A few inches left up there
Plenty of attics here have only a few inches of old insulation left. If that layer is dry and sound, we seal the gaps and blow new fill over it rather than starting from bare joists.

What blown-in insulation does for your attic
Blown-in insulation in Duluth is loose fill, cellulose or fiberglass, blown through a hose across your attic floor so the ceiling below holds your heat better.
I'm the owner of Advanced Duluth Insulation Company, and most of the attic calls I get start with ice dams, a cold upstairs room or a power bill that keeps climbing. Blown-in is usually the right fix for an attic floor as long as the gaps underneath are sealed first, and that's the order we work in.
What moves the price is the size of your attic, how many inches are already up there, how many gaps need sealing and whether old insulation has to come out first. The schedule turns on those same checks, since wet material or old wiring gets dealt with before we blow anything, and on whatever the city asks for. When I come out for the estimate, I measure all of it and write up your figure.
Based in Duluth since 2023
We've worked out of Duluth since I started the business in 2023, and we also take jobs in Superior, Hermantown, Cloquet and other cities around the Twin Ports.
You'll hear what we found
When the work is done, I walk you through what we found up there, what we did and why, so you understand your attic and aren't left guessing about it.
A clean house when we leave
We protect the path to your attic hatch and clean up loose fill before we go, because insulation work shouldn't leave a mess in your hallway or closet.
How we do a blown-in attic, in order
On an attic, I work the way a kitchen works, with the prep done before the cooking starts. First I look at what's already up there, measure the inches and check for vermiculite, old wiring and wet or dirty material, because blowing fresh fill over a layer that's soaked or full of droppings just buries the problem. If the old layer has to go, insulation removal comes before anything else.
I'll also ask about your ceiling lights. The cellulose industry's own practice keeps heaters and recessed lights uncovered unless the fixture carries an IC rating, which says insulation can touch it, so we need to know which of yours have one. Then we seal the gaps around lights, pipes, wires and the attic hatch, and set baffles, short channels at the eaves that keep the vents open so the attic can still breathe.
Last, we blow the fill in an even layer across the whole ceiling, out to the edges, and pack it dense enough to guard against settling that would leave holes, which also slows air moving through it. Deep in the middle and thin at the edges is backward, so I watch the edges most. If you're comparing quotes, ask whether each one covers the whole ceiling and includes baffles, and if the attic is one part of a bigger plan, start with home insulation.
Attics and houses we see around Duluth
Story-and-a-half houses
These ceilings sit so close to the roof that there's often no room for enough insulation. Sealing and insulating where we can helps a lot with ice dams, though some may still form.
Old wiring in the attic
Some older homes still have knob and tube wiring. A Minnesota energy nonprofit says any that's live must come out, by a licensed electrician, before insulating or sealing, so I look for it first.
Low corners and odd framing
Loose fill gets into odd-shaped framing, low corners and the gaps around pipes and other obstructions that are hard to reach by hand, which suits the awkward attics in many older Duluth houses.

Questions about blown-in insulation in Duluth
Here are straight answers to what people ask me before an attic job, from cost and the order of work to old insulation and permits.
How much does blown-in attic insulation cost in Duluth?
Attic insulation in Duluth usually costs about $1,500 to $5,000 per job, and that's the going rate around here, not a quote from us. Where your attic lands depends on its size, what's already up there and how much sealing or removal it needs. I'll give you your own figure once I've looked at it.
Should air sealing come before adding more insulation?
Yes. The ceiling should be made airtight first, so warm, moist air from the house stays out of the attic, and then insulation goes on to cut heat loss. Adding insulation is a natural time to seal, since we're already up there, so we plan the two as one job.
What if my attic in Duluth has vermiculite insulation?
Leave it undisturbed and mention it when you contact us. The EPA advises assuming vermiculite may contain asbestos, and if you choose to remove it, a trained, accredited asbestos abatement contractor, separate from the company that assessed it, should do the work. We don't blow over it or move it until that's settled.
Do I need a permit for attic insulation in Duluth?
The City of Duluth requires a building permit for construction, alterations, repairs and similar changes to a building. Before work starts, I check the permit rules for your address with the city and tell you whether we'll pull the permit or what you'll need to do, and in Superior, Hermantown or Cloquet I check with that city instead.
Does an insulation contractor need a license in Minnesota?
Not always. The state's Department of Labor and Industry licenses residential contractors who work in more than one skill area, and it lists insulation under interior finishing, so a contractor who does only that one kind of work needs no state license. We're fully licensed and insured.
How much insulation should an attic have in Minnesota?
One Minnesota energy nonprofit says a properly air-sealed attic should be insulated to R-50, R-value being how well insulation slows heat. That figure assumes the sealing is done first, which is part of why we start there. Ask each contractor what level the finished attic will reach, and I'll tell you on ours.
