Activity has appeared in two flats that share no wall.

That is characteristic of this stock. A century of separate conversions left penetrations through floors, party walls and chimney breasts, so the building is one connected volume however many front doors it has. We inspect the route rather than the two flats, and sealing at each dwelling is what stops it moving.

Nobody seems responsible for the vault. Does that matter?

It matters a great deal, because it is the most common source we find here and the least often inspected. Ownership being ambiguous is not a reason to leave it: we will survey it, report what is there, and state plainly where responsibility appears to sit so the freeholder, the agent and the leaseholders are looking at the same facts.

Squirrels keep getting into the roof.

They are almost certainly arriving along a branch rather than up the wall, so ground-level proofing will not help. The overhang has to be cut back and the roofline details closed. We identify the specific limb and the specific detail in writing, because the two jobs usually sit in different budgets and neither happens without being named.

Can you attend without it being obvious to residents?

Yes, and it is a normal request here. Unbranded arrival, timing planned around occupancy, and reporting that goes only to whoever instructed us. Technicians are on shift through the night rather than called out, so most of the work happens when the building is quiet.

Foxes are getting into the bins every night.

That is a containment problem before it is a fox problem, and it feeds the rodent problem behind it. Bin areas and lightwells that close properly, bins with lids that seat, and no loose bagged waste change this stock more than anything we can place inside the building.

Who should instruct you, the freeholder or the managing agent?

Whoever holds it, and we work to that. What we will always do is survey the whole building including the vault and state where a defect physically sits, so if it falls in the gap between freeholder, agent and leaseholder the report makes that visible rather than leaving it to be argued after the fact.

Above ground the buildings have almost all been divided. A villa built as one household is now four or six flats, and the conversions happened over a century of separate works, each leaving service penetrations through floors, party walls and the original chimney breasts. The result is a building that presents as several homes and behaves internally as one connected volume, which is why activity moves between flats with no shared wall and appears to jump floors.

The third factor is the landscape. Mature street trees, deep front gardens and heavy boundary planting bring the greenery that makes the area what it is, and they also bring squirrels onto roofs by a route that has nothing to do with the ground, and foxes into bin areas nightly. Cutting back an overhanging limb is usually a more effective intervention than anything placed inside the building, and it almost always sits in a different budget.

Nightshift works this stock the way it is actually occupied: the vault and the drainage surveyed rather than the flat that called, proofing specified for period elevations, and attendance arranged discreetly. Technicians are on shift at night, which suits both the residents and the fact that this is when the activity can be seen rather than inferred. Every visit produces a written report the same day.

The building stock

Large Victorian and Edwardian villas and mansion blocks over full-depth basements, many with vaults extending beneath the pavement, almost all subdivided into flats across a century of separate conversions, with penetrations through floors, party walls and chimney breasts, set among mature street trees, deep front gardens and heavy boundary planting, alongside purpose-built blocks of later date.

Where the pressure comes from

The vault under the pavement

Full-depth basements and pavement vaults are dark, damp, rarely entered and connected to public drainage. They are the single most common source we find in this stock, and they are also the space nobody has a clear responsibility for, which is why they are seldom inspected until something upstairs reports. A survey starts here rather than in the flat that called.

A century of conversions, never sealed

Each set of works cut new routes through floors, party walls and chimney breasts, and almost none were closed. The building behaves as one volume however many front doors it has, so activity appears in flats that share nothing. Sealing at each dwelling, floor by floor, is what confines a problem to the flat that actually has it.

Mature planting to the elevation

Street trees and heavy boundary planting bring squirrels to the roof by an aerial route that ground-level proofing cannot address, and give continuous cover to the wall. Cutting back the overhang is the effective intervention and normally belongs to a grounds or highways budget rather than a pest one, which is exactly why it does not happen. We report it in writing with the reason attached.

Bin areas, foxes and the front lightwell

Front lightwells and basement areas collect leaf litter and refuse, and foxes work them nightly, opening bags and spreading waste that then feeds a rodent population. Containment that actually closes changes more here than treatment does, and the condition of those areas is the leading indicator on this stock.

Discretion as an actual requirement

In much of this district the objection to proofing is not technical, it is that it can be seen, and residents would rather a contractor were not obvious either. Unbranded arrival, work planned around occupancy and reporting that goes to whoever instructed it are ordinary requests here and worth agreeing at survey rather than assuming.
