This is a common issue here due to our foggy climate. Trapped moisture can lead to mold and rot. We perform a thorough assessment and install proper moisture control and ventilation systems. This often involves repairing or installing ridge vents, soffit vents, and attic fans to create a continuous airflow, protecting your roof structure and improving indoor air quality.

Skylight leaks in SF are frequently caused by failed seals or improper flashing installation, which can deteriorate over time. Our repair process involves removing the old, compromised materials, installing a new, watertight flashing system specifically designed for our weather, and applying high-grade sealants. For a permanent solution, we can also expertly replace the entire skylight unit.

San Francisco's soil and moisture can compromise foundation walls, leading to cracks and water intrusion. Our foundation waterproofing installation creates a permanent barrier. We excavate to apply membrane systems and install drainage like French drains to channel water away from your home's base. This prevents structural damage, basement leaks, and the mold growth common in our local environment, safeguarding your home's value.
