Trenchless pipe relining to repair damaged drains without excavation — ideal for London's busy streets.
Free, no-obligation — we'll call you back fast.
Pipe relining — also known as CIPP (cured-in-place pipe) relining — is the most cost-effective method for repairing cracked, root-infiltrated, or joint-displaced drains in London properties without excavation. A flexible resin-impregnated liner is inserted into the existing pipe and inflated against the pipe walls. The resin cures to form a new, smooth, root-resistant bore inside the old pipe, sealing all defects and restoring full pipe capacity. Furthermore, pipe relining carries a 50-year design life, making it directly comparable to full pipe replacement in longevity but at a fraction of the cost and disruption. In addition to its cost advantages, relining is often the only practical option for drainage running beneath listed buildings, paved courtyards, mature gardens, or shared rear access lanes. Therefore, conservation-area homeowners and freeholders of period London terraces increasingly choose relining over excavation when CCTV surveys identify failing pipework. As a result, we have relined hundreds of metres of Victorian clay drainage in central London boroughs without disturbing a single paving slab. That said, relining requires a structurally sound host pipe — if a section has fully collapsed or deformed beyond a certain limit, excavation is the only safe option, and we will tell you straight if that is the case rather than waste money on a liner that cannot succeed. Every relining job concludes with a post-installation CCTV check and a written guarantee.
CCTV survey to confirm pipe condition and measure the defect section
Drain jetted thoroughly to prepare the pipe surface
Resin-impregnated liner prepared to the correct length and diameter
Liner inserted and inflated against the pipe wall
Resin cures in place (2-4 hours typical)
Post-relining CCTV survey to confirm the repair
Written guarantee documentation issued
Pipe relining costs in London typically start from £800-£1,200 for a 3-5 metre spot repair. Full-length relining of a complete drain run (8-15 metres) costs £1,500-£3,500 depending on pipe diameter and accessibility.
A standard pipe relining job in a London property takes 4-8 hours, including the pre-relining jet clean, liner installation, curing time, and post-relining CCTV check. Larger jobs may take 2 days. No excavation means minimal disruption to your property.
Yes. CIPP relining is specifically designed for installation in existing clay, cast iron, and concrete pipes — the pipe types found in London's housing stock. The liner is flexible enough to negotiate bends and junctions, and the cured resin bonds securely to the existing pipe wall.
