WA Inspection Red Flags Buyers Should Never Ignore (2025 Guide)

1. Washington Buyers: Not All Inspection Issues Are Equal

When you’re buying a home in Washington — whether in Tacoma, Puyallup, Lacey, Bonney Lake, or anywhere near JBLM — an inspection is one of the most important parts of the process.

But here’s the part that surprises most buyers:

Not everything on the inspection report is a red flag.

Some items are normal “home ownership” tasks. Others are bigger issues that can cost thousands later.

This guide breaks down the inspection red flags that matter — the ones that deserve negotiation, repair credits, or a second thought before moving forward.

2. The Biggest Red Flag: Active Water Intrusion

Water is Washington’s #1 problem — and buyers should never ignore it.

Warning signs include:

  • Soft spots in flooring

  • Moisture around window sills

  • Stains on ceilings or walls

  • Musty smells

  • Cracks near the foundation

  • Standing water in the crawlspace

  • Water staining near the chimney

Why it matters

Moisture in Washington homes can lead to:

  • Mold

  • Rot

  • Structural damage

  • Electrical hazards

  • Expensive remediation

This is one of the highest-priority issues you can negotiate — or walk away from if the seller won’t address it.

 

3. Roof Problems — Especially in Washington’s Climate

Roofs matter more here than in sunny states.

Red flags include:

  • Missing shingles

  • Moss buildup

  • Soft spots

  • Exposed sheathing

  • Curling shingles

  • More than two layers of roofing

  • Evidence of old leaks

Most Washington buyers can expect a roof with 5–10 years left — that’s normal.
But a failing roof?
That’s a negotiation moment.

4. Electrical Hazards — A True Dealbreaker

Electricity is not a DIY area.

Major red flags:

  • Federal Pacific or Zinsco panels

  • Exposed wiring

  • Overloaded circuits

  • Double-tapped breakers

  • Missing GFCI outlets near water

  • Aluminum wiring

  • Flickering lights

These panels are common in older Tacoma, Lakewood, and Spanaway homes.
Replacing an electrical panel can cost $2,000–$6,000, sometimes more.

Always take this seriously.

 

5. Structural Problems (This Is Where We Hit “Big Money” Territory)

These issues are rare — but when they show up, they matter.

Big red flags include:

  • Foundation cracks wider than 1/4 inch

  • Rotten support beams

  • Sloping or uneven floors

  • Wall separation

  • Significant settling

  • Bowing walls

These issues usually require:

  • Structural engineers

  • Major repairs

  • A deeper evaluation

If you’re seeing these, we slow down and take a hard look before moving forward.

 

6. Plumbing Problems — Especially in Older WA Homes

Washington has many homes built before 1980, especially in Tacoma, Steilacoom, and older Lakewood neighborhoods.

Red flags include:

  • Slow drains

  • Sewer backups

  • Galvanized pipes

  • Visible corrosion

  • Leaks under sinks

  • Low water pressure

One thing Washington buyers should always get:
A sewer scope.

It’s the difference between peace of mind and a $15,000 sewer replacement.

 

7. Septic Issues — A Major Red Flag in Rural WA

If you’re buying in Graham, Eatonville, Orting, Spanaway, Yelm, or anywhere with acreage, you may be on septic.

Red flags:

  • Ponding water above the drain field

  • Strong sewage smell

  • Backups

  • Very old systems

  • No records of pumping

  • Failed inspection results

Septic repairs can cost $8,000–$25,000, so these deserve serious attention.

 

8. HVAC Problems — Comfort AND Safety

Washington buyers don’t always think about HVAC because our climate is mild… until they realize replacement is expensive.

Red flags include:

  • Non-functional furnace

  • Gas leaks

  • Cracked heat exchanger

  • HVAC units older than 20 years

  • No recent servicing

  • Rust or corrosion

If the furnace is unsafe, we address it immediately.

 

9. Mold or Mold-Like Substances (Especially in Crawlspaces)

Mold is extremely common in WA, especially in:

  • Crawlspaces

  • Attics

  • Bathrooms

  • Laundry rooms

Red flags include:

  • Heavy mold in attic sheathing

  • Mold around windows

  • Mold near plumbing

  • Mold in insulation

This isn’t always a dealbreaker — but it is a negotiation opportunity.

 

10. Attic Problems Often Overlooked

The attic tells the real story of the home.

Red flags include:

  • Mold on sheathing

  • Poor insulation

  • Exposed electrical

  • Animal infestation

  • Ventilation issues

Attic remediation can get expensive, so these issues deserve attention.

 

11. Deck Hazards — Very Common in Washington

Especially with our wet climate, decks take a beating.

Red flags include:

  • Rot

  • Loose railings

  • Soft wood

  • Failing supports

  • Improper flashing

Deck safety is a big issue for inspectors and insurance companies.

 

12. Chimney, Fireplace, and Wood Stove Issues

In Washington, many homes have wood-burning fireplaces.

Red flags:

  • Cracked mortar

  • Damaged flue

  • Creosote buildup

  • Missing spark arrestor

  • No chimney cap

These can be negotiable fixes — but still important.

 

13. The Difference Between Normal Wear and Real Problems

Not a red flag:

  • Minor drywall cracks

  • Paint imperfections

  • Worn carpet

  • Cosmetic updates

  • Old appliances that still work

  • Faded exterior paint

Actual red flags:

  • Water

  • Structure

  • Safety

  • Sewer or septic

  • Electrical

  • Foundation issues

Knowing the difference helps you buy confidently without walking away for the wrong reasons.

 14. When a Red Flag Should Make You Pause (Or Walk Away)

Walk away when:

  • The seller refuses to repair major safety issues

  • Repairs exceed your budget

  • The home has multiple major systems failing

  • The home is priced too high for the condition

Pause and reconsider when:

  • You need contractor bids

  • You want second opinions

  • Repairs might be credit-eligible

  • You’re unsure how to negotiate

Keep moving forward when:

  • Issues are normal maintenance

  • Problems are solvable with credits

  • Price already reflects condition

 

15. How to Use Red Flags to Your Advantage When Negotiating

Inspection issues aren’t always bad news — they can be leverage.

Buyers often secure:

  • Repair credits

  • Price reductions

  • Seller-paid fixes

  • Seller-paid warranties
