Groundwater & Basement Water Intrusion in Helena, MT

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.

No obligation: the assessment comes before any scope

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

Why does a small loss travel so far here?

Because the building has opened up. Indoor humidity in the heating season falls into single figures at this elevation, and timber shrinks at that, so joints at floors, around trim and at framing junctions are wider in February than they were in July.

Does that reverse in summer?

Mostly, and that is part of the difficulty. The timber takes moisture back and the joints close again, so a gap that carried water in January is not there to be found in June. The route disappears before anyone goes looking for it.

What does seasonal movement change about the search?

It means following the water rather than the openings. There is little point looking for the gap it used, because the gap is seasonal; the readings across the structure show where it went, and the assembly is opened on those rather than on anything visible.
