Does old attic insulation always have to come out?

No. Dry, clean insulation that's just too thin can usually stay, and new insulation goes on top after the air leaks are sealed. Removal makes sense when the insulation is wet, moldy, contaminated by rodents or animals, smoke-damaged, badly crushed, or in the way of work that has to happen on the attic floor.

Do you remove vermiculite insulation?

No. EPA advises treating vermiculite insulation as if it may contain asbestos: leave it undisturbed and hire a professional asbestos contractor if it needs to be removed. If Joe finds vermiculite, he stops and tells you. Once an asbestos contractor has handled it, Paramount can come back and insulate.

How is old insulation removed?

Loose-fill insulation is usually vacuumed out through a hose to a collection unit outside, so the material isn't carried through the house. Batts are bagged by hand. Then the attic floor is cleaned and the gaps are sealed before new insulation goes in.

What goes back in after removal?

Usually blown-in cellulose or fiberglass to the target depth for your attic. Joe explains the options at the free estimate.

Is removal included in an insulation estimate?

When removal is needed, it appears as its own line on Paramount's written estimate, along with disposal and the new insulation, so you can see exactly what you're paying for.

Do you need insulation removed?

Short answer: only if the old insulation is wet, moldy, contaminated by rodents or animals, smoke-damaged, badly crushed, or blocking work that has to happen underneath it. Dry, clean insulation that's just too thin can usually stay, and new insulation goes on top after the air leaks are sealed. Removing good insulation costs money and adds nothing, so Joe checks before recommending it.

Paramount Insulation has worked in Nassau and Suffolk attics and crawl spaces since 2004. Owner Joe Giordano does every estimate himself: he goes into the attic and crawl space, measures, and uses a thermal camera to see where heat is escaping.

When old insulation should come out

Water damage. Stained, wet or matted insulation usually means a roof or plumbing leak. The leak gets fixed first, then the wet insulation comes out.
Mold. Moldy insulation comes out, the moisture source is fixed, and mold on framing is cleaned up properly. EPA's rule of thumb: the key to mold control is moisture control.
Rodents or animals. Droppings, urine and nesting contaminate insulation. It should be removed, and the entry points found and closed.
Smoke or fire damage. Smoke-damaged insulation holds odor and should be removed.
Crushed or disturbed insulation. Years of storage, foot traffic or old repairs can flatten insulation. Sometimes it can be leveled and topped up. Sometimes removal is cleaner.
Work needed underneath. When major air sealing, new vent baffles, or access for duct and wiring work is needed, clearing the attic floor can be the practical choice.

Vermiculite is a different job

Vermiculite is a loose, pebbly insulation, usually gray-brown or gold. EPA advises treating it as if it may contain asbestos: leave it undisturbed, don't store things in that attic, and hire a professional asbestos contractor if it needs to come out. Paramount doesn't remove vermiculite. If Joe finds it, he stops and tells you, and once it has been handled properly we can come back and insulate.

How removal and re-insulation work

Free estimate. Joe checks the condition and depth of what's there, looks for leaks, droppings, mold and vermiculite, and tells you plainly whether it can stay or should come out.
Written estimate. Removal, disposal, air sealing and new insulation are listed as separate lines, along with anything that belongs to another trade, like a roof leak or wiring.
Protect the house. The path from the attic access is covered before work starts.
Remove. Loose-fill is vacuumed out through a hose to a collection unit outside. Batts are bagged by hand.
Clean and seal. With the attic floor open, gaps around wiring, plumbing, chimneys and the hatch are sealed and vent baffles are added where needed.
Re-insulate. New blown-in cellulose or fiberglass goes in to the target depth. See the Long Island R-value guide.
Clean up. The old material is hauled away and the work area is cleaned.

Attics, crawl spaces and more

In attics, removal happens ahead of new attic insulation. Sagging or wet batts under a crawl space floor can also come out as part of crawl space insulation or encapsulation.

We work throughout Nassau and Suffolk counties, including all of Fire Island and Shelter Island. See our service areas.
