Pest control in Frognal

Frognal sits on the wooded slope below Hampstead, and the tree cover is the whole story. Mature gardens, established canopy and continuous hedge lines give grey squirrels and rats an elevated route that never touches the pavement, and the buildings they arrive at are exactly the kind that reward them: generous roofs, deep eaves, and voids that were built to be ventilated rather than sealed.

What the postcode disguises is how much of this is commercial work. Behind the residential character sit interwar mansion blocks run by managing agents, prep schools and nurseries, consulting rooms and private clinics along Fitzjohn's Avenue, diplomatic and institutional occupiers in converted townhouses, and housing association and council-managed stock a few streets in either direction. Every one of those is a contract with reporting obligations, insurance requirements and a duty holder who needs evidence, not a reassurance on the doorstep.

The pests do not respect that distinction. A squirrel entering a mansion block roof is the same problem as a squirrel entering a house, except that it is now the agent's liability, the residents' committee's agenda item and, if it reaches a cable run, an insurance claim. Blocks also concentrate what individual houses only hint at: communal bin stores, shared loft space over multiple flats, and roofs whose parapets and valley gutters carry pigeon nesting that no single leaseholder will ever pay to remove.

Nightshift has been treating buildings of this age for over forty-five years, and the specialist trades matter more here than in most of London. The same survey that deals with a squirrel in a roof void is often the one that identifies an old woodworm flight-hole pattern in a rafter, a damp bearing end, or a gable that needs proofing rather than another visit. Our timber division has been preserving historic timber for over forty years and issues twenty-year warranties on its work. Technicians answer 24 hours a day, and a survey costs nothing.

The building stock

Large Victorian and Edwardian detached and semi-detached houses in generous plots, many with later loft conversions, tile-hung gables and deep timber eaves, alongside interwar mansion blocks in multiple occupation, converted townhouses in institutional, school and clinical use, and a scatter of substantial modern replacements on the older garden plots.

Where the pressure comes from

Common hotspots

• Roof voids, eaves cupboards and dormer cheeks
• Soffit vents, fascias, bargeboards and lifted ridge tiles
• Communal bin stores, refuse areas and porters' cupboards
• Parapet gutters, valley junctions and pigeon-nesting ledges on block roofs
• Cold-water tanks and pipe runs in the loft
• Cellars, coal chutes and under-stair voids
• Garden outbuildings, log stores and compost heaps
• Boundary hedging, ivy-covered walls and mature tree canopy
• Wool carpets, wardrobes, communal stair carpet and stored textiles
• Structural timber, rafters and floor joists

Questions we are asked in Frognal

We manage a block here. Do you contract with the agent or the residents?

With whoever holds the building. As standard we contract at block level with the managing agent or freeholder, attend communal areas on a scheduled programme, and issue the written report the same day. Where a leaseholder needs their own evidence for an insurer or a dispute we can supply flat-level detail separately.

Something is running about above the top-floor ceiling. Squirrel or rat?

The timing is the clue. Squirrels are heavy, distinct and busiest around dawn and dusk; rodents are lighter and are heard through the night. We identify it on survey from droppings, gnawing pattern and the entry points, because the treatment and the proofing differ, and in a block the cable runs make getting it right the difference between one visit and a claim.

Do you hold contracts for schools, nurseries and clinics?

Yes. Those sectors need documentation as much as treatment, so RAMS, COSHH data, insurance certificates and risk assessments are supplied for the file, technicians are DBS checked where the setting requires it, and visits are scheduled around the hours children or patients are on site. We are BPCA members and CEPA certified.

Will you find how they are getting in, or just remove them?

Both, and the second matters more. A roof that is not proofed is re-entered, usually within the same season. We survey the whole elevation, including the parts only visible at height, and repair the fabric so the route is closed.

Can you deal with a wasp nest in a third-floor gable?

Yes. Work at height is routine for our teams and we supply our own access equipment, so a nest in a soffit or behind a bargeboard is treated from a safe, stable position rather than off a ladder.

We are buying a house on this road. Can you inspect the timber first?

Yes. We carry out prior-purchase Home Buyers Surveys for woodworm, rot and damp, which in buildings of this age and this much roof structure is worth doing before exchange rather than after. Our timber team has been preserving historic timber for over forty years and issues twenty-year warranties on its work.
