"Mel Darling inspected the foundation of our house and carefully explained the issues she found. She was very thorough, and very good at explaining the technical details of what it would take to stabilize the foundation. Because we are planning to sell the house, she worked with us to find options that would make sense for our situation. She was great to work with and very knowledgeable. I highly recommend the company, and especially Mel as a project manager."

Types of Crawl Space Damage in Seattle

Common Causes of your Crawl Space Problems in Seattle

Moisture and Humidity

Excess moisture in your crawl space can lead to mold growth, wood rot, and structural damage over time.

Groundwater Seepage

Poor drainage or leaking pipes can lead to standing water in your crawl space, potentially causing mold growth and compromising structural integrity.

Poor Ventilation

Open vents in your crawl space allow humid air to enter, leading to condensation, mold, and long-term moisture damage.

Pest Infestations

Damp or unsealed crawl spaces create an inviting environment for rodents, termites, and other pests, leading to structural damage and contamination.

Soil Settlement

Shifting soil beneath your home can lead to foundation settlement, causing sagging floors and damage to crawl space supports.

Foundation Cracks

Cracks in crawl space foundation walls allow water, pests, and unconditioned air to enter, causing moisture and structural issues.

High Energy Bills

Poorly sealed or damaged crawl spaces can increase heating and cooling costs due to energy loss.

Stack Effect

Damage in your crawl space allows mold and odors to spread into your home. Repairing the crawl space prevents this, improving your air quality and living environment.

Climate Conditions

Heavy rains or drought can shift the soil beneath your home, leading to sagging floors or structural damage in your crawl space. Repairing these issues restores stability and protects your home from further problems.
