Insulation Removal & Replacement in Montgomery, AL

Insulation removal and replacement makes sense when what is already there is doing harm instead of good. In Montgomery that often means fiberglass batts hanging from the floor of a damp crawl space, attic insulation soiled by rats, squirrels or raccoons, material soaked by an old roof leak, or a previous foam job that was sprayed badly and smells or has pulled away.

Why not just add more on top

New insulation laid over contaminated material keeps the smell and the allergens in the house. Wet insulation holds moisture against framing. And in an attic, the old layer often covers the very leaks that need sealing, so it has to come out before the bypasses can be reached. Removal also gives a clear view of wiring, ducts and roof decking.

How removal works

For loose fill, we use a high-powered vacuum that pulls the material through a hose into bags outside, which keeps dust out of the living space. Batts are bagged by hand. Old spray foam has to be cut or scraped off, which is slower. Fixr notes that hand-chipped foam removal can reach about $5 per square foot. After removal we clean the area, seal the air leaks, and install the new insulation, so the house is never left without it for long.

What we watch for

Vermiculite, a pebbly gray-brown loose fill found in some older attics, may contain asbestos and should be tested before anyone disturbs it. If we see it, we stop and recommend testing; abatement, if needed, is done by a licensed asbestos contractor. We also note signs of active pests, since there is no point replacing insulation until the entry points are closed.

Replacing it with something that lasts

What goes back in depends on why the old material failed. If a crawl space soaked the batts, putting new batts back in the same damp air repeats the problem, so the fix is usually a sealed crawl space or closed-cell foam under the floor. If rodents ruined an attic, the entry points need to be closed before fresh loose fill goes down over a sealed attic floor. The quote spells out both the removal and the replacement, so you can see the whole job in one place.
