Topside Attic Insulation in Oregon
Topside Attic Insulation handles the part of the house Oregon homeowners never see: the attic floor, the top plates, the can lights, the penetrations. We seal first, then insulate, and we publish the before-and-after blower-door numbers on every applicable job so you can see the performance change you paid for. Every Oregon project starts with a written price and ends with a documented record. No exceptions, no verbal estimates, no work without your signature on a scope. That’s the Haven Standard, and Topside has worked under it since 2016.
Why Oregon Homeowners Choose Topside Attic Insulation
Oregon’s climate punishes a leaky attic. Wet winters drive moisture into unsealed cavities, summer heat pushes conditioned air out through top plates and can-light housings, and the result is a house that’s expensive to heat, expensive to cool, and hard to keep comfortable. Topside’s approach is different from most insulation contractors in one specific way: we will not blow insulation over an unsealed attic floor. Air sealing comes first. Top plates, can lights, plumbing and electrical penetrations, duct chases, and interior wall cavities get sealed before any material goes down. Then we insulate using materials from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber. No proprietary product lock-in, which means the material choice is based on your attic, your structure, and your goals, not on what we’re obligated to sell. Every job ends with a documented photo record and a blower-door number that shows, in a single figure, how much conditioned air the home was losing before and after. Since 2016, more than 9,000 homes across Oregon have been sealed and insulated by Topside crews, and every one of those jobs started with a written price and ended with a written record.
Backed by the Haven Family
Topside Attic Insulation carries the Haven name because we agreed to be held to five published clauses. Written price before work starts. A real arrival window with a named technician. Crews that are licensed, insured, and background-checked. Photographic evidence of what was found on every visit. And no upsell at the door. The 365-Day Done Right Promise covers every Topside job across Oregon: if it’s not done right, we make it right. Independently owned and operated, with the documentation to prove it.
