7 Home Inspection Findings That Deserve Your Full Attention

Written by Aaron Fetveit, Certified Master Inspector — 406 Home Inspection Pros | Serving the Flathead Valley, Montana

The home inspection findings that deserve your full attention are ones connected to safety, structural integrity, or significant repair cost — specifically: active water intrusion, roof condition, electrical safety, foundation movement, heating systems, plumbing deficiencies, and elevated radon.

Knowing which findings carry real weight — and which ones can wait — makes the whole report easier to navigate.

Your inspection report just hit your inbox. It is 40-plus pages. There are photos, observations, checkboxes, and what feels like an overwhelming number of flagged items. Before your stomach drops — take a breath. A long report does not mean a problem house. It means you hired a thorough inspector, which is exactly what you want.

The reality is that most findings are minor — loose outlet covers, caulk that needs refreshing, a dripping faucet. Those belong on a to-do list, not a panic list. But some findings are different. After thousands of inspections across the Flathead Valley — from older craftsman homes in Kalispell to lakefront properties near Bigfork to newer builds outside Whitefish — these are the seven categories our team consistently tells buyers to give their full attention.

1. Active Water Intrusion and Moisture Damage

Water is the most destructive force a home faces over time — and in Montana, where snowmelt, spring runoff, and freeze-thaw cycles are a yearly reality, moisture problems show up regularly. Our inspectors look for water intrusion at foundations, in crawlspaces, under rooflines, around windows and doors, and along basement walls.

Signs that warrant attention:

• Staining or efflorescence (white mineral deposits) on foundation walls
• Soft or spongy subfloor material — especially near bathrooms or exterior walls
• Persistent musty odor in crawlspaces or basements
• Deteriorated or absent vapor barriers in crawlspaces
• Evidence of past or active leaks around windows, roof penetrations, or at the base of walls

Crawlspace moisture is especially common in older Flathead Valley homes, where vapor barriers are absent or have broken down and seasonal ground saturation is simply part of life here. Left unaddressed, these conditions lead to wood rot, compromised floor joists, and mold. This is not a finding to defer.

2. Roof Condition — Including Ice Dam Damage

Ice dams form when heat escapes unevenly through the roof, melting snow that refreezes at the colder eave line. Over time, that trapped water migrates under shingles, soaks into sheathing, and stains or damages interior ceilings and walls. Many homeowners do not realize the damage is happening until it is already significant.

What our inspectors evaluate on the roof:

• Roofing material condition
• Flashing integrity at chimneys, valleys, and pipe penetrations
• Gutter attachment and proper drainage
• Attic evidence of past ice dam water infiltration — staining, deteriorated sheathing
• Ventilation issues that may be contributing to uneven snowmelt

A roof with visible material damage needs a contractor’s honest assessment of what repair or replacement will actually cost before you close.

3. Electrical Safety Concerns

Electrical defects are among the most serious findings in any inspection because the consequences of ignoring them — house fires, electrocution risk — do not announce themselves in advance.

Our inspectors follow InterNACHI’s Standards of Practice in evaluating the service panel, visible wiring, outlets, and all GFCI protection locations.

Older homes throughout the Flathead Valley sometimes still contain outdated configurations, improperly modified panels, or DIY electrical work that was not done correctly. Findings that require prompt follow-up by a licensed electrician:

• Double-tapped breakers (two wires on a single breaker not rated for it)
• Aluminum branch circuit wiring without compatible devices
• Missing GFCI protection in kitchens, bathrooms, garages, and exterior outlets
• Open or uncovered junction boxes
• Evidence of overloaded panels or unauthorized DIY modifications

4. Foundation and Structural Movement

Not every crack in a foundation is a crisis. Concrete shrinkage cracks are completely normal and appear in almost every poured foundation — they are cosmetic. What matters is the pattern, the width, and whether there is evidence of actual movement.

Frost heave is a real and recurring concern in Montana. When soil freezes deep — and it does here — it shifts footings and foundations over time, especially on properties with poor drainage, expansive soils, or inadequate footing depth. Signs to pay attention to:

• Stair-step cracking in block or brick foundations
• Horizontal cracks in poured concrete walls (especially with bowing)
• Doors or windows that no longer operate properly without explanation
• Gaps between walls and ceilings or floors

When our report documents crack patterns or other signs of movement, we recommend a structural engineer evaluate before you close. That is not meant to alarm — it is meant to make sure you have the full, honest picture of what you are buying.

5. Heating System Condition

In the Flathead Valley, a reliable heating system is not optional equipment. When temperatures drop to single digits in January — or below — a failing furnace becomes an emergency, not an inconvenience. That is why HVAC condition gets careful attention on every inspection we perform.

We evaluate furnaces, boilers, heat pumps, and wood-burning appliances for visible condition, operational performance, and proper installation. Findings that carry real implications:

• Cracked heat exchanger — a carbon monoxide risk that should never be minimized
• Wood stoves without proper clearances to combustible materials
• Improper gas or propane venting — incomplete combustion venting is a CO hazard
• Heating equipment that failed to operate during the inspection

6. Plumbing Deficiencies — Including Well Systems

Plumbing findings vary widely in severity — from a loose toilet to a failed water heater to sewage concerns. The ones that deserve full attention typically involve active leaks, improper drainage, water heater safety concerns, or supply line materials with known failure histories.

For properties outside city limits — and there are a lot of them throughout the Flathead Valley — well systems add an important layer. A well equipment inspection evaluates the pump, pressure tank, and associated components for proper function. A water test tells you what is actually in the supply. These tests are highly recommended and they are essential information for any rural property purchase.

• Active leaks at supply lines, drains, or fixtures
• Water heater missing pressure relief discharge tube
• Galvanized steel supply pipes showing corrosion or restricted flow
• Improper drainage slope — waste that does not drain correctly
• Aging well pump or pressure tank with signs of wear or low pressure

7. Elevated Radon Levels

Radon is a naturally occurring radioactive gas produced by uranium decay in soil and rock. It is colorless, odorless, and present throughout Montana. Here is the detail that matters most for Flathead Valley buyers: Flathead County is classified by the EPA as Zone 1 — the highest radon potential category, with predicted average indoor screening levels exceeding 4 pCi/L.

The Montana Department of Environmental Quality confirms that elevated radon levels are common throughout the state due to local geology. The EPA recommends mitigation when levels reach 4 pCi/L or above — and suggests considering action even between 2 and 4 pCi/L, since there is no known fully safe level. Radon is the second leading cause of lung cancer in the U.S. after smoking, and radon-related lung cancer is the leading cause among non-smokers.

How to Actually Use Your Inspection Report

An inspection report is not a pass/fail grade. It is an honest picture of what is there right now. Most homes — even well-maintained ones — will have findings. What matters is understanding which ones are routine, which need attention, and which should be addressed before you commit.

A practical way to work through it:

1. Start with the summary section — this is where the most significant findings are highlighted
2. Sort by category — safety hazards, recommendations, and maintenance items
3. Focus on the seven categories above — water, roof, electrical, foundation, HVAC, plumbing, radon
4. Ask your inspector to clarify anything unclear — we write reports in plain language and we are happy to walk through findings with you
5. Get contractor input on significant items — understanding actual repair cost helps you make an informed decision, not an emotional one

Our job does not end when the report is delivered. We want you to leave with a clear understanding of the home you are considering — not a list of technical terms that leaves you more confused than when you started. If you are wondering whether to attend your inspection in person, we cover exactly what to expect in our guide buyers attending home inspections.
