Topside Attic Insulation in Connecticut
Our Topside Attic Insulation Co services insulate and air-seal homes across Connecticut under The Haven Standard, the five-clause promise that has governed every job since 2016. Homeowners get a written price before work starts, a named technician with a real arrival window, background-checked crews, photo documentation of what was found, and no upsell at the door. We publish before-and-after blower-door numbers on every applicable job, so you can see the performance change you paid for, not just hear about it. We’ve sealed and insulated more than 9,000 homes, and every one left with a written record.
Why Connecticut Homeowners Choose Topside Attic Insulation
Our position is simple: sealing comes first, insulation second. We will never blow insulation over an unsealed attic floor. Top plates, can lights, wiring penetrations, chase ways - those get sealed before any material goes in. In Connecticut’s climate, with winters that settle into the teens and summers that hold humidity for weeks, that sequencing matters. A home that is insulated without being sealed is still losing conditioned air through paths insulation cannot reach. The blower-door test shows the difference in a single number. Before the work, the house leaks at a measurable rate. After, that number drops, and we hand it to you in the job record. Not an estimate. A measurement.
The materials come from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber. No proprietary product lock-in. We choose what the house actually needs, and the written scope tells you what it is and what it costs before anyone lifts a tool. If you already have a written estimate from another contractor, bring it to us. We will read it with you at no charge and tell you what it covers and what it doesn’t.
The 365-Day Done Right Promise applies to every job. If it’s not done right, we make it right. That is not a slogan. It is written into the scope and the warranty you receive before work begins. Every visit also includes a documented photo record. You see what we found, what we did, and what changed.
Backed by the Haven Family

Haven was formed in 1998 to buy good home-service companies before someone else could buy them and strip out what made them good. The Haven Standard is five clauses: written price before work starts, a real arrival window with a named technician, licensed and insured crews verified before they enter your home, photographic evidence of findings on every visit, and no door upsell. Topside Attic Insulation is independently owned and operated in Connecticut, and agreeing to those five clauses is the condition of carrying the Haven name. The price is in writing. The person is known. The evidence is yours.
