The ground here is London clay, which swells and shrinks with the seasons and has spent ninety years nudging Osterley's pipe joints apart. A survey shows the displaced joints before they collapse, and it is the sensible first step before any extension is built over the run.
A CCTV drain survey is exactly what it sounds like: we put a camera down your drains and watch, in glorious detail, what four decades of plumbing decisions look like from the inside. To be clear, we would do this bit for free. It’s the best television in the trade. Narrating a drain run like a nature documentary (“here we see the fatberg in its natural habitat”) is a professional perk.
What you get is the useful part: a plain-English report of exactly what’s down there, where it is, and what (if anything) actually needs doing. No jargon without translation, no invented “urgent works”. If the drain is healthy, the report says so.
When a survey earns its money:
- Repeat blockages. If the same drain keeps blocking, something structural is causing it: roots, a dropped joint, scale, or a slumped section. The camera finds the cause, so you stop paying to treat the symptom.
- Buying a house in the TW area. Much of the local stock has original clay drains from the Victorian era or the 1930s. A £250 survey before exchange can save you a £3,000+ excavation after. Lenders and insurers increasingly ask for one.
- Landlords and letting agents. A dated survey report is clean evidence of drain condition between tenancies.
What it costs: a standard domestic survey runs £150–£350 depending on how much drain there is to inspect, and homebuyer surveys with a full written report start around £250. Fixed price, agreed before we start. If the survey finds something that needs fixing, the survey fee is credited against repair work we do, so you never pay twice to learn the same fact.
What to do right now in Osterley
- A survey is a planned visit, not an emergency. If water is actually backing up right now, call us about the blockage first.
- Have a rough idea where your manholes or inspection covers are. If you don't know, that's fine, finding them is part of the job.
- Buying a house? Book the survey before exchange, not after. A collapsed drain is the buyer's problem the moment you own it.
CCTV Drain Survey help, local to Osterley
A 1930s suburb on heavy clay: salt-glazed runs under long gardens, and a park full of trees next door.
Osterley is the leafy 1930s corner of TW7, laid out around the Piccadilly line station with the park on one side and the Great West Road on the other. The houses are consistent, the gardens are long, and the drains are salt-glazed clay runs that travel the length of those gardens before they find the sewer. That geometry is the whole story: twenty metres of shallow pipe gives a blockage plenty of room to hide, and a rod from the gully rarely gets there.
The ground does its bit. Osterley sits on London clay, which swells in wet winters and shrinks in dry summers, and ninety years of that has eased the joints apart. A displaced joint catches debris, lets roots in from the park-side trees and, eventually, drops. The camera shows all three stages clearly, and the earlier we see it the cheaper the fix.
We also get called before building work. A lot of Osterley semis are getting extensions over the original run, and a survey first is far cheaper than a collapsed drain under a new kitchen floor. We cover Osterley from Isleworth and Hounslow, at any hour.
We cover all of Osterley (TW7) — from Osterley Park, Osterley station, the Great West Road and across Isleworth, Hounslow, Brentford. Being genuinely local means we already know what Osterley's drains are made of, and how fast we can be at your door.More about drains in Osterley →
