    Companies may include different labor, materials, warranty coverage, travel, cleanup, disposal, or inspection support. Ask each company to quote the same scope before comparing.
  • Should I choose the lowest estimate?
    Not automatically. Compare price with review history, profile detail, communication, warranty terms, and whether the company seems like a strong fit for your project.
