Editorial standards
Useful guidance.
Honest limits.
Every page should help a homeowner understand the problem, ask a better question, or take an appropriate next step.
Source-backed explanations
We prioritize relevant government, public-health and building-science guidance. Sources are linked in guides. Contractor information may help explain available services, but does not independently prove outcomes or make a partner vetted.
No diagnosis from a symptom
We explain possibilities rather than claim that an odor, photograph or symptom proves a cause. Structural, medical and project-specific technical decisions belong with appropriately qualified professionals.
No invented credentials or proof
We do not create fake reviews, projects, offices, statistics, certifications or expert reviewers. Photos and illustrations are labeled according to their actual origin.
Review and corrections
Our guides are general educational resources. They have not been independently reviewed by a licensed contractor or engineer, and they do not replace an on-site assessment. We update pages when we find errors or when guidance changes.
