Is pipe relining a good option for old homes?

Pipe relining is an excellent option for many older Ottawa homes, and it's often the most cost-effective way to restore aging sewer and drain lines without the disruption of traditional excavation. That said, whether it's the right choice depends on the condition and material of your existing pipes.

What Pipe Relining Actually Does

The process involves inserting a flexible, resin-coated liner into your existing pipe, then inflating and curing it to create a smooth, jointless "pipe within a pipe." The result is essentially a brand-new interior surface that seals cracks, root intrusions, and joint failures. The cured liner is highly durable — most manufacturers rate it for 50+ years — and the smooth interior actually improves flow compared to corroded or root-damaged originals.

Why It Works Well for Older Homes

Older Ottawa homes — particularly those built before the 1970s — commonly have clay tile, cast iron, or Orangeburg pipe (a tar-and-felt material that deteriorates badly over time). These materials crack, root-infiltrate, and collapse as they age. Relining is ideal when the pipe structure is still mostly intact but suffering from cracks, joint separation, or root damage. It avoids tearing up finished basements, landscaping, driveways, or mature trees — a major advantage in established Ottawa neighbourhoods.

When Relining Isn't the Right Answer

Relining has real limitations. If a pipe has collapsed sections, severe misalignment, or significant bellying (low spots where water pools), a liner won't fix the underlying structural problem. A camera inspection is essential before any relining decision — it tells you exactly what you're dealing with. Pipes that are too deteriorated, or those with multiple 90-degree bends, may not be good candidates.

Ottawa-Specific Context

In Ottawa, pipe relining typically costs $150 - $250 per linear foot, making it competitive with or cheaper than full excavation once you factor in landscaping restoration, concrete cutting, and backfill. For a typical residential sewer run, expect a project in the $3,000 - $8,000 range depending on length and access. Permit requirements may apply — confirm with your licensed plumber and Ottawa Building Services.

Your Next Step

The single most important thing to do before committing to any pipe repair strategy is a camera inspection. It removes the guesswork entirely and gives you a documented picture of what's happening underground. If you're in an older Ottawa home with slow drains, recurring backups, or sinkholes forming in your yard, that's a strong signal your sewer line deserves a look.
