What problems could arise inside of a building that a house owner wouldn't know about it?

Structural Issues: Hidden structural problems, such as foundation settling, inadequate support beams, or compromised load-bearing walls, can weaken a building's integrity over time.

Electrical Wiring: Faulty or outdated electrical wiring may not be visible but can pose fire hazards or result in power outages if not addressed.

 Plumbing Problems: Leaks or issues within pipes hidden behind walls can lead to water damage, mold growth, and decreased water pressure.

Insulation Problems: Inadequate insulation or insulation gaps can lead to energy inefficiency, temperature variations, and higher utility bills.

Roofing Issues: Damaged or improperly installed roofing materials may cause leaks, water damage, and compromised insulation.

HVAC System: An inefficient or poorly maintained heating, ventilation, and air conditioning system can result in uneven heating/cooling, decreased indoor air quality, and increased energy costs.

Pest Infestations: Undetected pest infestations, such as termites or rodents, can cause structural damage and health hazards.

Mold and Mildew: Moisture buildup within walls or crawl spaces can promote mold and mildew growth, which can lead to health issues and property damage.

 Fire Safety: Outdated or malfunctioning smoke detectors, fire extinguishers, or sprinkler systems can jeopardize occupants' safety.

Radon Gas: Elevated levels of radon, a radioactive gas, can seep into homes through the ground, posing health risks if left unaddressed.

 Asbestos: Older homes may contain asbestos materials, which, if disturbed, can release harmful fibers into the air.

 Accessibility and Code Compliance: Non-compliance with building codes or accessibility standards can lead to safety hazards and legal issues.
