Marshall Insulation

Marshall Insulation is a local Insulation contractor and licensed Contractor specializing in attic, wall, and crawlspace insulation upgrades that reduce energy bills and improve comfort in Phoenix homes and businesses. Schedule an attic evaluation and ask them to include thermal imaging and a duct-leakage check, plus a side-by-side comparison of blown-in cellulose/fiberglass versus spray foam with expected R-values and payback. Inquire about APS/SRP rebates, air sealing packages, and radiant barrier options suited for desert heat, along with a written warranty and a post-install inspection to verify even coverage depth. For new builds or retrofits, request a detailed quote that includes prep (baffles, bath fan venting), cleanup, and timeline, and confirm crew arrival windows so you can plan access and protect belongings.
