Topside Attic Insulation in Michigan
Topside Attic Insulation handles attic air sealing and insulation for homeowners across Michigan. We’re part of the Haven family, which means every job in this state runs on the same five published clauses: a written price before work starts, a real arrival window with a named technician, verified crews, documented evidence from the visit, and no upsell at the door. Since 2016, more than 9,000 homes have been sealed and insulated under this standard, and every one of them left with a written scope and a photo record. That’s the promise Michigan homeowners get, and it’s not negotiable.
Why Michigan Homeowners Choose Topside Attic Insulation
Michigan winters expose weak attic insulation faster than almost any climate in the country. The temperature swings here, from single-digit cold to humid summer heat, push conditioned air through top plates, can-light housings, and plumbing penetrations all year. Topside Attic Insulation handles the problem in the correct order: we seal first, then insulate. We will not blow insulation over an unsealed attic floor, because insulation slows heat transfer but does not stop air movement. On every applicable job, we publish before-and-after blower-door numbers so you can see the change in a single figure, not in our description of it. Materials come from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber, with no proprietary lock-in, so the product selection follows the house, not our supplier arrangement. Every job includes a written price and written warranty before anyone lifts a tool, a documented photo record when the crew leaves, and a 365-Day Done Right Promise: if it’s not right, we make it right. Michigan homeowners also get a free second opinion on any written estimate from another contractor. Bring us the quote and we’ll read it with you.
Backed by the Haven Family

Topside Attic Insulation is independently owned and operated, and the Haven name on the truck means the owner agreed to the Haven Standard: five clauses, published, covering written pricing, arrival windows, verified crews, evidence, and no door upsell. Haven does not pretend to be from Michigan. We are, and the documentation system, the buying power, and the standard are what Haven contributes to every job we do here.
