The most important areas to stay on top of are anything related to water, drainage, moisture, and mechanical performance. That includes: keeping gutters, drains, and downspouts clear making sure exterior drainage paths remain functional monitoring caulking and sealants servicing heating and ventilation systems managing indoor humidity and condensation responding quickly to leaks, moisture, or signs of water intrusion Water-related issues can cause the most damage if left unaddressed, so it is important to pay attention to anything that could allow moisture into the home or interfere with proper drainage.
