Quick Answer
Cob homes, like any other earthship or natural building, require regular inspections to ensure structural integrity and prevent potential hazards.
Structural Integrity Checks
Regular inspections of cob homes are crucial to detect any signs of deterioration or damage. Every 2-5 years, inspect the exterior and interior of the home for cracks, gaps, or water damage. Check the cob’s moisture levels, typically by inserting a 1-foot long, 1/4 inch diameter probe into the wall about 12 inches from the floor. If the probe feels damp or wet, it may indicate high humidity levels, which can lead to erosion and weakening of the cob.
Pest and Rodent Control
Cob homes are at risk of pest and rodent infestations, which can compromise the structural integrity and safety of the dwelling. Inspect for signs of rodents, such as gnaw marks, droppings, or nests. Use natural deterrents like diatomaceous earth or peppermint oil to keep pests away. Seal any holes or gaps larger than 1/4 inch to prevent rodents from entering the home.
Maintenance and Repairs
Regular inspections also help identify areas that require maintenance or repairs. Check for signs of erosion, such as crumbling or disintegration of the cob, and address them promptly. Apply a natural sealant like lime plaster or clay-based coating to protect the cob from the elements. Consider hiring a professional natural builder or cob expert for complex repairs or structural assessments.
