ᐅ Replacing Insulation After a Fire With Water Damage?

Hello everyone,

There was a fire in our new build. During that, a water pipe burst and flooded the entire house with about half a meter (1.6 feet) of water 😡
The water penetrated through the walls and even came out through the brick joints on the outside. Quite a disaster. Now the question is whether the insulation needs to be completely removed or if I can leave it in place and let it dry? Naturally, drying it would be cheaper, but I’m not sure how to go about it.
My house is a timber frame prefabricated house, and the external insulation is made of "water-repellent" Rockwool "Fixrock VS".

Hello Berthold,
I am more concerned about moisture penetration in the wooden components. Mineral wool does not absorb water; in fact, the water-repellent type should not cause any problems in this regard.
If there is still water or moisture within the wall assembly, which I assume, it is, as mentioned, dangerous for the wood structure.
Drying should definitely be carried out by a professional company, especially for warranty reasons.

Have you already spoken with the insurance company? Would opening the wall (to allow proper drying) be covered by the insurance benefits?

This is a nightmare for every homeowner. Renovation after severe water damage must be carried out by a professional company. The wall also needs to be opened up; otherwise, the entire effort is worthless.

This is also a sensitive topic and an expensive matter. I just hope the damage is covered by the insurance. The wall has to be opened up and then everything needs to dry out gradually. A professional company also has the appropriate equipment.

This is a complex procedure, and the first step is to check whether the insurance covers the damage. In the case of such a extensive water damage, it is advisable to replace all the insulation in the affected area. In my opinion, simply drying it out does little to help.

It is important that the wooden components have not been exposed to water. The wall needs to be opened up, and a professional company will start the drying process.
