Insulation that has failed
Compressed, wet, mouldy or pest-damaged material cannot be topped up. It has to be replaced with something that works.

What we do
Tear-out and replace in one visit, so the space is fixed rather than patched over.
What it is
Replacement is removal and installation run as one job. The old material comes out, the surface is cleaned, and the new insulation goes in the same visit, which is almost always cheaper and less disruptive than booking the two separately.
It is the right call when what is up there has failed rather than simply run thin: decades-old fiberglass that has compressed to half its depth, material that has been wet, or a crawlspace where everything has fallen off the joists.
Compressed, wet, mouldy or pest-damaged material cannot be topped up. It has to be replaced with something that works.
Moving from fallen fiberglass to closed cell foam in a crawlspace, or from thin batts to blown-in across an attic floor, means the old layer comes out first.
Converting a basement, garage or attic into usable space is the moment to replace whatever was there rather than close it back up.
Process
The same order every time, so you know what is happening in your house and when.
One visit, one written price covering both the removal and the new installation, so there is no surprise second invoice.
Routes through the house and the work area are covered before any of the old material is disturbed.
The old insulation is bagged or vacuumed out and taken away, not stacked in the garage.
The deck, joists or walls are cleaned and any air sealing is done while the surface is still open and reachable.
Spray foam, blown-in, batt or reflective goes in to spec, then we clean the site and walk the finished work with you.

Where it goes
FAQ
Usually, yes. Doing both in one visit means one mobilisation, one set of protection and one crew, and the air sealing happens while the surface is already open.
If it is dry, clean and only thin, it can normally be topped up. If it has been wet, smells, is full of pest damage, or has compressed to a fraction of its original depth, replacement is the honest answer.
Yes, and it is one of the most common jobs we do. The fallen material comes out, the space is cleaned, and closed cell foam or encapsulation goes in so it does not happen again.
