This unique environment requires homes to be properly vented to prevent damage from moisture and mold.
1) Crawl Space: open the foundation vents in the spring and replace the crawl space door with a screened door (Richardson’s Screen on 39th and Ocean Drive will make one to fit). Remove any debris in the crawl- especially wood products. Left over decking is “lunch” for termites. Unless your ground regularly floods, a vapor barrier is recommended (basically, a thick plastic cover for the dirt). Close the vents/ crawl door in the fall to protect exposed water pipes during the cold months.
2) Attic: The soffit vents (around the perimeter of the house) need to be clear of insulation. Newer homes have ridge vents to help with air flow.
3) Drainage: Most newer homes do not have gutters. This drives the home inspectors crazy! Make sure water does not flow toward the house (and into the crawl space) after a heavy rain. Also check the water flow from the outside shower- proper grading will help. Trim landscaping away from foundation vents. And remember the old landscaping design with raised beds and railroad ties? This is a termite and moisture combination that will ultimately cause major problems.
