Most Great Falls homeowners arrive at crawl Space Wood and Subfloor Repair having noticed something else first: a smell, a soft patch in the floor, or insulation on the ground. The inspection decides whether this is the right stage to start at.
The floor feels soft, bouncy or sloped, because the structure under it has been wet too long.
Wood and subfloor repair on piedmont and upstate ground
Around Great Falls the damage tends to arrive in steps, a little with each storm. Rim and band joist go first, because they sit at the top of the foundation where water running down the wall collects.
Around Great Falls the damage tends to accumulate in steps, a little with each storm, rather than arriving all at once. By the time it is noticed upstairs it has usually been building for a while.

Wood and subfloor repair in Great Falls: common questions
Why does the rim joist go first in Great Falls homes?
Because of where it sits. It runs around the top of the foundation, where moisture from the wall and poor exterior drainage concentrate, and it is usually covered by insulation that holds that moisture against it.
Can a rotted joist be repaired rather than replaced?
Both are used. Where a member has lost some strength but is sound where it bears, sistering alongside it is appropriate. Where the end has decayed at the bearing, that section is replaced. The inspection decides.
Why does my Great Falls crawl space stay wet for days after the rain stops?
Piedmont clay. Around Great Falls, at roughly 466 feet, the ground holds water against the foundation long after the surface looks dry.
Can I stay in the house while the work is done?
In almost all cases, yes. The work happens under the floor, and access is usually through an exterior hatch. We will tell you up front if anything about your Great Falls property changes that.
How do I know whether it is groundwater or a leak?
That is the first thing we establish on a Great Falls call, because everything after it depends on the answer. A supply line, a drain, water rising through the soil and runoff coming in through the vents each leave different evidence.
Can a rotted joist be repaired, or does it need replacing?
Both are used. Where a member has lost some capacity but is sound at its bearings, sistering new timber alongside it is often appropriate. Where the end has decayed where it bears, or the loss is extensive, that section needs replacing. The inspection decides, not a preference.
