Fog, salt, hills, and Victorians: San Francisco homes are beautiful, complicated, and expensive to neglect. When you compare insulation quotes in San Francisco, ask every company the same three questions: are you licensed and insured for this exact work, who is actually showing up (your crew or a sub), and what does the warranty cover in writing.
