Mold Testing in Shoreline, WA

Why Mold Concerns Are Common in

Shoreline Properties

Located just north of Seattle, Shoreline experiences extended seasonal rainfall and elevated humidity typical of the Puget Sound region.

Common contributing factors include:

 Mid-Century Housing Stock

Many Shoreline homes were built between the 1950s and 1980s and may have:

• Aging roofing systems
• Limited attic ventilation
• Outdated crawlspace designs
• Historic plumbing leaks

 Basement & Daylight Basement Moisture

Daylight basements are common in hillside areas. These can experience:

• Foundation seepage
• Poor drainage
• Condensation buildup
• Inadequate airflow

 Crawlspace Humidity

Elevated crawlspace moisture is one of the most frequent mold contributors in North King County homes.

 Remodeling & Construction Moisture

Shoreline has seen significant remodeling and infill development. Improper dry-out during construction can contribute to hidden mold conditions.
