[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]We have a finished basement that doesn’t smell or otherwise seem damp or musty. During the recent storm, we had an outside drain clog with debris and water came in, requiring fans to dry carpet and minor mold remediation under the baseboards (we didn’t realize the water had come in for several days).

In doing a broader inspection, the water remediation company found out that the insulation in the basement exterior wall was “soaked” and seems[b] this is unrelated to the water getting in from the clogged drain, rather likely due to water coming in through the wall directly.[/b]

The cost to fix the flooding damage wasn’t terrible, but wondering if anyone has had this wet insulation issue before and what the cost, time and process was to fix it was.

To the bolded, I don't see how he could possibly know this, unless he had a time machine and could travel back to before the drain clogged and checked the wall. The problem with remediation companies is they're always looking to create big jobs.

That said, if fiberglass insulation in a basement wall gets wet you need to remove the drywall and the insulation and let the framing dry. There's no way to dry the wall out otherwise. An inspection of the framing will tell you whether it has been chronically wet. If it's a chronic problem you have to figure out where the water gets in and stop it.

For this reason fiberglass insulation isn't really appropriate for basements. Insulation that is non-permeable, like foam board or closed cell spray foam, can better resist occasional wetting. [/quote]

Wrong, no insulation is designed to get wet without remediation and removal of the walls and materials to dry out. A basement should never get wet ever, the occasional allowance is incorrect information. You need to remediate with exterior water proofing, sump pumps and French drains, in fact all new houses built are required to do so.[/quote]

You can have someone dig around the base of the house (or at least where the water problems seem to be). Is it brick? If so, you can have the brick parged (applying concrete) below grade and then apply tar to the exterior. This is waterproofing. I'd check your downspouts and make sure you clean your gutters too.[/quote]
