Cavity wall insulation issues – Lack of information and possible defects?Make Text Bigger
Back in 2010, the freeholder of the housing estate where I own a ground floor flat undertook a large programme of works to install cavity wall insulation to nine 4-storey blocks of flats.
A few years ago I had to have an EPC carried out to enable me to let my flat. The EPC assessor assumed that there was no cavity wall insulation. I contacted him and provided the guarantee I received from the freeholder. I then asked to have the EPC updated accordingly. Unfortunately, I was told that the certificate wasn’t useful because it didn’t specify the kind of material used in the cavity nor the thickness of insulation.
The freeholder advised that they didn’t have the information (is that possible?) and I should contact the company that installed the insulation direct. Unfortunately, I found out that the company had gone into administration shortly after the installation was carried out, so I am unable to get the information required.
How am I able to obtain the necessary information to update the EPC?
Fairly recently (October 2020) we had heavy rainfall and the rain penetrated through the external walls into the flat. The internal walls, recently redecorated, were soaked wet and water was dripping from the ceiling around the windows.
The freeholder’s surveyor carried out a visual inspection, but couldn’t find any visible problem and considers it a one-off incident.
I believe this could be caused by failing cavity wall insulation (possibly incorrectly installed) which could also explain the problem my previous tenant was experiencing from 2015 when had complained of leaky windows. The surveyor from the company that had installed the windows at the time couldn’t find any leaks or fault with the windows, so we assumed there were problems with condensation which also explained the problem with mould growth on the walls around the windows.
I am not satisfied with the sole visual inspection carried out by the freeholder and I would like them to carry out a more intrusive inspection, but I am not having any response or the information I have requested regarding the cavity wall insulation, the details of the installation and the building insurance.
Has anyone had a similar experience and wondering what steps I could take to ensure the freeholder provides the required information and investigates the problem further?
