Insulation Removal
When material genuinely has to come out (rodents, mould, water), the special case of vermiculite, what removal costs, and the five-step test that saves most attics the expense.
The independent reference for attic insulation
Most homeowners pricing insulation removal do not need removal. They need depth added over what is already there, at a fraction of the cost. Two questions decide nearly everything: what is on your attic floor now, and what your climate zone calls for.
Every number here is sourced and dated, and when the honest answer is that you do not need the work, the page says so. We do not sell insulation and we do not install it, which is why it can.

The reference, by section
Cost
Installed prices built from checkable parts: BLS wage data, published bag coverage and retail material prices, with every estimate labelled as one.
Types
Blown fibreglass, cellulose, mineral wool, batts and foam, compared on the numbers that matter and on where each one fails.
R-Value
The zone targets, the per-inch charts, and the difference between an ENERGY STAR recommendation, the model code, and what your state actually enforces.
Tools
Calculators that take your ZIP, your attic and your measurements, and return targets, depths and cost brackets with every input sourced.

Start with the decision, not the product
The expensive mistakes in this trade are decisions, not materials. These three guides carry the decisions that show up in real quotes most often.
Remove it, or add over it?
A five-step test. Most attics keep the old material, and the difference is a few thousand dollars.
Is this vermiculite?
How to recognise it without touching it, and why leaving it undisturbed is usually the correct first move.
Is this quote fair?
What an installed price is made of, and the line items that explain most of the spread between quotes.
