The World’s most beautiful, vibrant city

We declare a bias.

It rains most weeks, mainly at night, keeping our gardens green, air fresh and winter’s mild.

Railways, the internet of it’s time

Robert Hichens was chairman of the London Stock Exchange between 1838 and 1842 precipitating a period of massive investment and construction of the railways. London suburbs became commutable and desirable with fresher air than central London.

The Great Stink

The Great Stink of July to August 1858 was caused by untreated human waste along the banks of the River Thames. It resulted in Joseph Bazalgette’s 82 mile sewage system.  By 1866 most of London was connected to the sewer network.

Flush toilets

Ability to connect flush toilets to the network, was one of the many benefits. Standard Victorian London house designs moved away from the split ground floor (lower and raised) to incorporate a flush toilet on the ground floor and bedroom level. The change in design meant that properties were often closer to roads. In these pre-car days, streets were covered in manure which would splash onto walls, with consequential ingress of odorous moisture.

Damp proof course

A by-law was introduced in 1877 in London requiring a damp-proof courses (“DPC”) “beneath the level of the lowest timbers”. It was not introduce to combat rising damp. London has never had a problem of high water table. In areas of the country where there is a high water table issue, a sacrificial trench was dug around a property, filled with gravel and drained away from a property.

Flood protection

According to Thames Water, London’s water-table is low, below the lowest tube-line.  Almost every property in London is in a low flood risk area (see flood risk checker– flood risk is a proxy for a high water table, a necessity for rising damp). If the water table is well below ground floor level, the risk of rising damp is low.

Damp Treatment Fails

Yesterday we surveyed two properties both with damage caused by a large chemical damp proofing company. Here’s a snippet of the Plc’s failures.

Misdiagnosis condensation, as penetrating damp through chimney

Damp Surveys – problem damp in lower ground floor flat Misdiagnosis An independent surveyor missed the obvious signs of condensation. Sad, because you expect contractors to misdiagnose damp, after all “they are incentivised to sell”. A cold November day, 4 people living in a two bedroom lower ground floor flat, no extractor fan in kitchen nor bathroom …
