Services
Home Inspection
Our home inspections evaluate structural integrity, electrical and plumbing systems, HVAC functionality, and safety hazards. We provide detailed reports with photos and repair recommendations. Clients receive clear insights into a property's condition, helping buyers and sellers make informed decisions. Our process follows Oregon state standards.
Home Energy Scores
We conduct Portland-mandated Home Energy Scores to rate efficiency on a 1-10 scale. The assessment examines insulation, windows, heating systems, and appliances. Results include improvement suggestions to enhance efficiency and compliance. Reports are completed the same day as the assessment.
Radon Testing
Our 48-hour radon testing uses Sun Nuclear monitors to detect radioactive gas levels. Testing follows closed-house protocols to ensure accuracy. Results above 4.0 pci/L indicate mitigation needs. We follow NRPP-certified procedures for reliable, actionable data.
Indoor Air Quality Testing
We test for mold spores and irritants using Zefron pumps and Air-O-Cell cassettes. Samples are analyzed in certified labs to identify indoor air quality issues. Results compare indoor and outdoor particulate levels, guiding remediation efforts for healthier living environments.
Sewer Scopes
We perform video inspections of sewer lines to detect offsets, root intrusion, or blockages. Early identification of issues prevents costly repairs. This service is commonly scheduled during home inspections to assess underground infrastructure.
