Drain Repairs in Bristol, Bath & the South West

Fast, Reliable, and Long-Lasting Drain Repairs


When drains crack, collapse, or keep blocking no matter how many times they’re cleared, it’s time to look beyond a quick unblock. At Flow Sure Drains, we specialise in drain repairs that actually last — protecting your property, saving you money, and keeping your home or business flowing smoothly.

We’re trusted across Bristol, Bath, North Somerset, and South Gloucestershire for providing fast, no-dig drain repairs, patch lining, and full replacements where needed.

Common Drain Problems We Repair


1. Cracked or Fractured Drains

Small cracks let water escape into the soil, weakening the ground and causing repeat blockages. We can patch line these quickly and cost-effectively.

2. Collapsed Drains

A full collapse blocks the pipe entirely. We’ll diagnose with CCTV, then either re-line or replace the damaged section.

3. Root Ingress

Tree roots love drains. Left unchecked, they cause major blockages and pipe fractures. We cut them out and reinforce the pipe with lining.

4. Displaced Joints

Pipes can slip out of alignment, leaving gaps that trap waste. Patch repairs lock them back together.

5. Repeated Blockages

If you’ve had “the same blockage” more than twice, you’ve probably got underlying damage. A survey and repair stop the cycle for good.

FAQs — Drain Repairs


Do you always need to dig up the garden to repair a drain?
No. In most cases, no-dig patch lining or full lining solves the problem without excavation.

How long does a drain repair last?
A properly installed liner lasts over 50 years. It’s effectively a brand-new pipe inside your old one.

What if my drain has completely collapsed?
If the pipe is beyond lining, we’ll excavate and replace only the damaged section. We keep disruption minimal and surfaces reinstated.

Can you provide evidence for insurance claims?
Yes. Our CCTV surveys come with HD footage and written reports suitable for insurance.

Do you cover landlord and commercial repairs?
Absolutely. We handle repairs for letting agents, shops, restaurants, and offices across Bristol and Bath.

Excavated drain repairs


We sometimes have to carry out excavations as part of our drain repair services in Bristol. This is especially the case if you have collapsed drains, need a replacement drain pipe, or when we are unable to carry out pipe relining solution. Amongst other reasons to excavate include damage from subsidence, severe joint displacements, and large-scale fractures that drain  patching cannot solve.

Once we excavate, we remove the damaged drain pipe and supply and fit new, long-lasting ones. If there is good access on access we may use specialist excavation plant to excavate with minimal disruption.
