Joist repair, encapsulation, and moisture control that restore a firm, dry crawl space and stop the problem at its source — not just the symptoms.
Crawl Space Repair
Crawlspace issues almost always start with one of three things — moisture, mold, or failing supports. Match your symptom below.
A musty smell or visible mold growth, usually caused by excess humidity under the house.
Soft, crumbling joists or beams in the crawlspace from long-term moisture exposure.
Floors above the crawlspace feel springy or uneven — a sign the support posts or joists are failing.
Water pooling under the house or persistent dampness in the crawlspace soil.
Know What to Look For
These symptoms point directly to crawl space issues that get worse — and more expensive — if ignored.
When the crawlspace settles, walls and floors pull apart, opening gaps along baseboards. We stabilize the structure below so the interior stops shifting and gaps close up.
Sagging floors usually mean failing joists or support posts in the crawlspace. We install adjustable support jacks and repair joists to restore a solid, level floor.
Sticking doors signal that the house is shifting unevenly on its foundation. We re-level and stabilize the structure so doors and windows operate smoothly again.
A musty crawlspace odor points to mold growth from excess humidity or standing water. We eliminate moisture, remove mold, and seal the space to keep it dry.
Moisture in the crawlspace leads to rot, mold, and structural damage. We install drainage, vapor barriers, and dehumidifiers to keep the space permanently dry.
