Why your neighbors trust Groundworks

We've earned 482 five star reviews.

"I've had Matvey/Groundworks come out twice and they did not charge us for their time. First time was for something more aesthetic related to flooring and then we called them again for foundation/concrete assessment. Gardner was detail oriented, easy to communicate with, prompt and did not push any product in his presentation of scope/findings/solution. Big fan! Highly recommend."

Types of Crawl Space Damage in Mercer Island

Common Causes of your Crawl Space Problems in Mercer Island

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.
