Brick century homes, real basements, and four hard seasons: St. Louis is a market where knowing old construction is the whole job. When you compare insulation quotes in St. Louis, 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.
