Making good (or breaking bad!)

-
CIGA are particularly concerned about the appearance of a building that has had retrofit CWI installed.

From CIGA's documentation "Technician’s guide to best practice Version 2.0 - Issued July 2002"

The importance of making good after the installation is completed, cannot be over- emphasised. Leaving the property in the same condition that you found it is the best possible advertisement for the industry, and your best source of new business leads.
Rendered or Tyrolean-faced walls
Special care must be taken with rendered walls; the colour and texture of the render and the type of chip or pebble should be copied as closely as possible.
Colour matching can be carried out using paints or colour dyes, but remember to ask customers if they have any of the original paint Minimise the area you are painting to reduce the repair area.
A mortar based on white cement may be useful for filling holes in a white rendered wall. 

 It sounds like a lot of care an attention goes into finding the exact match to create as seamless finish as possible however  this artisanal care and attention was somewhat missing on the day CWI was installed in our house.

Poor match in material and cosmetic finish.

Poor bond and cracks. The poor match of material leads to different thermal expansion properties and cracks which could cause water ingress. Thank you CWI installer.

More poorly matched render - actually just a bit of porous looking cement
The building probably has  rough cast which has very different properties to a blob of modern cement.
They have not even tried to pain over the holes.

To add insult to injury the CIGA inspector drilled two holes, filled them will unspecified silicone product and left the brick dust on the floor for me to clean up.

CIGA inspector silicone plug. How long is this going to last?
From CIGA's own "Guide to Best Practice for Complaint Handling v7 Oct 2015"
Mortar/ making good.
 It very important to re-instate making good all areas of brickwork / external facings following investigations, it is recommended that making good of masonry should not be of a temporary measure

So I'm marking this is a failure to adhere by CIGA's best practice for both the installer and the CIGA inspector.

The controversy over Cavity Wall Insulation 'topups'

-
Image
In this article I talk about the practice and problems of topping up insulation when voids are discovered, why it is being done and the potential violations of building regulations. I can only put forwards what I have understood from public documents and personal correspondence  So I welcome corrections or clarifications from the industry on this important issue for home owners and will happily update this post to reflect any inaccurate statements. We know that 100s of topups are done every year.   From what I can gather : If the BBA have not approved these topups then the relevant local authority building control should have been notified prior to topping up as an 'off licence' use of the product.  It is not clear that the correct procedures are being followed in all cases. Background :Voids are common A void is simply an area cavity between the walls which is missing insulation.  If a void is large enough then the insulation will not be compliant with the meter square

Lintels, weep holes and render

-
Image
I found the notion of lintels in cavity trays difficult to visualise. The reason I'm looking into lintels is that there is a damp patch that runs along the lintel over the front door. Brick houses built today will have cavity trays and weep holes inserted into the design. You will spot weep holes these as either gaps in the mortar or where the mortar is replaced with a perforated plastic insert as below. CIGA state that no water should enter the cavity is properly maintained building. If that is so then why does building control mandate a cavity tray. Typical modern cavity tray with weep holes sitting on a steel lintel. The purpose of a cavity tray is to ensure moisture that gets in the cavity when driven through the mortar joints or other means is directed back to the outside wall and out of the building. If you didn't have a cavity tray or some sort of damp proof course then moisture would collect on the flat lintel and then flow off the sides of the lintel or soa

Discrepancies between Internal and external DPC (damp proof course)

-
Image
In a cavity wall construction, one would expect that the damp proof membrane to be at the same level on both walls. It turns out this is not always the case and my house is a good example where the internal wall's DPC is more than a brick lower than the external wall DPC. I didn't even think to check this before reading the CIGA Technical note 14 . This clearly states that if the distance between DPC and ground level is within a brick (as was the case with my property at time of install) then 'numerous other factors' must be assessed before declaring the dwelling as being suitable for CWI. CIGA  Technical note 14 . One of the factors is the relative level of the inner and outer leaf DPC. This is exactly what I found in my property. Ive used a floorboard to show the position of the internal floor. The DPC is clearly a brick below the floorboard and less than brick above the block paving. External leaf DPC is 1 brick below the floor level.
