Why your neighbors trust Groundworks

We've earned 19 five star reviews.

"I contacted Groundworks because I know foundation issues are not something to sleep on. I wasn't sure if my home had any serious issue or just normal settling. Jim came out to my home, explained everything to me, showed me data, measurements and was patient, respectful and kind. Jim explained everything in a way that didn't make the process feel overwhelming. At the end of the meeting Jim told me there was nothing of concern and I from the beginning he felt like someone that was direct and won't sell me something I didn't need. I feel grateful Jim and his evaluation of my home"

Types of Crawl Space Damage in Sunnyvale

Common Causes of your Crawl Space Problems in Sunnyvale

Moisture and Humidity

Excessive moisture and humidity in your crawl space, often caused by poor ventilation or water seepage, can lead to mold growth, wood rot, and even structural damage.

Poor Drainage

If your home's drainage system isn't working effectively, water can pool around the foundation, raising moisture levels and allowing water to infiltrate the crawl space.

Open Crawl Space Vents

Open vents can bring in outside air and moisture, resulting in condensation, mold growth, pest infestations, and long-term damage to your crawl space.

Soil Conditions

Moisture-retaining soil under or around your home can raise humidity levels in your crawl space, potentially causing structural damage and fostering mold.

Leaking Pipes

A leaking pipe near or inside your crawl space can release excess water, creating conditions for wood rot, mold, and other structural issues.

Insulation Damage

Wet or missing insulation reduces energy efficiency and allows drafts to enter your home.

Stack Effect

Mold and mildew in your crawl space can cause odors that rise into your home. Encapsulation seals off the space, keeping your air fresh and healthy.
