When it comes to fixing damaged drains in Portsmouth, homeowners often face a key question — should you go for a CIPP patch repair or a full drain lining? Both methods are modern, no-dig solutions that eliminate the need for excavation, but they differ in cost, coverage, and lifespan.
Let’s explore which option fits your property’s drainage system and how to make the right choice for lasting results.
🔍 Understanding CIPP Drain Lining
Cured-in-Place Pipe (CIPP) lining is a trenchless technology that rehabilitates old, cracked, or leaking drains by inserting a resin-coated liner into the existing pipe. Once cured with hot water or UV light, it forms a new structural pipe within the old one — restoring flow and preventing leaks.
This technique is ideal for Portsmouth homes with aging clay or pitch fibre pipes, especially where digging would be disruptive or costly.
Benefits of Full CIPP Lining
- Complete coverage: Reinforces the entire pipe length
- Long-term durability: Typically lasts 50+ years
- Prevents further collapse: Creates a seamless watertight barrier
- Minimal disruption: No excavation or garden damage
⚙️ What Is a CIPP Patch Repair?
A patch repair is essentially a smaller version of full lining. Instead of relining the entire pipe, a short liner (usually 1–2 metres long) is applied to repair a specific damaged section.
This is ideal for isolated cracks, joint displacements, or small root intrusions — without the cost of relining the full run.
Benefits of Patch Repairs
- Cost-effective: Only treats the problem area
- Fast installation: Usually completed in under two hours
- No disruption: Perfect for small residential properties
- High precision: Targets known defects without over-relining
💡 Patch Repair vs Full Lining — Key Differences
| Feature | CIPP Patch Repair | Full CIPP Lining |
|---|---|---|
| Coverage | Localised (1–2m section) | Entire pipe run |
| Best For | Isolated cracks, displaced joints | Widespread or recurring damage |
| Cost | Lower (targeted repair) | Higher (full system) |
| Durability | 15–25 years | 40–50+ years |
| Installation Time | 1–2 hours | Half day (average) |
| Disruption | None | Minimal |
Both methods are trenchless, but full lining offers more structural reinforcement, while patch repairs are ideal for quick, budget-friendly fixes.
🧰 When to Choose Each Option
✅ Choose Patch Repair When:
- The defect is minor or localised
- A CCTV survey identifies one or two problem spots
- You’re managing a smaller repair budget
- The rest of the pipe is structurally sound
✅ Choose Full Lining When:
- Multiple cracks or collapses are detected
- The pipe is deteriorating throughout its length
- You want a long-term fix with warranty cover
- You’re renovating or upgrading property drainage

Common Causes of Damage Found in Portsmouth Drains:
- Tree root intrusions near gardens and pavements
- Pipe corrosion from salty coastal air
- Old pitch fibre pipe deformation
- Ground movement from nearby construction
🌧️ Why No-Dig Repairs Are Perfect for Portsmouth
The city’s compact streets and historic buildings make traditional excavation nearly impossible without disrupting traffic or damaging property foundations. Trenchless lining and patch systems are the ideal choice for:
- Period homes near Southsea and Old Portsmouth
- Modern estates with limited access
- Coastal properties where soil is unstable
CIPP Drain Repair FAQs
How do I know if I need a patch or full lining?
A CCTV survey reveals the extent of damage. Localised cracks usually need a patch; widespread damage requires full lining.
How long does CIPP lining last?
A properly installed full liner can last up to 50 years or more, offering a long-term solution for Portsmouth homes.
Will I need to dig up my garden?
No. Both methods are trenchless and carried out through existing access points like manholes.
How much does CIPP drain lining cost in Portsmouth?
Patch repairs start around £250–£400, while full lining can range from £900–£2,000 depending on the length and diameter.
Can CIPP lining stop root intrusion?
Yes. Once lined, the new pipe is fully sealed, preventing roots from entering in the future.
