A professional home inspection is a visual examination of the condition of a property and is always conducted by a licensed professional inspector. The inspector will check a wide range of items, including (but not limited to) structural, electrical, plumbing, built-in appliances, heating & cooling systems, as well as the condition of the roof, attic, foundation, crawlspace, siding, and decks. The key reason to conduct a professional home inspection is to make an informed buying decision about the condition of the home.

Here are 11 of the most common items found during a professional home inspection:

1. Mold In Attic Or Crawlspace

Mold growth in attics and/or the crawlspace of homes is more common than you might think in our Pacific NW climate. It grows when high humidity and poor ventilation exist together. The presence of mold can cause health issues such as allergies and respiratory problems. Mold can also cause structural damage to the home which can lead to costly repairs. Remediation by a licensed contractor is relatively easy, but the key is to remove the source of mold growth by ensuring better ventilation and by repairing leaks or moisture damage promptly.

2. Detached Bathroom Fan Vents

This is when the vent pipe that carries moisture and humidity from the bathroom to the outside is disconnected or not properly connected. This can cause moisture to build up in the attic or crawlspace - leading to mold growth and structural damage to the home. Detached bathroom fan vents can also lead to poor indoor air quality and can create unpleasant odors in the bathroom. To prevent detached bathroom fan vents, it is important to ensure that the vent pipe is properly installed and connected to the fan and to regularly check for any signs of disconnection or damage.

Tip: Bathroom fans should always be used while showering or bathing and they should run for 30 minutes afterward too.

3. Lack Of Attic Vents

Without proper attic ventilation, heat can build up and cause damage to the roof and attic, as well as make the living space below uncomfortably warm. This can lead to poor air circulation, which can trap moisture and lead to mold growth. It can cause the attic temperature to rise significantly, which can cause shingles to become brittle and shorten their lifespan. Not having enough attic vents can also cause water to back up under the shingles and lead to leaks inside the house.

4. Clogged Gutters Or Downspouts

Clogged gutters and downspouts can cause water to overflow and potentially damage the exterior and foundation of a home. When clogged, they can no longer effectively channel rainwater away from the dwelling, which increases the risk of water infiltration to the crawlspace or basement. Clogs can also cause water to back up, which can result in damage to the roof and fascia board, as well as create an attractive breeding ground for mosquitoes and other pests. The clogs can be caused by a variety of factors, including leaves and debris, pests, and even ice during the winter months. Regular maintenance and cleaning are essential.

5. Moisture In The Crawlspace

Moisture in a crawlspace can lead to mold growth or structural issues. Standing water in a crawlspace can cause wood rot, which can weaken the structural integrity of a home. A 6 mil black plastic moisture barrier should be installed on every inch of the ground so that there is not any exposed earth. Proper ventilation is essential in preventing moisture buildup as it allows for air circulation and prevents trapped humidity. If water is present in a crawlspace, dehumidifiers, trenching around the foundation perimeter with perforated pipe and gravel, grading toward the low point drain and/or a sump pump can be used to remove it and prevent further damage. In our climate, there will always be some moisture present in a crawlspace, but it must have a way to get out. This requires regular checks under the house and regular maintenance but this area is often forgotten.

6. Over-Amped Breakers

This occurs when too much electrical current flows through the circuit, causing the breaker to trip and shut off the power. This can be due to having too many electrical devices which are running on the same circuit, or if there is a problem with the wiring in the circuit. Overheating, buzzing, or burning smell can all be signs of an over-amped circuit. Over-amped breakers can be dangerous and can cause damage to appliances & electronics or even start a fire, so it's important to identify and correct the problem as soon as possible.

7. Evidence Of Pests In Attic And Crawlspace

Droppings and excrement are clear indications of a pest infestation. Gnaw marks on wooden beams or electrical wiring can signal the presence of rodents. A musty or pungent odor may also indicate pests being in the home. Nesting materials, such as insulation that has been pulled away or chewed through can be evidence of pests living in the attic, walls, or crawlspace. This is considered a health issue and must be treated immediately. Make sure you regularly check for these signs and call an exterminator if you see any evidence of unwanted visitors.

8. HVAC Needs Service

The HVAC system needing service is noted on over 50% of inspection reports. Inspectors recommend HVAC service should be scheduled annually. Also, to preserve good air quality, the furnace filter should be changed regularly. An HVAC system that is in need of service can lead to decreased energy efficiency and higher utility bills. Signs that an HVAC system needs attention include strange noises, dirt, unusual odors, or a lack of hot or cold air. Annual maintenance and service can help to prolong the life of an HVAC system and prevent costly breakdowns.

9. Torn Or Uncovered Eave And Foundation Vents

Torn or uncovered vents can allow moisture and pests to enter the attic or crawlspace, leading to mold or structural damage. If plumbing, ducting, ceiling, or flooring in the home is properly insulated, foundation and eave vents should remain open year-round but should always be securely covered by a screen. To prevent issues, torn or open vents should be repaired or replaced as soon as possible. It is important to check vents for proper air flow regularly to ensure they are not blocked by debris or other materials.

10. Out-Of-Date Smoke And Carbon Monoxide Detectors

Smoke & CO detectors that are out of date may not function properly, increasing the risk of fire or carbon monoxide poisoning. Older detectors may not be equipped with the latest safety features and technologies, which could mean that they don't detect smoke or carbon monoxide as effectively as newer models. Replacing out-of-date smoke and CO detectors is an important step in maintaining a safe home environment and it is required by law when homes changes ownership. The lack of proper smoke and CO detectors will pose a problem when selling a home, as they are required by building codes and state law, and they are an appraisal requirement. Detectors must be replaced if they are more than 10 years old or they don't comply with manufacturer requirements.

11. Lack Of GFCI Outlets In Kitchen, Bathroom, and Laundry Room

The absence of GFCI outlets in a home can pose a significant safety hazard, as they are designed to protect against electrical shock and electrocution. Not having GFCI outlets in areas of a home that are susceptible to moisture, such as bathrooms, kitchens, and laundry rooms can increase the risk of electrical accidents.

Prevention is the most cost-effective method of maintaining a home.
