Topside Attic Insulation in Vermont
Topside Attic Insulation is the Vermont arm of the Haven family, focused on one thing: attic insulation that works because the attic is sealed before a single bag of material goes in. Homeowners across Vermont get the same written-price commitment, the same documented photo record, and the same before-and-after blower-door measurement that every Haven company provides. We do not blow insulation over an unsealed attic floor, and we do not leave a job without showing you the numbers. That is not an upsell pitch. That is the job.
Why Vermont Homeowners Choose Topside Attic Insulation
Vermont winters do not forgive a leaky attic. Warm air rises, finds every penetration in the ceiling plane, and pulls cold outside air in through the rim joists and foundation. The symptom is a furnace that runs constantly and rooms that never feel warm. The fix is not more insulation on top of the problem. It is air sealing first: top plates, can lights, plumbing and electrical penetrations, the access hatch. Sealed first, then insulated, in that order. Topside Attic Insulation has sealed and insulated more than 9,000 homes since 2016, and every single one started with a written price before work began and ended with a documented record when the crew left. Our technicians are background-checked and uniformed. Our materials come from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber, and we will recommend whichever product actually fits your house, not whichever one we have a deal on. Before we start, you get a flat price, a written scope, and a written warranty. After we finish, you get a blower-door number that tells you exactly how much conditioned air your Vermont home was losing before and how much it loses now. We also publish those numbers. If another contractor gives you a written estimate, bring it to us and we will read it with you, line by line, at no charge.
Backed by the Haven Family

Haven’s entire condition for carrying the name is the Haven Standard: five clauses, published, and every company held to all five. Clause 1 is the one that matters most to Vermont homeowners: have it in writing. Flat price, written scope, written warranty, before anyone lifts a tool. Clause 5 is the one that matters second: no surprises, no door upsell, no scope creep. Every Topside Attic Insulation job is protected by the 365-Day Done Right Promise. If it is not done right, we make it right, and the written scope you got before we started is exactly what we are held to. A haven is somewhere nothing bad is going to happen to you. That is the standard we signed.
