So when I got to this house RH inside was 70% outside 80%... A-framed house sitting on a poured concrete basement... septic had not been pumped in 8 years, sits on top of a hill with marsh 250' away to the right and a running stream 400' behind the house (where's this humidity coming from?). Windows were replaced this past spring (tightening up the house), used our Flir and you can still see some infiltration around window frames (they didn't replace the sills and did not install foam around the edges). Interior walls in the house are dry and all exterior walls and basement walls/floor read damp... oh yea... they had a French drain installed on the interior perimeter of the basement 9 years ago.
So my thoughts... they are pulling water into their home foundation, into the French drain. We had the sewer pumped out and applied a water chasing sealant to the basement floor and walls, the sill plate had previously been sealed with spray foam insulation.
Added dehu's and were able to maintain the house at 40%RH. Advised they have an air exchanger installed.
We have pulled our equipment and RH went back up to 70%, outside is now 60% and 32 degrees.
Other issues in this home... odor in closet, other side of closet is bathroom tub, surround is wood planks. Mold odors in home, tested... yep it's hot, 600-8000% high spore counts. Get behind closet, it was not the obvious wooden tub surround... it was mice infestation in the crawl spaces + wet fiberglass insulation from roof leaking because there was never ice dam blocker installed under roofing shingles (ugh!).
So now the insulation was removed, mold and mice remediated, insulation HAS NOT been put back yet (further tightening house!), recommended air exchanger HAS NOT been installed, my equipment pulled and humidity is spiking.. where is the moisture intrusion coming from? am I missing something?
