London, known for, St Paul's Cathedral, Coca-Cola London Eye, and Wembley Stadium is also being known as a city that has issues with mould. 

What is mould?

These are microscopic organisms that are challenging to get rid of due to the fact that they are able to grow in carpet fibres, wall cracks, and other difficult to reach areas in the building. The reproductive unit of this fungus is known as spores.

A spore is a microscopic (invisible to the naked eye) reproductive body that has the ability to grow into a new organism, that produces algae, fungi and bacteria. They are regenerative cells that are surrounded by a very tough coating that can survive extreme temperatures, chemicals, bleach and detergents. Most spores are thread-like organisms (filamentous). They stay airborne floating in the air from one room to the next and eventually landing on walls, furniture, woodwork, tabletops, carpeting, clothing and food. Any humid, damp and wet surface becomes a breeding ground for their colonies and production of more of the spores.

Dangerous and harmless moulds can be found almost everywhere in indoor and outdoor environments. They can threaten your health and enter interior structures through cracks, vents, windows and doors. You cannot always see or smell the fungus or their spores and they come in a variety of colours such as green, orange, brown, white or black.

The fungus can reproduce quickly and spread rapidly once it is established inside of a structure. If left untreated, it may weaken or cause tremendous damage to the building's structure and also affect the health of the occupants. Not all spores are harmful to humans and animals. There are 3 types of spore categories:

  1. Allergenic
  2. Hyper-allergenic
  3. Toxic

Mycotoxins are powerful chemicals that are produced by some moulds which have been known to cause illness in people and animals. Individuals react differently when exposed to the mycotoxins which makes it difficult in determining the safe exposure levels for the fungi.

When defining mould, it is very important to distinguish between the ones that you’re able to see on a surface, and spores that can’t be seen with the naked eye but are in the air. The growth you can see on the surface of construction materials has been known to cause damage to properties. The spores that you cannot see with the naked eye that is floating in the air can cause animals and people harm.

How Can I Be Exposed to Mould in Greater London?

Illness from exposure can occur by:

  1. absorption into skin
  2. Ingestion
  3. Inhalation

It is not good to have this fungus growing indoors, but if it’s present, you or your pets are not necessarily exposed to any form of health risk just because it’s in the building.  You will not get sick looking at mould on a ceiling or wall.

Inhalation - when they are disturbed, you may be exposed to their spores when they are released into the air. Disturbing the fungus can send millions or even billions of the spores into the air causing health risks to individuals and pets within enclosed environments.

Absorption into the skin - If you directly handle materials that are mouldy, you can be exposed to the fungus and its spores through contact with your skin.

Ingestion - Eating foods that are mouldy or having hand-to-mouth contact after coming into contact with contaminated food.

Did you know that 250,000 spores can fit on a pinhead, and over a billion on a quarter?

 

How is The Fungus Disturbed?

Spores will become airborne by a simple action as cleaning. Other methods include:

  • Scrubbing or scraping of contaminated surfaces
  • Tear out or demolition of contaminated construction materials
  • Running an air conditioner or furnace with the fungus already in the ductwork
  • Vacuuming carpets that are mouldy (regular vacuum cleaner bags will blow the spores through the bag into the air and contaminate the room)
  • Running fans in rooms that have contaminated materials
  • Opening windows and doors when the house has a mouldy smell. The spores can be stirred up baby a strong gust of wind that blows into the house through the open window and door.

Known Reactions to The Fungus

Individuals have different sensitivity to spores that are airborne and will also react differently. Children, the elderly, those with compromised immune systems and respiratory problems (example asthma) are the most vulnerable. Healthy people may also have adverse reactions to high concentrations. The reaction may include:

  • Sinus/nasal congestion
  • Asthma
  • Tiredness/Fatigue
  • Sore throat
  • Blurred vision
  • Skin rashes
  • Eye irritations
  • Coughing
  • Tremors
  • Shortness of breath
  • Nose bleeds

The sad truth is that the majority of buildings in Greater London provide the ideal breeding environment to support mould colonies. For reproduction, colonizing, and growth, the spores require: 

  • A dark place
  • Dampness
  • Food source as an organic porous material
  • The correct high temperature

Sources of indoor moisture in London homes: 

  • Flooding
  • Roofs that are leaking
  • Damp crawls spaces
  • Basements that are damp
  • Steam from cooking. Try to cover pots and pans
  • Constant plumbing leaks
  • House plants
  • Shower/bath steam
  • Shower/bath leaks
  • Wet clothes on indoor surfaces. Try to dry clothes on the outside when possible
  • Clothes dryers that are vented indoors
  • Humidifiers
  • Stoves that are not exhausted outside 

Other conditions that help trigger growth are: 

  • 50% or greater humidity range.
  • Air that is not circulating.
  • Airtight construction.
  • Areas that are already infested.
  • Improper/inadequate ventilation.
  • Low nitrogen levels in the ground/air.

