Send corrections and project questions.
Use email for calculator mismatches, factual corrections, editorial questions, or advertising policy questions. The clearest reports are the easiest for us to review quickly.
What to include for editorial corrections
If a guide needs correction, include the sentence or section that looks wrong, plus the source of the conflict if one exists. That helps us update the page faster and more precisely.
What not to send
We do not provide contractor bids, local code interpretation, or custom project consulting. Site guidance is meant for general planning and purchase prep.
