How much does it cost to unblock a drain?
+
A standard domestic jetting visit across Berkshire is £150–£280 depending on access and how stubborn the blockage is. The number is fixed before we start the work — never on the clock.
Do I need a CCTV survey or just a jet?
+
If it's a one-off blockage with an obvious cause (wet wipes flushed at Christmas), a jet alone is fine. If you've had two or more blockages on the same run, a survey is essential — there's almost always a structural cause underneath.
Are your CCTV reports accepted by insurers?
+
Yes. We grade everything against the WRc Manual of Sewer Condition Classification (the UK industry standard) and provide screenshots, location plans and severity scoring. Every major home insurer accepts our reports.
Can you reline a drain instead of digging it up?
+
In most cases, yes. Patch lining handles defects up to about 1m. Full reline handles entire lateral runs. Excavation is only required where there's total collapse or where the drain is too deformed for a liner to set against.
How long does a drain repair take?
+
Jetting and survey: one visit, typically 90 minutes. Patch liner: same day. Full reline: one day. Excavation and replacement: 2–4 days depending on depth and surface reinstatement.
How long will a drain repair last?
+
CIPP lining has a 25-year design life and 50-year practical lifespan. Excavated and replaced uPVC drainage runs are good for 80-plus years. We guarantee our workmanship for 12 months and the liner materials carry the manufacturer's warranty.
Do you cover commercial drainage?
+
Yes — planned maintenance contracts, emergency response, CCTV surveys, repairs and statutory compliance. Sean built the business off the back of commercial Thames Water subcontracting; commercial drainage is core, not a sideline.
What guarantee do you offer?
+
Every job leaves with a written guarantee — labour is covered by us, and manufacturer warranties on parts and fittings are registered in your name and emailed across with the paperwork. If anything moves, leaks or fails inside the guarantee window, we come back and put it right at no charge.
Are you fully insured?
+
Yes. Overflow Plumbing & Drainage Ltd (Company No. 12427151) carries full public liability and employers' liability insurance. Certificates are sent across with your quote on request — landlords and letting agents usually want them for their files.
