Pest control and drainage surveys for property management companies in London

Managing rental properties comes with enough challenges without adding pest infestations into the mix, but in a city like London, where ageing infrastructure meets high-density living, rats, mice, cockroaches and other common pests are never far behind.

At Mercury Pest Control, we specialise in professional pest control for property managers, landlords and block management companies. From rodent control and insect treatments to specialist drain surveys, we provide reliable, rapid solutions that reduce tenant stress and protect your properties long-term.

Whether you manage a portfolio of flats in Clapham or oversee rental homes in Chelsea, we help property professionals stay one step ahead of pest problems.

 

Why property managers need professional pest control

Infestations aren’t just unpleasant, they can damage your reputation, delay lettings, and trigger tenant complaints that take weeks to resolve. However, many infestations don’t start inside the property, they often begin underground.

For example, Rats in particular are using London’s vast sewer and drainage networks to enter homes and flats through hidden weaknesses like:

• Redundant or uncapped pipework
• Displaced drain joints
• Damaged gully traps or soil stacks
• Flexi toilet pan connectors
• Broken manhole chambers after renovations

Without regular inspections or preventative measures, property managers may be unaware of these access points until it’s too late. That’s where we come in.

 

Drainage surveys: the overlooked solution in property pest management

A key service we offer for property professionals is drainage surveys using CCTV camera inspections. Why is this so important?

Because pest control without drain diagnostics is only treating the symptoms, not the cause.

Many rats enter from the sewer system and nest inside wall cavities, floor voids or riser cupboards. If you’re dealing with recurring rat issues, and haven’t yet had a CCTV drain survey carried out, you’re likely missing the root of the problem.

Our drainage survey and pest control process

 

• Step 1: Site assessment – We inspect internal and external areas of the property.
• Step 2: CCTV drain survey – We use HD cameras to explore the full drainage system.
• Step 3: Identify entry points – We pinpoint cracks, redundant lines, and dislodged joints.
• Step 4: Drain jetting (if needed) – Clears blockages to give a full view of any structural issues.
• Step 5: Repairs & proofing – We seal entry points using no-dig technology or fit rat blockers where needed.
• Step 6: Ongoing monitoring – We provide pest reports and follow-up inspections to confirm full resolution.

This approach ensures infestations are dealt with effectively, reducing repeat callouts and unhappy tenants.

Pest control contracts for block management in London

From Wandsworth to Islington, we work with block management companies to provide scheduled pest control that keeps communal areas, risers, bin stores and car parks free from infestations. These locations are high-risk due to:

• Cross-unit travel via pipework and electrical risers
• Refuge areas with food waste or leaking pipes
• Inaccessible lofts or voids where pests go undetected

Our block management contracts include:

✅ Regular pest control visits
✅ Pest proofing recommendations
✅ Emergency call-out response
✅ Digital reporting with photos and actions
✅ Drainage checks on request

Why pest prevention is better than cure

While we’re always here to respond quickly in emergencies, we strongly advise property managers to take a preventative approach. Pest proofing and regular drainage inspections can save thousands in reactive callouts and remedial building works.

Typical proofing measures include:

• Stainless steel mesh over air bricks
• Pest proofing pipework and entry points 
• Relining drains
• Rat blockers in drains
• CCTV surveys after building work or reported rat sightings
