What We Evaluate During Every Property Assessment
Every Property Assessment includes a thoughtful evaluation of the exterior conditions that affect your home's appearance, performance, and long-term durability. We look for the common issues Pacific Northwest homes face so we can recommend the right care for your property.
Moss & Moisture
Moss growth and trapped moisture can accelerate wear on roofs, siding, and other exterior surfaces if left untreated.
Gutters & Drainage
Blocked gutters and poor drainage can lead to water overflow, staining, moisture intrusion, and premature exterior wear.
Algae, Grime & Seasonal Buildup
Organic buildup caused by Pacific Northwest moisture can reduce curb appeal and shorten the life of exterior surfaces.
Slippery Concrete & Walkways
Organic buildup on driveways and walkways creates slip hazards while diminishing your property's appearance.
