Mold Removed From a Well Water Room in Stamford

A well water treatment room is a small, closed space full of equipment that handles water all day: softener and filter tanks, a brine tank, a pressure tank and the pipes between them. In this Stamford home that room had been doing it for years, and the walls showed it. The homeowner asked for help with mold growing in the room. At the assessment the growth ran along the floor line on every wall: dark spotting on the bottom of the painted drywall, heavier on the green foam board insulation behind the tanks, and across the floor and the wire shelving in the corner. The tanks themselves were spotted too.

Because the growth was concentrated low on the walls and the drywall and insulation behind it hold moisture, the scope was to remove the affected wall about 4 feet up, around the room, rather than wipe the face of it. On October 21 the crew protected the floors and sealed the room with 240 square feet of containment and a zip door. HEPA negative air scrubbers ran for three 24 hour periods, exhausting through 25 feet of lay-flat duct and a HEPA filter so the air leaving the work area was filtered.

Then 160 square feet of drywall and 160 square feet of insulation came out and were bagged inside the containment. The exposed studs and framing were HEPA vacuumed in detail, wet wiped and bio cleaned, and the same 160 square feet was fogged with a plant based antimicrobial through a cold ULV fogger to reach the gaps a wipe cannot. The rest of the room was HEPA vacuumed and bio cleaned, and the debris was hauled away. This job did not include testing, putting the walls back, or any work on the water treatment equipment itself. A room like this stays humid, so how it is ventilated before new drywall goes in is worth a conversation.
