How Pipe Relining Can Save You Time and Money

Buried pipes don’t give you much warning before they fail. One day, your drains are working fine, the next you’re facing a flooded yard and a quote for $15,000 worth of excavation work. But here’s what most property owners don’t know: traditional underground pipe repair doesn’t have to mean tearing up your entire property.

Pipe relining offers a faster, less disruptive alternative that can fix damaged pipes from the inside, without the need to dig up your driveway, landscaping, or concrete slab. Plus, the financial benefits extend well beyond simply avoiding excavation costs.

Quick Answer

• Underground pipe repair through relining costs 25-30% less than traditional dig-and-replace methods when you factor in restoration costs
• Completion time is hours, not weeks – most residential jobs finish in a single day
• 50-year lifespan – relined pipes last as long as brand new pipes
• No property damage – your driveway, garden, and structures stay intact
• Works for multiple pipe types – sewer, stormwater, and drainage pipes

What Is Pipe Relining?

Think of pipe relining as creating a brand new pipe inside your old, damaged one. A flexible liner coated with epoxy resin is inserted into the existing pipe, inflated to press against the pipe walls, then cured to form a hard, durable new pipe within the old structure.

The process is surprisingly straightforward:

1. First, plumbers run a CCTV camera through your pipes to pinpoint exactly where the damage is, so there is no unnecessary work.
2. Second, high-pressure water jets clean out any debris, tree roots, or blockages that might interfere with the liner.
3. Third, the resin-saturated liner gets pulled or inverted into position. Once it’s in place, it’s inflated and left to cure – usually taking just a few hours.
4. Finally, another camera inspection confirms everything’s sealed properly and working as it should.

The result is a seamless, jointless pipe that’s resistant to corrosion, tree root intrusion, and the usual wear and tear that damaged your original pipes.

The Real Cost of Traditional Underground Pipe Repair

Before we get into how much you’ll save with relining, you need to understand what traditional pipe repair actually costs.

Traditional excavation for underground pipe repair typically runs $400-500 per linear foot, with total projects ranging from $7,500 to $30,000 for 20-30 feet of pipe. But that’s just the pipe work itself.

Add in:

• Excavation and trenching labour
• Removing and disposing of old pipes
• Traffic management if pipes run under roads
• Restoring landscaping, driveways, or concrete after the dig
• Lost business revenue if you need to close during repairs

City ordinances typically require trenches 24-36 inches deep for water or waste pipes, which means removing massive amounts of soil and destroying everything above it. Your landscaping? Gone. That new driveway you poured last year? Needs replacing.

And here’s the kicker: it can take well over a month for sod to take root on a lawn after excavation work, so you’re looking at a torn-up property for weeks.

How Pipe Relining Cuts Your Costs

Modern pipe repair solutions like relining flip the equation entirely. Trenchless pipe relining costs roughly 25-30% less than traditional excavation when you account for all restoration expenses, and that’s before you factor in the time savings.

Here’s why the numbers work in your favour:

• Minimal excavation means minimal restoration. Plumbers only need access points at either end of the damaged section – usually existing manholes or small access pits. No trenches running the length of your property. No destroyed landscaping. No concrete replacement bills.
• Labour costs drop dramatically. Without heavy machinery and extensive manual digging, labour hours get slashed. The job that would’ve taken a crew two weeks with excavators? Done in a day with relining equipment.
• One fix, not multiple repairs. The seamless epoxy liner eliminates weak points where future leaks typically develop. You’re not patching a problem, you’re solving it completely.

Time Is Money (And Pipe Relining Saves Both)

If you’re a business owner, every hour your premises are unusable costs you money. For homeowners, it’s the inconvenience factor of having contractors on-site for weeks.

Most residential pipe relining jobs are completed in just a few hours to a single day, compared to several days or weeks for traditional methods. When you’re not digging, moving soil, and reconstructing everything afterwards, the timeline compresses massively.

For commercial properties, this speed difference is crucial. A restaurant can’t close for three weeks while you dig up their car park. A factory running 24/7 can’t shut down production lines. Trenchless relining allows businesses to maintain operations with minimal disruption.

Why Underground Pipe Repair Matters for Different Pipe Types

Stormwater Pipe Relining

Stormwater pipes are crucial for managing excess rainwater and preventing flooding, but they often fail due to age, environmental conditions, and the intrusion of tree roots.

Traditional stormwater pipe relining required closing roads, digging up footpaths, and causing major traffic disruptions. Modern pipe repair solutions approach the issue differently. Stormwater pipe relining restores the structural integrity of pipes while eliminating infiltration and exfiltration that cause erosion around your property.

The smooth interior surface created by relining also improves water flow capacity – meaning your stormwater system handles heavy rainfall more effectively than before the repair.

Sewer and Drainage Pipes

Blocked sewer lines don’t just smell terrible; they pose genuine health risks and can cause extensive property damage if sewage backs up into your building.

Pipe relining creates a root-proof barrier inside your sewer pipes. Tree roots that were infiltrating through cracks and joints? They can’t penetrate the seamless epoxy liner. That means fewer blockages, less frequent maintenance, and no more emergency plumbing callouts at 2 am.

The 50-Year Investment

Let’s talk longevity. Properly installed pipe relining systems last 50+ years – comparable to completely replacing pipes with new materials, but at a fraction of the cost and disruption.

The epoxy resin used in modern relining is engineered to resist everything that destroyed your original pipes: corrosion, chemical exposure, abrasion from flowing water, and temperature extremes. The new lining is resistant to issues like corrosion, leaks, and tree root intrusion.

Compare that 50-year lifespan to spot repairs or temporary fixes that might only buy you another few years before the next failure. Several spot repairs and repeated cleanings can exceed the cost of a one-time relining, while causing recurring disruptions.

When Pipe Relining Makes Sense

Not every pipe problem suits relining. It works brilliantly for:

• Cracked or leaking pipes that still maintain their basic shape
• Root-damaged sewer or stormwater lines
• Corroded cast iron or clay pipes
• Pipes under driveways, buildings, or landscaped areas where excavation would be costly

However, pipes that have completely collapsed or are extensively damaged may require traditional replacement. A residential plumber can assess your specific situation with a camera inspection and recommend the most cost-effective option.

The Bottom Line on Savings

Here’s the maths that matters: a 20-metre underground pipe repair job using traditional excavation methods might cost $12,000 – $15,000 once you factor in all the restoration work. The same job with pipe relining? Typically $6,000 – $10,000, completed in a fraction of the time, with zero property damage.

Over a 50-year lifespan, you’re looking at potentially decades without needing another repair. No recurring maintenance costs, emergency callouts or disruption to your property or business operations.

For commercial properties, adding the cost of lost business during extended repairs makes relining even more financially compelling.
