A porch supply line splits on the thaw in a three-decker
- What homeowners notice
- After a hard cold snap, the third-floor tenant of a wooden three-decker hears water running inside the wall of an enclosed back porch. The supply line there froze days earlier and leaked nothing while the ice held; once the water moves again it comes out of the split and runs down through the porch floor into the two apartments below.
- What we do
- The building main is closed first, then the crew extracts standing water on all three levels and reads the plaster, lath and plank subfloors with meters and a thermal camera. The balloon-frame cavity is opened where readings stay high, soaked insulation comes out, and air movers and dehumidifiers are set floor by floor so the three households can stay put. A licensed plumber repairs the line on a separate visit.
- What to expect
- The ceilings and framing reach their dry readings over several days of checks, every unit's log and photographs go to the owner for the insurer, and plaster and paint are quoted once the cavities test dry.
