Mold All Over Staircase Walls in Lakewood, NJ

This homeowner in Lakewood, NJ, had some paintings and pictures that were hung along the walls of the staircase leading into the basement. He had taken them down in order to clean them, and when doing so, had an unpleasant surprise — there was mold hiding behind them. Paintings and pictures that are flush against walls can sometimes develop mold if the walls are damp in any way. 

With this home, the staircase area had the perfect environment for mold growth because humid unconditioned air from the basement came into contact with conditioned air from the first floor. You could feel the dampness in the walls from the condensation. We treated the mold in the staircase with an EPA-registered antimicrobial called MAPS 1 that attacks the mold at its DNA and kills it immediately. 

We then followed up with our patented, moisture-sensitive sealant called MAPS 2. This product encapsulates the surface mold is growing on and renders the mold non-allergenic and harmless and prevents any future mold growth in the treated areas. 

The homeowner did not want to risk future mold growth in the staircase area or basement of his home. The only long-term solution is to keep down the relative indoor humidity level in the basement (below 55%), so mold cannot grow. We installed a commercial-grade high-performance SaniDry Sedona dehumidifier and filtration system that is specifically designed to work in basements and crawl spaces. These dehumidifiers operate automatically with a built-in humidity sensor (humidistat) that allows the homeowner to set the target humidity level and let the machine take care of everything else. Also, these humidifiers drain directly either outdoors or to a sump pump, so there is no pan or reservoir to empty.
