Storm & Flood Damage Recovery in Lowell, MA

The canals are the likely reason. Those channels run several miles through the city and hold water at managed levels, which keeps the groundwater around them high regardless of the weather. A property well back from the Merrimack can still sit close to a canal reach. It explains cellars that are damp in dry spells and never really dry out, which is a different problem from a storm event and needs a drain and sump rather than better grading.

Expect the damage to be found below rather than where it started. Plumbing, wall cavities, and floor framing all run vertically through these buildings, so water from the top floor reaches the first floor and the cellar quickly, often before anyone on the top floor notices. Drying has to cover every level it passed through, which means arranging access to all three units at once. That coordination is usually the slow part, not the equipment.

Considerably longer than a wood-framed house, and the difference is worth planning around. Solid masonry absorbs a large volume of water and releases it slowly, so plaster and framing can hit their targets while the brick behind is still wet and re-wetting them. Ask for readings taken in the masonry itself, and treat an equipment removal date set from framing readings alone as premature.
