Documented
Reports cover the property from roof to crawlspace, with photos, readings and a summary of the items that matter most. Lab results are included where samples are taken.
Discreet
Your findings go to you and the people you choose. We’re respectful in occupied homes and careful with your privacy.

Mold inspection & testing
Mold is a moisture problem first.
Many of the mold problems we find are in new construction, often in crawlspaces that were closed up while the framing was still wet. The rest are in homes people have owned for years. Attic condensation during winter inversions is also common, as are slow plumbing leaks, across Idaho and Eastern Oregon.
Our mold inspections combine moisture mapping, thermal imaging and laboratory analysis to find where the water is coming from. Then we tell you what to do next.

Client reviews
In our clients’ words.
From 31 Google reviews, as of November 2026.
Read all reviews on GoogleBuilding Specs did a thorough home inspection. We were thrilled with the work done as well as the quick report we received.
The report was thorough, comprehensive, understandable and really helped us to have a good understanding of the condition of these homes.
The followup and willingness to go the extra distance to take care of the clients and agents is exceptional. I have worked with other inspectors in the past but none can compare to Building Spec.
