.

Can a Sewer Scope Guarantee That the Sewer Will Not Fail?

No.

A sewer scope documents visible and accessible conditions at the time of inspection.

It cannot predict exactly when a sewer will fail or guarantee future performance.

Its purpose is to provide considerably more information about a component that would otherwise remain hidden.
