Crawlspace Water Damage Cleanup in Lehi, UT

Crawlspace Water Damage Cleanup: What Is Happening and Why It Matters

Crawlspaces hide water well. Under older homes near downtown Lehi and Main Street, under additions, and beside some partial basements, a dark, low space holds plumbing, ducts and floor insulation. A cracked supply line, a leaking drain or water from outside can sit there for weeks with nothing showing upstairs except a musty smell or a cold, damp floor. By the time anyone looks, insulation may have fallen, the vapor barrier is holding a pond and the floor joists are soaking up moisture.

What is at risk is the structure. Wet joists, rim boards and subfloor weaken and invite mold if they stay damp. Fiberglass batts between joists absorb water, sag and drop. Ducts in the crawlspace can fill or rust, spreading moisture and odor through the home. If the water came from a drain or sewer line, the space has category 3 contamination in the soil and on the framing. Damp air from below rises into the living space and keeps indoor humidity high.

A local restoration crew suits up for tight, dirty work. They pump or extract standing water, haul out wet insulation and damaged plastic, and remove debris. Framing and soil are cleaned and treated, then dehumidifiers and air movers dry the joists, rim boards and subfloor. Readings are taken until wood moisture is back to normal, and the crew can lay new vapor barrier once the space is dry.

Lehi winters bring hard freezes, and pipes in vented crawlspaces are among the first to freeze. Spring snowmelt and summer pressurized irrigation along the foundation can push water into the soil around crawlspace walls. Hard water also shortens the life of fittings and valves on the lines that run through these spaces.
