Drain Surveys and CCTV Inspections in Wiltshire and Surrounding Areas

Rats that keep coming back however many times they’re treated, scratching under the kitchen floor, droppings behind the bath panel with no obvious way in. Very often the answer is underground: a cracked pipe, a broken joint or an old drain nobody knew was there. Wiltshire Pest Services Ltd carries out CCTV drain surveys and smoke tests for homes and businesses across Wiltshire and into the borders of Somerset, Dorset and Hampshire, to find exactly where pests are getting in. Call us on 07711 259749 or use the form on this page to book a survey.

Why Drain Surveys Matter for Pest Control

Rats Use Damaged Drains to Get In

Rats live and travel in sewers and drains. A crack, a displaced joint or an uncapped pipe gives them a route into wall cavities, under floors and into your home.

Treatment Alone Won’t Last

If rats are coming in from the drains, clearing the ones inside only makes room for the next ones. Finding and fixing the fault is what stops the problem for good.

Drain Flies and Cockroaches

Drain flies breed in the build-up inside pipes, and oriental cockroaches often come in through damaged drainage. A survey shows where they’re coming from.

Our Drain Survey Services

CCTV Drain Inspections

We send a specialist camera through the drains to see inside the pipes, and record what we find.

Smoke Testing

Harmless smoke is pumped into the drainage system. Wherever it escapes, inside or outside the building, shows a fault that pests could be using.

Finding Disused and Hidden Pipes

Old extensions and renovations often leave pipes that were never capped off properly. They’re a common, hidden route for rats.

Signs You May Need a Drain Survey

Rats Keep Coming Back

If rats return after treatment and you can’t find a way in above ground, the drains are a likely source.

Noises Under Floors or in Walls

Scratching or scurrying under the kitchen or bathroom floor, or inside walls near pipes, often points to a drain fault.

Droppings Near Pipes, Baths or Kitchen Units

Droppings or gnawing around boxed-in pipes, behind bath panels or under kitchen units can mean rats are coming up from below.

Smells or Small Flies Around Sinks

Persistent drain smells or small flies hovering over plugholes can mean a drain problem that’s also attracting pests.

What a Drain Survey Can Find

Cracked and Broken Pipes

Damage from age, ground movement or heavy traffic opens gaps rats can squeeze through.

Displaced or Open Joints

Where pipe sections have moved apart, rats can dig out into the surrounding soil and under the building.

Damaged Inspection Chambers

Broken chamber walls, missing covers or damaged interceptor traps let rats move easily between the sewer and your property.

Tree Root Damage

Roots can break into pipes, cracking them open and creating blockages.

How Our Drain Survey Works

Step 1: Get in Touch

Call us or use the form on this page. Tell us what’s been happening and where. If you call, we’ll take the details and send you a follow-up form through our booking system, then talk you through your options and what happens next.

Step 2: Site Check

We locate the manholes and access points and look at the signs of pest activity, to decide where to start.

Step 3: CCTV Inspection and Smoke Testing

We run the camera through the drains and, where useful, carry out a smoke test to pinpoint exactly where the system is broken.

Step 4: Findings and Footage

We show you what we found, with footage and photos, and explain what it means in plain English.

Step 5: Next Steps

We deal with the pests, and advise on the repairs or proofing needed to close the route off. For businesses, landlords and home buyers, we can provide a written report.

What Affects the Cost of a Drain Survey

We price each survey once we understand the job. The main factors are the size of the property, the length and layout of the drainage, access to manholes, and whether smoke testing or a written report is needed. Get in touch for a clear quote.

Drain Survey FAQs

Can rats come up through drains?

Yes. Rats travel through sewers and can get into buildings through cracked pipes, open joints, uncapped old pipes and damaged inspection chambers. Coming up through a toilet is rare but possible.

What is a drain smoke test?

Harmless smoke is pumped into the drainage system. Wherever it escapes, such as through a crack, a gap under the floor or an old pipe, shows a fault that pests could be using.

Is smoke testing safe?

Yes. The smoke is non-toxic and clears quickly. We’ll let you know what to expect before we start.

What does a CCTV drain survey show?

It shows the inside of the pipes: cracks, breaks, displaced joints, root damage, blockages and signs of rat activity, recorded so you can see it too.

Who is responsible for repairing drains?

In England and Wales, you’re usually responsible for drains within your property boundary that serve only your property. Shared sewers and lateral drains are usually the water company’s responsibility. We’ll tell you what we find so you know who to contact.

Do I get a copy of the footage?

We show you the footage and photos, and can provide a written report for businesses, landlords and home buyers.

How much does a drain survey cost?

It depends on the size of the property, the drainage layout and whether smoke testing is needed. We give you a clear quote before we start.
