The Most Common Defects We Find in Minnesota Homes.

These are the conditions we document most often across the Lake Minnetonka west metro, drawn from the region's housing stock, tree canopy, and climate — representative patterns, not a count of any specific set of inspections.

Plumbing

Oak-Wilt Root Sewer Intrusion

Lateral failure is a five-figure repair the seller won't disclose — which is why we scope every inspection here.

Exterior

EIFS / Synthetic Stucco Moisture

Concealed EIFS moisture rots sheathing and framing silently and is one of the most expensive defects on upscale Minnetonka homes.

Roof

Cedar Shake Roof End-of-Life

An end-of-life shake roof is a major replacement and a Class 4 / insurance conversation that directly affects negotiation.

Roof

Ice Dams & Attic Bypass

Ice dams drive water under shingles and shake into walls — a recurring Glen Lake and Greenbriar problem that damages finishes.

Electrical

Federal Pacific / Zinsco Panel

These panels are a recognized fire-safety concern and routinely warrant replacement on older Glen Lake splits.

Electrical

Aluminum Branch Wiring

Aluminum branch wiring is a known fire risk and an insurability issue buyers must understand before closing.

Plumbing

Polybutylene Plumbing

Polybutylene failures cause sudden flooding and are an insurance and negotiation concern in Cherrywood and Sunset Pond builds.

Structure

Foundation Cracks & Movement

Structural movement and active water intrusion are deal-defining defects that benign cracks are not — knowing the difference matters.

Structure

Deck Ledger & Structural Rot

A failing deck ledger is a life-safety collapse risk and one of the most common significant findings on local inspections.

Plumbing

Improper Bath Venting

Improper bath venting is a leading hidden driver of attic mold and roof-deck rot in west-metro homes.
