A low price may exclude access, fixture removal, permits, disposal, testing, or finish restoration rather than represent the same work.
Start with the desired outcome and verified evidence, then normalize each proposal. Separate required work from alternates and unknown concealed conditions. For urgent containment, ask for a second written phase before a broad permanent repair.
Keep this boundary: A price range on a directory or marketing page is not a quote for your property. Only the written project scope can define the comparison.
