We were worried about mold as we had some leakage from upstairs showers. During the initial inspection, it was determined that the leaks were temporary (we had resealed drain gaskets), and there was no issue from the showers. However, the crawl space did show lots of evidence of mold. The suggested remedy for our air quality issues was to seal the crawlspace and especially seal up the wall that bordered the living space wall of the house (split level ranch). The intake ducts for the HVAC were completely unsealed and were drawing in air from the crawlspace. There was mold present all over this area. The estimate for was a solid day of work. The crew was there early. Some focused on cleaning the ducts while others worked on sealing the crawlspace. Everything was done exactly as planned.
