1. Make sure the structure is sound.
Check to see if any renovations have damaged the structure. Look for termite damage. Ensure that "settling" hasn’t caused damage to the foundation or support beams and joists.
2. Check if electrical and wiring systems are safe.
Loose wires or incorrectly installed or wired receptacles, switches or electrical box problems are hazardous and should be fixed. All homes should have a minimum of 100 amp service.
3. Look for leaks.
Water can leak into unexpected places, causing extensive damage over time. Examine the underside of sinks and dishwashers, along ceilings, on floors or along basement walls. Plumbing fixtures, water-using appliances, drain pipes, water supply inlets and outlets, basements and roofs can all be causes and sources of water damage.
4. Resolve safety issues.
Make sure windows open easily and lock securely, and entrances/exits can be securely locked. Correct hazards such as hidden curbs, loose railings and stairs, uncapped wells, etc.
5. Check plumbing.
Faucets should run easily and shut off completely, bathtubs should be properly caulked and grouted, toilets should be bolted down securely, drains should be clog-free, and the water heater should be in good working order.
6. Make sure your heating and cooling systems work.
Make sure they are up to date, clean, in good working condition and have clean filters. Check refrigerant in air conditioning units.
7. Have a friend take a look.
A general, unbiased overview of your home by a neighbour or friend may reveal issues you might have overlooked.
