Do I Have to Replace Wet Insulation?

St Louis - St Charles Insulation Removal Company.

Replace Contaminated Insulation

Usually, yes. It depends on the extent of water damage but in most cases it’s imperative that you replace it so mold doesn’t grow.

Water affects different types of insulation in different ways. Take the two most common types of home insulation: cellulose loose-fill and fiberglass batts. Let’s go over how water impacts each one. And if you ever suspect contaminated insulation, no matter which type you have, you should call an insulation contractor in St Charles and St. Louis MO right away.

Cellulose Loose-Fill Insulation

Cellulose loose-fill insulation is comprised of loose, gray fibers. It’s a popular and eco-friendly option but it can soak up water like a sponge. If only a small section is wet, you may be able to leave it alone to dry out, or just replace that one section. It may take a couple of weeks to dry, but this is only an option if you have identified the source of the water and have addressed it.

If the leak is extensive and you can’t find the source, this type of insulation is a breeding ground for mold and mildew. Replacing the whole area is your best move at this point

Fiberglass Batts

Pink loose-fill or batting is a type of fiberglass insulation. It doesn’t absorb as much water due to its spun glass fibers. Water damage isn’t as grave a concern for fiberglass batting as it is for other types in terms of mold, but water can affect its functionality.

Due to the fiberglass’s density, it’s tough for water evaporation to occur. If you have drenched batting, then it’s wise to replace it all. If you don’t, the wood underneath can get saturated and then rot. Use a dehumidifier in the area to try and dry it out first but if this doesn’t work, call an insulation professional in St. Charles MO.

Can You Save the Insulation?

There are a few factors to consider when wondering if your insulation can be salvaged or not.

Insulation Type: Some types of insulation will dry out on their own with the use of fans and dehumidifiers. Can’t hurt to give it a shot.
Timeframe: If you don’t know when the leak occurred, you should replace the insulation where you see evidence of water damage because you have no idea how long the water has been sitting there. If you know the leak happened in the last 48 hours, you can try the above methods to dry it out before mold sets in.
Location: If you suspect the water damaged insulation is in the wall cavities, your only option for drying it is to open up the wall and inject dry air directly inside.

If your insulation is too wet and turns clumpy or you spot mold growing on it, these are signs you should call a contractor for replacement.
