Mould and Condensation and How to Manage It After Cavity Wall Insulation Removal

If your defective Cavity Wall Insulation has been removed, you may want to consider the following steps in order to prevent further condensation and potential mould growth inside your home.

Ventilation is very important at providing a healthy environment, even more so in bungalows as there is no first floor for air to circulate. Defective Cavity Wall Insulation may not always be the sole cause of condensation and mould growth however, can often be a contributor due to restricted ventilation. We would therefore suggest adopting the following measures:

  • Installing a good quality extractor fan in the kitchen and bathroom areas
  • Double glazed windows fitted with trickle vents to allow for ventilation
  • Help to ventilate the property by opening windows, particularly after baths and showers to allow water vapour to escape. Dry clothing outside when possible.
  • Clean away old mould with specialized detergents following the cavity wall insulation extraction

Essentially, mould growth will occur when warm damp air settles on ‘cold spots’ in the walls. Defective cavity wall insulation is a principle cause of ‘cold spots’ so removing this should certainly help. However, if excessive water vapour is being produced and the property is not ventilated properly, then condensation and mould growth can still occur, which is why it is important to adopt the steps mentioned above and promote a clean healthy environment.

If you’ve got issues of any other nature with your Cavity Wall Insulation that may be down to the installer not following proper guidelines as to the install. It is now apparent that hundreds of thousands of home owners across the UK will need remedial work that will consist of a full extraction of the Cavity Wall Insulation and could well mean a whole host of other repairs and replacements directly caused by the install.

Your home and your health can be seriously affected if you do not take action.

Mark Group and Climate Energy Enter Administration on The Same Day

Two of the largest and most established energy efficiency businesses announced that they have gone into administration. The Mark Group and Climate Energy would appear to be casualties of the recent cutbacks in ECO funding and the folding of the Green Deal Finance Company. Naturally our first thoughts are for the employees who are looking for new job opportunities and their families that will of course be the hardest hit by this. Secondly of course is the supply chain that sits behind them and all the customers who have booked work with either of these companies.

 

That leaves tens of thousands of home owners who have had CWI installed by one of these firms no direct recourse and the only cover available for when things go wrong is directly with CIGA.

 

Your CIGA guarantee may be effective in most circumstances and you should check your guarantee as soon as possible, and ensure it is kept safe.

Flood and Fire Damaged Cavity Wall Insulation

We really feel for any household that has had to endure a fire or flood. Amongst a massive list of remedial work that is typically required after an event like this, Cavity Wall Insulation should be something that is assessed to determine the level of damage and action required.

 

The obvious issues with flood water is moisture saturating the cavity wall insulation, and penetrating the inner leaf of brickwork. Over a prolonged period of time the moisture is likely to transfer to the internal plaster and plasterboard, could become damp and mould growth could occur if left untreated. This can spoil décor, produce an unpleasant odour and in severe cases, particularly to those with any health issues. In these cases, it is absolutely essential the insulation would need to be removed.

 

Flood water often contains dirty untreated river water, diluted drainage and sewer water. These hazards can become “trapped” within the cavity wall insulation and remain there until the insulation is removed.

 

Fire damage is slightly different in the sense that it is the heat that can affect some cavity wall insulation systems, rendering it ineffective or even melting it.

 

Another problem faced in the case of fire may be wet cavity wall insulation due to the volume and pressure of water used by the fire brigade. In these circumstances, the insulation will again need removing to prevent all of the problems that likely to appear in the future such as damp. Insulation rarely recovers from fires or floods.

 

Your CIGA guarantee isn’t effective in these circumstances and your home and buildings insurance should pay particular attention to address this issue, as if it is left without being treated, it could end up a lot more expensive for you and them in the future.

 

If you’ve got issues of any other nature with your Cavity Wall Insulation that may be down to the installer not following proper guidelines as to the install. It is now apparent that hundreds of thousands of home owners across the UK will need remedial work that will consist of a full extraction of the Cavity Wall Insulation and could well mean a whole host of other repairs and replacements directly caused by the install.

Condensation and Cavity Wall Insulation

Often when our surveyors are out surveying people’s homes for Cavity Wall Insulation removal, we are asked about condensation; what causes condensation, how to reduce it and what effect if any it can have on cavity wall insulation. So, we thought the following article might be of some use should you feel you are experiencing condensation problems in your home.

 

Day-to-day activities such as; cooking, bathing, washing clothes, heating and even breathing produce water vapour. The air can only hold a certain amount of water vapour before it becomes saturated, and condenses back into a liquid. This is what’s known as condensing, the product of which is condensation.

 

Prolonged exposure to condensation in a property can cause; unsightly staining and damage to décor, mould to grow and in severe cases structural defects.

 

Types of condensation

 

Cold bridging – This occurs when moisture heavy air comes into contact with a surface that has a temperature at or below its dew point. This causes the water vapour to condense back into a liquid form and condensation occurs. An example of this could be if rubble or whole bricks are left within cavity after building works or construction, and are touching both sides of the cavity.

 

Interstitial Condensation

 

This type of condensation occurs when moisture heavy air disperses within a vapour-permeable material such as cavity wall insulation. If this material is warm on one side (The side nearest your inside walls) and cold on the other side (The side nearest your external wall) the moisture vapour will condense and deposit its liquid state within the material. Wet cavity wall insulation can lead to damp and mould growth if left untreated.

The Problem

Interstitial condensation is perhaps the more insidious, as it is difficult to detect until significant damage has occurred to the building fabric.

Interstitial condensation occurs where warm, moisture-laden air from the interior diffuses into a vapour-permeable material such as fibrous insulation or a porous brick wall. This is most common in cavity walled structures where the cavity is filled with insulation. The air reaches its dew point within the cavity, depositing water in the insulation layer.

The result is the insulation material can become saturated, so it no longer functions as an effective insulation layer. Water droplets can also form within the cavity, leading to damage of structural elements: corrosion of metal wall ties or rotting timber frames. These may not be evident until significant deterioration has occurred.

When the dew point is reached in the outer brick wall, water will be deposited within the porous brick. In very cold weather, the resultant freeze/thaw action can cause spalling or cracking of the brick.

The Solution

One way to prevent the water vapour entering the wall and reaching the cold surface is to apply a vapour proof barrier on the internal wall underneath the plasterboard and decorative finishes. Cavity trays are also required to assist moisture evaporation.

Chartered Surveyor Reports to Confirm Cavity Wall Insulation Removal

The number of requests for Cavity Wall Insulation removal following surveys for mortgage purposes has greatly increased.

Building Surveyors are increasingly aware of the problems associated with cavity wall insulation that has been incorrectly installed, particularly in timber and steel framed properties. When this is identified in a survey during the conveyance process, the lender may well generally be advised not to lend on the property until the cavity wall insulation has been removed.

Very often, a Chartered Surveyor will be required to confirm that the cavity is now clear of insulation once the insulation has been removed.

To assist our customers in this predicament, we can provide a free no obligation Cavity Wall Insulation Inspection Surveyor who, fortunately, specialise in energy efficiency and renewables. The cost of their inspection and report is absorbed by us a company, and with a national coverage they are able to offer an extremely professional and unbiased report backed by a RICS qualified Chartered Surveyor.
