It seems logical enough: if the crawl space feels damp, give it more air. Plenty of homeowners have spent years opening foundation vents when the weather warms up because that’s what they’ve always been told to do. The problem is that an open vent can only bring in whatever air is outside, and on a humid Alpharetta summer afternoon, that air may already be carrying plenty of moisture.<\/span><\/p>\n That’s why Crawl Space Ventilation involves more than counting vents around the foundation. Crawl Space Ninja looks at humidity, airflow, existing vents, and conditions underneath the house to see whether the current setup is actually helping the crawl space stay dry. Contact us online<\/a> to schedule an inspection.<\/span><\/p>\n An Alpharetta homeowner can open the crawl space vents on a pleasant spring morning and leave them that way as North Georgia moves into warmer, more humid weather. The openings around the foundation haven’t changed, but the air moving through them certainly has. What seemed reasonable in April may behave very differently underneath the house by July.<\/span><\/p>\n That seasonal change matters across Alpharetta, whether we’re underneath an established home closer to Downtown and Canton Street or a property farther toward North Point and GA-400. The neighborhood doesn’t tell us whether ventilation is working. Once we crawl underneath, we’re looking at how much moisture is in the air, how well it moves through the space, and what the materials under the house are showing us.<\/span><\/p>\n \nThe Vents Stay the Same. Alpharetta’s Air Doesn’t.<\/span><\/h2>\n
