1. Faulty wiring—Faulty wiring problems include such things as open junction boxes, amperage mismatches, or no wire nuts on wires. A very common electrical wiring problem inspectors should be looking out for is an outlet with reversed polarity. This is when the “hot” and “neutral” wires are placed on the incorrect terminals. Another common improper electrical wiring finding is when there are two electrical circuits/feeds attached to a single breaker; also known as a double tap. This can be considered a fire hazard, and a common correction to this problem is a twin breaker. Other solutions to these common problems include fixing the junction boxes and upgrading to at least 100 amps.
2. Poor grading and drainage—Signs of poor grading and drainage problems include spongy soil around the foundation and signs of leaking in the basement. Basement leakage more often than not stems from inadequate or eroded exterior grading. If this is found in your home, you should regrade so that all the ground slopes away from house for 10 feet and remove porous material around the foundation.
3. Faulty gutters—Inspections often find clogged or bent gutters, which can contribute to water not being channeled away from house. Regular maintenance and cleaning of your gutters as well as adequate gutter size can help cure some of these findings. Also, use splash pans to divert the gutter run-off.
4. Basement dampness—Basement water damage shows up in the forms of water stains, powdery residue on walls, and mold or mildew. After you have regraded and fixed the gutters to direct water away from house, you can apply waterproof coatings to basement and repair any water damage.
5. Roof problems—Inspectors look for brittle or curled shingles and broken or missing flashings. Apply new shingles to the roof or tear off if needed. Also replace flashings; especially around chimneys and other protrusions such as vents, skylights, etc.
6. Foundation flaws— Flaws include cracks in the foundation, sloping floors, and sticking doors or windows. Fill foundation cracks with silicon caulking or epoxy and apply waterproof coating to exterior. Also make sure all windows and doors are operable.
7. Poor upkeep—The upkeep of your home is included in the inspection. It may need repainting, have worn carpeting, or have a cracked driveway. A common finding relates to the fascia on the exterior of the house; this includes missing pieces, rotted pieces, or fascia boards with little to no ventilation. This can affect the lifespan of the roof. The best solution is to give your house a facelift.
8. Faulty plumbing—Plumbing problems include inadequate water pressure, slow drains, and signs of leaks on ceilings. Leaks in the plumbing underneath sinks and around toilets are two of the most coming findings. A galvanized water main can lead to poor water pressure due to corrosion of the inside of the pipe. Copper water main lines eliminate the water pressure issue. Make sure you clean and rout drains, reseat toilet with new wax ring, and repair leaks.
9. Poor ventilation—Ventilation problems are those such as extreme heat in the attic and vapor condensation. Sometimes when bathroom vent fans are installed, they are not properly vented to the exterior of the home. Instead they are vented into the attic or crawl space. The moisture from the bathroom can easily cause mold problems. Ensure that your roof soffits are not blocked, install additional roof vents, and make sure to vent bathroom and kitchen fans outside.
10. Defective heating—Defects are caused by cracks in the heat exchanger or water tank and carbon monoxide leaks. The heating systems in your home should be serviced annually to ensure everything is in proper order. If you do not get your system serviced annually, then a cleaning and inspection of the heating system is in order. Reseal your chimney flues and replace the sacrificial anode in your water heater.
