Excessive caulking indicates chimney separation from the house.  

Decay at lower sections of exterior door indicates long term water penetration that could involve hidden areas of damage to surrounding components.

Gutters pulling away from the home can cause damage to the fascia, soffits and lead to direct water penetration at the foundation.

Overflow vents are often clogged/blocked and can lead to leaks that damage the cabinet and flooring.

Many people do not take time to look under the toilet tank where leaks can occur and do hidden damage to the subfloor/joists.

Insects (flies, ants, mosquitoes, etc.) can enter the home through torn screens when windows are left open.

Even in new construction microbial growths can start growing when moisture levels are consistently above 19%.

Wood destroying insect activity is noted in isolated areas.

Rusted drain pan is an indicator of improper drainage of condensate drain lines.

When nails back out, the roof covering is susceptible to water penetration which can damage underlying components. Hidden damage in attic often goes unnoticed until serious repairs are necessary.

Plumbing boots should be replaced every 8-10 years and are typical areas where leaks are detected.

The bottoms of corner trim boards often go unpainted/sealed even in new construction. Moisture is absorbed from the bottom of the trim board and premature decay will occur.

Rusting of the water heater exhaust vent indicates inadequate ventilation and can lead to deadly Carbon Monoxide levels.

Plumbing pipes with plastic polybutylene connections are prone to leak.

When there is more than 3 steps, handrails are required to prevent injury in the event of a fall.

Crawlspace moisture can saturate the insulation which causes is to hang low. This prevents insulation from working as intended.

Looking under sinks and in front of dishwashers is necessary to inspect for hidden damage. Moisture damage observed from under cabinet can lead to fungal growths and decay of surrounding components.

When gutters cannot drain properly, rain water can discharge directly at the foundation which can lead to water penetration and unsanitary conditions of the crawlspace. Direct drainage can also damage a slab foundation/footing.
