Topside Attic Insulation in Maine
Topside Attic Insulation brings attic air sealing and insulation to homeowners across Maine under the Haven family’s published standard. We operate as an independently owned and operated insulation contractor serving the state, with crews that seal first, insulate second, and document every step. Since 2016, the businesses carrying the Haven name have sealed and insulated more than 9,000 homes, and every one of those jobs started with a written price and ended with a written record. Maine winters are unforgiving, and an attic that leaks conditioned air is a tax you pay every month from November through April.
Why Maine Homeowners Choose Topside Attic Insulation
Maine’s heating season runs long and cold, which makes a leaky attic the most expensive problem in the house that you can’t see. Topside Attic Insulation approaches every Maine job the same way: we air seal before we insulate. That means top plates, can lights, wire penetrations, and the gap around the chimney chase get sealed before any insulation goes down. It’s the difference between owning a warm hat and owning a hat with holes in it. We won’t blow insulation over an unsealed attic floor because that just buries the problem, it doesn’t fix it. Once the sealing is done, we install materials from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, or GreenFiber, chosen for the specific attic we’re working in rather than locked to one manufacturer. Maine homeowners who research before they call tend to ask the same question: how do I know the work actually did anything? We answer that with a blower-door test performed before the work begins and again after it’s finished. The two numbers, side by side, show exactly how much conditioned air the house stopped losing. It’s a measurement, not an opinion. Every visit also includes a documented photo record, so you’ll see what the crew saw: the sealed penetrations, the installed depth, the finished attic. If you bring us a written estimate from another insulation contractor, we’ll read it with you line by line, free, and explain what’s in it and what’s missing.
Backed by the Haven Family

Topside Attic Insulation carries the Haven name, which means one thing for Maine homeowners: the Haven Standard applies to every job. Clause 1 puts the price in writing before anyone lifts a tool. Clause 2 puts a real arrival window and a named technician on the schedule. Clause 3 covers licensed, insured, background-checked crews. Clause 4 means evidence on every visit, and Clause 5 means no upsell at the door. Plus the 365-Day Done Right Promise: if it’s not right, we make it right. The name is the guarantee.
