Topside Attic Insulation in Ohio
Topside Attic Insulation performs attic air sealing and insulation work across Ohio under the Haven Standard, the five-clause operating agreement every Haven company signs before taking a single job. For Ohio homeowners, that means a written price before any work starts, a named technician with a real arrival window, background-checked crews, photographic evidence of what was found and done, and no upsell at the door. We treat air sealing as a prerequisite, not an optional add-on. Every attic gets sealed at the top plates, can lights, and penetrations before insulation goes in. Then we measure the result with before-and-after blower-door numbers and put those figures in your hands.
Why Ohio Homeowners Choose Topside Attic Insulation
Ohio winters push conditioned air out of attics, and Ohio summers pull hot, humid air down through ceiling penetrations. The fix that lasts is sealing first, then insulating. Topside Attic Insulation has never blown insulation over an unsealed attic floor, and we won’t start now. The sequence matters because insulation slows heat transfer but does not stop air movement. A sealed attic with R-49 or R-60 insulation is a different building than an unsealed attic with the same R-value. We know because we measure it. After every applicable job, we publish before-and-after blower-door numbers, a single figure showing how much conditioned air the home was losing before our crew arrived and how much it loses after they leave. Ohio homeowners who want evidence rather than assurances see the actual pressurization change in writing. Materials come from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber. That means we specify what the house needs, not what a single supplier wants us to move. Since 2016, more than 9,000 homes across the state have been sealed and insulated this way. Each one started with a written price and ended with a documented record.
The 365-Day Done Right Promise applies to every job. If it is not done right, we make it right. And because every project includes a documented photo record, you will see what was found in your attic, what was sealed, and what was installed. Bring us a competing written estimate and we will read it with you line by line, no charge. That is the free second opinion we offer on every written quote. Our technicians are background-checked and uniformed. Calls are answered by a live person, day or night.
Backed by the Haven Family

Haven was formed in 1998 with a simple bet: leave good home-service companies alone, keep their names and crews, and standardize only what customers actually complain about, which is not knowing. Not knowing the price before the van arrives. Not knowing who is coming into the house. Not knowing what was found or what was done. The Haven Standard fixes that with five published clauses. Clause 1 is the one Ohio homeowners notice first: a flat price, written scope, and written warranty before anyone lifts a tool. Every Topside Attic Insulation job across Ohio carries that condition, from the first measurement to the final blower-door reading.
