Sometimes unblocking isn't enough. If your drains are damaged, collapsed, or suffering from ongoing issues, a repair is often the only long-term solution. At Happy Drains, we diagnose the problem properly and carry out the most effective repair — restoring your drainage system quickly and reliably.
Drains can fail for a number of reasons, including ground movement, root ingress, wear and tear, or poor installation. Left untreated, these issues can lead to repeated blockages, leaks, or even full collapse.
We provide fully guaranteed drain repairs, tailored to the condition of your system and the most practical solution for your property.
Where possible, we use modern no-dig repair technology, including Cured-In-Place Pipe (CIPP) lining. This method allows us to repair damaged pipes internally without excavation by installing a structural liner inside the existing pipe.
In more severe cases, such as collapsed drains or heavily damaged sections, excavation may be required. Our team carries out full excavation and replacement works, including:
We always aim to minimise disruption and restore the area to the highest standard once repairs are complete.
We don't take a one-size-fits-all approach. Every job is assessed properly, and we'll recommend the most suitable option — whether that's a targeted no-dig repair or a full excavation.
You'll receive clear advice, transparent pricing, and a solution designed to last.
We carry out a CCTV survey to identify the exact location, type and extent of the damage.
We explain the options — no-dig relining, patch repair, or excavation — and provide a fixed quote for the agreed approach.
Our engineers complete the repair using professional-grade materials and equipment, minimising disruption to your property.
A final CCTV survey confirms the repair is watertight and the drain is flowing correctly.
Happy Drains is independently vetted, monitored and approved by the UK's leading trade bodies and trust schemes.
Repair costs vary with the type and extent of damage. Small patch repairs and CIPP lining are typically far cheaper than full excavation. Every repair is quoted with a fixed, upfront price after a CCTV survey confirms the scope of work — no surprise extras.
Yes, in most cases. We use no-dig CIPP (Cured-In-Place Pipe) lining and patch repairs that fix damage internally — no excavation, no disruption to driveways, gardens or paving. Excavation is only used when the pipe has fully collapsed or moved out of alignment.
A patch repair or short liner is usually completed in a single day. Longer relining jobs and excavation works typically take 2–3 days depending on access and reinstatement requirements.
Yes. All our repairs are fully guaranteed, and we provide a final post-repair CCTV survey so you have video evidence that the work is watertight and the drain is flowing correctly.
Many home insurance policies cover damage from collapsed drains and root ingress, especially under accidental damage or buildings cover. We can provide CCTV evidence, written reports and itemised quotes suitable for insurance claims.
Yes. Since the 2011 transfer of private sewers, shared drains beyond your property boundary are usually the responsibility of the water company — but we can survey and repair any drainage within your boundary, and advise you on what falls to the utility.
