Structural Drying & Moisture Mapping in Portland, OR

Structural Drying That Reaches the Water Hiding in Your Walls & Floors

Pulling up standing water is the fast part. The water that soaked into framing, subfloors and wall cavities stays behind, and on its own it can take weeks to leave. During that time wood swells, insulation stops insulating and mold has everything it needs.


Carey Water Restoration of Oregon dries the structure, not only the surfaces, in homes and businesses across Portland, West Linn, Oregon City and nearby communities. Structural drying includes:


  • Baseline moisture readings at multiple points in floors, walls and ceilings
  • Air movers that push air across wet surfaces and into wall cavities
  • Dehumidifiers that pull water vapor out of the air so it doesn't soak back in
  • Daily moisture mapping to track which areas are drying and which need more attention
  • Removal of insulation and other materials that can't be dried
  • Start and finish readings documented for your insurance company


Structural drying follows water damage restoration, storm cleanup and fire restoration, and it has to be finished before any rebuilding starts.

MATERIALS WE DRY

How Structural Drying Works on Different Materials

Every material holds and releases water at its own pace, so the drying setup changes with what got wet.

Wall Cavities

Water wicks up drywall and collects along the bottom of the wall. Air is directed into the cavity, and baseboards are sometimes removed to give it a way in.

Hardwood Floors

Wood flooring dries slowly and can crack if it's forced too fast. Drying is kept steady to give cupped boards the best chance of flattening.

Subfloors & Crawl Spaces

Many older Portland homes sit over crawl spaces that trap moisture. Dehumidifiers run under the house, and wet insulation between the joists is pulled out.

Concrete Slabs

Concrete holds water for a long time after the surface looks dry. Readings need to confirm the slab is ready before new flooring goes down.

Signs That Water Is Still Trapped in the Structure

  • Floors that feel soft or spongy days after a leak
  • Baseboards that swell or separate from the wall
  • Hardwood boards that cup or crown
  • Drywall that bulges or crumbles near the floor
  • Doors that stick in their frames
  • A musty smell that gets stronger instead of fading

Common Questions

Questions About Structural Drying

  • Can I turn off structural drying equipment at night?

    It's best to leave it running. Turning off air movers and dehumidifiers lets humidity climb back up, which slows drying and can add days to the job.

  • How do you know when structural drying is finished?

    Readings from wet materials are compared with readings from the same materials in unaffected parts of the building. Drying is complete when the two match, and both sets of numbers are documented.

  • What happens if structural drying is skipped?

    Trapped moisture makes framing and subfloors swell and warp, which leads to uneven floors and cracked drywall. Mold can start within a day or two, often behind walls where nobody sees it until the smell shows up.
