Pipe relining is a trenchless repair method that fixes a damaged pipe from the inside, without digging up your yard, driveway, or foundation. A plumber inserts a flexible, epoxy-resin-coated liner into the existing damaged pipe, then cures it in place — using hot water, steam, or UV light depending on the method — so it hardens into a smooth, seamless new pipe within the old one. The result is a structurally sound pipe with a lifespan of 50+ years, installed in a fraction of the time and disruption of traditional excavation. It works on sewer lines, drain pipes, water mains, and lateral pipes running between the house and the street connection, which is why it's become the preferred repair option for cracked, root-intruded, or corroded pipes across the US. In 2026, pipe relining typically costs $80 to $250 per linear foot, with most residential projects totalling $3,500 to $14,000. This guide breaks down exactly what drives that price, the different relining methods available, and how it compares to full pipe replacement.
"Pipe relining costs more upfront than a patch repair but significantly less than full excavation once you factor in driveway restoration, landscaping, and concrete reinstatement. Get a camera inspection first — it confirms whether relining is actually suitable for your pipe condition. Not every damaged pipe can be relined; if there's a full collapse or major offset joint, replacement is the only option."
Average Pipe Relining Cost in 2026
The table below summarises the most common pipe relining costs in 2026, from a small residential job through to large or emergency projects.
| Cost Item | Cost Range |
|---|---|
| Per linear foot (CIPP standard) | $80 – $250 |
| Small residential project | $4,500 – $6,500 |
| Typical residential project | $3,000 – $12,000 |
| Mid-range project (120ft) | $9,000 – $16,000 |
| Large/complex project | $12,000 – $20,000+ |
| Camera inspection (required first) | $125 – $400 |
| Hydro jetting (pre-reline clean) | $300 – $600 |
| Traditional replacement (comparison) | $3,000 – $25,000 |
| Emergency pipe relining | $5,000 – $18,000+ |
Most homeowners pay $9,000–$12,000 for a typical residential pipe relining project — well within the broader $3,500–$14,000+ range. Per-foot pricing usually runs $80–$250 for standard CIPP relining, with larger or more complex jobs pushing toward $260–$300 per foot.
Cost Per Linear Foot — What You're Actually Paying For
Pipe relining is priced primarily by the linear foot, since the length of pipe being relined drives most of the material and labour cost. CIPP (cured-in-place pipe) relining, the most common method, typically runs $80–$250 per linear foot, with pricing varying by pipe diameter.
| Pipe Diameter | Cost Per Linear Foot |
|---|---|
| 3–4 inch (standard residential sewer) | $80 – $150 |
| 6 inch | $100 – $200 |
| 8 inch | $150 – $250 |
| 10+ inch (commercial/municipal) | $200 – $500+ |
Example: a 50ft residential sewer line relined at $120/ft comes to $6,000. A longer 100ft run at $150/ft totals $15,000.
Tip: always ask for a per-foot quote AND a total project quote. Having both makes it far easier to compare bids between contractors and spot anyone padding the price with vague "additional materials" line items.
What Affects the Cost — 6 Factors
Six key factors determine what you'll actually pay for a pipe relining project. Understanding each one helps you budget accurately and avoid surprises once work begins.
1. Pipe Length
This is the single biggest factor in the total cost. Since relining is priced per linear foot, a short 30ft repair section costs a fraction of a full 100ft+ lateral line run from house to street.
2. Pipe Diameter and Material
Larger-diameter pipes require more liner material and longer cure times, pushing the per-foot cost up — from $80–$150 for standard 3–4 inch residential sewer lines to $200–$500+ for 10+ inch commercial pipes.
3. Accessibility
A pipe reachable through an existing basement cleanout is a straightforward job. If the crew needs to dig small access pits to reach the pipe, expect additional labour and equipment costs on top of the relining itself.
4. Extent of Damage
Minor cracks are the cheapest and fastest to reline. Root intrusion requires cutting the roots out first, and partial collapse may need extra reinforcement — all of which add time and cost to the job.
5. Pre-Reline Preparation Needed
Most jobs need the pipe cleaned before the liner goes in. Hydro jetting to clear debris and roots typically adds $300–$600, and heavier root cutting can add further cost depending on severity.
6. Labour Rates by State
Plumbing labour runs $75–$150 per hour nationally, but coastal metro areas typically run 30–40% higher than the national average. See our guide on how much a plumber costs for a broader look at regional labour rates.
