Exterior Water Intrusion

Exterior Water Intrusion Repair Minnesota

Protect Your Home or Building from Costly Moisture Damage

Exterior water intrusion is one of the most common and costly issues faced by homeowners and property managers across Minnesota—especially in buildings with stucco siding or EIFS systems. At Donnelly Stucco & Exteriors, we specialize in identifying, repairing, and preventing water intrusion and moisture damage to protect your property’s structure, safety, and value.

What Is Exterior Water Intrusion?
Water intrusion occurs when moisture enters the building envelope through cracks, failed flashing, improper sealing, or poor drainage systems. Over time, this trapped moisture can cause:

-Mold and mildew growth

-Rotted framing and sheathing (See Pictures Below)

-Interior wall damage and staining

-Insulation breakdown

-Structural deterioration (See Pictures Below)

Signs You May Have Water Intrusion

-Cracks in stucco or bulging walls

-Water stains on ceilings or interior drywall

-Peeling paint or soft spots around windows and doors

-Musty odors or mold growth

-Leaks during or after rain

-Deterioration around rooflines or flashing
