Topside Attic Insulation in New Hampshire

Topside Attic Insulation in New Hampshire

Topside Attic Insulation insulates and air-seals homes across New Hampshire under the Haven Standard, the five written promises every Haven company signs before carrying the name. We treat air sealing as a prerequisite, not an upsell, and we publish before-and-after blower-door numbers on every applicable job so you see exactly what changed. Since 2016, our crews have sealed and insulated more than 9,000 homes, each one with a written price before work began and a documented record when the crew left.

Why New Hampshire Homeowners Choose Topside Attic Insulation

Most insulation contractors will happily blow cellulose over an unsealed attic floor and call it done. We won’t. Envelope seals first, then insulates, in that order. Top plates, can lights, wire penetrations and plumbing chases get sealed before any insulation goes down, because insulating over leaks just makes a warmer attic and the same drafty rooms below. Then we measure the difference. Every applicable job ends with a before-and-after blower-door number, a single figure showing how much conditioned air the home was losing and how much it’s losing now. New Hampshire winters punish leaks in ways milder climates don’t, and a blower-door test is the most honest way to prove the work did something. We also don’t lock you into one manufacturer’s product line. Our crews work with materials from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec and GreenFiber, matched to your house rather than to our supply agreement. And if the work isn’t right, the 365-Day Done Right Promise means we come back and make it right.

Bring us a competing written estimate and we’ll read it with you, line by line, for free. That’s how confident we are in what we’d write. Every visit also includes a documented photo record, so you can see what we saw in your attic, rim joists or crawlspace without climbing up yourself.
