Topside Attic Insulation in Alaska
Topside Attic Insulation Co sales & service seals and insulates homes across Alaska under a simple rule: the air sealing happens first, then the insulation goes in over it. That order is not negotiable, because blowing insulation over an unsealed attic floor is how you pay twice. Since 2016, we’ve worked on more than 9,000 homes, and every one of those jobs started with a written price and ended with a documented record. Alaska homeowners get the full Haven family promise: flat pricing in writing, a named technician, and before-and-after blower-door numbers showing exactly what changed.
Why Alaska Homeowners Choose Topside Attic Insulation
Most insulation contractors will happily blow cellulose over whatever is already in your attic. We won’t, because an attic full of new insulation with unsealed top plates, can lights and penetrations is still leaking conditioned air straight through the ceiling. In Alaska, where heating season runs most of the year, that is not a minor detail. Our crews air seal first, then insulate with materials from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec or GreenFiber, whichever actually fits the job rather than whichever we happen to stock. Then we run a blower-door test before and after, so you see the pressurization number that tells you how much air your house was losing and how much it loses now. That number goes on your record, not in a sales pitch. Every visit includes a documented photo record, and every job is backed by our 365-Day Done Right Promise. Bring us a competing written estimate and we will read it with you, line by line, for free. We publish that offer because most insulation quotes hide their assumptions in the fine print. Ours are written down before anyone lifts a tool.
Backed by the Haven Family

Haven was formed in 1998 to buy local home-service companies that were already doing the work properly and were about to be bought by someone who would stop. The deal is simple: the local brand, the crews and the name stay exactly as they are. What Haven adds is the standard, five published clauses covering the one thing customers actually complain about, which is not knowing. Clause 1 is the one we mention most: flat price, written scope, written warranty, before anyone starts. That applies to every Topside Attic Insulation job across Alaska, no exceptions.
