The scary part? <strong>Most homeowners don\u2019t even know it\u2019s there<\/strong> until the damage is extensive.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"why-mold-in-your-attic-happens-so-often-in-sammamish\"><strong>Why Mold in Your Attic Happens So Often in Sammamish<\/strong><\/h3>\n\n\n\n<p>The #1 reason attics in Sammamish grow mold is <strong>poor ventilation<\/strong>. When warm, moist air rises from your home and gets trapped in an unventilated attic, condensation builds on cold surfaces\u2014especially wood and insulation.<\/p>\n\n\n\n<p>Once moisture settles in, spores find a home. And that\u2019s all mold needs to flourish.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"combine-that-with\">Combine that with:<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Roof leaks from heavy rainfall<\/strong><\/li>\n\n\n\n<li><strong>Poorly installed insulation<\/strong><\/li>\n\n\n\n<li><strong>Blocked soffit or ridge vents<\/strong><\/li>\n\n\n\n<li><strong>Bathroom fans venting into the attic (not outside)<\/strong><\/li>\n<\/ul>\n\n\n\n<p>\u2026and you have a recipe for one of the most destructive home issues in the Pacific Northwest: mold in your attic.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"the-warning-signs-of-mold-in-your-attic\"><strong>The Warning Signs of Mold in Your Attic<\/strong><\/h3>\n\n\n\n<p>Knowing what to look for is key.
