Crawl space repair options
Pier and beam homes have a crawl space under the floor. Most repairs happen there, and the options range from small adjustments to larger structural work.
Common repair options
| Option | What it addresses | Often paired with |
|---|---|---|
| Re-shimming | Gaps between piers and beams that let floors dip | Leveling the floor |
| Adding or replacing piers | Piers that have settled, cracked or are spaced too far apart | Beam support |
| Beam, sill or joist repair | Wood that has sagged, cracked or rotted | Moisture control |
| Moisture control and ventilation | Damp crawl spaces that lead to rot, mold or pests | Drainage work |
| Drainage | Water pooling near or under the house | Gutters and grading |
Signs the crawl space needs attention
- Floors that dip, bounce or slope
- Doors that stick
- Musty smells or damp air indoors
- Standing water or wet soil under the house
- Visible rot or insect damage on beams
What to ask
Ask the company to photograph what they find under the house, list each item in the quote and say what is excluded. Moisture work and wood repair are sometimes separate line items. Have a qualified pro inspect the crawl space before you agree to a scope.

Common questions
Is it safe to go into my own crawl space?
Crawl spaces can have pests, sharp debris, wiring and poor air. If you are not comfortable, leave it to a qualified pro.
Will re-shimming fix my floors for good?
It depends on why the shims loosened. If moisture or settling piers caused it, those need attention too. Ask what caused the gap.
