Topside Attic Insulation in Alaska
Topside Attic Insulation handles attic insulation and air sealing for homeowners across Alaska. We work under The Haven Standard, which means every job starts with a written price, a written scope, and a written warranty before anyone lifts a tool. We believe insulation should be measured, not guessed at, which is why we publish before-and-after blower-door numbers on every applicable job. You’ll see, in a single figure, how much conditioned air your home was losing before we arrived and how much it loses after we leave. That’s the performance change you actually paid for, documented.
Why Alaska Homeowners Choose Topside Attic Insulation
Alaska winters don’t negotiate. A house that leaks conditioned air is a house paying to heat the outdoors, and we’ve seen the difference a properly sealed attic floor makes when temperatures drop well below zero. Our crews seal first, then insulate, in that order. We will never blow insulation over an unsealed attic floor. Top plates, can lights, penetrations, any gap where warm air escapes into the attic, all get sealed before insulation is added. We’ve completed over 9,000 homes since 2016, and every single one left with a documented photo record and a written price agreed before work began. We source materials from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber; if a particular product fits your home better than another, we’ll use it. There’s no proprietary lock-in and no upsell at the door. We also offer a free second opinion on any written estimate. Bring us a competing quote and we’ll read it with you, line by line. Our 365-Day Done Right Promise means if it’s not done right, we make it right. That promise is backed by the written scope and warranty you receive before anyone starts.
Backed by the Haven Family

Topside Attic Insulation operates under The Haven Standard, five published clauses that govern every job across Alaska: the price in writing before work starts, a real arrival window with a named technician, crews that are licensed, insured and background-checked with the license number published, photographic evidence of what was found on every visit, and no upsell at the door. It’s a simple agreement, and agreeing to it is the entire condition of carrying the Haven name. That’s what the family contributes: a standard you can hold us to, and documentation that proves we met it.
