The appliances behind most Cambridge leaks
Stacked washer and dryer units in upstairs closets, dishwashers added during kitchen renovations and refrigerator ice maker lines all live on the upper floors of Cambridge's two- and three-family buildings. When a rubber washer hose bursts or a dishwasher door seal fails, water runs under the cabinets and finds the gaps in the floor.
- Burst or cracked rubber washing machine hoses
- Dishwasher door seals, pumps and supply lines
- Refrigerator ice maker lines crushed behind the fridge
- Washer drain hoses that slip out of the standpipe
Drying under cabinets without tearing them out
Water under a kitchen or laundry floor is hidden, and it is where mold likes to start. The tech who does the walkthrough uses pinless meters and thermal imaging to find the edge of the wet area, then the drying team removes toe kicks and drills small holes in cabinet bases to push dry air underneath. Floor drying mats pull water out of hardwood. Cabinets usually stay unless they are particle board that swelled. The structural drying page covers the equipment.
Braided stainless washer hoses and an automatic leak shutoff valve cost little next to a ceiling repair in the unit below.
When it reaches the unit below
An appliance leak in a condo building is usually a two-unit job, handled like any ceiling leak. The photos and drying logs go to both owners and the association. The EPA WaterSense leak page has simple checks for appliance lines, and the EPA mold cleanup page explains why hidden wet areas under cabinets need drying, not just a towel.
