"Safeguard your Investment, hire a Licensed Professional to inspect your property"

Timberline Inspectors are qualified to inspect Commercial, Residential and Agricultural building types. We use a proprietary software program to produce fast, thorough reports with captioned photos and diagrams of the items in the report.  Most home inspection reports for an average sized home can be inspected and the report turned over to the client in less than three business days.

Timberline Inspections has the latest testing equipment to diagnose the systems in the property.  Our initial Radon Test(s) are run using the latest digital testing equipment and as a back-up we also test with the traditional samplers and get a certified lab report.  The Digital Radon Monitoring Equipment will give the quickest results so there will be no delays in your transaction. This Preliminary Radon Test will be conducted and delivered in less than three business days with the building inspection report. The digital results can be collected in as little as 48 hours, whereas the lab test takes 48 hours in the closed building and then another three business days for the Certified Lab Analysis.  But it is our policy that we want a Nationally Certified Laboratory verifying all of our Radon Tests.  The preliminary digital monitoring data is within 1 point +/- of the Certified Lab Analysis 85% of the time if the tests are conducted side by side, and consecutively.

A Timberline Residential and Commercial Building Inspection, LLC ®  Standard Residential (Home) Inspection in most cases includes:

The Standard Residential (Home) Inspection will inspect and record the readily accessible, visually observable abnormal or hazardous conditions inside and on the exterior envelope of the residence.

The Standard Residential (Home) Inspection will inspect and record the readily accessible, visually observable defects and hazardous conditions and a Contractor can be contacted by the Client to perform further testing and repair, correct, or mitigate the conditions.

Some examples that are tested in the Standard Residential (Home) Inspection include, but are not limited to:

  • High moisture content in floor, wall or ceiling materials;
  • Asbestos and other Environmental Hazards such as Lead Paint or Water Pipes;
  • Potentially dangerous Structural Defects;
  • Hazardous Electrical conditions;
  • Leaking Gas or Sanitary Drain Piping;
  • The presence of high levels of Carbon Monoxide
  • Mold, Mildew and possible Infestations by insects or other pests

Timberline Residential and Commercial Building Inspection, LLC ® endeavors to perform all inspections in substantial compliance with the Standards of Practice of International Association of Certified Home Inspectors® (InterNACHI) and the Professional Home Inspection Institute ® (PHII) and the National Society of Home Inspectors® (NSHI). As such, we inspect the readily accessible, visually observable, installed systems and components of a home as designated in the PHII® The Property Inspection Report contains observations of those systems and components that, in the professional judgment of the inspector, are not functioning properly, significantly deficient, unsafe, or are near the end of their service lives. If the cause for the deficiency is not readily apparent, the suspected cause or reason why the system or component is at or near end of expected service life is reported, and recommendations for correction or monitoring are made as appropriate. When systems or components designated in the PHII® Standards are present but are not inspected, the reason(s) the item was not inspected is reported as well.

The report is effectively a snapshot of the house—recording the conditions on a given date and time. Home inspectors cannot predict future behavior, and as such, we cannot be responsible for things that occur after the inspection. If conditions change, we are available to revisit the property and update our report.
