Common Home Inspection Findings in Western Washington

Ground Fault Circuit Interrupter (GFCI) outlets are designed to reduce the risk of electrical shock in areas where water may be present.

During a home inspection, GFCI protection is commonly recommended in locations such as:

• kitchens

• bathrooms

• garages

• exterior outlets

• laundry areas

Older homes may not have GFCI protection installed.

While this condition is common, upgrading outlets to GFCI protection is generally recommended as a safety improvement.

Roof flashing is installed around roof penetrations and roof edges to direct water away from vulnerable areas.

Common flashing issues identified during inspections include:

• missing drip edge flashing

• improperly installed flashing

• deteriorated sealant

• exposed fasteners

Flashing problems do not always indicate roof failure but may require repair to help prevent water intrusion.

Small cracks in concrete foundations are common in many homes and are often related to normal settlement.

Hairline or narrow cracks are frequently considered cosmetic or typical settlement.

However, larger cracks, horizontal cracks, or cracks associated with movement may warrant further evaluation.

A home inspection can help identify visible structural conditions that may require additional review.

Exterior sealant around windows, siding joints, and trim helps prevent water intrusion.

Over time, sealants can:

• dry out

• crack

• separate from surfaces

Resealing exterior joints is a common maintenance item for many homes and helps protect the building envelope.

Homes in Western Washington commonly have crawlspaces.

Moisture in crawlspaces can occur due to:

• poor drainage

• inadequate ventilation

• missing vapor barriers

• plumbing leaks

Managing crawlspace moisture is important to help reduce the potential for wood deterioration or mold growth.

Home inspectors often evaluate crawlspaces for visible moisture conditions during an inspection.

Many home buyers in Western Washington choose to include a sewer scope inspection when purchasing a home.

A sewer scope involves inserting a small camera into the sewer line to identify potential issues such as:

• root intrusion

• pipe deterioration

• blockages

• offsets or damage

This inspection can help identify conditions that may not be visible during a standard home inspection.

Older homes sometimes have two-prong outlets, which typically indicate that the electrical system may not include modern grounding. Grounding provides an additional layer of safety for electrical devices. While two-prong outlets can still function, they may not meet modern expectations for electrical safety. Some homeowners upgrade outlets or install GFCI protection to improve safety and compatibility with modern appliances.on

Some homes built in the late 1960s and early 1970s used aluminum branch wiring instead of copper. Aluminum wiring can expand and contract more than copper and may require special connectors or repairs to reduce potential fire risks. When aluminum wiring is identified during an inspection, further evaluation by a licensed electrician is often recommended.

Federal Pacific electric panels were installed in many homes between the 1950s and 1980s. Some studies have raised concerns about the reliability of certain breakers in these panels. Because of this, many electricians recommend upgrading the panel as a precautionary improvement. If one of these panels is present in a home, buyers may wish to consult with a licensed electrician.

Ungrounded outlets are commonly found in older homes that were built before modern grounding practices were standard. Grounding provides an additional safety path for electrical current and helps reduce shock risks. While ungrounded outlets may still operate normally, upgrading them or installing GFCI protection can improve safety.

Drip edge flashing is a thin metal strip installed along roof edges to direct water away from the roof structure and into the gutters. Some older roofs were installed without drip edge flashing. While not always immediately problematic, installing drip edge flashing during roof repairs or replacement can help protect roof edges and fascia boards from moisture damage.

7. Roof Flashing Problems

Roof flashing helps prevent water intrusion around roof penetrations such as chimneys, vents, and skylights. During a home inspection, issues such as missing flashing, damaged flashing, or deteriorated sealant may be noted. Flashing repairs are common maintenance items that help prevent potential roof leaks.

8. Curling or Delaminating Roof Shingles

Roof shingles can curl, crack, or delaminate as they age and are exposed to weather conditions. These conditions may indicate normal aging of roofing materials. When shingles show signs of deterioration, homeowners may begin planning for future roof maintenance or replacement depending on the overall roof condition.

9. Roof Life Expectancy

Many buyers ask how long a roof will last. Roof lifespan depends on materials, installation quality, and environmental conditions. Asphalt shingle roofs often last 20–30 years under typical conditions. A home inspection can identify visible signs of aging but cannot predict the exact remaining life of a roof.

