Avoiding Unwanted Guests in your Crawl Space

Look at the exterior entry into the crawl space.

  1. An exterior entry should have a full cover securely installed and sealed. This can help prevent animal, insect and moisture entry. The entrance should have adequate clearance from landscaping and installed appliances for easy access. Entrances that are below grade should have an adequately sized window well with a drain or cover installed to help prevent water pooling and infiltration. Look for water damage and deterioration on the framing and cover. Next walk around the exterior looking for the crawl space vents.

2. Vents should have covers installed. Covers usually consist of screens to help prevent animal and insect infiltration and a sliding grate to allow ventilation adjustments. The vents should be clean and not blocked off or covered unless proper interior conditions exist. The vents should have clearance from vegetation and not be below grade to allow proper air flow and help prevent water infiltration.

Damage and deterioration observed should be evaluated and repaired by a qualified and insured contractor. As you walk around the exterior look for gaps or cracks.

3. Gaps and cracks should be sealed to help prevent rodent, insect, and moisture infiltration. Next, look at the foundation for cracks and/or shifting. Cracks larger than 1/8” are considered structural and an evaluation by a properly accredited and insured structural engineer is recommended.
