Our Birmingham drain repairs service starts with evidence from inside the pipe. A CCTV survey identifies the material, position and extent of the damage before we recommend a trenchless drain repair, local patch lining or excavation. This avoids digging where a no-dig method can restore the pipe and prevents lining a section that has already collapsed. Recurring blocked drains and other drainage problems often point to faults elsewhere in the drainage system, so diagnosis comes before repair. Our jetting, CCTV and repair case study follows that sequence, including the use of different repair methods for displaced joints. We provide professional drainage services and drain repair services across the West Midlands, Warwickshire, and Worcestershire. Unlike general plumbing services, our work is focused on underground drainage systems, CCTV surveys and repairs. From our Birmingham and Solihull bases, our local team of drainage specialists covers homes and commercial properties across Birmingham, Solihull, Coventry, Wolverhampton, and Walsall. We also handle damaged drain-pipe repairs in nearby areas such as Shirley, Knowle, Dorridge and Monkspath. Every fixed-price quote explains the defect, repair method, materials and any surface work before you decide whether to proceed.
CIPP lining can seal a cracked or displaced pipe while it still retains enough shape to support the liner. A local patch covers one damaged section; full drain relining can renew a longer run. Both are installed through an existing access point, so suitable drainage issues can be corrected without lifting a patio or driveway.
A resin-impregnated felt or fibreglass liner is inserted through an existing access point (manhole or rodding eye), positioned over the damaged section, and inflated against the pipe wall. The resin cures in place, typically within a few hours, forming a structural new pipe inside the old one.
Trenchless drain repair is particularly useful beneath block paving, paths and established gardens. It can treat cracks, fractures, displaced joints and local root damage when the pipe has not collapsed. We use this method for suitable homes in areas such as Solihull and Warwick where surface reinstatement can form a large part of an excavation quote.
Our patch-lining products are WRc approved, and the completed liner is checked by camera before the drain is returned to service.
A collapsed drain pipe cannot hold a liner in the correct shape. Excavation may also be needed for severe bellying, several connected failures or a route that must be altered. Our team exposes the affected section, removes the failed pipe and fits suitable new pipework to current building standards.
The quotation identifies the access route, depth, surface finish and length to be replaced. Once the work is complete, we test the flow, inspect the new connections and reinstate the agreed surface.
Excavation is more common in areas with very old infrastructure, the Victorian terraces across Birmingham and the wider West Midlands, mining-subsidence areas around Nuneaton, and historic town centres like Stratford-upon-Avon where some drains are centuries old. We reinstate all surfaces after excavation.
Heavy Mercia Mudstone clay across the region shrinks and swells seasonally, cracking and displacing pipe joints.
Roots force their way into pipe joints seeking moisture, widening cracks and eventually collapsing sections of pipework.
Some post-war pitch-fibre drains deform or blister, while old clay joints can crack or move. The pipe condition, not its age alone, decides the repair.
Former mining areas in Nuneaton, Bedworth, and parts of Dudley experience ongoing ground settlement damaging underground pipes.
These drainage problems can point to a cracked, displaced or leaking pipe. If you notice any of these warning signs, a CCTV drain survey can confirm the issue before it worsens.
Same drain blocking repeatedly despite being cleared, which points to structural damage requiring drain unblocking and repair
Sinks, baths, or toilets draining slowly across the property
Unexplained wet areas in your garden, or soil sinking near drain runs
Persistent drainage odour inside or outside, even when drains are flowing
Rats entering through broken drain sections, a common issue in older areas
Subsidence caused by leaking drains washing away soil beneath foundations
Whether a drain can be relined depends on its remaining shape, material, access and the type of defect shown by the camera. These are the main factors our drainage specialists use when choosing a method:
Where the pipe retains its shape and suitable access is available, no-dig work often avoids excavation. If excavation is required, the camera evidence and quotation explain why before any ground is broken. Our drain relining vs excavation guide compares the methods, costs and typical timelines.
Drain repair costs depend on the defect, pipe depth, access and surface above it. We quote after a camera inspection so the fixed price can state the method, materials and reinstatement included. Patch lining starts from £380 including VAT.
No-dig patch lining
Single localised repair to a cracked or damaged section. Completed in a single visit with WRc approved materials and a manufacturer-backed guarantee.
Full pipe relining (CIPP)
End-to-end relining of a complete drain run. Price depends on length, diameter, number of bends, and access. Quoted after survey.
Excavation and replacement
Full pipe replacement including excavation and surface reinstatement. Price depends on depth, access, surface material, and length of run.
Pre-repair CCTV survey
Full diagnostic survey to identify all damage and determine the best repair method. Required before any repair work begins.
The written quote explains the recommended work, materials and itemised cost. You can review it before deciding, and the survey evidence can be shared with another contractor if you want a second opinion.
If you are considering a claim, check the policy before authorising permanent work. Our guide asks whether drain insurance is worth it and explains the difference between buildings insurance, home emergency attendance and paying for drainage work directly.

Repair costs vary depending on the method, depth, and location of the damage. No-dig patch lining starts from £380 inc VAT, while excavation repairs depend on depth and surface type. We always provide a fixed quote after a CCTV survey with no hidden costs.
No-dig repair (also called patch lining or relining) involves inserting a resin-impregnated liner into the damaged pipe from an existing access point. The liner cures in place, creating a new pipe-within-a-pipe without any need to dig up your garden, driveway, or patio. We use WRc approved materials for all no-dig work.
A no-dig patch repair can be completed in a single day. Excavation repairs typically take 1-3 days depending on the extent of damage, depth, and whether reinstatement of driveways or gardens is required. We will give you a clear timeline before starting.
Yes, we always conduct a detailed CCTV drain survey before quoting for any repair work. This identifies the exact location, extent, and nature of the damage, allowing us to recommend the most appropriate and cost-effective repair method. The survey cost is included in the repair quotation.
Yes. All no-dig repairs use WRc (Water Research Centre) approved materials with a manufacturer-backed guarantee. Our workmanship is also guaranteed. For excavation repairs, we use only high-quality PVC pipes and fittings that meet current building regulations.
Excavation is required when a pipe has completely collapsed, when there are multiple failure points close together, or when the pipe diameter or material makes lining impractical. Some very old stone or timber drains found in historic areas like Warwick and Stratford also require full replacement.
We provide drain repair services across Birmingham, the wider West Midlands, Warwickshire and Worcestershire. Our engineers work from Cofton Hackett and Solihull, and we will confirm the likely attendance time for your postcode when you call.
Often, yes. Cracks, displaced joints and local root damage can usually be repaired with a trenchless patch liner or CIPP lining through an existing access point. A fully collapsed, badly deformed or bellied pipe may still need excavation. The camera survey shows which option is suitable.
Our engineers carry equipment for multiple drainage tasks, so we can often handle several issues in a single visit.
