Storm & Flood Damage Recovery in Malden, MA

Water moves down a stack faster than it spreads across a floor. In a triple-decker the plumbing, wall cavities, and floor framing all run vertically, so a break at the top is often noticed two floors below as a ceiling stain. Drying has to cover every level the water passed through rather than only the two where it is visible, and arranging access to all three units at once is usually the slow part rather than the equipment.

Because of what the ground is doing. In December the soil is cold and beginning to freeze, so infiltration falls close to zero and almost the whole rainfall becomes surface flow. The same inch in July soaks in and evaporates within a day. A wettest month that lands at the start of the freezing season is a real local feature, and it is why drainage problems here cluster in late autumn rather than spring.

It is held at a controlled level by a structure downstream, which keeps tidal water from pushing up into the city. The tradeoff is that the river cannot fall away to make room when heavy rain arrives, so the storm system discharging into it has less head than it would on a free-flowing river. That is a design decision with real benefits; it just means local drainage depends on capacity rather than on the river dropping.
