Topside Attic Insulation in Colorado
Topside Attic Insulation handles attic air sealing and insulation for homeowners across Colorado. Every job follows the same sequence: seal the attic floor first, then insulate. Before any work begins you receive a flat price in writing, a written scope, and a written warranty. After the crew leaves, you get a documented photo record and before-and-after blower-door numbers showing exactly how much conditioned air your home stopped losing. That’s the promise Topside makes as part of the Haven family, and it applies to every Colorado home we touch.
Why Colorado Homeowners Choose Topside Attic Insulation
Colorado’s climate punishes a leaky attic in both directions. Winter pulls heat out through unsealed top plates and can-light penetrations. Summer pushes hot air down into living spaces that should stay cool. Most insulation companies skip straight to blowing fiber, which buries the leaks instead of closing them. Topside won’t do that. Air sealing comes first, every time, because insulating over an unsealed attic floor is a waste of the homeowner’s money. Since 2016 we’ve sealed and insulated more than 9,000 homes under The Haven Standard, and every one of those jobs produced a documented record: photos of what we found, photos of what we changed, and blower-door numbers before and after. You can see the performance change you paid for in a single figure. We publish those numbers on every applicable job, not just when the result looks flattering. Materials come from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber. No proprietary product lock-in, so the recommendation matches your attic, not our inventory. If a competing written estimate is already in your hands, bring it to us. We’ll read it with you, line by line, at no charge.
Backed by the Haven Family

Haven has stood behind independent service companies since 1998, and every Topside Attic Insulation job in Colorado operates under the same five published clauses: the price in writing before work starts, a real arrival window with a named technician, licensed insured background-checked crews with the license number published, photographic evidence on every visit, and no upsell at the door. If anything falls short of the scope, the 365-Day Done Right Promise means we make it right. A haven is somewhere nothing bad is going to happen to you. That’s the standard.
