CCTV Survey in Caernarfon

Caernarfon's combined sewerage system means foul and surface water share the same pipe — increasing risk during heavy rainfall. With 36% of properties built before 1920, most homes in LL55, LL56, LL57 and LL58 contain salt-glazed clay drainage or lead-solder copper joints. CCTV inspection pinpoints root ingress, pipe collapse, and joint failure before they cause expensive blockages.

CCTV drain surveys in Caernarfon (LL55–LL58) provide high-definition video inspection of underground drainage systems, identifying blockages, root ingress, pipe damage, and corrosion in Victorian clay pipework. Reports with WinCan and OS1 coding are accepted by mortgage lenders and property insurers.

Drainage in Caernarfon — what local engineers know

Welsh Water supplies Caernarfon through slightly acidic soft water that accelerates corrosion of older copper fittings and lead joints — a common issue in Gwynedd properties. Combined sewerage infrastructure means blockage surcharge risk during heavy rainfall, affecting both foul and surface water. The majority of Caernarfon's pre-1920 properties rely on salt-glazed clay drainage prone to root ingress and structural collapse. CCTV surveys are particularly valuable for pre-purchase checks in these older areas, and for diagnosing stubborn blockages that don't respond to conventional rodding.

  • Soft water supply reduces limescale, but slightly acidic pH can accelerate corrosion of copper fittings and lead joints in older Caernarfon properties
  • Combined sewerage infrastructure — common in older parts of Caernarfon — means foul and surface water share the same pipe, increasing surcharge risk during heavy rainfall
  • Ageing infrastructure in parts of Caernarfon means drain blockages from grease, wipes and root ingress remain the most common call-out reasons
  • With 36% of properties built before 1920, salt-glazed clay drainage and lead-solder copper pipework are common — pipe collapse, root ingress and joint failure are recurring call-out drivers.

Who's responsible for drains in Caernarfon?

In Caernarfon, responsibility for a blocked or damaged drain depends on where the fault sits. As a homeowner you are responsible for the drains within your property boundary that serve only your home. Since the 2011 private sewer transfer, Welsh Water is responsible for shared sewers and lateral drains beyond your boundary — even where they run under private land. Road gullies and highway drainage are maintained by Gwynedd.

This matters because it determines who pays. If our engineer's CCTV inspection shows the fault is in a shared sewer, we'll tell you — and you can report it to Welsh Water rather than paying for the repair yourself. The combined sewer layout that dominates Caernarfon affects where these boundaries typically fall, and our local engineers know the LL55, LL56, LL57 networks well enough to identify ownership quickly.

CCTV Survey prices in Caernarfon

Every Caernarfon job is quoted as a fixed price before work starts — what we quote is what you pay, with no call-out fee for providing the quote. However, the final price depends on access (an external inspection chamber is quicker than internal-only access), the pipe material and condition , and how established the blockage or fault is. Request your free quote and we'll confirm the price and your engineer's ETA in the callback.

In summary, CCTV Survey in Caernarfon is backed by a 12-month workmanship guarantee. Furthermore, every job includes a written completion report. Consequently, you have full documentation if the same fault recurs.

Illustrative example of typical work

Root ingress in Victorian clay drain, LL55 terraces

Area:
Caernarfon
Service:
CCTV Drain Survey

A 1880s terrace in LL55 experienced recurring autumn blockages traced to tree roots penetrating salt-glazed clay joints. CCTV revealed multiple fractures extending 8 metres into the main drain run. The homeowner had the affected section replaced before purchase, identified from the video report and colour stills provided.

This describes typical work performed by engineers in our network. Names and specific details have been omitted to protect customer privacy.

CCTV Survey in Caernarfon — FAQs

Why do Caernarfon's older properties have so many drain blockages?
36% of homes were built before 1920 using salt-glazed clay pipes and lead-solder joints. These materials fail through root ingress, joint corrosion (especially in Caernarfon's soft water), and simple age. Combined sewerage also means blockages can affect foul and surface water simultaneously during rainfall.
Does soft water in Caernarfon damage plumbing?
Welsh Water's supply is slightly acidic, which accelerates corrosion of copper fittings and lead solder joints common in older Caernarfon properties. Acidic water dissolves the protective oxide layer on copper, leading to pinhole leaks and joint failure — CCTV inspection helps identify risk before failure occurs.
How much does a CCTV drain survey cost?
A standard residential pre-purchase survey is a fixed fee that includes the footage, written report and recommendations. Larger commercial surveys are quoted per site.
Do I need a survey before buying a house?
If the property is over 30 years old, has mature trees nearby, or sits on clay pipework, a pre-purchase CCTV survey is strongly recommended and often cheaper than a single future repair.
What's in the report?
A WinCan-compliant PDF with every defect graded, a pipe-run plan, photo stills of each issue and a plain-English summary of what (if anything) needs attention.
Will it identify insurance-claimable damage?
Yes. Our reports are widely accepted by UK insurers and loss-adjusters as evidence for claims involving ingress, collapse or tree-root damage.