Pipe Relining Methods and Their Costs
Several trenchless methods fall under the "pipe relining" umbrella, each suited to different pipe conditions and budgets.
CIPP — Cured-in-Place Pipe ($80–$250/linear foot) — the most common method. An epoxy resin liner is inserted into the damaged pipe and cured using hot water, steam, or UV light, forming a hard new pipe within the old one. Properly installed CIPP liners last 50+ years.
Pull-in-Place Lining ($100–$250/linear foot) — a pre-made liner is pulled through the damaged pipe and then inflated against the pipe walls. This method works well for shorter, straighter runs where a pull-through liner can be threaded easily.
Internal Pipe Coating / Epoxy Spray ($50–$150/linear foot) — a thin epoxy layer is sprayed inside the pipe rather than inserted as a liner. It's best suited to water mains and smaller-diameter pipes with only minor deterioration, since the thinner walls aren't suitable for severely damaged pipes.
Pipe Bursting ($60–$200/linear foot) — technically a replacement method rather than relining. A bursting head breaks apart the old pipe while simultaneously pulling a brand new pipe through in its place. It's the right choice when a pipe is too damaged for relining but excavation still isn't desirable.
Pipe Relining vs Full Replacement
Relining and full replacement solve the same underlying problem in very different ways. Here's how they compare across the factors that matter most.
| Factor | Pipe Relining | Full Replacement |
|---|---|---|
| Cost | $3,500 – $14,000 | $3,000 – $25,000 |
| Disruption | Minimal — no digging | Major excavation |
| Time | 1–2 days | 3–5 days+ |
| Driveway/lawn restoration | Not needed | $1,000 – $5,000+ extra |
| Lifespan | 50+ years | 50+ years |
| Suitable for | Cracked, root-intruded, corroded pipes | Collapsed or fully failed pipes |
Tip: pipe relining is almost always cheaper than replacement when you factor in restoration costs. Get quotes for both and compare the true all-in cost — not just the headline repair price — before deciding.
What the Process Involves — Step by Step
A pipe relining project follows a fairly consistent sequence from diagnosis to final sign-off.
- Step 1 — Camera inspection: a technician runs a camera through the pipe to assess damage and confirm relining is suitable. Cost: $125–$400.
- Step 2 — Hydro jetting: the pipe is cleaned of debris, grease, and roots to prepare the surface for the liner. Cost: $300–$600.
- Step 3 — Liner preparation and insertion: the resin-saturated liner is prepared and fed into the damaged pipe section.
- Step 4 — Curing: the liner is cured in place using hot water, steam, or UV light depending on the method used, hardening it into a new pipe wall.
- Step 5 — Final camera inspection: a second camera pass verifies the liner has cured correctly and the pipe is fully sealed.
Total time: 1–2 days for most residential projects.
Tip: reputable companies always show you the pre and post camera footage — insist on seeing both. It's the clearest way to confirm the work was actually needed and was done correctly.
Signs You Need Pipe Relining
Watch for these warning signs that your pipes may need relining:
- Multiple slow drains throughout the house
- Gurgling sounds from toilets or drains
- Sewage smell in the garden or home
- Soggy patches or unusually green grass above the sewer line
- Recurring blockages despite regular clearing
- Camera inspection shows cracks, root intrusion, or corrosion
- Pipes over 30 years old showing any of the above symptoms
Can All Pipes Be Relined?
Relining isn't suitable for every situation. Here's when it works and when it doesn't.
Yes, relining works for: cracked pipes, root-intruded pipes, corroded or deteriorating pipes, and minor offsets.
No, relining won't work for: fully collapsed pipes, major joint offsets (more than 30%), pipes that have already been relined once, and very short sections under 3 feet.
Always get a camera inspection before agreeing to relining. An unscrupulous contractor may quote relining on a pipe that actually needs full replacement — a proper camera inspection is the only reliable way to confirm which repair your pipe actually needs.

Frequently Asked Questions
How long does pipe relining last?
50+ years with proper installation — comparable to a brand new pipe.
Is pipe relining worth the cost?
Usually yes — especially when factoring in excavation and restoration costs of full replacement; get quotes for both.
How long does pipe relining take?
1–2 days for most residential projects; longer for large diameter or complex runs.
Does pipe relining reduce pipe diameter?
Slightly — the liner reduces internal diameter by 6–10mm, but flow capacity is maintained due to the smoother internal surface.
