When looking at the cavity walls, they drilled holes that they did not close. For this I called and they would contact me asap to close the gaps. But I never heard of it again. Furthermore, the total number of m2 insulated in the Netherlands in the quotation came to 103, with all other suppliers arriving at 90 m2, probably to drive up the price. The total cost for cavity wall insulation came to 3127 in their quotation, but we had it done by another company for 2000 to our full satisfaction. So you are a thief of your own wallet when you do business with Nederland Isoleert.