Rising Damp and Professional Mould Removal London

Rising Damp in Greater London

Rising damp is one of the most controversial and talked about types of damp. This is a relatively rare form of damp that is known to affect the walls of a building. It occurs by capillary action. Capillary action is when moisture from the ground travels up the building through the walls. This can also lead to wet rot of the timber.

Rising damp is first noticed by the damage it causes to the internal walls of a building. Plaster and paint can deteriorate and may cause wallpaper to loosen. Rising damp usually causes a stain that can be seen that often appears on walls resembling a tide mark. Sometimes the internal surface may have evidence of salt.

Causes of Rising Damp in London

Most buildings in London have a damp proof course (DPC) installed. This is a barrier that is installed to prevent water from rising up on the building. These are usually made from water-resistant and made of non-absorbant materials such as plastic, bitumen, slate. The material that is used is also dependent on the period in which the property was constructed.  DPC is also known to sometimes fail over time and may not have been installed on some older houses. If the DPC ha failed then your building is at risk of water travelling up your wall.

Sometimes the damp proof course can remain intact, but it may be bridged. When it is bridged the damp from the ground will be able to travel up past the damp proof course onto the building.

Examples of this include: 

  • Debris in the subfloor void or wall cavity.
  • External or internal plasters/renders overlapping the damp proof course.
  • External ground levels that have now been raised above the damp proof course.
  • Cavities that have inappropriate insulation materials.
  • Solid floors.
  • Intersecting abutting garden walls
  • Intersecting masonry structures.
  • Ground levels that are high. 

Damp or mould

Condensation is usually the cause of damp. Air, which always has moisture, will hold more moisture the warmer it becomes. The warmer it becomes then the more moisture it is capable of holding. If the air is allowed to get cool, for example, when it hits a cold surface (window/wall), then it cannot hold all the moisture in and small droplets of water will appear. The fungus will begin to grow if this water is allowed to soak in.

Structural Drying

Moisture can get deep down inside the building, collecting in places that cannot be seen with the naked eye or even compromising the building structure! We don’t stop our London mould remediation process with the fungus that you can only see.

London Mould Inspection

Our testing and inspection methods are designed to help our clients to understand their mould related issues through professional analysis, testing and investigation methods using proven international sampling strategies.

Decontamination

One of our highest priorities is the decontamination process. Depending on the level of contamination we will seal off the rest of the property to protect it from cross-contamination.   

Is Rising Damp in Greater London a Myth?

Whether rising damp exists or not has been a longstanding debate that needs to be addressed. The misdiagnosis of rising damp is the main reason for this debate.

There are underqualified and inexperienced tradesmen and surveyors out there that incorrectly diagnose rising damp. The treatment will fail and the damp issue will remain if the diagnosis is incorrect.

Misdiagnosis of Rising Damp in London U.K. 

Majority of the time rising damp is often confused with damp that is caused by condensation - this is one of the main reasons for misdiagnosis. One of the most reliable methods that may be used to tell the difference between dampness due to rising damp and dampness due to condensation is to compare the moisture from samples of mortar (you can use masonry), from the inner surface of the wall to the depth of the wall. If a sample taken from within the wall is not damp then the issue is considered to be surface condensation. 

In another example, the contractor did a correct diagnosis of rising damp but fails to treat it. In the majority of the cases, the contractor failed to successfully inject a chemical damp proof course cream. In both of these examples, there will be an angry and dissatisfied customer, and our industry suffers.

Penetrating Damp

This is caused by water leaking through the walls. This is usually caused by structural problems, such as faulty roofs or guttering, or cracks in the external walls.

Causes of Penetrating Damp in London

  1. Walls that are leaking

The first sign of penetrating damp is usually leaking or wet walls. Be on the lookout for damp patches, a discolouration of interior walls, mould, damp patches, water droplets, blistered plaster, and surfaces that are wet as these are all signs of penetrating damp. 

  1. Air gaps

Gaps in window frames and doors can also be a cause of penetrating damp. 

  1. Burst pipes and gutters

Water leaking from downpipes and gutters on the outside of your property can also be a source for penetrating damp.

Greater London Mould Removal and Remediation FAQ 

How Do I Know if I Have a Mould Problem in London?

You may have seen small black dots/specks, fuzzy-looking bluish-greenish clusters, white thread-like growths on surfaces in your house. Sometimes you may smell a musty odour. If you see smell or see the fungi indoors, then more than likely you have a problem. You cannot always rely on your senses to tell if you have a problem as hidden mould can be growing inside the ceiling cavities, floors, walls, long before being detected. 

Remember that all indoor fungus growth is usually caused by some form of water intrusion. Sources of water intrusion are flooding, toilet or bathtub overflowing,  leaking roof, leaking hot water tank, a leaking slab, a plumbing leak, water pooling next or under your house.