10. Moss Growth on Roofs

Moss commonly grows on roofs in wet climates like Western Washington. Moss can trap moisture against roofing materials, which may contribute to premature deterioration. Regular roof cleaning and maintenance can help reduce moss growth and extend the life of the roof.

11. Foundation Cracks

Small cracks in concrete foundations are common and often occur due to normal settlement. Hairline or narrow vertical cracks are typically considered typical settlement conditions. Larger cracks or cracks associated with movement may require additional evaluation to determine their significance.

12. Settlement Cracks in Drywall

Minor cracks in drywall are common in many homes and often occur as buildings naturally settle over time. These cracks are typically cosmetic and can often be repaired easily. However, significant cracking or repeated movement may warrant further evaluation.

13. Uneven or Sagging Floors

Slightly uneven floors are common in older homes due to normal settlement or framing variations. More significant floor sagging may indicate structural movement or framing concerns. A home inspection can identify visible conditions and recommend further evaluation if needed.

14. Crawlspace Moisture

Crawlspaces in Western Washington homes often experience moisture due to rainfall, drainage conditions, or ventilation issues. Excess moisture can contribute to wood deterioration or mold growth over time. Crawlspace inspections typically evaluate drainage, vapor barriers, ventilation, and visible moisture conditions.

15. Water Heater Life Expectancy

Water heaters generally last between 8–12 years depending on maintenance and usage. During a home inspection, the approximate age of the water heater may be noted along with any visible issues. Older water heaters may still function properly but could be nearing the end of their typical service life.

16. Galvanized Plumbing Pipes

Galvanized steel pipes were commonly used in older homes but can corrode internally over time. This corrosion may eventually restrict water flow or lead to leaks. When galvanized plumbing is present, homeowners sometimes plan for eventual replacement with modern materials.

17. Polybutylene Plumbing

Polybutylene piping was used in some homes between the 1970s and 1990s. Over time it was found that this material can deteriorate when exposed to certain chemicals in water supplies. Because of this, many homeowners choose to replace polybutylene plumbing with more modern materials.

18. Low Water Pressure

Low water pressure in a home can be caused by several factors including plumbing restrictions, aging pipes, municipal supply issues, or pressure regulator problems. During an inspection, basic water flow observations may be made, but detailed diagnosis may require a plumbing professional.

19. Wood Rot or Exterior Deterioration

Wood siding, trim, and other exterior components can deteriorate over time when exposed to moisture. This is especially common in damp climates. Regular maintenance such as painting, sealing, and replacing damaged materials helps protect exterior surfaces.

20. Missing Siding Flashing

Flashing installed behind siding joints helps direct water away from wall structures. Missing or improperly installed flashing may allow moisture intrusion over time. Proper flashing installation helps improve the durability of exterior wall systems.

21. Exterior Caulking Maintenance

Exterior caulking around windows, doors, and siding joints helps prevent water intrusion. Over time, caulking can dry out, crack, or separate from surfaces. Reapplying exterior sealant is a common maintenance task that helps maintain a home's weather resistance.

22. Poor Drainage Around the House

Water should generally drain away from the foundation of a home. Poor drainage can allow water to collect near the structure, potentially contributing to moisture problems in crawlspaces or basements. Improving grading or drainage systems can help reduce moisture issues.

23. What Happens if a Home Inspection Finds Problems?

Most home inspections identify some issues, even in well-maintained homes. Inspection findings often include a mix of maintenance items, minor defects, and occasionally larger repair concerns. Buyers typically review the report with their real estate agent to determine whether repairs should be requested or negotiated.

24. Should Buyers Walk Away After a Bad Inspection?

Not every inspection finding is a reason to cancel a purchase. Many issues can be repaired or negotiated during the home buying process. A home inspection helps buyers understand the condition of the property so they can make an informed decision.

25. Understanding Repair Costs After an Inspection

After receiving a home inspection report, buyers often want to understand potential repair costs. Contractors can provide repair estimates for specific issues identified during the inspection. Understanding potential repair costs can help buyers budget for maintenance or negotiate repairs.
