Groundwater & Basement Water Intrusion in Boston, MA
Basement seepage, failed sumps and water through the slab are extracted and dried, and the path from the ground is found so the floor stays dry next season. The path from the ground is named first: through the wall, up through the slab, back through a drain, or from a sump that stopped. The space is extracted and dried, with the porous materials the water touched removed, and the delivery is addressed, because a dried floor only stays dry if the water stops arriving.

Often needed alongside
- Structural Drying & Dehumidification
Sealed air movers and dehumidifiers bring framing, subfloor and drywall back to a measured dry standard, with daily readings logged from inside the material.
- Emergency Water Extraction
Standing water is pumped and extracted around the clock, before it climbs the walls and soaks the subfloor. Same-day response where coverage allows.
- Mold Inspection & Testing
An independent assessor confirms whether the assembly that got wet is actually dry, whether growth started while it was not, and how far it reaches.
Frequently asked questions
The unit above leaked through the plaster ceiling. What is the drying job?
The joist space between the two units and the plaster on both sides of it. The contractor opens the ceiling under the wet area, removes any soaked insulation, dries the cavity with air and dehumidification, and reads the joists and the plaster until both hold the dry standard. The ceiling is patched after that, not before, or the stain returns.
How long does a fieldstone basement take to dry after a December storm?
Longer than a block basement. Fieldstone walls hold water in the mortar and the stone and release it slowly. Once the wet finishes are out, the contractor seals the basement, runs air along the wall base and a dehumidifier sized to the space, and reads the floor and wall daily. Two weeks is common in a wet December.
Can a triple-decker be dried in winter with the heat on?
Yes, and the heat helps. Winter indoor air in Boston is dry, so a sealed room with air movers and a dehumidifier reaches the readings in a few days once the line is repaired. The complication in a triple-decker is that a leak often involves two units, so there are more cavities to read rather than slower ones.
